[Bug 868400] Re: Synaptics touchpad stops working

 

"synclient TouchpadOff=0" has no effect for me.  That setting is
toggling correctly as I start/stop typing.  Also, I have the exact same
problem whether "disable touchpad while typing" is enabled or not.

It isn't just that the touchpad stops responding, it also sometimes goes
berserk.  The problem seems to worsen the longer the OS is running.
Right after booting, it actually works for a couple minutes.  By the 10
minute mark, it's so bad I can hardly even work with it using an
external mouse.

This is probably unrelated, but I installed gpointing-device-settings to
get some additional controls while troubleshooting this problem, and
some of its options don't seem to stick.  Such as disable touchpad when
another device is connected.  The setting will be unchecked again after
reopening the program, and the setting never takes effect.
