I have 2 monitors connected, otherwise they work fine except when I want to keep my secondary monitor turned off in between. My annoyance is when the screen appears in the settings with the number 1 and thus the login screen also comes into it. My system is Manjaro gnome 21. something and gnome 40.3.0 … Monitors again VGA (Toshiba Matsuhita display 22 “) and DVI (Hewlet Packard 20”) and video card radeon HD 4340 (to remember :)). If that screen is off, then the login window will not appear :(. However, if I have 1 screen specified in the settings and I use that screen on and I turn on the machine then the screen will kind of turn off when the login is complete. linux mint also has that opportunity … Is that an opportunity in Manjaro?
