I have the brightness issues on Karmic with kms as well with a Samsung x360 laptop.
/sys/class/backlight/... is populated and looks okay, but there is no visible change in brightness when altering the values. Booting the kernel with 'nomodeset' makes brightness work again. xbacklight says "No outputs have backlight property" -- brightness no more working on karmic (KMS) https://bugs.launchpad.net/bugs/397617 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
