 |
|
This problem is driving me crazy. I've tried to look everywhere for help, but I simply cannot make my backlight control work. I have all the time full light (thus is too bright in dark environment to work with and drops battery life dramatically).
My notebook is Toshiba Qosmio X770-11C ( http://uk.computers.toshiba-europe.com/innovation/product/Qosmio-X770-11C/1113133/toshibaShop/true/ ):

Right now I use nvidia-drivers-290.10-r1 with custom ebuild for nvidiabl-0.73 (just copied one for -0.72 that wasn't working either) on top of gentoo-sources-3.2.5.
Could someone please help me or give me any direction to look for?

Try adding this to your "Device" section:
| Code: | | Option "RegistryDwords" "EnableBrightnessControl=1" |
I've never used nvidiabl. The setting above seems to be all I need to get it working at the console or in gnome using the laptop brightness keys. gnome-power-manager picks up the brightness up key and not the down for some reason, and displays the brightness level overlay, and gets it wrong. But that seems to be harmless. |

Doesn't help. Still no action upon trying to adjust brightness.

I've moved to nouveau to try it.
It kinda works for this hardware, but still without any backlight control 
Nobody? |

Is ACPI_TOSHIBA set in your kernel?
I think for brightness control, you have to use toshiba_acpi module. It will only work, if toshiba supports linux for your machine.

"Unfortunately" I already have that update.
But there is certainly something in my BIOS that linux doesn't like.
Eg. keyboard backlight - kernel turns it off at boot. But when I shut down windows unclearly just before - it doesn't, so that backlight works 
But it's keyboard backlight - even after unclear windows shut down I cannot switch display brightness anyhow
[EDIT]
DEFINITELY there is something with kernel<->BIOS:
| Code: | vindor acpi_video0 # cat brightness
0
vindor acpi_video0 # cat max_brightness
7
vindor acpi_video0 # cat actual_brightness
7 |
shows up for each ACPI. I've set to 0 to check if actual will be updated. |

It started to work 
Just like that.
I've yesterday removed ACPI_TOSHIBA from kernel and uninstalled nvidiabl.
Than I've connected 2nd monitor, generated new xorg.conf via nvidia-settings, reloaded xdm and... my display dimmed! woah.
So it's as clean situation as possible, where at the beginning it wasn't working and now magically it started.
Couldn't explain - would really like to find out the reason it have started to work, so that others could benefit from it.
Any ideas where to look for?

You have just updated nvidia-drivers to version 295.20 from 290.10. That's why it started to work, I think.
