Hi!
I'm also seeing issues, not as severe as Pete, but after I resume
(which works, with drm-next and DMC firmware), the system becomes
sluggish. It feels like I/O takes more time, and graphics are
sluggish (very sientific, I know, but for instance git operations are
much slower after a resume). I know there's been an update to acpica
between my system updates, when this started to happen, but I haven't
had time to revert that update and test again. I will try to do that
and report back.
Regards
Hi Niclas,
I used drm-next on Skylake with issues which sound similar. 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 My kernel is two weeks out of date (r333093), so I need to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.
