After sitting for quite some time I fired my old Dell inspiron 1100 up. I noticed my touch pad being extremely "touchy". I went to check my xorg.conf and it was gone. I had the following files in X11: xorg.conf-fbdev, xorg.conf-vesa, xorg.conf.backup, xorg.conf.in.
the xorg.conf.backup file was apparently correct so I copied it to xorg.conf and restarted x and all appeared well (so far)
Anyone got an idea what happened?
