The plpevtch driver is an eventdevice driver for touchscreens under Xorg 7.x.

Why another touchscreen driver when evtouch already exists? I was using evtouchon my Flybook with Xorg 6.9 very long. But with Xorg 7.3 it was not working for me. ShortlyI bought a touchscreen and I was not able to get it to work with evtouch. Then quickly Icreated this new driver and it works in the way I want. plpevtch is not a fork of evtouch.

Supported Hardware

I have only 2 different touchscreens, so i can only say that it works for those. Butthe driver should work with any other eventdev touchscreen kernel driver too.

The driver was successful tested on

How to calibrate

  • add Option 'Calibrate' to the touchscreen section

  • restart the X server

  • move along the borders of your touchscreen multiple times (ignore the mouse pointer). Its required to get the minimum and maximum values of your screen.

  • search /var/log/Xorg.0.log for the last 'plpevdev' and 'Calibrate'. You will see something like

    (II) touchscreen: Calibrate MinX: 67 MaxX: 1984 MinY: 42 MaxY: 1920

    use this values in the touchscreen section of your xorg.conf

  • remove the Calibrate Option in the touchscreen section

  • restart the X server


If your Xorg is installed in /usr/X11R7 then run
./configure --prefix=/usr/X11R7 && make && make install

If your Xorg is installed in /usr then run
./configure --prefix=/usr && make && make install
