Rotate console and Xorg screen

Devuan is a Debian fork.

OS: Devuan Gnu/Linux 1.0 (Debian without systemd)

Rotate console screen when the system is booted provided framebuffer is on.

Orientian of my laptop is 90 degree to right.

Add fbcon=rotate:[1|2|3] to GRUB_CMDLINE_LINUX’s option in etc/default/grub. Then update-grub.

Rotate screen in Xorg

Run xrandr -q command to find the display variable.
In my case, it is LVDS1.

Rotate screen left
$ xrandr –outupt LVDS1 –rotate left

To rotate when Xorg starts, an article suggests add the following lines in xorg.conf. I’ll test it later.

Section "Monitor"
Identifier "Monitor1"
Option "Rotate" "left"
EndSection
