I've got an Acer 7720 -6208 (with Intel X3100 graphics), Ubuntu 8.10 64bit.

The problem I have is that I can't resume from suspend or hibernate. When I try to resume, the screen lock window comes up where I can enter my password. I enter the password and the system looks like it's going to resume (I see my desktop again), but then everything locks up (screen is frozen). I can't ctrl+alt+del, or ctrl+alt+backspace, or get into a virtual terminal. Only thing to do is just hold the power button down and force the power to go off.

Any ideas?
