Bug ID: 511916
Summary: Plasma doesn't recognize proper resolution (and
device?) after monitor is back after being turned off
due to power saving settings
Classification: Plasma
Product: plasmashell
Version First master
Reported In:
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Target Milestone: 1.0
SUMMARY
When the monitor turns on after being turned off due to power saving settings
(Settings > Power Management under the "Display and Brightness" section),
Plasma shows a notification about the display being disconnected. The maximum
supported resolution in settings is then set to 640x480, with the message: "640
x 480 (4:3)" is the only resolution supported by this display. To fix this, you
have to turn the monitor off and on again, after which a notification about a
new display being connected pops up.
STEPS TO REPRODUCE:
1. Wait until the monitor is turned off automatically
2. Move your mouse or press any key to turn the monitor back on
3. Observe the incorrect resolution
OBSERVED RESULT
Plasma sets an incorrect resolution after the monitor is turned on again.
EXPECTED RESULT
Plasma should restore the proper resolution after the monitor is turned on
again
