Hello,
After much efforts (but thanks for the page ;-) ), I have managed to
install this on my microSD card:
http://wiki.openmoko.org/wiki/Debian
I can reach the gdm screen but the calibration of the touchscreen is
totally flaky.
After another set of painful efforts, I have managed to install
libts-bin and run ts_calibrate. If you want to know, you need to do this
from the terminal over the USB-connection:
export TSLIB_CALIBFILE="/etc/pointercal"
export TSLIB_CONFFILE="/etc/ts.conf"
export TSLIB_PLUGINDIR="/usr/lib/ts"
export TSLIB_FBDEVICE=/dev/fb0
export TSLIB_CONSOLEDEVICE=none
export TSLIB_TSDEVICE=/dev/input/event1
ts_calibrate
I get some numbers on /etc/pointercal but there are quite different if I
run ts_calibrate a few times. In any case, the touchscreen is still
totally mad and I can't use xvkbd to input the login info. In the best
case scenario, the pointer is around 200x200 pixels NW from the touch.
Then, I have played with xorg.conf. I have tried the rotate option and
many other things, but unsuccessfully.
Any idea? Thanks in advance,
Gregoire
