Yeah, it used to be X was involved in power management stuff but these days that functionality has pretty much moved elsewhere. Still, sometimes there's aspects of it that X is still involved in (which is why I asked, in case you knew something I didn't!)
As to a wiki, the best page I've found is https://wiki.ubuntu.com/DebuggingProcedures, although it's light on details about power management issues specifically. In general, with plumbing layer issues (like this) it can be tricky figuring out what package to file against; in fact I'm not really sure what part of the power management stack this should go to. I'm going to file it against gnome-power-manager (see https://wiki.ubuntu.com/DebuggingGNOMEPowerManager), but it may be something lower down. ** Package changed: nvidia-graphics-drivers (Ubuntu) => gnome-power- manager (Ubuntu) ** Changed in: gnome-power-manager (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in Ubuntu. https://bugs.launchpad.net/bugs/771561 Title: Screen Brightness Settings Do Not Stick -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
