Razer mouse sensitivity out of wack on Linux

Q: Razer mouse sensitivity out of wack on Linux

I got a left handed Razer Deathadder mouse I installed the drivers on Windows and it works great. Sadly there aren't any drivers for Linux and the mouse sensitivity is all messed up. In the settings I have 0 acceleration but it still moves to fast at the slightest movement. Any solutions?

I recommend downloading and running DAP. It can help sort out any driver and firmware related issues on your system

It's worked out well for many of us in the past.

Hi. This is gonna sound odd but every time I move my mouse real fast it goes out of control. If I don't move the mouse the cursor stays but with one little twitch and it is half-way across the screen again. This also tends to happen in Linux but Win2k is the worst. If I don't move it for about 3 seconds it goes back to normal until I move it fast again. And I am not even moving it that fast!!! Please help. Thank you.

I have a Razer Copperhead gaming mouse and i installed the application that allows you to customize it. The computer at startup recognizes the mouse in the USB port however the application that controls the mouse does not. What might be the issue?

I'm a pretty big gamer, and I play a lot of games (TF2, CS:S, COD4, COD2.) Everything really.

So I think it would be very beneficial to have the exact same sensitivity in all my games, so I don't have to adapt to a new one every time, now I know Steam games have a number for it, but I play non-steam games and don't really know what the number is for. Is there any way to make my sensitivity in the games the same in each one?

I am looking for a utility which would change the mouse sensitivity temporarily. For example, I would like to hold down the control key and have the cursor move a smaller amount for a given mouse movement.

I am using Windows XP Pro

Does anyone know of such a utility? Thanks.

Hello there! So i just finished formatting my laptop and came across with this weird problem with mouse sensitivity, i have already modified the mouse sensitivity through control panel and i'm pretty sure i clicked "Apply" before closing the
settings, but whenever i launch games like league of legends, dota 2 and gta san andreas, my mouse sensitivity suddenly changes itself, i have no idea why does it happen, i had to alt + tab and then change the mouse sensitivity again through control panel,
the problem is not my mouse. Answers will be appreciated.

I wasnt sure whether to post this in the games forum or the windows xp forum, but considering the "problem" extends past gaming and into windows desktop, I am assuming it is a windows thing.

I am a somewhat competitive gamer so mouse "feel" is just as important to me as actual mouse sensitivity, so I notice when things change with my mouse.

In order to achieve what I consider to be optimum mouse sensitivity and feel I use an mx510 mouse, mouseware 9.80 drivers, with windows set to the 3rd bar from the left. I also apply the 'cpl mouse fix' registy patch to disable the built-in acceleration of windows xp. This has always had the correct feel for me.

Recently I attempted to use v_sync in the game I play but it wasnt for the best for two reasons: 1) I ended up getting a bit of tearing because my system cannot maintain fps equal to my refresh rate and more importantly 2) because the mouse ended up feeling "sloppy". I read online that with v_sync enabled that your mouse "feel" is changed depending on what kind of performance your system is capable of as your frame rate gets locked to your vertical refesh rate and mouse position is rendered differently:


With vsync on, the game renders a frame, then idles until the vertical retrace happens (which might take up to 8 ms with a 125 Hz refresh rate, even longer at lower refresh rates). No mouse movement is registered in that time. Depending on framerate an... Read more

A:windows mouse sensitivity...

I have the same trouble too sometimes. I always loved the basic Microsoft Mice with a wheel. I have had only 1 logitech mouse and it was a ball mouse almost 50 dollars for nothing. Anyways the only thing I can think of is to uninstall the drivers for it and see if it will work without those drivers and run like it is with the basic mouse ps/2 port driver. I believe that my other mouse that was a ball mouse worked a little better with it like this.

