Comment 29 for bug 571534

I have the same problem in ubuntu 10.04 with a logitec wired usb mouse on a medion MD96970 laptop (intel): the mousebuttons stop working randomly (both buttons, the wheel and the touchpad taps and buttons).

Before the problem occurs I sometimes notice that in vuze legacy UI items from the torrent lists tend to be selected when I move over them, but when I left click on one item all other items are deselected.

The problem usually starts with the panel and the top window panes not reacting to clicks, this can be fixed by using alt+f4. Two keyboard shortcuts also stop working, those being: alt+tab and alt+f1. Alt+f1 does highlight the applications button but does not open the menu.

Shortly after reviving the panel function the mouse stops working again, this time clicks within applications do not work either. Sometimes ctrl+alt+backspace or alt+sysrq+k works, but sometimes it does not. At this point, when I try alt+f2=>"gksu reboot" I get an error message stating "Cannot grab Mouse", so I tend to fix the issue by opening terminal and "sudo reboot".

This bug seems similar to bug #41301 except that in #41301 it is mentioned that the keyboard works perfectly. So, as I think a malfunction in alt+tab is rather noticeable during a mouse defect, I decided to comment in this report.
