X freeze after touch with touchscreen

[Benjamin Meeusen]

Binary package hint: xorg

I have a touchscreen connected through usb. X freezes a lot after touching the screen. The touch itself is not registered or at least not visible that I have touched the screen (e.g. if I click a button, the button is not highlighted).
The frequency varies from a couple minutes to an hour after boot.
I can ssh into the system. I have collected several intel batchbuffer dumps as explained on http://wiki.ubuntu.com/X/Troubleshooting/Freeze, each time turning off a different option in xorg.conf. The one attached is without any options in xorg.conf, except for the DebugFlushCaches option and with the default evtouch package installed.

I don't have this problem when I install Ubuntu 8.10. With 9.04, I experience the same freezes.

This issue was reported against karmic, so can you confirm if this issue exists with the most recent Lucid Lynx 10.04 Alpha release? ISO CD images are available at http://cdimage.ubuntu.com/releases/lucid/ . Thanks in advance.

I have installed Lucid Lynx alpha 2 release, but I need to found i way to make my touchscreen work. With previous ubuntu releases, I installed xserver-xorg-input-evtouch and used a fdi policy file for hal, without any modification to xorg.conf.
Now, out of the box, without evtouch installed, the cursor moves to the upper left corner at every touch. As soon as I find a way to calibrate my touchscreen, I can test for freezes.

[Benjamin Meeusen (ravenous)]

I have tried to get my touchscreen working in Lucid, but I haven't succeeded. With alpha 2, when I do 'cat /dev/input/eventX', I get normal output with every touch or movement on my touchscreen, but after updating (and in alpha 3), my touchscreen device is sometimes not listed anymore in 'xinput list' and 'cat /dev/input/eventX' does not output all movement/touches.

I have tried evtouch driver with egalax few weeks ago and it was not working. The most efficient way is to install the egalax driver from here
http://home.eeti.com.tw/web20/drivers/touch_driver/Linux/20100120/eGalaxTouch-3.00.3719-32b-k26.tar.gz

follow the instructions in the guide. the calibration utility is provided (TKCal) and also a Touchpanel setup utility.