I am using a gaming mouse which has a maximum setting of 3200 DPI. I have it set to 3200 DPI. The game I am playing has a slider to adjust mouse sensitivity and that slider is maxed out. With that said, the sensitivity/speed is still too slow for my liking.
Is there anyway that I can speed up the mouse sensitivity/speed in game. Any help would be appreciated. Thanks.

ok, my mouse sensitivity seems to change back and forth on its own, the sensitivity slider is always in the middle and doesnt move, but acts as if its on the lowest setting, and then bounces back to normal, then back and forth at random, it switches on average about once every 15 minutes, sometimes it will take a fit and happen much more often.

Are they're any programs (freeware preferred but not required) that will allow me to tweak my mouse's sensitivity?

I recently had a Microsoft Blue laser mouse, 800dpi and its seen a lot of use, and the buttons don't work so well anymore.
So I bought a Optorite ML100 laser mouse, 1600dpi and this is just way too fast, and I would like to adjust its sensitivity if possible. Just barely nudging this mouse and the pointer jumps like 2"-4" or so across my screen.

Just as the title says

Hi guys I got a new mouse a couple of days back, it's one of those fancy Razer mouses with 12 buttons on the side that is used for gaming and stuff. I have an issue when I try to use usb 3.0 instead of 2.0 ports. ( my tower only has like 2 2.0 ports so I try to use those for other things ) I am trying not to buy a usb hub before somebody says it

On games ( fullscreen or Windowed ) quickslot controls where you can use the numbers on your mouse I can't use the 3.0 port as it won't recognize the side buttons but it will on the 2.0 port.

I am guessing this is a driver problem but I am unsure. Neither the native mouse driver for Windows nor the fancy Cloud Synapse driver 2.0 works. Is there another one I don't know about or is there a fix to this?

A:Razer Mouse - USB 3.0 port using 2.0

It could be that the 3.0 port is being provided by an add-on chip on the motherboard, rather than native to the motherboard itself, which could explain the compatibility issue.

While I understand that your ports are limited, plugging the mouse into a 3.0 port is a total waste of bandwidth and is not going to have any kind of advantage over using the 2.0 spec. Can't you just unplug one of your existing devices that is occupying the 2.0 port, and use the 3.0 for that to free up a 2.0 port for the mouse?

From my own past experience, using a 3.0 port for a mouse has occasionally caused abnormal mouse behavior.

You could also try looking in BIOS for an option to set your 3.0 port to "legacy" or the 2.0 spec. Some BIOS' will give you that option...

So i've bought a new asus computer, for gaming which is pretty much the only thing i use the computer for. The problem is that now whenever i'm playing my mouse sensitivity is completely different, which makes no sense, since the sensitivity is the same for everyone.

For exemple in Counter- Strike GO (i've tried a few fps games and the problem is the same in all of them)

With my old computer: 2.8 in game sensitivity / 400 cpi's/ 6/11 on windows

Now with new computer: 0.9 in game sensitivity / 450 cpi's / 6/11 on windows

The problem here is that i just don't feel that the sensitivity is working properly and after 1 month i still couldn't get used to it, it feels like i'm playing with accelaration and the sensitivity just isn't constant and for an fps it just doesn't work.... and since i take the game a bit seriously it's a bit annoying, because i just can't play like i used to.

Another exemple is that with 0.9 sens i'm able to do 180 degrees which i would do with something between 2.4/2.8 in my old computer, but if i go higher than 1.7/1.9 i'll do a complete 360 degrees, which is weird, because everyone that i know, that uses them same mouse dpi's and windows sensitivity plays with more than 2.0 sensitivity which is quite normal...

(Relatively) new build, haven't had problems with the mouse before. I have the Logitech MouseWare 9.80 software installed (specific to the MX510) and as odd as this sounds, the sensitivity is inconsistent. My mousepad is black, microfiber-type texture and I haven't had any problems with it before. If I open up MouseWare and then press OK the sensitivity returns to normal, but after that, usually after opening or closing (it seems kind of random) windows, the sensitivity will decrease (I think it is actually turning off acceleration). Logitech's support site is too broad to be of much use, so any help is appreciated, either suggestions or solutions. Thanks.

