Installing nvidia drivers and using nvidia graphic card

[CelticWarrior]

Ok, seems fine.

Now you can open Additional Drivers and select and install the recommended driver version. Reboot and make sure Secure Boot is disabled.

OK, so I did, and it asked for passwd, worked for a while, I restarted, and I get this, seems nvidia card is still not in use, or am I missing something ?

Are you absolutely sure Secure Boot is disabled?

However, the driver seems to be present and (properly ?) installed

Yes, I checked that Friday with the computer service of my university (I don't have the bios paswd) : secure boot mode was disabled...

However, could there be other bios options that get in the way ? I am starting to wonder, because I really don't understand what's going on...

[CelticWarrior]

Not having the password doesn't help, at all...

There are other settings that you may need to check/change. Namely, the dGPU could be disabled which perhaps would explain the unclaimed status.
But try opening Nvidia X Server Settings and select the Nvidia profile and reboot. Maybe that changes it.

[marcb2]

sudo prime-select nvidia
Info: the nvidia profile is already set

Yes, I am starting to think something along the lines of bios settings... there is a switchable graphics option that can be a nuisance it seems.
not having bios passwd is a pain... i hate that.
Anyways, thanks a ton for your help : at least the situation seems more sane...

If that is a bios problem and I correct it, though, could there be other things to change or should I re-install after modifying the bios, in your opinion ?

marcb2, please use code tags in preference to quote tags when posting terminal output. It will better maintain the readability of your posts, also feel free to edit previous posts should you wish to add information before a respondent posts again. Thank you.

[marcb2]

Oh, sorry for the disturbance ! Thanks a lot for your indications ! I will, as of now...

[marcb2]

OK, so I finally got the BIOS passwd removed and can play with it at will... I disabled Switchable graphics in the bios, took all the steps again as indicated above and re-installed nvidia driver, and now I get this :

sudo lshw -numeric -C display

  *-display UNCLAIMED

which is weird : the intel card is gone and the nvidia unclaimed... what the heck is going on ? Would anyone have any idea how to deal with this ?

And I get this :

 >  lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation TU117GLM [Quadro T1000 Mobile] (rev a1)

This looks like nvidia finally took over, didn't it ?

However, nvidia-settings does not even work and says something nasty :

nvidia-settings 
[sudo] password for bletry: 

ERROR: NVIDIA driver is not loaded


ERROR: Unable to load info from any available system

Digging a bit more :

inxi -G
Graphics:  Card: NVIDIA TU117GLM [Quadro T1000 Mobile]
           Display Server: x11 (X.Org 1.20.8 ) drivers: fbdev,nouveau (unloaded: modesetting,vesa)

           OpenGL: renderer: llvmpipe (LLVM 10.0.0, 256 bits) version: 3.3 Mesa 20.0.8

So it looks like in spite of installing nvidia driver... it just didn't install at all and drivers that are supposedly blacklisted are used nonetheless... What is going on here ?? Any help would be much appreciated...

[CelticWarrior]

It really looks like Secure Boot is still enabled.
