Binary package hint: xorg
I have used 9.10 and earlier releases on this hardware daily with no problems, but after an upgrade to 10.04 I experience the following problem once for every several hours that I use the machine. There is no specific trigger that causes it. The symptoms are that suddenly the keyboard becomes unresponsive. This includes low-level features like activation of the CapsLock indicator light, though Alt+SysRq+o is effective. I am able to move the mouse pointer, but mouse clicks have no effect. There is no corruption of the display. I am able to SSH in to the system, and when I do I notice that xorg is at 100% CPU usage. I have found nothing in any log that indicates a problem, but perhaps you will be able to do so.
