Autoload support for Lenovo Y400 #64

Closed fizzy-logic closed 10 years ago

fizzy-logic commented 11 years ago

I added the following line to nvidiabl-laptop.sh: NVIDIABL_DECLARE_LAPTOP_MODEL("LENOVO", "9523", PCI_ANY_ID, NVIDIABL_AUTO, NVIDIABL_AUTO, NVIDIABL_AUTO),

I'm so glad to now be able to adjust the screen brightness. Thanks!

One other thing, the fn keys and brightness plugin for xfce will adjust the backlight but will only go set it from 0 to 15 when the max is 127. Am I right in thinking that it's the xfce4-power-manager that is incorrectly determining or using the max brightness and not the fault of this driver?

As a side note, I had to temporarily change the interface in the nvidiabl source to nv_backlight since that one is recognized by xfce. I have a bug report in to xfce so hopefully they will add nvidia_backlight to their interface list soon.

You could try the workaround by adding a few scripts for the acpi events from the brightness keys. Similar to those already in https://github.com/guillaumezin/nvidiabl/tree/master/scripts/etc/acpi.

You might want to disable the xfce4 backlight controls afterwards by adding the two flags "change-brightness-on-key-events" and show-brightness-popup" to xfce4-power-manager via the Settings Editor. Assign both of those the value "false". This way you won't have an brightness indicator, but get the controls to work as intended.

Thanks bahro! Got the scripts going and disabled those xfce4 settings disabled with xfconf-config. Things are working well now.

Thank you, I added your laptop in version 0.81. I agree: xfce4 implementation if buggy...
