I can confirm that this bug is not present when you put the laptop into hibernate.
i.e. boot laptop. brightness keys don't work, run xrand command, brightness keys work (yay!), put laptop into hibernate, wake from hibernate, the brightness keys work! -- Putting laptop to suspend breaks the brightness control https://bugs.launchpad.net/bugs/351443 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
