[SOLVED] Can't adjust video resolution after 18.04 upgrade

[kenj70]

I just upgraded from 16.04 to 18.04 and my video size is 640x480

I can't figure out how to change the video size. I tried running the nVidea app but it won't come up. Stuck.

it sounds like your display driver did not live through the upgrade , check that the driver is still installed and the module got rebuilt for the new kernel.

is nvidia installed , check ,,,,,,

Yes, nvidia installed, modules loaded.

Tried:

[FONT=monospace]kdesudo nvidia-settings   
libpng warning: iCCP: known incorrect sRGB profile

ERROR: Unable to load info from any available system

[/FONT]

Should I try to uninstall the nvidia drivers?

Edit: I just checked and there are three updates for xserver and one for xwayland waiting for me. Maybe doing the update would work? Or wait?

[kenj70]

Ran this:

$ sudo ubuntu-drivers autoinstall

[FONT=monospace]$ ubuntu-drivers devices
== /sys/devices/pci0000:00/0000:00:03.1/0000:0b:00.0 ==

model    : GK208B [GeForce GT 710]
driver   : nvidia-driver-390 - distro non-free recommended

Now it works fine! What the...?
