Shutting laptop lid crashes machine.

[rasmack]

So, I just tried Linux Mint for the first time (4.0 Main edition). Everything works fine and I was suitably impressed until the first time I had to shut the lid of the laptop and grab something behind it. When I opened the lid again I found only a black screen with the pointer arrow still where I left it.

I have tried setting the power management to "Do nothing" when I close the lid. Little does it help. I have run apt-get update/upgrade. No change there either. So, any suggestions?

The laptop is a Dell latitude X300.

I went to the doctor and told him my arm hurts when I move it like this. He said don't move it like that and it wont hurt.

Getting back from your medical problems to the subject at hand...?

EDIT: OK, this appears non-surprisingly to be an ACPI issue. Booting with ACPI=off provides a "fix". I guess the real question is now, how to get ACPI to work...
