This has happened to me several times but it might not be a problem with Ubuntu. I have a Thinkpad Edge 14 and I dual boot both Ubuntu and Windows 7. Whenever this happens the Fn keys stop working in both Windows and Ubuntu which indicates that it's a BIOS/hardware issue. I usually fix it by simply flashing the BIOS.
Apparently it's a common problem with Edges: http://forums.lenovo.com/t5/ThinkPad-Edge/Hotkeys-no-longer-working-ThinkPad-Edge-14-Windows-7/td-p/323077 -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-settings-daemon in Ubuntu. https://bugs.launchpad.net/bugs/1028518 Title: Fn keys such as brightness and volume stopped working after update To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-settings-daemon/+bug/1028518/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
