Pine64 Touch Screen (TS) with TSLIB on X11

[@lex]

If someone is interested i have compiled some TSLIB deb packages for the Pine64 Touch Screen to work without evdev driver or any other service behind.

 

Advantages:

 

* Easy to install (if you know how to edit xorg.conf)

* No service needed

* No calibration needed

 

Disadvantages:

 

* works on X11 only

 

Information and deb packages:

Hope it can be useful.

Hi and many thanks for your work with the tslib X11 driver.

 

I tried following this on a pine64+ running kernel 3.10.104-pine64

 

 

but X is failing to start with a segfault:

Any ideas?

Answering my own post, I had an empty /etc/pointercal file, which was causing the segfault. Removed it and x started fine, using the driver.

 

  Thanks again!
