Public bug reported:
Binary package hint: xfree86-driver-synaptics
I wanted to modify the acceleration parameters of my ALPS touchpad on a
DELL D630 laptop. As gsynaptics was not working due a SHMConfig
parameter not set to 'TRUE', I tried to define a corresponding
"InputDevice" entry in xorg.conf with no success. After googling around,
it seemed that the best way was to create/modify the associated HAL
configuration file.
When adding option lines under "AlpsPS/2 ALPS" in
/usr/share/hal/fdi/policy/20thirdparty/11-x11-synaptics.fdi, computer
sometimes freezes during boot with a completely scrambled display. A
simple '<merge key="input.x11_options.SHMConfig"
type="string">true</merge>' causes the effect. I also tried to directly
set the desired parameters as shown in the 11-x11-synaptics.fdi
attachment. The definition of these ALPS parameters in a
/etc/hal/fdi/policy/11-synaptics-options.fdi file leads to the same
problem.
