Is X11 Screen Rotation Possible?
I'm using X11 on Arch Linux.
The commands I posted are the ones I use on my script to rotate the screen.
I tested them right before I posted and they were working. Then I noticed you mentioned fbturbo - which I hadn't heard of before - so I searched for it in the repos and noticed it wasn't installed.
So I installed xf86-video-fbturbo-git and rebooted. And now xrandr gives me an error similar to yours (only difference is the "Major opcode of failed request" is 140 instead of 139, whatever that means).
As for the monitor name, mine was showing the right names, but after installing fbturbo it also listed it as "default".
Searching a bit for the error, it seems fbturbo really doesn't support xrandr rotation (https://github.com/ssvb/xf86-video-fbtur...-146012185).
It should be possible to have a fixed orientation other than the default with fbturbo, but apparently it reduces performance (https://github.com/ssvb/xf86-video-fbtur...t-45969823).
So if you can live without that driver, then it should work.
