8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in /sys/class/backlight
Hello, I report an issue, in attempting to follow the instructions at
https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream
[1.] 8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in /sys/class/backlight
[2.] The screen brightness control has apparently never worked off-the-shelf on this laptop, Asus UL80VT-A1, which is an NVIDIA Optimus laptop (2 graphic cards). The use of the discrete Nvidia card is managed by Bumblebee (https://wiki.ubuntu.com/Bumblebee). 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. Hotkeys are detected, showkey -s returns 0xe0 0x4c 0xe0 0xcc for Fn+F5 and 0xe0 0x54 0xe0 0xd4 for Fn+F6.
When the hotkeys are triggered, there is no brightness change but the KDE notification pops up with 3 or 4 levels.

Hello, I report an issue, in attempting to follow the instructions at
https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream[1.] 8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in
/sys/class/backlight[2.] The screen brightness control has apparently never worked off-the-shelf on this laptop, Asus UL80VT-A1, which is an NVIDIA Optimus laptop (2 graphic cards). The use of the discrete Nvidia card is managed by Bumblebee (https://wiki.ubuntu.com/Bumblebee). It used to work with the workaround suggested at
http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness
which modifiesasus-brn-down.shto use the "setpci" method. Hotkeys are detected, showkey -s returns0xe00x4c0xe00xccfor Fn+F5 and0xe00x540xe00xd4for Fn+F6.
When the hotkeys are triggered, there is no brightness change but the KDE notification pops up with 3 or 4 levels.[X.] Other notes

With v3.12, does the intel_backlight interface work?
You can verify this by echoing some value to the brightness file and see if it has any effect. The value can be echoed is 0 - max_brightness. Be careful with very small values, it will black your screen.
If it works, you can specify intel_backlight as the control interface for X by creating a xorg.conf file like this:
$ cat /etc/Xorg/Xorg.conf

Option "Backlight" "intel_backlight"
Identifier "Card0"

Wow, the issue was immediately solved by posting here. Thanks Aaron Lu!
After, (out of curiosity) what should be modified so that X automatically detect the correct control interface, in case of a new installation for example ? --

3 attach dmidecode output.
4 of those backlight control interfaces, which works and which don't. 5 attach /var/log/Xorg.0.log when you do not use the customized xorg.conf,
I want to know which interface is picked up by X driver by default.
Thanks,
Aaron

Hello, I report an issue, in attempting to follow the instructions at
https://wiki.ubuntu.com/Bugs/Upstream/kernel#KernelTeam.2BAC8-KernelTeamBugPolicies.Overview_on_Reporting_Bugs_Upstream[1.] 8086:2a42 [Asus UL80VT] Backlight control does not work with Intel integrated card, but there are entries in
/sys/class/backlight[2.] The screen brightness control has apparently never worked off-the-shelf on this laptop, Asus UL80VT-A1, which is an NVIDIA Optimus laptop (2 graphic cards). The use of the discrete Nvidia card is managed by Bumblebee (https://wiki.ubuntu.com/Bumblebee). It used to work with the workaround suggested at
http://wiki.daviddarts.com/Ubuntu_Maverick_on_the_Asus_UL30VT#Screen_Brightness
which modifiesasus-brn-down.shto use the "setpci" method. Hotkeys are detected, showkey -s returns0xe00x4c0xe00xccfor Fn+F5 and0xe00x540xe00xd4for Fn+F6.
When the hotkeys are triggered, there is no brightness change but the KDE notification pops up with 3 or 4 levels.[X.] Other notes

$ ls /sys/class/backlight/ acpi_video0 acpi_video1 intel_backlight$ cat /sys/class/backlight/intel_backlight/max_brightness 2583660$ cat /sys/class/backlight/intel_backlight/brightness 121584With v3.12, does the
intel_backlightinterface work?
You can verify this by echoing some value to the brightness file and see if it has any effect. The value can be echoed is 0 -max_brightness. Be careful with very small values, it will black your screen.If it works, you can specify
intel_backlightas the control interface for X by creating a xorg.conf file like this:Quoted 7 lines
$ cat /etc/Xorg/Xorg.conf Section "Device" Option "Backlight" "intel_backlight" Identifier "Card0" Driver "intel" BusID "PCI:0:2:0" EndSectionThe
intel_backlightinterface does work, by echoing a value between 0 and 2583660.
The control interface for X also works with that addition in/etc/X11/xorg.conf(Kubuntu).Quoted 4 lines
Wow, the issue was immediately solved by posting here. Thanks Aaron Lu! After, (out of curiosity) what should be modified so that X automatically detect the correct control interface, in case of a new installation for example ?
Please file a bug to https://bugzilla.kernel.org, choose ACPI-Power/Video category.
Please provide these information when filing the bug:
1 attach dmesg.
2 attach acpidump output.
3 attach dmidecode output.
4 of those backlight control interfaces, which works and which don't. 5 attach/var/log/Xorg.0.logwhen you do not use the customized xorg.conf,
I want to know which interface is picked up by X driver by default.
