same hear for my Dell Inspiron 9200. Fn+F6 doesn't work but no i810 it's a ATI Mobility Radeon 9600 M10 with a RV350 chip..
I don't know if there exists a solution or it is impossible for a ati card? -- Fn+F4 doesn't switch to ext monitor Compaq 4020us (all other Fn keys fine) https://launchpad.net/bugs/43293 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
