What else will make the previously working mode now invalid. The crash is going to be some mistake in error handling, but we're not going to get much without debug symbols. Is there any chance you can compile with --enable-debug=full? That should have the added benefit of capturing why the kernel rejected the mode as well. (In reply to nico-freedesktop.org from comment #4) > Plus the actual driver (why do we still have xf86 in the name? ...) History + inertia. There is actually a good reason to have lost the link: I disconnected the external usb-c adapter while sleeping and took the notebook for a trip. Regarding debug compile: which part (full xorg, xf86-intel only?) should be compiled with debug symbols?

Ah, useful to know. Should just be a case of debugging the error handling... > Regarding debug compile: which part (full xorg, xf86-intel only?) should be > compiled with debug symbols? For the time being, we just need debug symbols for -intel. Created attachment 133179 [details]
xorg.log from crash with debugging
Added output of crash with debugging enabled.
Note: it took me 3-4 times to put the device into sleep *and* a change to a different console to provoke the segfault.
Prior to changing to a different console, the screen would just stay black.
Attention: the logfile is 185 MB big.
