X overflow, infinite loop [was: Problem/regression on ETPS elantech touchpad]

2011-03-26 Thread Pier Paolo
  Last upgrade (squeeze 6.01) messed up X server for me; it has to do with
my previous ETPS touchpad issue, as far i understand, it has to do with
synaptic_drv.so; with both KDE and Fluxbox. Repeatedly and frequently. Have
to submit a bug? to xserver-xorg-input-synaptics? Logs / backtrace attached:

 Sorry to top post this, but I'm in a hurry.  I actually got my
 touchpad working again.  I'll dig up the documentation that I used and
 post it when I find it, unless someone else is able to get it to you
 first.  It has something to do with creating a configuration file and
 setting something with modprob up.

 thankyou, hope forseeing some: i got my touchpad working, but as a
macintosh one or something... (see xorg.log below)
and yes, create a 55- /etc/X11/xorg.conf.d to overcame
/usr/share/doc/X11/50-synaptics.conf
and actually scrolling and going around is very troublesome...

please help ;) (it is not only a matter of synaptics parameters...)
