I'm not able to scroll by my touchpad after reboot. When I set from System > Preferences > Pointing devices the vertical scrolling, it works till reboot.

My X11 current configuration is:

I set up X11 as you can see because touchpad stopped to work after fn+f7 (disabling it by keyboard). Now it seems to work restoring old x11 conf file, but I'm quite afraid to disable touchpad when I'm using normal mouse. What do you advice for enabling/disabling touchpad easily and successfully, since fn+f7 doesnt enable it anymore? –  Valerio Giuffrida Jun 20 '11 at 6:25

I'm a bit surprised to see a pointer still in the X11 configuration file, that's quite a legacy way of doing things. I expect it is these settings that are overriding the changes you make every time.

Unless you already know you specifically need to configure your device using the xorg.conf (i.e. nvidia drivers) you can try taking the 'input device' section out of the file (don't forget the entry under "server layout" too.)

Backup your configuration before you try this, so if you do lose your mouse you can simply open a terminal (CTRL + ALT + T) and restore the file using the keyboard.

Did you check the mouse configuration? My touchpad can be configured by the mouse settings. May be you have conflicting settings. as pointing device is an additional GUI.

FINALLY beat this one. All I had to do was open Ubuntu's "Startup Applications" and REMOVE "Synaptiks Touchpad Manager" from the list. Now Ubuntu's default Mouse Settings application works perfectly, and saves settings.
