Thank you, Boyd, that was just the sort of answer I was looking for. I tried using Ctrl+Alt+F1 to drop into a terminal but, again, it wasn't responsive. I'll commit your suggestions to memory for the next time the system locks up. You touched on the crux of my complaint: sure, I expect the odd

Thank you for your reply, Axel; perfect answer. Now that I know that these features of Linux exist I can go hunt them down and figure out how to use them and stop this from happening again (like it did after I sent my original e-mail). With thanks again, -- To UNSUBSCRIBE, email to debian-user
