Bug ID: 441343
Summary: dual monitor - cannot use extended monitor layout
after some time
Product: systemsettings
Version: 5.21.5
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: archenr...@gmail.com
Target Milestone: ---
SUMMARY
STEPS TO REPRODUCE
1. I have connected dual monitor setup, both 4k one via hdmi, secondary via
display port 1.4a
2. Botting up computer makes both screens looking as mirror even last session
before reboot wath to extend primary monitor - that is issue one, systemsetting
doesn't remember last configuration.
3. I have for example shutdown only monitors over night let PC on and when
coming back next day, I switch on both monitors, they are again mirrored, but
this time when I try to organize their layout to extended mode, I can move them
to right positions via systemsettings gui, but when click apply, its just blink
and they remain both in mirrored mode. The only thing which resolves this is PC
reboot.
I even tried to disconnect cables, etc. was playing bit with behavior, but
nothing helps. when in state of supporting only mirroring i wasn't able to get
extended view anymore.
OBSERVED RESULT
after some pc usage I cannot setup extended mode anymore without hard reboot.
