Following up, the gnome power settings workaround helped slightly, but I still got lots of crashes and unsuspend failures. I did end up going w/ 32 bit Ubuntu 11.04 + nVidia binary driver and things are working quite smoothly now, albeit with 1/2 the bits :-P
Changing the brightness works great after I add Option "RegistryDwords" "EnableBrightnessControl=1" under the "Device" section of my xorg.conf. So who knows why this works fine in 32 bit-ville but not 64? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/776999 Title: [Lenovo W520] laptop freezes on ACPI-related actions To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/776999/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
