Liliput 8" touchscreen XY flip

bobtheduck32 · 04-13-2008, 04:34 PM

I have installed LinuxICE on a computer with an attached an 8" touch screen. It appears as though the touch screen drivers are working as the touch screen does respond. However, the X and Y axis are switched. As motion occurs across the screen in the X direction, the cursor moves in the Y direction. I have also installed Gentoo and Ubuntu successfully and installed the e-galax drivers. They also give the same result. Has anyone else run into this issue? Any help would be appreciated. Thanks!

providing you've run the calibrator (icetouch) under LinuxICE and you still have a swapped X and Y axis, you can add the following to xorg.conf evtouch device options:

Code:

option 'rotate' 'ccw'

This will rotate the screen counter-clockwise and un-swap the X and Y.

Hope this helps.

BTW, if you've been able to get evtouch working in gentoo, could you mind giving kantlivelong a hand. He can't get the touchscreen to work at-all using gentoo (http://www.mp3car.com/vbulletin/linu...00-gentoo.html).

I just managed to get that line added to my xorg.conf file and it's working now. The calibrator application didn't quite set the max and min's properly. I had to manually set those and play around a bit until it cooperated. I am having a bit of another problem though. It seems to assume that I always want to double click when I press on the screen and single click when I hold down for more than half a second. Is there any way I can reverse those, or at least turn off the double click? Thanks again!

can you post your xorg.conf? It'll help me not to make irrelevant suggestions if I can see what you have in there currently.

thanks

change your mouse line to /dev/input/mouse0 instead of mice. That should help there.
