This happens also on a Thinkpad R61, with Gutsy final release. Additionally, writing to the proc node with commands like echo level 7 > /proc/acpi/ibm/brightness changes the value reported by the node, but it doesn't change the actual brightness.
The Fn+key combinations to change brightness work, but only when accessing a console via CTRL+ALT+Fn See also bug #137972 -- Screen Brightness Little Pop-up window does not show the correct Brightness on Thinkpads X60, T60p, Z60t https://bugs.launchpad.net/bugs/71204 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
