Comment 46 for bug 307306

Some additional information on my problems reported in comment 33: (which, to recap, are that gnome-power-manager still stimulates Xorg into using excessive CPU with the patches applied, but not as excessive as without them, and that the CPU usage stops after a while)

I turned off autostart of g-p-m in gnome-session-properties and instead ran it manually as 'gnome-power-manager --no-daemon --verbose' so that I could capture its logging. I am attaching the result. Of particular relevance, note that in the logs there is a gap of 2 minutes 26 seconds in the log timestamps at line 86 of the file - it is during this interval that the CPU usage is occurring. If the log output is anything to judge by, it looks like g-p-m may be blocked waiting on Xorg during this time. Once this situation unblocks, a HUGE quantity of various gpm_brightness_xrandr_* calls are logged.
