[SOLVED] nvidia driver ok, but intel-mesa selected for glx

fsauer · 12-17-2023, 12:05 PM

Hi all,
I'm currently baffled by a new behavior of my slackware current. Unfortunately, I cannot resolve during which update or removal of "unneeded" files I broke smthg.

I have been playing via steam and wine without any problems, having a GeForce card in parallel with an on-board intel (unused).

Now, the nvidia driver is installed without hitches, during X startup the nvidia driver is loaded, all looks nice. But glxinfo gives me the intel_mesa.

Please, kindly point me to any things I might have overlooked.

Thank you!
Franz

From your Xorg attachment it seems that the NVIDIA driver is indeed being loaded, and it recognizes your NVIDIA GeForce GTX 1060 GPU. However, it also indicates that the Indirect GLX is disabled, and AIGLX is loaded and initialized with the "iris" driver.It's possible that AIGLX is interfering with the direct use of the NVIDIA GLX. AIGLX is an extension for X.Org that enables advanced features like compositing. However, in some cases, it may cause conflicts with the NVIDIA driver.

I think you should disable AIGLX.
maybe edit xorg.conf and add the following line to the "Device" section for the NVIDIA GPU

Code:

Option "AIGLX" "off"

if you dont have xorg.conf probably you should create one something like this

Code:

Section "Module"
    Load "modesetting"
EndSection

Section "Device"
    Identifier "NVIDIA"
    Driver "nvidia"
    Option "AllowEmptyInitialConfiguration"
EndSection

Thank you rizitis! You saved my day. All is well now....
