Title:
[KDE] On resuming from sleep the external monitor is activated alone,
and the laptop screen stays completely black
Status in kwin package in Ubuntu:
Incomplete
Status in xorg-server package in Ubuntu:
Incomplete
Bug description:
Hello,
I'm using a thinkpad as a workstation, with a dual-display configuration: the
laptop screen and a big external screen.
The screen is directly connected to the laptop hdmi port, because using it
through the thunderbolt port is hit-and-miss, but this is another story.
When I wake my system on after a night sleep, more often than not -
it's not systematic -, my primary screen - the bigger external Dell
monitor - is activated alone, and the laptop screen stays completely
black.
I have to go to system settings -> Display to activate it again.
thanks for your support
/Bruno Hivert
