Xorg crashed with SIGABRT in raise() [drm] failed to set drm interface version.

[Daniel Winzen]

After starting Ubuntu, a Message showed up, that I'm running in low graphics mode. In the console I realized that the /etc/X11/xorg.conf file was deleted, so I copied a backup and after restarting Ubuntu this Apport-bug came up.

[ 39.722] (EE) RADEON(0): [drm] failed to set drm interface version.

[ 39.722] (II) UnloadModule: "radeon"

[Bryce Harrington (bryce)]

From the core, the X server is terminating due to lack of the drm driver:

No locals.

From Xorg.0.log, X is started at [ 38.095] sec.

But from dmesg, it indicates drm is not initialized until 38.165:
[ 38.165478] [drm] Initialized radeon 2.29.0 20080528 for 0000:02:00.0 on minor 0

Then X fails due to not being able to see the drm it expects:

[ 39.722] (EE) RADEON(0): [drm] failed to set drm interface version.
[ 39.722] (EE) RADEON(0): Kernel modesetting setup failed
[ 39.722] (II) UnloadModule: "radeon"
[ 39.722] (EE) Screen(s) found, but none have a usable configuration.
[ 39.722]
Fatal server error:
[ 39.722] no screens found
[ 39.722] (EE)

I think this is another dupe of:
https://bugs.launchpad.net/ubuntu/+source/libdrm/+bug/982889

[Bryce Harrington (bryce)]

@Daniel, can you see if the workarounds I posted to bug #982889 work here too? If they do, that probably verifies this is indeed the same issue.

[Daniel Winzen (q-d-deactivatedaccount)]

I realized that the /etc/X11/xorg.conf file was deleted, so I just copied a backup and after restarting Ubuntu everything was working, but I tried restarting it before coping the config file, but this didn't work. I don't know why the xorg.conf was deleted, but after restoring it, it worked like a charm.

[Bryce Harrington (bryce)]

Perhaps xserver reading xorg.conf adds just enough delay to resolve the race condition. So my bet is that what's in your xorg.conf doesn't actually matter. Try putting a 1 sec sleep into your lightdm config as described in the above bug and remove your xorg.conf, and I bet it'll work then too.

[Daniel Winzen (q-d-deactivatedaccount)]

Yes, deleting the xorg.conf file and adding sleep 10 to the /etc/init/lightdm.conf can also be used as a workaround.

[Bryce Harrington (bryce)]

Thanks, so that confirms it is the same issue.
