I have found a solution to brightness changing if you have gone the 32bit route to solve the issues in this bug report.
In Kubuntu 11.04 32-bit, change to a virtual console, ie: alt+ctrl+F1, change brightness with Fn+brightness to the desired level, then alt+ctrl+F7 to get back to X and the level should be retained. This isn't the most elegant but it is repeatable for my machine. Also for what it is worth, it seems that other distros are not having these problems. I have read reports of very happy slackware and Gentoo users running 64bit gnome and KDE on the w520 with Discrete graphics. I simply haven't had the chance to mess with trying something else yet. -- 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 [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
