It also occurs on my Dell XPS M1210. Adding blacklist video to /etc/modprobe.d/blacklist fixes the issue, and the brightness control works as expected (it's handled in hardware, not software, as evidence by the keys working in GRUB or while Ubuntu is starting).
Dapper did not have this issue, as far as I can recall. -- Fn + Arrow Key Crash https://launchpad.net/bugs/75263 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
