Have you tried both hibernate and suspend? Are the results the same? Have you tried changing other settings in /etc/default/acpi-support?
I've just fixed hibernation for me (nvidia 6600GT) by setting SAVE_VBE_STATE=false, so there is hope. -- Hibernation and suspend is not working https://launchpad.net/bugs/61480 -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
