When I manually reduce resolution from 1920x1200
to some lower resolution in KDE (Debian 9 amd64), the command
xrandr -s 1920x1200
...does not work:
% xrandr -s 1920x1200
Size 1920x1200 not found in available modes
Well, the size 1920x1200
actually is available:
% xrandr -q
Screen 0: minimum 8 x 8, current 1920 x 1200, maximum 32767 x 32767

Setting output per answer https://superuser.com/a/1257312/200129 does not help:
when I have resolution
1920x1200
set, executing commandxrandr -s 1920x1200
flashes the screen.when I set lower resolution and add output monitor to command like
xrandr --output HDMI-0 -s 1920x1200
, nothing happens - not even screen flash.
P.S. command xrandr -s 0
sets mode 1920x1080
, which is second mode from the top.
Try to add to the
xrandr
call the parameter--output
