Hi Christopher, I have tried ubuntu-12.04.2-desktop-amd64.iso and ubuntu-12.04-desktop-amd64.iso: the brightness applet reacts to the hotkeys but the brigthness of the screen does not change.
I thought it was working before 13.04 but I don't remember whether I tweaked something. Maybe I added acpi_backlight=vendor, shall I tried the same old-releases with acpi_backlight=vendor? Do you need me to attach dmesg report for each? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1178796 Title: [Asus UL80VT] Backlight control does not work, but there are entries in /sys/class/backlight To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
