[Solved] Xorg randomly fails to start

Since some months ago I have a problem with my laptop that happens, apparently randomly, at least 60% of the times that it's booted. I haven't still found any causes or patterns, that's why I think it's happening randomly.

The problem is that Xorg fails to start, and then the desktop manager (first kdm, now sddm) cannot be started either. When this problem began, I used to run

$ systemctl restart kdm

or

$ systemctl restart sddm

and Xorg and the desktop manager were started within a few seconds. Now the problem is more annoying because sddm takes about 90s to stop (I don't know why).

When the problem happens, this is the whole /var/log/Xorg.0.log:

I haven't been able to find any solutions to this problem, though I have tried different approaches, and I hope that some of you can give me at least some hint.

Re: [Solved] Xorg randomly fails to start

I have found an important detail that might be a clue to solve this problem.

As I said, when Xorg fails I can see these lines in /var/log/Xorg.0.log:

[     4.524] (II) [KMS] drm report modesetting isn't supported.
[     4.524] (EE) Screen 0 deleted because of no matching config section.
[     4.524] (II) UnloadModule: "radeon"

But when it doesn't fail, I see these lines instead:

[     6.568] (II) [KMS] Kernel modesetting enabled.
[     6.568] (II) RADEON(0): Creating default Display subsection in Screen section

Also, I tried this workaround, but then I get this error while booting:

[drm:radeon_init] *ERROR* No UMS support in radeon module!

Re: [Solved] Xorg randomly fails to start

That specific workaround has been useless for a long time (radeon oss driver won't work at all under X unless KMS is enabled).

It appears some times  when booting your system doesn't initialise your videocard correctly.

9] Kernel command line: BOOT_IMAGE=/vmlinuz-linux root=UUID=038deb80-5b6a-4f71-87d6-fb0344a3eeba rw quiet resume=/dev/sda2 video.use_native_backlight=0

That line sugggests you are using suspend/resume .
Does the problem happen if you perform a real cold boot ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.


(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Thanks for your answer, Lone_Wolf. AFAIK, the 'resume' parameter tells the kernel where it should look for the resume partition when resuming from suspend. Althoug suspend is enabled, I'm not really using it; the problem happens when booting from the powered off laptop (cold boot).

Re: [Solved] Xorg randomly fails to start

Ok, are you using early or late kms ( https://wiki.archlinux.org/index.php/AT … _early_KMS ) ?

Does changing that make a difference ?

Posting a full log (dmesg or journal) from a boot where you had this problem would be helpful also.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.


(A works at time B)  && (time C > time B ) ≠  (A works at time C)

Re: [Solved] Xorg randomly fails to start

That hint is interesting. I will try this change for a couple of days to see if it makes a difference. Since it happens only sometimes, I have to make several tests.

Lone_Wolf, it seems that adding radeon to the initramfs did the trick.

Thanks a lot for your help!
