ubuntu - nvidia driver impossible to use precision 7750
Hi,
I have tried in all sorts of way to use nvidia's driver to work to no avail. I have a Dell Precision 7750 under ubuntu 18 and a Quadro T1000 Mobile. For some reason, the Nouveau driver takes precedence, even though Secure boot is disabled, switchable graphics is disabled and so on... is there some bios parameter I should be aware of that can prevent nvidia's driver from working ? Any help would be extremely welcome : I have been bugged by this for about 2 weeks now and nothing seems to work...
Have a good day,
Marc

Sorry, I don't understand your answer... do you mean I should do additional research ?

mblet,
I meant that I will research this for you by asking our Ubuntu engineers and reply back to you.

You can click here for possible resolution or reach out here on the Ubuntu forums.

mblet,
I am sure you have tried uninstalling both and reinstalled them back in the system.

mblet,
Have you tried enabling the switchable graphics to on?

Thanks but I already tried a few solutions suggested on the ubuntu forum (see here : https://ubuntuforums.org/showthread.php?t=2453253&p=13998194#post13998194) and apparently, people just don't know how to deal with my situation... and I already tried everything that's on the other link, to no avail.

It was initially on, I tried switching it off. It had the effect - apparently - to make my intel graphic card go away. But no improvement on the drivers side...

I have tried something like 10 combinations, I'd say, with and without these two options, using ubuntu graphic installer or nvidia's shell installer... to be honest, I am a bit lost... I've never seen a problem like this before (I am a humble mere user of linux since 15 yrs, but a complete newbie under ubuntu, used Fedora before...).

mblet,
I contacted our Ubuntu team and they suggest the following information.
Try blacklisting Nouveau, although you say you tried running the shell installer from NVIDIA, which should do this automatically. You might try disabling “switchable graphics” in the BIOS as well. (it looks like you tried this, but not with explicitly blacklisting Nouveau).

Hi,
Thanks a lot for your message and for not giving up on me ;-). I am going to retry this, but as a matter of fact, I had already blacklisted Nouveau before, as I have this :
more /etc/modprobe.d/blacklist-nvidia-nouveau.conf
1 blacklist nouveau
2 blacklist vga16fb
3 blacklist rivafb
4 blacklist nvidiafb
5 blacklist rivatv
6 alias nouveau off
7 alias lbm-nouveau off
8 options nouveau modeset=0
