Default Video Driver

I've installed lubuntu 12.04 x86_64. The mouse is not working correctly. In debugging it looks like I'm having trouble with the video driver (I'm not sure this is at all related to the mouse problem). I am way over my head at this point and need some help. I have included some debug output on the video driver showing problem with interrupt handling. Any guidance/comments would be greatly appreciated. Thanks.

John

I don't know what the current status of the nouveau open source driver
is, or what kinds of performance you should expect from it. However,
traditionally, Nvidia cards really need the proprietary driver from
Nvidia to work well.


Somwhere in the Lubuntu menu should be the 'Additional Drivers"
application that will scan your system for hardware that needs 3rd party
drivers and offer to install them for you. Try that, and have it
install any Nvidia drivers it suggests.

Thanks Rashkae. Problem solved. I installed the priority driver following the procedure just as you suggested and the interrupt problem was corrected and the mouse appears.
