[Bug 549727] Re: [10.04] Touchpad stops working after login

 

I too experience this problem since a few days, probably after an
update. At home I always use a mouse, so I did not notice until
recently. I have an Acer Aspire One ZG5 with Ubuntu 10.04 2.6.32-22
generic. My touchpad is completely dead for all users. Unlike others it
does neither temporarily work at the login screen, nor randomly, nor for
a limited period. I tried Fn-F7, gconf-editor (Touchpad is enabled),
mouse settings menu, checked outputs from dmesg | grep Touch, xinput
list-props "SynPS/2 Synaptics TouchPad" and cat /proc/bus/input/devices.
Nothing special found.

Then I booted from a USB start-up stick with Ubuntu 9.10, with the
expectance that touchpad would work again which would allow me to find
the differences in settings. Guess what: it did not. I did the same
listings and settings check, compared with the previous investigations.
Again found nothing weird. Unless the problem was also present in the
ubuntu-9.10-desktop-i386.iso (I maybe did not notice then since
immediately after installation there were many updates), it leads to my
suspicion that it the problem is resident in the netbook. Does this help
anyone to find the root cause? Can anyone confirm the same behaviour on
his laptop? I realise it could even be a hardware problem. Nevertheless,
I'm still looking forward to a solution.
