Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I have a midrange PC (Intel Core2-Duo 3GHz, 4GB RAM, 1.5TB storage), with latest Ubuntu 11.10 (Oneiric) and Unity (3D).

Description: PC does NOT always return control after automatic timeout to screen-saver -- does NOT prompt for password, keyboard and mouse are still active but NON-functional, and is non-recoverable (requires power-off).

This appears to be a race condition between mouse and keyboard. When I absently move mouse (to exit screensaver) and then quickly enter password (unprompted), this lockup condition occurs ..

Is this a known issue? Can it be resolved?

A similar mouse/keyboard zombie-state is described in: (but for Ubuntu 11.04)

Freeze when resuming from screensaver or monitor-sleep-state

UPDATE

Since update to kernel 3.0.0-14 (today) this has happened 3 times.

This has happened to one of my friends. We installed GNOME 3 and it stopped. I'm not sure this was the answer you are looking for but nonetheless, it is a solution.
