Bug ID: 502374
Summary: Defaulting to 800x600 for new monitors breaks the
steamdeck's display when changing monitor
configuration
Classification: I don't know
Product: kde
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: liarus1...@gmail.com
Target Milestone: ---
SUMMARY
When KDE detects a new monitor it defaults to 800x600, however this is a
problem for the steamdeck, when changing monitor configuration, the steamdeck's
own screen might be detected as a new screen, and be set to 800x600, which is a
resolution that results in a black screen on the steamdeck, due to it's native
resolution being 800x1280.
I encountered this issue while plugging my steamdeck in a DisplayLink hub, and
then accidentally selecting a random option in the Meta + P menu, this, broke
my steamdeck's built in display, and i had to set the resolution back to
800x1280 on the built in display to get a display output on the steamdeck.
I am not sure this could be considered a KDE Bug, as it's specific to the
steamdeck, and i assume the display would need to report it's own resolution
instead of KDE setting it to 800x600, but i thought it would be worth
reporting.
STEPS TO REPRODUCE
1. Plug an extra screen into a steamdeck compatible dock
2. Use any of the options in the meta + p options
OBSERVED RESULT
The steamdeck's own screen is set to 800x600 and thus doesn't display anything.
EXPECTED RESULT
The steamdeck screen is set to 800x1280
