View Full Version : [ubuntu] How do I calibrate the touchscreen?

June 27th, 2008, 10:36 PM
I put 8.04 on my Vaio UX280p, and the touchscreen responds to touch, but in the wrong place. I want to calibrate it so it works right.

Also, I want to disable the tap-to-click behavior of the mousepad, at least for when I try to move the mouse (right now, whenever I try to move the pointer with it, it clicks first so I always end up dragging things). By the way, the mousepad I speak of is the little knob-like finger-mouse, the same as that included with old IBM's.

Thanks a bunch!

hi there,
the following might help:

Backup /etc/X11/xorg.conf (sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig)
then add this to your touchscreen input section:
Option "Calibrate" "1"

then install the evtouch drivers if they are not already installed

sudo apt-get install xserver-xorg-input-evtouch

then run sudo /usr/lib/xf86-input-evtouch/calibrate.sh.

Restart X and see if it helps... if not, more xorg.conf tweaking may need to be done.

You may want to try Intrepid as it comes with new supprot for many touchscreens and calibration utilities.
