Hi Johannes, sorry for the late answer. I’ve been busy recently, and it seems Jan even more so. Genrally, you’ll get faster responses on a mailing list.
I’m sending my reply to smartphones-userland, as others might have interesting things to add. Note that you need to be subscribed to post to that list.

It’s a valid point. I guess we could improve the installer.sh to optionally exclude fso-stuff from being installed. > a problem i currently encounter concerns the touchscreen of the neo1973 > and freerunner which stopped being calibrated correctly with the latest > updates of xserver-xorg-input-tslib to version 0.0.5. > even though the /etc/pointercal stayed the same the cursor is in the > wrong place. a user in the openmoko wiki documented this behaviour in my > guide and found out an alternative pointercal by trial and error. > > instead of doing the same i wanted to have this issue fixed so i joined > the #debian-arm channel and got immediate help by codehelp. > > ts_test and ts_calibrate from the libts-bin package work correctly and > ts_test lets me draw in the correct position but the pointercal file > generated by ts_calibrate is afterwards read incorrectly by the xorg > driver. codehelp told me that this is only and issue on *some* devices > as he has the same on his balloon board but the new tslib xorg version > worked fine on other hardware. > apparently ts_test always works correctly on all devices and the only > problems only occur when xorg with the tslib driver comes into the mix. Yes, this is my understanding as well. ts_test is producing an authoritative pointercal file. > another issue is the documentation of libts-bin - i had a hard time > finding out these env variables that are documented nowhere and are even > hard to find out about in the internet [2]: > export TSLIB_TSDEVICE=/dev/input/event1 > export TSLIB_CONSOLEDEVICE=none > export TSLIB_CALIBFILE=/etc/pointercal > export TSLIB_CONFFILE=/etc/ts.conf > export TSLIB_PLUGINDIR=/lib/ts > export TSLIB_FBDEVICE=/dev/fb0 > export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib > > without the first three ts_test and ts_calibrated refused to work but > there was nothing to find in the corresponding man page. There was some process on http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=497516 but I’m sure the libts-bin maintainers appreciate any help there. > the last thing i want to bother you about is some patches that > suihkulokki pointed out here [3] > > but maybe codehelp already forwarded those patches.

I hope that the others on the list can comment on the pointercal problem, to see if it is really a problem. At least I thought that X would now happily use the same pointercal that’ fine for ts_test, but that is on a FreeRunner. Maybe the neo1973 is different?
