[SOLVED] Xorg not starting with kernel 6.9

martinbaselier · 2024-07-06 12:47:54

I have a i915 and when I update the kernel to 6.9 Xorg won't start. Currently it's 6.9.7 but it's with all versions of 6.9
I have 2 videocards and I use to onboard card for Linux and for my VM I use a 1080Ti.
This is my Xorg.conf to select the intel driver:

Section "OutputClass"
        Identifier "intel"
        MatchDriver "i915"
        Driver "intel"
        Option "PrimaryGPU" "yes"
EndSection

Section "Device"
  Identifier  "Intel Graphics"
  Driver      "intel"
  Option      "DRI"  "iris"
  Option      "TearFree"        "false"
  Option      "TripleBuffer"    "false"

  Option      "SwapbuffersWait" "false"
EndSection

If I turn that config off X starts, but it's totally unusable. It looks like it's using my 1080 (since it's using all 3 of my monitors and one is only attached to the 1080) but without a proper driver, since I removed all nvida-related stuff and blacklisted nouveau. X is using 100% cpu and I need to force X to close. I've also tried removing the options and only choosing the intel driver, but that makes no difference.

These are the errors in the log of Xorg when X doesn't start.

This are my kernel options:

This is everything related to the i915 in journalctl when booting kernel 9.5:

This is the same as normal, except on 6.8.8 it also shows i915 display info.

I've read somewhere kms should be enabled, so I enabled it. Thuis is my mkinitcpio.conf:

MODULES=(i915)
BINARIES=()
FILES=()
HOOKS=(base udev autodetect modconf kms keyboard keymap block filesystems fsck)

This are the videocards I have and my CPU is a Intel(R) Core(TM) i7-7700K CPU @ 4.20GHz.

I understand there has been a major change in the kernel, specifically on the video-part. If someone could give a suggestion on where to look, I'd be happy.

Remove your config as well as xf86-video-intel and retest. xf86-video-intel should generally not be necessary and is not going to be well tested on newer iGPUs

That gives a slightly worse result. X still uses my 1080 and not my i915. I only have one monitor for use, no start menu, no panels (xfce4) and I can hear my CPU fan spinning up to maximum speed. That's an indication of high cpu usage. Also there's no display when I quite X. I could still type and reboot.
I started using a conf-file for xorg again in 2022, since X kept using my 1080, even if I blocked all kernel-modules.
Also my cpu is of the 7th generation. Which isn't quite new.

Thank you @V1del for pointing me in the right direction. I created a new config for X and now I can use the modesetting driver on my intel-card and get rid of x86-video-intel and use the new kernel. Hopefully this will also solve some weird other display-stuff which I couldn't find a solution for.
