Cannot Rotate FrameBuffer

[Spacefreak18]

I compiled the fbusb module, and I have connected a vocore display to my amd64 PC.

However, no matter what I try, the screen is in portrait mode. I would like to achieve a clockwise 90 degrees rotation.

more /sys/class/graphics/fb1/rotate gives a value of 0. And if i try to
echo 1 > /sys/class/graphics/fb1/rotate it doesn't take, it remains 0.

I am positive the device is attached as fb1.

Is there anyway to acheive this in hardware?

Hi, maybe you can use the new drm driver instead of old fbused driver.

In my case, with this driver, I can use the MPRO screen as a extension screen on debian bookworm (Intel integrated graphics and KDE desktop enviroument), and I can set its rotation to any direction.

You should chooise the properly repository branch according your kernel version, this branch provides the usage on Raspberry, amd64 also same.
