I think": Try September 26 as a reference date. Sometime close to then I a) updated world+kernel to the latest version of current, so also b) updated to the latest drm-current-kmod and gpu-firmware. Question: is there a way for the less sophisticated user to tell whether the cause is in the drm knod or the firmware kmod? Hope this helps, Robert Huff -- Hello ... my name is SARS-CoV-2.
