Comment 35 for bug 98783

I'm seeing a very large X process.

I have an ATI x1600 ("ATI Technologies Inc M56GL [Mobility FireGL V5200]") on a Thinkpad t60p (2007-AD1).

X typicaly uses right around 1GB of virtual memory - but xrestop shows a /total/ of 120MB in pixmaps in 61 clients - compiz has about 22MB, as does Firefox 3.0.17.

X info:

X.Org X Server 1.6.0
Release Date: 2009-2-25
X Protocol Version 11, Revision 0
Build Operating System: Linux 2.6.24-23-server i686 Ubuntu

xorg-server 2:1.6.0-0ubuntu14 (<email address hidden>)

Here is pmap output from /usr/bin/X only showing those entries larger than 1024KB - anon is only 33% of the total on my system:

Hope this helps. Please let me know what else I can do. I'd love to have X run in just 300MB at this point (though, yes, 50MB would be oh-so-nice).

Many, many thanks to anyone who can help.
