Hello Alex and Rex, I've found good hint from Jan (randomsalad) on phoronix for the 'screen blank' (monitor standby mode): https://www.phoronix.com/forums/forum/phoronix/latest-phoronix-articles/984483-amdgpu-dc-gets-a-final-batch-of-changes-before-linux-4-15?p=984555#post984555 My Reply: https://www.phoronix.com/forums/forum/phoronix/latest-phoronix-articles/984483-amdgpu-dc-gets-a-final-batch-of-changes-before-linux-4-15?p=984581#post984581 I can swear, that I could 'return' one time (the first time, maybe due to only warm reboot) on 'drm-next-4.15-dc-wip' directly from within KDE session with replugging the video cable, but for all later tests on both kernels I have to blindly switching back to login screen (kdm_greet) and then replugging the video cable. For me these regression started with 'amd-staging-drm-next' much earlier than with the latest commit. Dieter
