I have a fresh installation of Karmic Koala which keeps freezing very soon after login. I had this problem before with the same machine and the previous time I believe I solved it by booting up in safe mode and disabling all power management software, and then rebooting. However, I can't remember how I disabled the power management stuff. I don't remember if it was APM or ACPI or what.
Can you tell me how I can disable all power management stuff?
