[Solved] xf86-video-intel: No devices detected

Hi,

I recently rebooted my system to update from kernel 3.6.9 to kernel 3.6.10. Usually I only reboot for kernel updates, so it is kinda hard to say which update caused it but after I booted, the X server does not start anymore, it fails with this Xorg.0.log file:

https://gist.github.com/4296940

I tried downgrading to Linux 3.6.9 (known to work with this) which didn't help, I tried downgrading to the previous xorg-xserver, I tried downgrading xf86-video-intel to 2.20.13, 2.20.14 which did not help either. There seems to be *something* that prevents the Intel driver from seing my video card. Anybody knows what I can do? It does not seem like this issue is common in the Arch forums, because I googled and did not come across any issues.

I have a ThinkPad T420 with the SandyBridge GPU, so about as Linux compatible as it can get.

I would greatly appreciate if someone could at least pinpoint the issue. Like this my main computer is kinda useless. I tried booting Fedora 17 to exclude hardware defects and Fedora runs X11 just fine.

regards,
Leonidas

Re: [Solved] xf86-video-intel: No devices detected

Could you post the output of ls -l  /etc/X11/*   ??

Hi,

Thanks for your answer, here it is: https://gist.github.com/4306072#file-etc_x11, along with the contents of all files that are inside /etc/X11.

What happens if you install the vesa drivers? Does it actually find devices then?

It seems familiar to my problem here https://bbs.archlinux.org/viewtopic.php?id=154630 except that I already have vesa drivers, modesetting and fbdev installed.

If I force my system to use the intel driver I get "No devices detected" as well.

Alright, I figured it out: it was because for some reason plymouth did not terminate and blocked the GPU. After I killed plymouthd, GDM started just fine.

Seems to be the reason here too! Thanks!

I haven't tried the git PKGBUILD on AUR though. I should probably try that sometime.

Done.

I used the plymouth-git PKGBUILD and it didn't work for me. If it failed for you with the regular plymought PKGBUILD, then I don't need to try it anymore.
