On a Dell C610 running Hardy Alpha5 the dimmer works on AC, but not on battery. I assume that's how it's designed.
On AC it indicates that it dims from 100% to 0%, but this is not quite right. The lowest setting (0%) does not blank the screen, but puts it at where the screen is on battery power. -- "Display brightness" slider does not show up on Dell Latitude D810 https://bugs.launchpad.net/bugs/116464 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
