Nvidia driver installed but not running

Graphics / Linux Linux
1

I have dell xps15 running ubuntu 18.04 with nvidia geforce 1050Ti
I have installed nvidia driver (390 first and than 430) from the installation it looks like everything went well. When I run nvidia-setting it states I am running GPU also when I run nvidia-prime query it return nvidia But when I do nvidia-smi, I get an output which says

No running processes found

Also if I look at the “about” I see that it runs the intel card.

Any ideas ? Thanks a lot

Done

Looks like you ran into a known GDM bug and are running a Wayland session. Please install and use lightdm:
sudo apt install lightdm
and check if works then.

I tried purging nvidia and than installing lightdm
Still not working and the same error about nouveu

6

Any other suggestions?

7

Please create a new nvidia-bug-report.log while using lightdm.

Here it is,
I think its the same

Ok, now it includes the xorg logs and config files.
It’s an Optimus system and yoou created an xorg.conf, which breaks it. Please delete
/etc/X11/xorg.conf

We are advancing. but still not working
I got nvidia nsight on my computer which was not there before
It still seems to complain about nouevo
you can find attach the bug report

There’s no xorg log included, did you switch back to gdm?

12

not intentionally
at least, how can I check that?

13

please run
sudo journalctl -b0 --no-pager >journal.txt
and attach the output file.

Here it is
again thanks a lot

It’s switched back to gdm which is starting a Wayland session so nothing works. Please switch back to lightdm using
sudo dpkg-reconfigure lightdm
choose lightdm on the prompt, reboot and create a new nvidia-bug-report.log afterwards.

Logs look good now but somehow the needed xrandr commands to use the nvidia gpu are not issued so you’ll have to do some modifications by hand. Please change the lightdm config like here:

I tried this , the resullt was that I couldn’t log into my computer. So I had o delete the /etc/lightdm/lightdm.conf file so I can start again.
By the way, both files were not existing before

I’m really puzzled by what’s going on on your system.
Please post the output of
xrandr --listproviders
and
xrandr --verbose
when called from desktop.

xrandr --listproviders
