Configuration Issue.
Classification: Plasma
Product: KScreen
Version: 5.26.90

STEPS TO REPRODUCE
1. Have Multiple Nvida GPU's 970 and 3070
2. Have 6+ monitors
3. Configure layout for multiple monitors.
4. Set kernel parameters for Nvida GPU
5. Observed in Wayland and X
6. Tried configuration on 5.26.5 and 5.26.90
OBSERVED RESULT
2 Monitors connected 2 2nd GPU(970) have issues. Once configuration is finally
set on reboot it is lost. Next getting it back is a tiresome process. I have to
enable and disable the 2 monitors back and forth and can finally get them to
work. Sometimes they show as enabled but the screen is blank.
EXPECTED RESULT
All monitors work with both GPU's and the configuration is preserved on reboot.
SOFTWARE/OS VERSIONS
Windows:
macOS:
Linux/KDE Plasma:
(available in About System)
KDE Plasma Version: 5.26.90 or 5.26.5
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
ADDITIONAL INFORMATION
The Display Configuration setup now with this many monitors and them mostly all
being the same model make it extremely difficult to identify the one you want
to make primary. In the display configuration the monitor ID is not displayed.
So when I hit identify I can't easily find what that relates to in the
configuration. I have to disable each monitor and enable them one at a time to
find out which is which. So not so much related to this bug but would be nice
to make identifying monitors much easier as a side to this bug.
