I am running Karmic on my MacBook Pro.  Things run very smoothly overall, but I keep having issues with Xorg sucking up all available RAM.  A system that should be able to log months of uptime and I'm having to restart (at least X) at least once every other week (this baby has *lots* of RAM).

After poking around I noticed that the RAM gets consumed largely after
switching on Compositing.  Since Compositing is configured to turn off
and on when I plug in and unplug the laptop, and when suspending, this
can use up over a GB of RAM.

This boot, Xorg started off using ~200MB of RAM (first time I checked
it).  After a switch off and on of Compositing (Alt-Shift-F12 in
Kubuntu), Xorg now climbs to ~400MB.  Another switch off and on and I
was at ~480MB, then 495MB, after another switch I'm at 581MB.  If I
don't switch off and on Compositing, Xorg RAM usage sits still.

Thank you for all your great work, guys.

Matt

When switching composite / compositing mode on or off, Xorg uses many MB of RAM which it never releases in Karmic
