I shortly installed Ubuntu on my Notebook. Standalone everything works like a charm, but if I connect it with the docking station the displays will not work like they are meant to be. So after three hours of searching and trying I need help or have to switch back to Windows.
Here is what I have:
- DELL Precision M4800 Notebook
- NVIDIA Quadro K2100M videocard
- three identical external displays, all 23''
- docking station (DELL Port Replicator)
- Ubuntu 14.04.1 LTS 64 Bit installed
I want to use two displays with DVI and the last one with VGA (because the dockingstation only have two DVI ports). One of the displays is turned upright and now there should be an extended desktop over these three external displays, the internal display can be turned off in the dockingstation.
From the DELL support page I have installed every driver that I have found, also from the NVIDIA site. Now I have "NVIDIA binary driver - version 331.113" and nvidia-settings installed. But when I try to configure the displays (either with the display settings in Ubuntu or with the installed "NVIDIA X Server Settings") the desktop will be distorted and moves around when the cursor gets to one edge.
Does anybody have a solution to solve the problem? Or a general hint in which direction I should search to get closer to a solution?
If more information are needed, feel free to ask, I will provide as many information as I can.
