It used to work with the workaround suggested at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which modifies asus-brn-down.sh to use the "setpci" method. That workaround probably still works with Raring. But I had forgotten that workaround and I suspect that upgrading to Raring removed my modified scripts. So, in the original description of the bug, I thought it was a regression. But it's probably not a regression as the brightness control has apparently never worked off-the-shelf.

2013-09-15 18:28:26 penalvch description It used to work with the workaround suggested at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which modifies asus-brn-down.sh to use the "setpci" method. But I had forgotten that workaround and I suspect that upgrading to Raring removed my modified scripts. So, in the original description of the bug, I thought it was a regression. But it's probably not a regression as the brightness control has apparently never worked off-the-shelf. Not working neither with linux-image-3.9.1-030901-generic_3.9.1-030901.201305080210 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.1-saucy/ Hotkeys are detected, showkey -s: Fn+F5: 0xe0 0x4c 0xe0 0xcc Fn+F6: 0xe0 0x54 0xe0 0xd4 I also attach the results from tests described on https://wiki.ubuntu.com/Kernel/Debugging/Backlight.

But echo 8 > /sys/class/backlight/intel_backlight/brightness makes the screen dark, moreover /sys/class/backlight/intel_backlight/max_brightness = 2583660 - on 3.9.1, no brightness change but the KDE notification pops up with only 3 levels (0, 53, 100%) Test with video.use_bios_initial_backlight=0: - on 3.8.0-20.31-generic, no change. WORKAROUND: On KDE Raring Ubuntu 3.8.0-30.44-generic, bumblebee removed, BIOS SATA Compatible (to allow nvidia drivers to work, http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Nvidia_Accelerated_Graphics_Driver, note that that also disables the intel card which does not appear anymore in lspci), only default kernel parameters: The plasma widget for screen brightness (actually battery monitor) is able to change the brightness.

WORKAROUND: On KDE Raring Ubuntu 3.8.0-30.44-generic, bumblebee removed, BIOS SATA mode set to Compatible (this disables the Intel graphics card which does not appear anymore in lspci, http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Nvidia_Accelerated_Graphics_Driver), only default kernel parameters, and using either nouveau or nvidia drivers: The plasma widget for screen brightness (inside battery monitor widget) is able to change the brightness. And automatic brightness change from KDE system (when the power adaptor is unplugged) works also. In Raring, the hotkeys do not trigger any change (see bug #1225067) but this is fixed in Saucy.

2013-12-20 13:38:22 penalvch description It used to work with the workaround suggested at http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness which modifies asus-brn-down.sh to use the "setpci" method. But I had forgotten that workaround and I suspect that upgrading to Raring removed my modified scripts. So, in the original description of the bug, I thought it was a regression. But it's probably not a regression as the brightness control has apparently never worked off-the-shelf. Not working neither with linux-image-3.9.1-030901-generic_3.9.1-030901.201305080210 from http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.9.1-saucy/ Hotkeys are detected, showkey -s: Fn+F5: 0xe0 0x4c 0xe0 0xcc Fn+F6: 0xe0 0x54 0xe0 0xd4 I also attach the results from tests described on https://wiki.ubuntu.com/Kernel/Debugging/Backlight. Test with acpi_backlight=vendor: - on 3.8.0-20.31-generic, no change. But echo 8 > /sys/class/backlight/intel_backlight/brightness makes the screen dark, moreover /sys/class/backlight/intel_backlight/max_brightness = 2583660 - on 3.9.1, no brightness change but the KDE notification pops up with only 3 levels (0, 53, 100%) Test with video.use_bios_initial_backlight=0: - on 3.8.0-20.31-generic, no change. WORKAROUND: On KDE Raring Ubuntu 3.8.0-30.44-generic, bumblebee removed, BIOS SATA mode set to Compatible (this disables the Intel graphics card which does not appear anymore in lspci, http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Nvidia_Accelerated_Graphics_Driver), only default kernel parameters, and using either nouveau or nvidia drivers: The plasma widget for screen brightness (inside battery monitor widget) is able to change the brightness.
