Ok, so might be two issues, of which one is solved with the patch. > Only when e.g. shutting down does plymouth manage to display things > again, or when restarting the display manager (lightdm, which uses X11) > via ssh from another machine manages to restart the display. These ways > of getting the screen back are the same as before the patch. Ok. Now two more questions: I assume the 6.0.12-1 which should now be in testing as well does not solve the problem as well? And in case not, would you be able to do a bisect of the the changes between 6.0.8 upstream (included with 6.0.8-1 upload with ABI 4) and 6.0.10 (included with 6.0.10-1 and ABI 5)? https://wiki.debian.org/DebianKernel/GitBisect There were a vew i915 related changes between the two versions in stable upstream.
