Xorg errors with notebook dedicated/builtin graphics

dm-on · 4 January 2021 23:34

Hi! I am trying to understand some Xorg issues after going through the rouble of fixing drivers after a failed update.

I am using Kernel Manjaro 20.2 with Kernel 5.9 (got some old Kernels still in the system as well) and used

sudo pacman -S mhwd-db
sudo mhwd -a pci nonfree 0300

to install drivers. It got me

$ mhwd -li

! Note that in the live-boot of 20.2 with Kernel 5.9, choosing non-free drivers, I get video-hybrid-intel-nvidia-455xx-prime instead!

Anyways, trying to start my Xfce4 desktop, I always got stuck loading Xorg. var/log/Xorg.0.log included various errors, e.g.

...
(EE) Failed to load module "intel" (module does not exist, 0)
(EE) Failed to load module "nouveau" (module does not exist, 0)
(EE) Failed to load module "nv" (module does not exist, 0)
(EE) Failed to load module "fbdev" (module does not exist, 0)
(EE) Failed to load module "vesa" (module does not exist, 0)
...

I had similar although less Xorg errors when trying to use free drivers instead (uninstalling the previous one and using sudo mhwd -a pci nonfree 0300). I also tried video-hybrid-intel-nvidia-390xx-bumblebee and it didn’t work (didn’t check Xorg logs though)

The way I got this to work in the end was by disabling the onboard Intel graphic chip in my bios. Xorg starts without complaints then and I got back into the system.
Driver performance is pretty bad now, nowhere before my system crash and I had to diable the Intel chip

It raies the questions:

Why am I not getting video-hybrid-intel-nvidia-455xx-prime (as in the live-boot) but instead the video-hybrid-intel-nvidia-390xx-bumblebee and video-hybrid-intel-nvidia-prime recommeneded by mhwd?
Why is Xorg having these errors? Is there anything I’ve got to do after installing the drivers? Run some script to update Xorg startup perhaps?

Thank you for any insights

Do I assume correctly that mhwd will be generating the Xorg config file as described here? I’ve got /etc/X11/xorg.conf.d/90-mhwd.conf and it says it was generated by mhwd, but it’s empty (just a comment). But does mhwd also correctly call nvidia-xconfig? Because that file looks nothing like the file nvidia-xconfig generates

There were changes regarding the state of NVIDIA drivers. video-hybrid-intel-nvidia-prime is what you want, it always refers to the latest driver version.

The errors you posted do not seem to be relevant. Those modules are not really required for your configuration. You shouldn’t need to do anything for it to work.

Please post the output of inxi -Fazy, and look for other warnings/errors in the Xorg logs.

@pobrn I just rebooted with the Intel onboard graphic activated in my BIOS again.

Does any of this make more sense?

Seems like glamore-egl is the issue here as it’s the last module attempted to be loaded and the stacktrace says (EE) 21: /usr/lib/xorg/modules/libglamoregl.so (glamor_egl_init+0x53).

The xorg-server 1.20.10-3 package says that it replaces and conflicts with glamor-egl, not sure what that means.

It says on modesetting(4) — Arch manual pages that the modesetting driver (which is auto-installed by Manjaro to support the Intel card) is using Glamor for acceleration. I could probably try to change my Xorg config to include AccelMethod "none" for the Intel card but not having acceleration wouldn’t be great either, performance is pretty poor with the Nvidia driver actually, nowhere to what I had before this whole debacle.

I suggest you look around and see if you can see any similar issues in the bug tracker; and/or install xorg-server-git and mesa-git from the AUR (note, there is a mesa-git package in the community repository, that is not what I am referring to) without stripping and with debug symbols (you need to modify /etc/makepkg.conf), and thus a more complete stack trace may be recovered, which could shed some light on the issue. Or you could simply reinstall the system/restore a backup… which is not optimal, but is probably a solution.