I'm on XP Pro SP2 (I was using XP Pro SP2 on an older computer with this same mouse and mousepad, no problems).

A:Logitech MX510 Mouse sensitivity inconsistency

I find the same thing... especially with the fast-scroll buttons on my MX510 - sometimes they jump pages properly, sometimes they go REALLY slow.

Just thinking about it now, I wonder if it's related to some other USB device I have plugged in.. then again, I have the mouse plugged in to a KVM with a USB-PS/2 adapter, so that's probably not it in my case. I have tested other pointing devices as well (assorted other mice, a Gyro mouse, my ATI RemoteWonder) and it's possible a residual driver is causing an issue...

I made the mistake of buying this mouse, and luckily I managed to avoid using the Synapse 2.0 software that they pushed via Windows Update at me when I plugged the mouse in.

However it still installed drivers and apparently the mouse uses this .dll called 'RzCoinstaller.dll', whatever that is.

I still have an old Logitech bluetooth mouse I was trying to replace with this mouse... however I am considering chucking out the Razer due to Razer's hardware and software being rather overpriced low quality garbage and I worry about the drivers effects on my computer given the datamining scare with Synapse 2.0.

I intend to possibly replace it with a Steelseries Sensei or a Corsair Vengance M95 mouse, but how do I uninstall the Razer mouse safely without affecting the Logitech mouse? Cause apparently if a mouse still uses one of the drivers it will leave that driver alone if you uninstall via Device Manager?

I just want to be sure to get rid of Razer's drivers before I buy the next mouse first.

So anyone got a guide on this or...?

A:How do I uninstall a Razer Deathadder 2013 4G Mouse?

Hello IllusionaryInno,

how do I uninstall the Razer mouse safely without affecting the Logitech mouse?

The easiest way is to just unplug your Razer mouse and replace it with the Logitech one. Once the device isn't being used anymore, the driver won't be used either.

After switching mouses, you can do the following to remove the device and corresponding driver from your system;

Hit WinKey+X on your keyboard, and from the pop-up menu, select Device Manager.In the Device Manager, click on Mice and other pointing devices.In the drop down menu, right click on your Razer mouse and select Uninstall.A new window will pop up. In this window, click on Delete the driver software for this device.Now follow the on-screen instructions to remove the driver and restart your machine when asked to do so.
And that's it. Now the driver from your Razer mouse will be completely removed.
I don't know for sure with Razer, but you might also want to check the Programs & Features menu to see if there are any left over programs in there. To do so, hit WinKey+X on your keyboard, select Programs & Features from the pop-up menu and scan the list for any Razer software.
If found, right click the entry and select Uninstall. Then follow the on-screen instructions and restart your machine afterwards.

Cause apparently if a mouse still uses one of the drivers it will leave that driver alone if you uninstall via Device Manager?

Hey all
I've got a Razer copperhead that for some time now the factory software has been unable to 'find' on my desktop, but the mouse worked fine otherwise. I took it with me last weekend to use with my laptop and EVERYTHING worked, the configuration program, the on-the-fly sensitivity adjustment, everything. Unfortunately, I got spoiled, and decided I wanted that level of functionality using the mouse on my desktop, so I upgraded the firmware, having already tried everything I could think of on the desktop. Nothing changed while using the mouse on the laptop, but when I plugged it back into the desktop, it lit up, but did nothing. Clicks, movement, everything gets no response.
Any ideas?
I've upgraded the mouse drivers (which fails because they can't 'find' the mouse)
I've upgraded the motherboard drivers
I've upgraded the bios
In the device manager it says the drivers are not installed, but every time (no matter what else is plugged into my USB ports) the wizard says it was unable to complete because "the name is already in use as either a service name or a display name"
To compound the issue, I installed a VPN client, Hamachi, just before the mouse failed, which I have since uninstalled
TIA y'all

Oh yeah, the laptop is a Dell Inspiron 1520, and both it and the desktop are running XP Pro

