P50 docking station

Hi!
I have a Latitude E7740 that runs Ubuntu Xenial (16.04). I dock it to a "Dell EURO2 Advanced E-port II" docking station. 
If I boot it in the docking station, everything works fine, and I find all my two DVI-connected monitors. 
However, if I undock, then put it into the dock again while running, it fails to enable the screens. I'm using a script called autorandr for switching between display modes - it uses xrandr. It tries to run:
xrandr --output DP1-1 --gamma 1.0:1.0:1.0 --mode 1920x1200 --panning 0x0 --pos 0x0 --rate 59.95 --reflect normal --rotate normal --output DP1-2 --gamma 1.0:1.0:1.0 --mode 1920x1200 --panning 0x0 --pos 1920x0 --rate 59.95 --reflect normal --rotate normal
But the X server responds with:
X Error of failed request: BadMatch (invalid parameter attributes)  Major opcode of failed request: 140 (RANDR)  Minor opcode of failed request: 21 (RRSetCrtcConfig)  Serial number of failed request: 48  Current serial number in output stream: 48
Running this exact command after booting in the dock is doing the right thing, but after undocking then docking, it doesn't work.
Any ideas here? I have updated to the latest BIOS version.
Problem also reported in launchpad with lot's of debug info, here:

Autorandr script is here: github.com/.../

Hello Does anyone know which docking station is compatable for a G50-80? Thanks Jill

I'm looking for a relatively inexpensive docking station for my dell 1420 laptop and didn't have a clue where to start. Well, I did start looking but everything I found was well over $100 dollars so I chose to ask the forums where everyone knows about computers.

I want it to be able to hook me into my 17in lcd, printer, mouse, keyboard, ethernet (internet), and power.

Thanks! I look forward to your suggestions.

I have a Dell D620. When i connect to my docking station. I can not access my my wireless, air card or lan connection.

File Transfer - Help Wanted

It will be from the old computer running Windows XP to a new computer running Windows 7.

The old computer has files which I have accumulated over a number of years, it is a mixture of those used rarely, used frequently and junk.

The chances are some of the files will never be used again, but they just might be wanted at some future date. I am therefore reluctant to scrap anything. Neither do I want to put a lot of possibly unnecessary files on the new computer.

I need to be able to search the old hard drive and recover a file if it is wanted.

The old computer is about 9 years old and is slow and may not be worth upgrading.

I now have two computers and one monitor and I am not sure what would be the best route.

I have not used a Docking Station before but thought this could be a possibility, on Amazon I found:

Any ideas would be a big help. Thanks.

Well I now have the image on what I will call the G: drive and removed the IDE ribbon from the master hard drive and pluged into the removable hard drive hoping it would boot and this would be all over but when I boot I get a message NTLDR is missing. Am I missing something here?
Any help would be greatly appreciated.

HD Docking station

Hi,

I bought an external HD recently & transferred from my PC's HD a 50GB backup file but, when I tried to see the stored file it did not work & had to return it.

I would like some advise on the item below, if anyone is using it.

If I put a HD in it can I transfer files from my PC to it?

Hi,i need to know what dock is compatible for my hp spectre. whether zbook dock is compatible for my thunderbolt 3 and USB-c?I need a dock that can do two display output.is dell thunderbolt 3 dock compatible?

I have a client that has a hp laptop and accompanying docking station. The usb ports on the docking station suddenly stopped working. I replaced the docking station with a brand new one, worked for about 2 weeks, then crapped out again. While in the docking station, the hp usb ports work fine, only the usb ports on the docking station are out of order.

JohnWill gave me a usb hack about a year ago, and I ran that, and while it then recognized the the 'new hardware', it stated I had to reboot; rebooted, and nothing showed up.

Any ideas? The hardware is not local, but if push comes to shove I can get the make and model of it.

Hi,Is there a docking station available for spectrex2?I don't seem to find one.If not which usb docking station would you recommend for spectre 2?Thank you very much

Is there a docking station that i can use with this laptop?

I have two users who both Dell Latitude laptop computers. When they power up the computers, they are able to set their graphics to the desired level (1280x760). If they power up the computers while on a docking station they are able to set the graphics to a different level (1024X768) and this works fine.

The problem they have is if the machine is already powered on (1280x760) and the dock the system, the graphics on the external monitor will go to 800x600, totally disregarding what they had set the graphics for. They are able to change it back and it is fine again.

Why does this only occur when the machine is powered on already and they are trying to dock it? Is there some setting that needs to be changed?

I appreciate your help!!
