Please attach the dmesg (with drm.debug=6 kernel command line option preferrably) and the Xorg.0.log from the failed bootup. Just started the laptop again and by chance without the power plugged in. The system works normaly and I could log in into KDE getting the expected desktop. However right after plugging in the power the screen turned black and nothing seems to work. Unplugging the power however brings back the desktop and I can work on it. So it does not seem te be related to Xorg, but to something related to the power. Do you still need the output of dmesg? Yes, I still need the dmesg and Xorg.0.log to see if that is expected behaviour for the requests being sent by userspace. Just found out that clicking on the battery icon in the system panel gives me the opportunity to disable power control. After that I can plug in the power with no ill effects. Send you the current versions of dmesg and Xorg.0.log. The one with the kernel option will be send asap. Created attachment 108892 [details]

dmesg with drm.debug=6
I updated the system between the two versions of the files to the official openSUSE 13.2 release with some additonal repositories.
I booted not on battery and now I have a black screen and unplugging the power does not help.

Xorg.0.log with drm.debug=6
Same comment as with dmesg with drm.debug=6
Still new surprises. Now I can't start up the system and get a log in screen of KDE anymore when running on battery. Experimenting with the kernel parameters that are used when booting in Rescue mode, I found that I only need "nomodeset" on the boot command line to get a log in screen for KDE. When using that the system is behaving predictable, no surprises anymore. Nothing appears wrong in the logs. Hm, might be pps fallout. Can you please retest with latest drm-intel-nightly branch from http://cgit.freedesktop.org/drm-intel That branch has a _lot_ of byt fixes.

See https://bugzilla.opensuse.org/show_bug.cgi?id=899879 Hoping this is fixed, but it looks like there hasn't been much activity on the opensuse bug either... Best bet would be to re-test with a drm-intel-nightly kernel (hopefully someone in opensuse is building those to make it easy), if the issue still occurs, please re-open. |
