How to rotate screen in Ubuntu using terminal?
You should use xrandr
command.
xrandr -o normal
takes your screen back to normal (landscape) rotation.
You can check this command typing xrandr -o left
and then get back to normal.
You can use these commands:
xrandr --output $(xrandr |grep eDP|cut -d" " -f1) --rotate left
xrandr --output $(xrandr |grep eDP|cut -d" " -f1) --rotate normal
also right
and inverted
I created a script here: https://gist.github.com/rubo77/d43cc5b3ff65d6df28b8b8c3c089f23b
with that script, you can simply call
rotatescreen.sh -r
rotatescreen.sh -l
rotatescreen.sh -i
rotatescreen.sh -n
Alternative, you can use CTRL+F8 to rotate using
gsettings set org.gnome.mutter.keybindings rotate-monitor "['XF86RotateWindows', '<Control>F8']"
