Description: This patch fixes mouse and touchscreen issues of the KDrive Xserver when rotating
the display.This patche is againsy xorg-xserver 1.4 source, however, as of Dec. 22 2007 the GIT
should also be patchable.
Description: This patch fixes mouse and touchscreen issues of the KDrive Xserver when
rotating the display. Additionally it introduces the option to use long touching the display
to generate Button 3 (right mouse button) events. This is for tslib driver usage!
To enable longtouch, add longtouch=<TIME> to the tslib driver options on
the Kdrive server. <TIME> is in milliseconds and specifies how long a touch needs to last
ButtonDown 3 event is generated. If touching the screen is released earlier, ButtonDown 1, followed
by ButtonUp 1 events are generated, hence a Button 1 Click event is generated. The default
longtouch is zero, which means, without explicitly specifying this option on start up,
long touch is disabled -> old touchscreen behaviour
Additionally you can speficiy option tolerance=<PIXEL>. Inside a box of <PIXEL>
screen pixels) around the
touch position, any stylus movement will be ignored till long touch timeout is reached or touch
ends. If moving outside this box, the long touch timer will be stopped and ButtonDown 1 event
generated, thus implementing left mouse button dragging. The default value for
tolerance is 5 screen pixels.
Xfbdev -mouse mouse,2,device=/dev/input/mouse1 -mouse tslib,3,device=/dev/input/touchscreen,longtouch=500,tolerance=3
This starts KDrive with a possible mouse on /dev/input/mouse1 and utilizing touchscreen device
/dev/input/touchscreen, whereas a ButtonDown3 mouse event is generated after 1/2 second and
movements beyond 3 pixels from touch position will cancel Button 3 timer, switching to Button 1
Note: When using mouse and touchscreen simultaniously, make sure to specify the right mouse
device and not /dev/input/mice, since this might cause the mouse to interfere with touchscreen
button handling and always generate a ButtonDown 1 event when touching the screen!

Changes (for full description see ChangeLog file after patching (-: ):
- Changed code to compile a working driver for both
XInput ABI 0.x and 2.0 (Xorg 1.4.0)
- changed rotation (due to segfault on xorg + fbdev)
- drag support
- tap "tolerance"
- added generic ts-adc touchscreen device to udev rules file