So as the title says, when I plug in or plug out my razer deathadder, my computer will automatically go into a BSOD. ALL THE TIME. The only time this does not happen is if I plug it in before startup and after shut down. I have made a thread a while before, on the topic of random BSOD and there were multiple offenders which I believed WERE NOT the problem. Now, I do know the exact specific problem. I can recreate this problem any time I want to. The BSOD range from IRQL driver less or equal to, to ntfs.sys. The problem is WITH the mouse and my laptop. How do I fix this? I have tried both the drivers for the deathadder and the one labeled windows. The USB port works with other devices, iphone, cooling pad, etc. But, it seems to not be compatabile with the razer deathadder? THIS IS RECENTLY HAPPENING. I had no such problems like this before. More information can be given. But I pretty much described the cause, that I do not know how to fix.
EDIT: And also what is disk queue length and how can i lower it ( or raise) whichever is better?

Razer DeathAdder drivers were known to cause BSOD's a while back. If you have older drivers installed, this could be the cause. Please update your drivers from the Razer support website: Razer Support

The average disk queue length is 3. The disk may be at its maximum transfer capacity due to throughput and disk seeks

Then ensure that you have the latest drivers from the storage controller manufacturer
Then ensure that all of your programs aren't demanding excess activity from your hard drive (shut down any programs that aren't necessary).

I got the logitech G5 mouse.

It started few months ago, it never happend before and i never had this problem even when i had 10 FPS in games, suddenly my mouse started to act weird
and at high fps it messes up my sensitivity randomly and diffrently X goes slow Y goes fast.

Its not mouse delay lag, when i play with higher then 40 fps it never happens and the sensitivity is perfect but at around 25~30fps the reaction isnt that sharp and its like my DPI drops to 1000 from 2000 for few seconds
then goes back to 2000 randomly and i know how the low fps affects the mouse and its really not it, its like my setpoint options going nuts or something.
Sometimes it even go wierder like moving the crusor left goes 400 DPI right up and down are 2000.

The mouse itself is clean and the laser is on a cloth mouse pad same as it was for the past 12 months i had the mosue without any problems.

Explained in DPI so you'll know what im talking about regarding the sensitivity levels so ignore it.

Please tell me what could cause this, I suspected that it is the drivers or the CPU but i already updated the drivers to the latest version and the CPU doesnt reach 100% while that happens.

A question about the deliver mouse (no wireless) with USB connection. By a minimum pressing on the sroll wheel, it activate by itself de "tact switch" to activate the Microsoft app "Auto scroll" modus.  Mostly without the knowledge from the user. As a result into (from view of the customer) a strange behaviour of his PC.  Study the Autoscroll app and you understand what I mean. Read the forums with a lot of complains about this item.Example: Help, my PC make me crazy.......... Reason: The mechanical pressure resistance on the scroll wheel is negligible. Therefore,  I open the mouse by myself andI was a little bit amazed  because HP used for the "tact switch" component (scroll wheel pressure detection) the most sensitive selection (minimum pressure needed to make contact). I replace it into another type (red color) and from now on it is a magnificent example how to use it conscious. The identification (mechanical pressure) from these components are to be  recognize on the form and the top bottom  color. Also the "click" noise on the original product is almost not audible by the customer, therefore the confusion........... My question is:   Is this a mistaken product (mouse) and is this topic well-know in the HP community ?With kind regards,Trumb

like are you able to say for instance open i-tunes with one of the extra buttons?

just wanna make sure before i buy it

I have searched help forums far and wide without finding a solution to this problem, or even a similar description. Every 10 minutes or so, my mouse will lag for 4-7 seconds, and then correct itself. What I mean by lag is that it will suddenly appear to me moving more slowly than before, but will still follow whatever direction I am currently moving my mouse. Clicks done during the lag will happen at the position the pointer was at when I clicked them, but a second or so after I clicked. During the lag, the movement of the cursor appears stuttered and jittery, as if I am dropping frames, yet any action on the screen continues without any such interruption. At the end of the lag, the cursor suddenly jumps to a new location, presumably where it should have ended up after all the inputs I gave it during the lag. My mouse is a Razer Abyssus, sampling at 1000 Hz and set to 3500 dpi. It is a wired mouse on a USB port.
The lag does not occur in sync with any obvious system traffic, and does not affect any other activity, such as keyboard input or talking over Ventrilo or Mumble. It can happen just as easily, and last just as long while navigating webpages as when I'm playing a CPU intensive game. I have tried uninstalling and re-installing drivers, changing the USB port, and shutting down multiple background tasks such as iTunes and Adobe checking for automatic updates. It started about a month ago, and I don't recall installing anything that may have caused it.

