Re: Synaptics touchpad work in gdm, stop working under gnome

gnome once logged is overwriting some of the xorg settings for touchpad. to configure use System->Preferences->Mouse and then TouchPad tab

Give what you have. To someone, it may be better than you dare to think.

You're looking for the gconf-editor command.

Re: Synaptics touchpad work in gdm, stop working under gnome

I too am having the same problem. This only seems to happen after I connect to a projector by the VGA port on my Lenovo T500. I use the display port to connect to a 30" apple cinema display and have no issues. Have not had much luck in finding what changes in the gnome config when this problem arises.

I am looking forward to anyone being able to explain what is actually changing and why. WIll continue to dig into this and post a workaround if I find one.

Re: Synaptics touchpad work in gdm, stop working under gnome

Not sure if this fixes your issue, worked in the case that I posted above.

Remove psmouse kernel module and reload as follows:

modprobe -r psmouse
modprobe psmouse proto=imps

This should at least get the mouse working until a better answer comes along, I have written a script that runs this after I login to gnome. YMMV.

Do you have gsynaptics installed? If yes, put gsynaptics-init in autostart. If tapping isn't working, check settings in gsynaptics.

Re: Synaptics touchpad work in gdm, stop working under gnome

mmm...  I fixed this problem by enabling trackpads in gconf: "/desktop/gnome/peripherals/touchpad/touchpad_enabled".
