Why do the old settings in /etc/xorg.conf disappear after I install the PenMount Device Driver ? How do I get those settings back?
The PenMount Linux device driver V2.3.0.15 and V2.4.1 will first backup /etc/X11/xorg.conf during installation and then overwrite it with PenMount specific settings to ensure that the touch screen operates correctly. If you have other settings in the original /etc/X11/xorg.conf, you will need to copy them manually back to the /etc/X11/xorg.conf. The backup of xorg.conf can also be found in /etc/X11/ with its original name concatenated with date and time.
