Bug Description
Upgrading Xubuntu 17.10 to 18.04
Using Nvidia Quadro K4000 Graphics Card with proprietary driver and dual screens
After the upgrade, which went smoothly, only one screen was recognized and the system was almost unusable. The Xorg process was running wild, consuming almost all the CPU. It was difficult to move the cursor and all screen updates were incredibly slow. I suspected the graphics driver and saw that the Nvidia driver had been replaced with the X.Org Nouveau open source driver. I checked the available drivers with:
7-> ubuntu-drivers devices
== /sys/devices/
modalias : pci:v000010DEd0
vendor : NVIDIA Corporation
model : GK106GL [Quadro K4000]
driver : nvidia-driver-390 - distro non-free recommended
driver : nvidia-340 - distro non-free
driver : xserver-
After reinstalling the proprietary driver with the command:
8-> sudo apt install nvidia-driver-390
and rebooting the system, everything was back to normal.
I have had similar driver replacement problems with past upgrades. Why doesn't the upgrade register and reinstall the proper graphics driver? And why is the default driver so abysmal with a standard Nvidia card? This should be fixed in future upgrades.
