I did an upgrade from 15.0 to 15.1 last night on Intel 82945G/GZ Integrated Graphics vendor: Dell driver: i915 v: kernel bus ID: 00:02.0 chip ID: 8086:2772 (Lakeport) that works just fine (via startx, other than ignoring xrandr in /etc/xinit/xinitrc.d/05-startup which TDM does run) on Intel driver. (The 2005 945G is too old for modesetting DDX support.) -- You are receiving this mail because: You are on the CC list for the bug.

Through a quick glance, there is nothing obviously wrong in the log. Could you try to boot working Leap 15.0 kernel with drm.debug=0x0e and get the same kernel log for comparison? FWIW, I tested Leap 15.1 kernel with my CherryView laptop, and it worked fine. Though, my system is still Leap 15.0 user-space, and another chip variant (8086:22b0), so they aren't identical. BTW, what desktop environment are you testing? -- You are receiving this mail because: You are on the CC list for the bug.

This is likely the cause, indeed. Although the upstream developer claims that it should be fixed in X modesetting driver side, I find it's safer to revert the commit for now to make things working, at least. I'm building a test kernel in OBS home:tiwai:bsc1129027 repo. Could you give it a try once when the build finishes? -- You are receiving this mail because: You are on the CC list for the bug.

Even the kernel in OBS Kernel:* repos won't work with secure boot because they have no official signing key. -- You are receiving this mail because: You are on the CC list for the bug.

I pushed the fix to my SLE15-SP1 branch. It'll take some time until the fix reaches to Leap 15.1, unfortunately, because of several merge paths. Hopefully this will be handled soonish. Although this is "fixed" in the kernel side, I keep the bug open since it's basically a bug in X modesetting driver, according to the upstream bugzilla. -- You are receiving this mail because: You are on the CC list for the bug.
