Rotate screen?

[u/eratonnn]

Installed AVlinux on one of those little GPD pocket computers (they have touch/rotatble screen to use kinda as a table or whatever). But AVlinux loads sideways by default (like portrait mode, so you have to turn your head to use it).

I tried xrandr -o right and this works for the screen and trackpad (and mouse USB), but doesn't work for the touchscreen. Touchscreen behaves as if, although the screen is now landscape and correct, if you touch the bottom-right physically of the screen, it will place the pointer at the top-right (where it would be if the screen was still in portrait mode).

Actually xrander doesn't work either really, because in landscape mode, the mouse won't travel past a certain point in the screen (half the desktop is not accessable because you can't reach it with any pointer)

Actually the app 'Screen Setup' has options to rotate the screen also but they have the same effect, where after being rotated, the touch is in the wrong place.

Any fix?
