touchpad left-click ceased to work after update

[kenstad]

Everything has worked fine for months but after an automatic update by the update manager my touchpad no longer recognises left clicks - neither tap nor button - and on the first touch on the touchpad after login I get a hanging left click (a dotted box outline for selecting multiple items). Essential system info:

Any idea anyone?

Feisty is not supported anymore.

[sedesc (sedesc-riseup)]

I can confirm this bug under intrepid. I had the same bug with several versions of ubuntu (including feisty) but since intrepid its no working a all.
After a restart of the xserver the tabbing works again but not the left mouse button.

greetings

Same problem here on "Karmic" 9.10
on update i lost the touchpad click/doubleclick but i can use the buttons to click left and right..
it's very annoying to lost the touchpad clicks
although it still scrolling vertically
FYI: the touchpad clicks into "Mouse configuration" is enabled
