Resuming from suspend, or simply switching the laptop display output off and on from xrandr, resulted in graphics sluggishness (drop to 30fps in glxgears) and graphical corruption in Xorg apps, which persisted even after restarting these apps. Switching to drm-stable made the problems go away; I haven't had time to figure out what -next is doing differently to cause them. Pete's issue sounds more severe, and unrelated as it happens without drm loaded. My kernel is two weeks out of date (r333093), so I need to check whether the more recent changes affect my system as well. TheronReceived on Sun May 13 2018 - 13:58:14 UTC
