unable to run gsynaptics on lenny
os : lenny 5.0.4
i have run gsynaptics from command line :
and it has shown the following error :
GSynaptics couldn't initialize.
You have to set 'SHMConfig' 'true' in xorg.conf or XF86Config to use GSynaptics
i have edited the file of /etc/X11/xorg.conf and added support for synaptics.
Identifier "enable synaptics SHMConfig"
Option "SHMConfig" "on"
but, when i try to run # dpkg-reconfigure -phigh xserver-xorg, i am receiving the following error :
xserver-xorg postinst warning: overwriting possibly-customised configuration file; backup in /etc/X11/xorg.conf.20100928233119
how should i overcome the above error.
