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:
bugs.launchpad.net/.../1585884
Autorandr script is here: github.com/.../

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.

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.

I plan to connect a USB DasKeyboard, External 23'-monitor, and it would be nice if it have another USB port or two for an external hard drive and wired/wireless mouse.  Any suggestions would be greatly appreciated. Oh, as long as you're here: I've noticed that my Crucial SSD drive is not nearly as zippy fast as it was when first installed. Any suggestions? (I'm assuming the guilty culprit is Windows 10 upgrade after upgrade.) Thanks everyone!
