@joekamprad and all of you:
Tried a lot on the internet found ‘solutions’ but still,
multiple monitors not working properly in Gnome.
Also can’t get the Gnome extension “multi monitors add-on” installed because “it isn’t recognised” by Gnome shell?
- monitor settings are always lost
- primair monitor becomes pixelated
- when second monitor is already connected during boot, system will freeze on two black screens
- when second monitor is connected after boot: primair monitor becomes pixelated and stays like that, second monitor will only connect when choose manual
- multiple monitors are working properly after putting settings manual and saving the settings to monitors.xml
- multiple monitors are working properly
- multiple monitors are working properly after putting settings manual and redoing that after each boot
So, now i have configured my multiple monitor settings properly in Mate and copied the monitors.xml file to Gnome. But after reboot i get the same results as under Gnome, see list of problems above.
The weird thing i noticed is that the primair monitor (laptop monitor) is shown as two monitors in the monitors (display) settings. And the second monitor is the third. ;-?
In Mate i see also two primair monitors but i have disabled one of the two primair monitors and then enabled my second monitor and in that way it works. But in Gnome that’s not possible and not working.
Thanks for help.
