nvidia optimus [Solved]

[mg979]

Purged/reinstalled with tools, no bumblebee:

Code: Select all

$ inxi -G
Graphics:  Device-1: Intel CoffeeLake-H GT2 [UHD Graphics 630] driver: i915 v: kernel 
           Device-2: NVIDIA GP107M [GeForce GTX 1050 Mobile] driver: nvidia v: 460.91.03 
           Display: x11 server: X.Org 1.20.11 driver: intel resolution: 1920x1080~60Hz 
           OpenGL: renderer: Mesa DRI Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 20.3.5 

$ nvidia-run-mx nvidia-settings

ERROR: Unable to load info from any available system

we probably need the

/var/log/ddm.log

file and also the output of both

Code: Select all

nvidia-detect

and

Code: Select all

nvidia-detect-mx

also, if you have switched to the "intel" graphics driver in mx-tweak, try going back to modesetting. forcing use of "intel" will cause the issue you are facing.

On the 1060 that I have here, I don't need any special tools to start nvidia-setttings, but I'm not using the "intel" driver.

That was it thanks! Unfortunately without the intel driver I get horrible screen tearing everywhere. I guess I'll stay with the intel card on Linux.

You can use the intel driver with bumblebee on MX 21 with your card, but nvidia-settings does need extra goodies on the command:

viewtopic.php?t=67997

The easiest way to test with either the MX Prime command or optirun is just compare the output of "inxi -G" alone and then preceded by the command.

Code: Select all

optirun inxi -G

I had read that thread and tried with

Code: Select all

optirun -b none nvidia-settings -c :8

but it didn't work (got the errors from the first post). bumblebee failed to activate the card.

Reposting here:

Code: Select all

$ optirun nvidia-settings
[  963.884950] [ERROR]No bridge found. Try installing primus or virtualgl.

$ optirun -b none nvidia-settings -c :8
[  986.886349] [ERROR]Cannot access secondary GPU - error: Could not enable discrete graphics card

[  986.886402] [ERROR]Aborting because fallback start is disabled.

Just adding that I switched again to modesetting and enabled

Code: Select all

backend = "glx";

in my compton.conf and I have no more screen tearing, everything seems to work well now! Thanks for the help.

This is my inxi output now:
