Slackware touchscreen mini-HOWTO. Written by V'yacheslav Stetskevych, 2010.
|
|
This howto will help you set up your touchscreen using the evtouch driver.
|
|
|
|
This driver bundles an udev rules file /lib/udev/rules.d/69-touchscreen.rules,
|
|
that lists known supported touchscreens and creates a symlink to the correct
|
|
event file for them. A lot of touchscreens are supported, but still more are
|
|
capable. If you find that your touchscreen works with this driver, add it to
|
|
the udev rules file and send your lshal output to ubuntu-mobile@lists.ubuntu.com
|
|
to get it added to the driver.
|
|
|
|
To make use of the driver, you will have to make edits to /etc/X11/xorg.conf
|
|
(create a fresh one if it doesn't exist, or generate one with 'X -configure'):
|
|
|
|
Section "InputDevice"
|
|
Identifier "Touchscreen"
|
|
Driver "evtouch"
|
|
Option "Device" "/dev/input/event#"
|
|
Option "MinX" "0"
|
|
Option "MaxX" "1000"
|
|
Option "MinY" "0"
|
|
Option "MaxY" "1000"
|
|
Option "ReportingMode" "Raw"
|
|
EndSection
|
|
|
|
If you had an xorg.conf already, add the following to the ServerLayout section:
|
|
InputDevice "Touchscreen" "AlwaysCore"
|
|
|
|
If your device is supported, a symlink /dev/input/evtouch_event will have been
|
|
created for you by udev. Specify this symlink as the Option "Device" parameter.
|
|
|
|
If your device is not supported by the udev rule, find out it's event number by
|
|
looking at /proc/bus/input/devices. It should list your device with a line,
|
|
that says "Handlers=event3 mouse2" or something similar.
|
|
You may verify that your touchscreen is operable by issuing
|
|
cat /dev/input/event# (replace '#' with your number)
|
|
and tapping your touchscreen. Random characters should appear on the screen.
|
|
Note the event name, and use it as the Option "Device" parameter in xorg.conf.
|
|
(Or better, add your device to the udev rule file to get a persistent symlink).
|
|
|
|
Be sure to calibrate the device and record the correct parameters in your
|
|
xorg.conf, see README.calibrate in /usr/doc/xf86-input-evtouch-$VERSION and
|
|
find the necessary helpers in /usr/lib/xf86-input-evtouch. The calibration tool
|
|
may not work for your touchscreen model, in that case try and set the right
|
|
values in xorg.conf manually. That involves some guesswork, but works.
|
|
|
|
See the driver's homepage for additional options you can put in xorg.conf,
|
|
like Rotate, SwapX, SwapY and button action assignment.
