I know this is marked as fixed, but I am having what appears to be the same problem on an Acer aspire timelineX 1830T in karmic kubuntu, fully updated. I wondering if it is a regression or if this model needs another patch.
With either xbacklight or the hotkeys, no change is made. After applying acpi_backlight=vendor to the grub config and rebooting, a backlight directory appears as: /sys/devices/platform/acer-wmi/backlight/acer-wmi/ actual_brightness bl_power brightness device max_brightness power subsystem uevent max_brightness is 9. I can echo into brightness, and that number changes, but no effect in the display. actual_brightness is always stuck at 0. -- Acer Aspire 5520 has backlight broken in Karmic Koala https://bugs.launchpad.net/bugs/428910 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
