Display rotation with official armbian image

[g5pw]

Hello,
We recently acquired a T2-OLinuxIno-LIME2 board with a LCD-7-CTS display, we are encountering some issues rotating the display 90 degrees with the olimex buster image.

We use the armsoc driver and apparently rotation via `xrandr` is not supported:

Code Select Expand

root@olinuxino:~# xrandr --output None-1 --rotate left
xrandr: output None-1 cannot use rotation "left" reflection "none"

Putting

Code Select Expand

Option "rotate" "cw"

in the Device section of /etc/X11/xorg.conf.d/80-armsoc-sun4i.conf does nothing, and putting

Code Select Expand

Option "Rotate" "left"
in the Monitor section of /etc/X11/xorg.conf.d/01-armbian-defaults.conf makes the armsoc driver crash.

I've looked around this forum and most of the posts indicate using fbturbo as driver, is that still valid?

Try to write

Code Select Expand

extraargs=fbcon=rotate_all:1
in

Code Select Expand

/boot/ArmbianEnv.txt
This suggestion is based on this:

Thanks for the suggestion, LubOlimex! The solution you proposed does not work, but you pointed me in the right direction: adding

Code Select Expand

extraargs=fbcon=rotate:1

does indeed rotate the console, but not X.

I made it work by not using armsoc as driver but the plain fbcon with

Code Select Expand

Option "Rotate" "CW" in the Device section of my Xorg config. I will be testing how it performs in the following days.
