Hey guys,
I just got me a new laptop, so now I need to limit my screen resolution.
...the new laptop has a 14" 4K display, I really don't need 3840x2160 on that little screen - FullHD should be more than enough, expecially when that means better performance in games.
I know I can switch the resolution on a per user basis in Plasma or Gnome, but how can I limit the whole thing to "only" 1920x1080? As in, even gdm/sddm runs at that resolution?
Back in the olden days I'd put that in /etc/X11/xorg.conf or somewhere like that, but nowadays that file doesn't exist and everything's autodetected...
Any suggestions?
Cheers MH
LCD displays often look/work best at their native resolutions, I think that's why scaling is often used instead of mode switching. The KDE display settings include a global scale, and fonts and icons can be scaled independently. At a more basic level there is xrandr --scale which is what I use to scale one monitor independently of another under KDE/X11. Michael
