I can confirm this on my Dell Inspiron 1501 After blacklisting video (add blacklist video to /etc/modprobe.d/blacklist) it doesn't crash anymore but the brightness- keys do nothing
The fixing of the brightness-keys is being done in https://launchpad.net/ubuntu/+source/hal/+bug/43572 -- 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
