Comment 95 for bug 549727

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.
