[Bug 1178796] Re: [Asus UL80VT] Backlight control does not work, but there are entries in /sys/class/backlight
Well, I could file a new report with this particular setup (BIOS parameter SATA in mode Compatible, Intel graphics card disabled) if it helps to fix nouveau not adjusting brightness correctly (hotkeys with nouveau works in Precise and Saucy) . But I am not willing to keep using this setup as the nvidia card consumes more power than the Intel card. -- 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

Guillaume Millet, given the nvidia drivers works except via hotkeys, it would be easier to pursue a fix for this, versus fixing both nouveau not adjusting brightness correctly, and hotkeys with nouveau. Hence, with the setup noted in https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178796/comments/52 in please, could you please file a new report via: ubuntu-bug linux and include the information in https://wiki.ubuntu.com/Hotkeys/Troubleshooting . -- 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

Guillaume Millet, ok. It looks like in Saucy nouveau just failed to enable the discrete card altogether. Despite this, in your Raring install, if you uninstall Bumblebee (which isn't provided by a supported Ubuntu repository [1]), remove all non- default kernel parameters (ex. video.use_bios_initial_backlight=0), and switched to the nvidia drivers [2], are you then able to adjust your backlight without any further modifications?

Guillaume Millet, this would not come from from the package acpi- support, it's either a userspace or kernel issue.

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.
