Red Hat Bugzilla – Bug 596642
Confusing Error Messages Displayed When Switching Displays
Last modified: 2017-12-06 07:59:56 EST
Description of problem:
This only small usability issue, please feel free to handle this as you like.
When connecting an external display to a laptop and hitting the display switch key everything works as expected but GNOME display one (or two, varies) confusing notification windows which say something incomprehensible for a random user:
Could not switch the monitor configuration
could not set configuration for CRTC 143
When hitting the display switch key again, this message is not displayed. It seems be displayed only for the first time after an external display is connected or disconnected. All the time all displays work all ok.
I'll attach dmesg/X/sys logs from one system showing this but my untrained eye couldn't see anything there and this also happens on some other models (and other display drivers).
