Title:
Secondary monitor enters power save mode for no apparent reason
Status in Ubuntu:
New
Status in linux package in Ubuntu:
Incomplete
Bug description:
My secondary monitor has a tendency to enter power save mode for no apparent
reason while my laptop is in use; unplugging and replugging my dock from the
laptop seems to bring it back but sometimes requires a few tries. Doesn't seem
to be any of:
- after a predictable period of time
- after inactivity
Laptop: Dell XPS 13 9300, running Focal
Dock: Dell WD19TB. Recently updated; current dock version per fwupdmgr is
01.00.00.04; thunderbolt controller is 43.00; MST controller VMM5331 is 05.04.03
Monitor: Dell P2715Q
Not sure what logs would be useful, but happy to gather those as
requested.
