Bug ID: 440309
Summary: Request: add functionality to test diplay settings
before applying them
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: david.cortes.riv...@gmail.com
Target Milestone: ---
Would be helpful if the "Display Settings" section (the one where one can
configure screen resolution and related stuff) would have a button to test the
changes before applying them, in the same way as e.g. MS windows - that is, one
sets a new display setting (e.g. testing a different screen and resolution),
clicks "test", it changes to the new settings for 5 seconds or so, and then
comes back to the old setting.
This would be especially helpful in settings in which some change could result
in an invalid display that does not allow visual cues to revert - for example,
in my own setup, if I try to switch to a laptop screen after another screen is
already running on HDMI, it shows only random noise on the screen, so I cannot
click back on 'reset' to change the settings (this is a mesa bug so unrelated).
