qubes os 4.2.4 in kde environment. also in Wayland Does not run/launch any applications (firefox,smplayer,file manager)
my laptop is Lenovo Thinkpad E14 Gen 6
Wayland is not supported. Dont select that option - use KDE X11.
I never presume to speak for the Qubes team.
When I comment in the Forum I speak for myself.
ok i will do. but in X11 whan i put the Resolution to 3072x1920 Everything looks very good but too small to read. So I immediately tried change global scale to 150%,200% or 300% But global scale doesn’t work straight out of the box, you need to do something extra. whan i put the Resolution to 1280x800 i dont need the global scale But it looks very bad. In short, how to make the global scale work.
If your issue is related to X11 scaling you should open a new issue or modify the topic description.
There are some threads on high screen resolution but no perfect or easy solution when you are using multiple different screens.
You need to modify DPI, scale factor, GTK settings and font size. Here are some variable you can try and see if it works for you.
QT_AUTO_SCREEN_SET_FACTOR
QT_SCALE_FACTOR
QT_FONT_DPI
GDK_SCALE
GDK_DPI_SCALE
When you are using Gnome:
gsettings set org.gnome.desktop.interface text-scaling-factor
