Bug Description

I have an LG L1510SF touch screen that worked great in Karmic, OK in Lucid but not at all in Maverick...

When the USB cable to the display is connected, Xorg crashes even when I boot in recovery mode and select "failsafe X".

The lsusb output for the device looks like this:

Evtouch is going to be removed from the archive starting in natty, closing bugs that become obsolete due to that. Use the 'evdev' driver for touchscreens.