Hi everyone,

This is such a great forum by the way - I haven't used it before but I've read a few posts and everyone seems so helpful! I'll try to make my situation as understandable as possible.

Firstly, the required specs:


? Windows 7 (Ultimate I think)
? 64 bit
? Brand new computer. I installed XP. Then reformatted to install Win7.
? Full retail version
? ~3-4 years
? ~1-2 years
? Q6600 2.4Ghz overclocked to ~3.2Ghz
? nVidia 8800GTS 320mb
? Asus P5E x48 (I think) - with Rampage Formula drivers
? Antec TruPower (not sure) ~500W

Have always used my Razer Lachesis mouse (used to be on old XP firmware/driers)
And then I installed Windows 7 (and I probably updated to the latest Windows 7 drivers)
I recently decided to upgrade to the newest firmware/drivers from the official Razer Lachesis page.
The firmware installs fine.
Upon installation of the driver, I got a BSOD.
Upon restart, it said I had a corrupt file of a 3 letter (.sys file) which I forgot. Something like 'cng.sys' maybe. It booted up fine though using the recovered option.
The Razer Configurator software didn't install and there was no more Razer folder in Program Files (but there used to be).
So I believe the drivers didn't install.
I try again, and I keep getting BSOD with some dump where the number counts upwards.
So I'm pretty sure it's because of the new mouse driver I'm trying to install for my mouse. Not sure what's the conflict though. Any help muc... Read more

A:Razer Lachesis mouse driver installation causes BSOD

Yah, from the past two crashdumps (both dated April 5), it's definitely the mouse drivers (Lachesis.sys reported for both), and it's performing the same exact thing. I can't tell without a kernel dump what's actually going on, but whatever it did, it looks like it's corrupted the crashdumps as well (lots of information is zeroed).

Are you installing the correct drivers for it? You are installing the Windows 7 64-bit drivers, yes? I've noticed as well researching this that many other people are experiencing awful compatibility issues with 64-bit version of Vista and their Lachesis, and I'm feeling that this incompatibility has transferred over to Windows 7 as well.

Further inspection has me eyeballing a particular driver that kept unloading itself, thrice in each crashdump, that being LVUSBS64.sys. I know from research it's related to a USB Logitech device, most likely a webcam or speakers, but not entirely sure on that. You should determine this based on your own personal PC setup. Whatever Logitech item you have, you may wanna go into Device Manager and right click the device then click "Disable". Restart the PC. Then install the Lachesis drivers and restart as usual. If it still crashes, just simply consider the Lachesis as being incompatible to Windows 7 environment. Otherwise, it may very well be the Logitech device doing something funky and the Lachesis drivers have been left with the bag.

Forgive me if this is long, but I have spent a whole day trying to figure this out and have hit a brick wall. I'm running XP SP2, and recently bought a brand new Razer DeathAdder mouse from an online shop. Upon plugging it in and installing the drivers from the CD, I noticed some weird behaviour. The mouse button was being clicked randomly without me touching any buttons, but only while I moved the cursor around. So I opened a file with some text and moved the cursor around over the lines so I could see what it was doing exactly. As I moved it around, 10-20 times a minute it was randomly clicking the cursor onto a different line, and running the macro I assigned to one of the side buttons (being just a press of the letter 'a'). The drivers on the CD were the latest, however the firmware was v1.25. I wasn't going to update it to v1.27 because it only fixed one unrelated bug with waking a computer out of sleep mode. However, I decided I would update the firmware just to rule it out. First time it seemed to hang and failed, I must have pressed the wrong key in the wizard. Second time it failed again. This time I thought I bricked it since the mouse lights went off; plugging it in again did nothing. Third time I thought maybe I will kill the driver exe's running in the background, and try again. It flashed and updated the firmware successfully.

