Bug ID: 361750
Summary: Multi-Screen configuration lost
Product: plasmashell
Version: 5.6.2
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: Multi-screen support
Assignee: aleix...@kde.org
Reporter: rip...@freakmail.de
CC: plasma-b...@kde.org
After powering off and on one monitor, the configuration is completely broken
Reproducible: Always
Steps to Reproduce:
1. Set-up a Multi-Monitor environment: 2 screens (1xHDMI / 1xDVI->HDMI,
monitors next to each other)
2. Turn off the left monitor
3. Turn the left monitor back on again
Actual Results:
The off/on Monitor does not regain it's setup
Expected Results:
The Multi-Monitor setup should not change in any way.
If it is possible (which I don't know) I'd prefer that there'd be no change at
all just because a monitor powers off - only change something if a monitor
physically gets disconnected, though I'm afraid that this is probably
impossible to distinguish.
At least there should not be any change if monitors are powered of by
Powerdevil or other system-energy-saving tools (I believe that this happened to
me before, but I'm not 100% sure).
This is most likely related to https://bugs.kde.org/show_bug.cgi?id=356225 but
I'm not on a Laptop and I'm not physically unplugging a monitor (i.e. pulling a
cable) but simply powering off/on.
xrandr -q is identical after powering off/on one of the monitors (so xrandr
actually get's it right) - could it be some timing issue / race condition?
Additionally, after going to systemsettings and deactivating / re-activating
the "broken" monitor, I sometimes do not get my panels back on the original
spot.
I'm attaching some files in the next comment(s) (it's not possible to make
attachments in the original report, is it?)
