Interesting, can you also please attach Xorg.0.log and xrandr output. Please tell me this a kernel regression... :) (In reply to comment #4) > Interesting, can you also please attach Xorg.0.log and xrandr output.

Xorg.0.log
The last change in the Xorg.0.log is: [ 525.169] (II) intel(0): resizing framebuffer to 3840x1200 [ 525.169] (II) intel(0): switch to mode 1920x1200 on pipe 0 using HDMI3 [ 525.196] (II) intel(0): switch to mode 1920x1200 on pipe 1 using DP2 [ 525.212] (II) intel(0): switch to mode 1920x1200 on pipe 0 using HDMI3 but xrandr still believes that the current fb is 1920 x 1200 with the two outputs in clone mode. Prior to that modeset, the two outputs were indeed mirrored (with a 1920x1200 fb). Can you please confirm that the xrandr is from after 525s? dmesg also believes that the two pipes should be in an extended configuration.

Hmm, here I attach a new dmesg and Xorg.0.log which after system boots I just start X and gnome, then do rotation. Maybe these info is a little more clear :) Created attachment 83346 [details]
system dmesg fae5cb
Created attachment 83347 [details]
just rotation
I don't think this is a kernel/Xorg bug. The modesetting sequences and hardware programming look valid, and that is confirmed by the scrot pricture. I think gnome-shell is misrendering. Closing old verified. |
