Devuan is a Debian fork.

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

I bought it as used one years ago.
Add fbcon=rotate:[1|2|3] to GRUB_CMDLINE_LINUX’s option in etc/default/grub. Then update-grub.
# If you change this file, run 'update-grub' afterwards to update

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
