Synaptics TouchPad became slower

[Alex Muntada]

Since I upgraded my Ubuntu from Breezy to Dapper my Synaptics TouchPad became much slower and the button-events (through touchpad press) don't work anymore; I must press the actual buttons. I tried changing mouse motion preferences, but it didn't have any effect on the Synaptics TouchPad behaviour.

Just upgraded my Ubuntu from Breezy to Dapper this weekend and the most obvious failure I see is that my Synaptics TouchPad became slower and the button-events (through touchpad press) don't work anymore; I must press the actual buttons. I tried changing mouse motion preferences, but it didn't have any effect on the Synaptics TouchPad behaviour (I need 7 movements to move the mouse pointer from one corner of the screen to the opposite).

I'm guessing it's a Synaptics driver failure because if I plug an USB mouse, that mouse works fine.

BTW, the xserver-xorg-input-synaptics version installed is 0.14.3+seriouslythistime-0ubuntu2.

I found a duplicate candidate for this bug report, though I haven't experienced problems until I upgraded to Dapper (before that the TouchPad worked fine):

It turns out that my TouchPad is an "AlpsPS/2 ALPS GlidePoint"
as reported in /proc/bus/input/devices. Adding all the touchpad
options from the following file solved the issues:

Thanks to the Synaptics FAQ about the ALPS GlidePoint options:

I've discovered how to solve this.

Dunno how to proceed now...

Should I consider the bug resolved? The thing is that this will most probably be an issue for a lot of people too.

#28648 is a Dapper only problem so I marked this as a duplicate.

Touchpad Press has been disabled self-aware as far as I know. You can change this by edititing your xorg.conf file.
