Hi Henrique, Thanks for the update. Is there anything else that 2.6.25 will provide, or is telling it not to handle brightness the only improvement? If that's all, I don't see how that's an improvement over what I'm currently doing by not loading video.ko. I still won't be able to change the backlight outside of X, and acpid/gnome-power-manager still won't be able to manage it. Also, is ibm-acpi-2.6.git the right thing to get to test these improvements? Or linux-acpi-2.6.git, or...? > If you have problems getting the brightness key events, you can load > video.ko, then unload it. > > > Unfortunately, that's independent of the hotkeys and > > gnome-power-manager knows nothing about it.

So my solution for now will likely be an ACPI handler that sees this hotkey, does some ugly trick to find my X display and Xauthority file, and runs xbacklight to increase/decrease brightness. Unless you're suggesting that the load/unload video.ko might have had some other effect? -jim ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
