Corruption in Power Manager or XGL Desktop?

XGL, among other things, historically can mess up Power Management, Gaming
(slow drawing/low FPS), and much more along those lines. I'm pretty sure the
X1100 is supported by the new ATI drivers, which you don't need to use XGL
for, and can simply flick on compositing in a normal environment (AIGLX).

Bryan,

I've removed "xserver-xgl" and I can now launch the "GL Desktop" with just 1 double-click instead of 2; however, the power management issue persists. Is there anything else I need to uninstall? I have "compiz" installed; but I think it's necessary to set advanced Desktop effects.

Oh, and BTW, how do I flick-on compositing?

Thanks, John

More info:

When I uninstalled xserver-xgl I lost the ability to use that nifty 3D rotating-desktop effect to change desktops. Well, I think that's what caused it. I didn't lose that ability right away; I uninstalled one or two other compiz related components and one of these other ones may have done it as well.

I know there's a compositing bit in the xorg.conf file; but setting this to "1" doesn't seem to do anything or perhaps I need to remove some other component first before this will work. I'm lost without a map.

More info:

I located the file /home/john/.gconf/apps/gnome-power-manager/timeout/%gconf.xml; it's contents are as follows:

<?xml version="1.0"?>
<gconf>
        <entry name="sleep_display_battery" mtime="1198943250" type="int" value="1500">
        </entry>
        <entry name="sleep_display_ac" mtime="1198943243" type="int" value="1500">
        </entry>
</gconf>

The file /home/john/.gconf/apps/gnome-power-manager/%gconf.xml is empty.

When I launch System/Preferences/Power_Management and alter the "Timeout Slider Bars," the contents of this file are indeed changed; however they have no effect on the system, when running "xserver-xgl." It appears that Power_Management is reading some kind of "startup" configuration file, when xserver-xgl is running, very much like how the environment variables are setup immediately after install. It seems to me what's necessary is just a couple lines of code to force Power_Management to read %gconf.xml, while xserver-xgl is running. I suspect this was changed in the xgl configuration script. Another option would be to install an "xgl specific" Power_Management utility that's invoked whenever xserver-xgl is running.

Anyone have any thoughts on his?
