This appears to still be the case on portables, specifically for me, on a Lenovo SL500. Using the Function key to increase brightness by pressing the "brightness UP" key combo, will raise the display brightness by one notch; subsequent key presses will then decrease the brughtness a single notch, and so it goes - each additional press either raises or lowers teh display brightness. To get a comfortable brightness level, i have to reboot the laptop.
On a side note, volume up, down and mute buttons do not work either. -- Cannot change screen brightness on Fujitsu T2010 laptop in Intrepid https://bugs.launchpad.net/bugs/220407 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
