Fedora 34 XFCE: dual monitor hassle
by nesbit12 from LinuxQuestions.org on (#5K62F)
Hi all,
I have a relatively new PC with dual monitors that runs Fedora 34 with XFCE.
It is a Lenovo M920 ThinkCentre, with dual display port outputs. I have two monitors attached to it and it uses the on-board Intel UHD 630 graphics card.
I configured my monitors to span the desktop across both of them. After boot, this normally works fine. However, after monitors went to sleep due to inactivity, as soon as they resume the monitors randomly switch to "mirror" i.e. I have one small desktop, displayed the same on both monitors.
It is so annoying. Furthermore I don't have a XFCE panel or launchers on the 2nd monitor, so if this one gets mirrored, I have no possibility of accessing the "XFCE Display Settings" dialog to switch off mirroring!
Because I never switch off my PC, my daily ritual every morning is to switch off mirroring. Normally I put the XFCE Display Settings dialog on one monitor before I leave the PC. When I return and XFCE has decided to switch on mirroring, I can readily disable it again. This has become my daily morning routine.
The annoying thing is, that with my old PC the two monitors never went into mirror mode, but since I got this new PC it happens at least once a day.
Is it somehow possible to completely disable the mirror option? how can I find out why it switches on mirroring?
