Title:
Unable to put display on standby after resuming from hibernate
Status in linux package in Ubuntu:
New
Status in linux source package in Plucky:
Fix Committed
Bug description:
Hi,
I'm running Ubuntu 24.04. After a recent kernel upgrade to
6.14.0-28.28~24.04.1 I've noticed that after the system is resumed
from hibernate, the display doesn't go into standby. It goes there
briefly, but then immediately wakes up showing black screen.
In the logs I can see the following message every time this is
attempted:
[drm:parse_edid_cea_dmub.constprop.0 [amdgpu]] *ERROR* EDID CEA parser
failed
I've checked old logs, this message never appeared before. Downgrading to
6.14.0-27.27~24.04.1 appears to fix the problem.
