Product: plasmashell
Version: 6.3.2
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: crash
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org

SUMMARY
Triple head displays are blank on login screen and desktop. Used to work
before updates. No hardware changes. Unplugging and plugging back in displays
causes them to work again for that session.
STEPS TO REPRODUCE
1. Boot PC See boot logo on all three displays
2. Login Screen Black except for static cursor in top left. Unplug display,
the other two come on, plug back in, all three on. Log in.
3. All three black again, repeat unplug display, the other two come on, plug
back in, all three on.
OBSERVED RESULT
The displays are blank. They are on and displaying only black. Unplugging one
display, doesn't matter which one, will cause the other two to show the login
screen or desktop depending on step. Plugging that display back in all three
displays show the login screen or desktop.
EXPECTED RESULT
All three displays show the login screen or desktop like they did before.
