Hello, I have a gnu/linux box (Linux myhost 2.6.33-ARCH #1 SMP PREEMPT Mon Apr 5 05:57:38 UTC 2010 i686 Intel(R) Core(TM)2 Duo CPU T7100 @ 1.80GHz GenuineIntel GNU/Linux) with Gnome 2.30 installed. My computer is a laptop SONY VAIO VGN-AR41L. The laptop uses an nvidia 8400M GT graphics card. I have successfully installed the nouveau driver (2D mode) instead of nv and all the other daemons like hal,acpi,pm-utils. The laptop can suspend when I close the lid or when I am pressing the "Suspend" button from the GNOME interface. The laptop has also two combinations for controlling the backlight . The Fn+F5 for decreasing and Fn+F6 for increasing. Now about my subject. When I am pressing one of the above combinations the GNOME shows a progress bar to notify that the user changes the brightenss and to show the amount of change, but the brightness does not change. I have found the reason and I want a help to find a solution. The reason is that the file /sys/class/backlight/sony/brightness is modified instead of /sys/class/backlight/nv_backlight/brightness. If I give an "echo command" '''a number between 500 to 1025''' and redirect the output to the /sys/class/backlight/nv_backlight/brightenss then the brightness changes accordingly. A temporary solution that I gave was to create a little daemon backlightd (which you can find in http://sourceforge.net/projects/backlightd/, the daemon was created when I had Fedora 12 but know I am having Archlinux and the daemon works) but I want a more permanent solution. I want to modify GNOME Power Management in order to do the same job for me and for the rest of the community of course. I don't know if this has to do with the GNOME Power Management or with ACPI,HAL or something else.
I am looking forward to hearing from you LD PS: I have sent the same email to power-manager-list but I didn't receive any answer. _______________________________________________ gnome-love mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gnome-love
