Bug ID: 503532
Summary: All output changing display settings should offer and
auto back-out
Classification: Applications
Product: systemsettings
Version: 6.3.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: kcm_kscreen
Assignee: [email protected]
Reporter: [email protected]

Target Milestone: ---
Settings should be more cautious applying changes to display configuration.
Changing resolution, etc., prompts with a 15 second timeout that backs
everything out if the user didn't confirm (because they probably couldn't).
What I ran into earlier today was switching "Color accuracy" from "efficiency"
to "accuracy" (I know, serves me right), completely disabling my session
because:
kwin_core: Applying output config failed!
kwin_wayland_drm: Atomic modeset commit failed! Invalid argument
Which is probably an issue between GPU driver, GPU itself and the monitor, but
backing out of was was not easy. It would be great of the settings offered an
automatic backout on changing any options that modify the output configuration.
