[opensuse-factory] Leap 15.0: problem with DRM patches
HI! On an old laptop running Tumbleweed there were crashes in DRM module making all things only working *very* slow. There have been postings here and some tickets quite a while ago but issues were never resolved. With Leap 15 until kernel 4.12.14-lp150.5 everything worked smoothly on Leap 15 and using XFCE. With the DRM patches installed with 4.12.14-lp150.6 same problems now appear in Leap 15. Can I disable this new DRM stuff with a kernel switch at boot time?

No, unfortunately. As of now, i915 drm code is essentially equivalent with the latest 4.16-rc on Leap 15.0 kernel. Depending on what went wrong, you might disable some features (e.g. fbc or such) via module options, though. But, at best, try to keep hunting the bug with upstream. Since the old Leap 15.0 kernel worked, it means a regression between 4.12 and 4.16 kernels. Please confirm that the issue is seen with the kernel in Kernel:HEAD (it should happen with that), and open a bug report on bugzilla.freedesktop.org. Feel free to put me (tiwai@suse.de) to Cc.

Try adding kernel options: |i915.modeset=0 ||nouveau.modeset=0|

For now this seems to work. Ciao, Michael.

Just for the records: It seems the better work-around is to use kernel option video=SVIDEO-1:d (removed options above) because the native display resolution 1400x1050 is usable with that. Ciao, Michael.

Hm, the latest kernel already disabled the TV output for the old chipsets, so this should be superfluous. Please check once when a newer kernel appears whether you still need that video option.
