Ok, i think i know why the touchscreen input isn't working right. I used
a startscript which changes the screen resolution and orientation before
and after i start doom. But now i tried to do it in single steps and i
found a behaviour which is not right.
When i change the screen to 320x240 landscape mode the touchscreen input
seems to be still on 640x480. Because on the desktop i can see that the
mouse is moving only for 1/4 of the touchscreen area within the visible
screen resolution.

I use these two commands to change the display resolution and orientation:
echo qvga-normal > /sys/bus/spi/devices/spi2.0/state
xrandr -s 240x320 -o 1

Is there anything which i can do so that the touchscreen input also is
scaled to 320x240 in landscape mode?