I still had the same problem with the random clicking for a split second. I thought perhaps there's a driv... Read more

A:Brand new Razer mouse acting slightly weird

You might check the manufacturers website for updated software.
Sounds like you found a bug,and there may be an update.
Could also be bad mouse hardware,as some of the functions may not be activated
until the software is installed.

So I just updated Razer Synapse on my desktop PC once it was complete I lost the ability to use my Naga mouse and keyboard (not Razer). I pressed the power button and my PC immediately shut down, which I thought was a little odd since I did not hold the power button....Anyways I restarted the PC and when it booted up the resolution was changed and I was not able to utilize the mouse or keyboard. I tried starting the PC in safe mode and it still had the same issue. The mouse and keyboard will function up until windows 7 is loaded. The only thing I think it could have been is that while synapse was updating AVG popped up saying it removed a potentially dangerous file, could that have been part of the synapse software?...Any help fixing this issue would be appreciated!

A:Updated Razer Synapse, now Keyboard and Mouse will not function.


You could simply do a System Restore from a command prompt - Microsoft Windows Help to a restore point prior to the upgrade was done.

hello!i can cheaply get a razer deathadder and a razer lycosa keyboard
instead of logitech gaming mouse g400 and microsoft digital media keyboard 3000
can buy both for 400kr 200 each. original prize of the death adder is about 600kr is it worth the money?

A:Is it worth changing mouse from logitech g400 to razer deathadder?

Sisrace, Just my opinion. But, gaming keyboard and mouse is really a personal prefrence. The prices you quoted are very close to retail prices in the US, depending on which model they are. If you have the opportunity, I would try to use them for a couple of days before purchasing. The Lycosa appears to be discontinued here. I guess, all I am saying is that for gaming, they are personal preferences. For the price you quoted, it sounds like an OK deal to me. But, that's no guarentee you will like them in gaming. Personally, I have a Logitech G510 and G500. If they both died today I would have a G510 and G500 on the way tomorrow. Others feel the same about their Razor products.

Razer has now let loose a left hand version of its popular DeathAdder mouse claiming that it is the first rodent specifically aimed at left-handed gamers


A:Razer delivers DeathAdder mouse for left-handed gamers

Hey, my fellow Lachesis users. I have the 4000 dpi version, 2 actually. If I program one of the side keys to any single key I have a problem. Do you?? I use the front right side key for melee. Try ths. Program any side key to some single key. Then open word or notepad. get the curser ready to type. Press and hold the left mouse button and as your holding it press and release the side key - the let go of the left mouse button. It's a problem for me because while gaming if I am firing a weapon while being rushed I sometimes melee befor letting up on fire. Anyway, 3 of 3 Lachesis mouse I have tried this on are the same. Hold left mouse while press and release side key programed as any single key, then release left mouse and that programed key is acting like it's depressed until you press any of the side keys again. True????

Is that normal. Can I set it up so it does not work that way?? I tried doing a macro but that way the macro won't interupt the fire/left mouse.

Uploaded with ImageShack.us

there is my Lachesis config. I tested it again and found that the programed button remains like it's being depresses until you press any of the other PROGRAMED SIDE buttons. The 2 behind the wheel will not un-stick the programed key and for a side key to un-stick it, it can't be off.

Hello guys. Here is my issue with the fn button - no app recognizes it (except lenovo specials).I am not able to use it as an entry key for extra buttons function (it's called hypershift on razer mouse software).Razer IT claims that "hypershift" should work with default Fn button.  Is there a way to make different apps recognize Fn button entries?then it could be a simple solution for any additional keys combination.  Many thanks
