Also retested now with a mainline-kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.11-rc7-saucy/) in my kubuntu (precise) setup - problem still persists - brightness can't be controlled (neither with ctrl + coursor, nor with the widget). Output of dmesg is attached.
Linux 3.2.0-52-generic + "acpi_backlight=vendor" using KDE btw works without any restrictions. ** Attachment added: "dmesg.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/907555/+attachment/3806313/+files/dmesg.txt ** Tags removed: needs-upstream-testing ** Tags added: kernel-bug-exists-upstream kernel-bug-exists-upstream-sala ** Tags removed: kernel-bug-exists-upstream-sala ** Tags added: kernel-bug-exists-upstream-v3.11-rc7 ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/907555 Title: Brightness-Troubles with Acer Travelmate 8481TG To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/907555/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
