Well, I'm lost. It seems not related to linux-image, as the kernel image 3.5.0-17.28 (quantal release) does not work either. So it may come from another package update, acpi-support?
other notes: - sudo setpci -s 00:02.0 F4.B=HH with HH between 0 and ff works. - echo 258366 > /sys/class/backlight/intel_backlight/brightness works (values between 0 and 2583660) - /etc/acpi/asus-keyboard-backlight.sh looks for /sys/class/leds/asus\:\:kbd_backlight. I have no such entry (acpi-support_0.141). -- 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
