Hi Christopher.. Bug still exist in 12.04 after system updated yesterday, same behavior.
There is also same behavior with 14.04 daily, I'll do reporting shortly. ** Tags added: apport-collected reproducible single-occurrence trusty ** Description changed: Seems that strange behaviour happen after I start system to Windows 7, then restart my laptop (soft reboot) to Ubuntu. Restart & restart again to Ubuntu not make brightness keys working. The issue solved when I shutdown my laptop (hard reboot) then power on again to Ubuntu. -> brightness keys working again (even on AC powered) I think the issue is: after starting Windows 7, system has to shutdown (hard reboot) before starting Ubuntu.
