Hi, can anyone give me a rough estimation of the level of sysfs support for setting backlight brightness on common hardware compared to xrandr?
They are two totally different things.
Basically, xfce4-power-manager has a bug in the xrandr backend making it crash on resume (https://bugzilla.novell.com/show_bug.cgi?id=707127, https://bugzilla.xfce.org/show_bug.cgi?id=7851) and since upstream is unresponsive I'm wondering what the cost/benefit of temporarily disabling the xrandr backend would be, ie. whether disabling the xrandr backend and relying exclusively on the sysfs backend would break brightness manipulation for a large number of users.
xrandr should be using the sysfs interface the kernel exposes, if it is present, otherwise, it might try to use some other interface, but it should always be trying to use the sysfs one if it is there. greg k-h -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
