Login screen does not appear after disabling screensaver

When my screensaver is running and I press any key or mouve the mouse, the login screen is supposed to appear, and it does so, but only 50% of the time, I’d say. The rest of the time, the screensaver animation just freezes, and the only way to login is to toggle between ctrl+alt+f1 and alt+f7 to force the display of the login screen.

Any idea what the problem might be? If I press ctrl+alt+f10, I see some messages about some fgl interrupt having failed (sorry not to be more precise, I’m not in front of the computer right now). Could this be linked to the proprietary ATI driver which I have installed?

Thanks.

Back at my computer… Here are the messages that appear in /var/log/messages :
