Bug ID: 412317
Summary: Disconnecting HDMI Cable does not remove secondary
display
Product: systemsettings
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY:
When running an external monitor via HDMI, the monitor is automatically
detected and shows the dialog to choose Unified Outputs, Extended etc. Upon
removing the HDMI Connection, the external monitor is still enabled under
Display Settings, and has to be manually disabled. There is no dialog of
confirmation that the HDMI cable has been removed either
STEPS TO REPRODUCE
1. Connect an external monitor to your laptop (which has display of eDP-1)
2. Secondary monitor is shown under 'Display Settings'. Remove the HDMI Cable
without disabling the display
OBSERVED RESULT:
- Nothing shows on screen, and the display stays connected. Windows continue to
open off screen, and move off screen when moved to the top of the screen.
EXPECTED RESULT
- External display is disabled, and only the eDP-1 display is left enable
