Ubuntu 13.04 - Keyboard and power button not responding
I've had this problem ever since I installed Ubuntu 13.04 amd64 on my laptop - basically, it starts up with some error messages about ACPI (I can't remember them, but I don't want to boot to Ubuntu again to prove it in case my method of 'shutdown' knackers the computer), and when it boots, no keypresses are registered and I can't even use the power button on the laptop to force it to power off. Shutting down the computer normally doesn't work either, and goes as far as a blank screen and then stops.
Is this a known issue? It's essentially rendered Ubuntu useless, although I could try to downgrade to the LTS version, which seemed to work OK.
