My problem is that in a random but frequent fashion left click on the laptop mouse buttons fails to work and that, again frequently, random pastes from the clipboard appear in the window where the cursor is placed. I can usually get left click to work again by switching to another workspace and back with the keyboard, or by first right clicking in the appropriate space on the desktop - or often by just waiting for several seconds. When the random pastes start, in say a terminal window, more pastes can be triggered by just rocking the computer back and forth. They do not happen when I am not touching the machine.
The occurrence of these two problems is not consistent and I can discern no pattern that specifically triggers them. When they do occur the machine becomes essentially unusable. I have searched the web and the ubuntu forums for others reporting this behaviour, and can find nothing closely related.
All of this leads me to wonder whether I have is a hardware fault or a software bug. The machine is a Lenovo Thinkpad T410 with an SSD drive and discrete (NVidia) graphics. I am running Maverick 64 bit with the nvidia-current driver. Turning compiz on or off has no effect on the behaviour. I have recently done a clean install of everything to try to fix the problem - to no avail.
To try to stop this behaviour I have also disabled the touchpad in the bios - which by the way has just been upgraded to the latest version - but this does not affect the problem either.
