My variant of the 6930 has ATI graphcs (Radeon HD3400 series). My screen brightness experience is somewhat better than you describe. The Fn- controlled keys on the keyboard work for brighter/dimmer; the gnome applet also works; the brightness state agrees between these two methods. xbacklight says "no outputs have backlight property".
However, ambient brightness detection doesn't seem to work. Nothing happens when I press Fn-F11 which is supposed to go to auto mode. If I'm on battery, sometimes the screen will dim itself to 44% and I have to go manually readjust it to the desired level, and it won't stay there for long; it'll keep jumping back to 44%. If I'm plugged into AC, then the brightness stays where I put it. Also the "dim display when idle" checkbox in the gnome power preferences is somewhat funny, but I suspect this isn't hardware-specific. Its definition of "idle" sees mouse but not keyboard input, and always kicks in after 1 minute, regardless of what delay I specify in the screensaver preferences. So if I have "dim display when idle" selected, the screen will often dim when I'm not idle (I frequently go more than a minute without touching the mouse!). So, I've deselected the dim-on-idle option. -- mute, brightness buttons on new HP 6930p laptop https://bugs.launchpad.net/bugs/284319 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
