For the OP, you have to set the "dim brightness by" to "0%" in order for it to be fully bright.
I have a related problem, however, in that if I set it to 0% and then dim it manually, it will "dim" to full-bright when idle. This is counter-intuitive. -- screen brightness doesn't return to proper level https://bugs.launchpad.net/bugs/136282 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
