In case that the original submission is unclear, here's my situation in UL30A-A2.
Expected behaviour: fn+f5 lowers brightness, fn+f6 increases brightness. (worked well in Karmic) Observed behaviour, in Lucid Beta 1: Initially, when the computer is first booted, it responds to f5/f6 but in random behaviour. For example, if I press fn+f5, it would lower the brightness, then increase it to the maximum, repeat a couple times, and back to somewhat random value somewhere in between. After the initial reaction, fn+f5/f6 key no longer causes any change in brightness - for a couple minutes. For this period, acpi_listen does not seem to print out anything when these keys are pressed. After a couple minutes, these button presses seem to "queue up" and cause random changes to the brightness again - acpi_listen reports these values. video LCDD 00000087 00000000 hotkey ATKD 00000025 00000017 video LCDD 00000087 00000000 hotkey ATKD 00000025 00000018 video LCDD 00000086 00000000 hotkey ATKD 0000001b 00000005 hotkey ATKD 0000001b 00000006 video LCDD 00000086 00000000 hotkey ATKD 00000021 00000001 video LCDD 00000087 00000000 hotkey ATKD 0000002b 00000008 hotkey ATKD 0000002b 00000009 video LCDD 00000086 00000000 hotkey ATKD 00000021 00000002 video LCDD 00000087 00000000 hotkey ATKD 0000002b 0000000a hotkey ATKD 0000002b 0000000b video LCDD 00000086 00000000 hotkey ATKD 00000021 00000003 Changing the brightness manually with xbacklight shows similar behaviour - random changes, or periods of no change. Using Gnome-power-manager's brightness control slider behaves the same way. -- brightness hotkeys don't work as expected, asus ul30a https://bugs.launchpad.net/bugs/543294 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
