Hello. I am using xfce4 on my laptop with an Intel LVDS screen.
The brightness is controlled through 3 files in /sys/class/backlight/intel_backlight, named actual_brightness, brightness and max_brightness.
The brightness can be controlled by writing to these files. But these files do not exist if xfce4-power-manager isn't installed. So it seems I need this package (or an equivalent in another DE) to be able to set a decent brightness.
What I don't undertand is how these 3 files are created. AFAIU, sysfs is a pseudo-filesystem managed by kernel and kernel modules, but xfce4-power-manager doesn't install any module. I doubt I could create these files from userspace, and I don't even dared to try.
I guess somebody has the explanation. Didier _______________________________________________ Dng mailing list [email protected] https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
