Hi,
I am developing the touchscreen driver for the Lifebook B-Series.
Newer versions of X enforce the setting "CorePointer" in the file
XF86Config-4 (older versions did not). If "CorePointer" is set KDE and
Gnome seem to stall (Well actually the X-Server exits with Signal 11).
It seems that a call to the Function "XGetPointerControl" causes this
fault. Below you'll find the source of a little test program which
causes the error. This error is independent of the version of my driver
you use (download from www.conan.de/lifebook/lifebook.html). I think
someone from the xfree-team has a 2154-model of the B-Series -- it
would be very nice if he could help me and try to find out more about
this failure.
I think something is wrong in my driver but the X-Server shouldn't
stall either.
Below you find the test program and my XF86Config-4 which causes this
error.
Thank for your help
Kenan
