Tried again (Dell 1555, Radeon 4500 series): "noapic acpi=force nolapic" works brightness and suspend on close lid, but it doesn't recognize my core duo as dual core.
With any other combination of those flags I get two cores but brightness and lid close stop working. Is there any progress to this bug? It works on grub screen, so I guess some kernel module / config is screwing up. As this happens with both fglrx and open source drivers, I doubt we can blame ATI... cheers, --renato -- Dell Studio 1555: cannot change display brightness after a while, other hotkeys and ACPI stuff begin to fail https://bugs.launchpad.net/bugs/392812 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
