Graphics overload CPU

BTW, running Gnome, mostly....................

I was going to include some screenshots of 'top' and 'System Monitor', but couldn't figure out how.

Running System Monitor rails the CPU.  It sometimes crashes XFCE.  Scrolling 'man' pages is jerky.  Sometimes I don't get a login window - I get about 4 very colorful vertical bars and then a blank screen.  But this also happened once w/ Ubuntu.  In Ubuntu, when running System Monitor the CPU runs around 25%-30%.  In Archy it's 100%.   /var/log/Xorg.0.log looks normal.  .xsession-errors has errors, but the only thing relating to video is this:

** (nautilus:3893): WARNING **: Unable to add monitor: Not supported

What/where/when does nautilus evaluate my monitor?

Here's my xorg.conf.

The computer is an old Dell Inspiron 2.4GHz, probably w/ minimal graphics memory.  But I got 1,256MB of ram, and it only uses 160MB.

from 'lspci':

00:02.0 VGA compatible controller: Intel Corporation 82845G/GL[Brookdale-G]/GE Chipset Integrated Graphics Device (rev 01)

Have to use the 'intel' driver because the 'i810' only gives me 800x600 resolution.

Is a 'memory leak possible?  How would I detect it?

Am I missing some program that I need to download, or have I downloaded too many?

At this point I'm totally clueless.  Hope somebody has some ideas.  It would be greatly appreciated.

Thanks in advance,
