Hi,
can anyone give me a rough estimation of the level of sysfs
support for setting backlight brightness on common hardware
compared to xrandr?
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.
