I am unable to set my screen rotation to portrait, can anybody tell me how to do this ? It is even a problem when I turn on the computer.
In the menu with Settings → ARandR you can set the orientation of your desktop.
The configuration can be saved via its menu to ~/.screenlayout/default.sh
Content of my config :
#!/bin/sh
xrandr --output DisplayPort-0 --off --output DisplayPort-1 --off --output DisplayPort-2 --off --output DisplayPort-3 --mode 1920x1200 --pos 0x0 --rotate left
Now BIOS and BOOT I don’t see how to rotate. The login screen I can live with that until I know the system better.
Would you consider sharing your desktop when succesful?
