DSI panel rotation


#1

Hello,

I plan to change my display panel by a DSI compatible one but I need to rotate 90° the output. Is this possible with the debian, where to configure this (I try to use a wayland backend, no xorg) and will it be resource consuming ?

Regards,
Nicolas

I believe weston can do rotation in gl. The display can do 180 degree rotate (hflip + vflip) but I don’t believe it can do 90, so you are better off doing it while the compositor composites the frame on the gpu

BR,
-R

I was thinking about a think like that, let doing the rotation to the gpu, but looking somewhere to do it global for entire screen. I plan to use Qt on wayland (don’t thnk weston is needed in this case for a single full screen application ?!)
