I recently upgraded from 16.04 to 18.04 using "do-release-upgrade", it went mostly well except for Nvidia related stuff (as expected).

Guessing I should reinstall the drivers cleanly, I did :

$ sudo apt-get purge nvidia*

then

$ sudo apt-get install nvidia-drivers-418 

(My gpu is a laptop Quadro P2000, according to nvidia, it shoud be compatible with the 418 driver)

After rebooting, I find myself in quite a weird situation, where the driver seems to be properly installed (see screenshot), but doesn't seem to be used. For example, while running glxgears, there is no processes registered in nvidia-smi (and the framerate is quite lower than expected with such a GPU) and some graphical things seem a bit laggy. I tried running Starcraft II in lutris (which was running fine in 16.04 with workign GPU) and it was a catastrophy.

Weirder, the drivers actually seem to be loaded by the kernel, as shown below :

$ lsmod | grep nvidia

nvidia_uvm            798720  0

nvidia_drm             45056  0

nvidia_modeset       1085440  1 nvidia_drm

nvidia              17600512  38 nvidia_uvm,nvidia_modeset

drm_kms_helper        167936  2 nvidia_drm,i915

drm                   401408  25 drm_kms_helper,nvidia_drm,i915

ipmi_msghandler        53248  2 ipmi_devintf,nvidia

Oh and the prime profile is set to nvidia

More weird information :

$ sudo nvidia-detector

none

$ sudo modprobe nvidia

#nothingness (outputs nothing, just to be clear)

$ cat /var/log/gpu-manager.log | grep nvidia

Looking for nvidia modules in /lib/modules/4.15.0-1035-oem/updates/dkms

Found nvidia module: nvidia-uvm.ko

Is nvidia loaded? yes

Was nvidia unloaded? no

Is nvidia blacklisted? no

Is nvidia kernel module available? yes

Creating /usr/share/X11/xorg.conf.d/11-nvidia-prime.conf

The nvidia xserver gui only shows options to swich between performance profile (nvidia) to economy (intel), whereas there were a lot of options in 16.04.

I tried :

• Purging again, removing xorg.conf* files, reinstalling the same way


• Same steps, but with .run driver downloaded from nvidia's website


• Different versions of drivers, with always the same results


• Everything suggested here Nvidia drivers installed, but not used
  

Thank you very much for your help !
