Title:
Weird behaviour of touchscreen and system freezes after using xinput
Status in “xorg-server” package in Ubuntu:
Expired
Bug description:
I have an Acer T231H touchscreen monitor connected to my notebook. To make
the touchscreen work properly I always used this command: xinput set-prop 'Acer
T231H' 'Coordinate Transformation Matrix' 0.545454 0 0 0 1 0 0 0 1
This should configure the touchscreen to be mapped only to my external screen.
But since the update to Ubuntu 12.04 LTS (fresh install) I get the following
errors after issuing the command:
* The mouse jumps left and right between two points when I try to use the
touchscreen. (Even though one of the points is at the right location)
* The whole desktop freezes after a few seconds of "using" the touchscreen.
("sudo /etc/init.d/lightdm restart" recovers the system)
Do you need any additional information?
EDIT:
The problem also occurs when I use this command to map my touchscreen: xinput
map-to-crtc 'Acer T231H' HDMI1
Just some more information on the behaviour of the system after the command:
* You can still move the mouse.
* If you used map-to-crtc, the touchscreen works correctly now.
* But the system doesn't react to any clicks.
* Music keeps playing. (So the system itself isn't dead)
* You can use Ctrl+Alt+F1 to switch to a terminal.
