U810 Buttons and Touchscreen Part 1

The Fujitsu touchscreen Lifebooks are Novell/SuSE certified so where are the drivers? They're not in the released mainstream OpenSuSE distro (10.3) but they have to be somewhere. A bit of digging gets me to the OpenSuSE Tablet PC pages which look rather promising - there's an evtouch package for the touchscreen and a Fujitsu button driver too. The T/P series tablets are mentioned but I'm hoping the U series will be covered too as I doubt Fujitsu would re-engineer a different mechanism unless they really had to. These drivers are currently listed as unsupported but I hope they make it into the mainstream 11.0 release or soon after.

Adding the OpenSuSE Tablet PC Repository to YAST allows us to pull down fsc_btns which looks like a good shot for a button driver (there's also a fair bit of Fujitsu-related activity in the Linux ACPI Project itself so this may be a stopgap). So I attempt to download it and discover it has a dependency on an earlier kernel than the one I have.

Okay, install the basic development packages and kernel source from the main repository and get the fsc_btns source from the SRPMS. Then proceed as follows...

1. cd /usr/src/linux
2. make cloneconfig
3. make modules prepare
4. make coffee, eat lunch :)
   
5. cd /usr/src/packages/SOURCES/fsc_btns
6. make
7. make install
8. modprobe fsc_btns
9. "No such device" :(

Okay, time to look at the source code then...
