Public bug reported: Binary package hint: xserver-xorg-input-evdev
Using Maverick beta with all recent updates, my touchscreen (eGalax/DWAV screen found in Eee PC T101MT) doesn't work as well as in Lucid. Expected: All touches should be registered and turned into mouse movement/clicks and varying pressure on the screen should result in different opacity in GIMP and Mypaint and different line width in Xournal. What happens: Every third/fourth touch on the screen is simply ignored - neither is the mouse pointer moved nor a click registered. Pressure sensitivity doesn't work (tested in GIMP, Xournal, Mypaint): everything is drawn with the lowest pressure level, thus no lines can be drawn in GIMP. xinput shows that the pressure axis always reports a value of 1. evtest shows that the kernel sends the correct information: pressure information and all touches are reported. Manually compiling evdev (using the sources obtained by apt-get source, thus the same version Maverick uses) without the Ubuntu patches fixes both problems.
