Comment 5 for bug 532579

[SOLVED] My problem was somewhat different (see below), but the solution TJ suggested worked wonders for me. Thanks. :))

Problem: Having installed Linux Mint 9 LXDE on an elderly HP Vectra VL400 workstation (PIII 1GHz, 512MB RAM, 20GB HDD), the graphic UI was available, but my maximum resolution would be 800x600x60Hz and I had no 'xorg.conf' file in '/etc/X11/'. Querying with lspci returned the following adapter identification:

00:02.0 VGA compatible controller: Intel Corporation 82815 Chipset Graphics Controller (CGC) (rev 02)

Thus began my two day ordeal. After searching high and low, reading leaft and right, a lot of brow wrinkling, pencil sucking, and hair pulling, I was exactly where I started, with zero results. I saw elsewhere (http://ohioloco.ubuntuforums.org/showthread.php?t=1484137) how this predicament could be solved by installing the latest libdrm, which I did to no avail. I even tried building a new xorg.conf by hand, and failed miserably, attesting the real depth of my noobiness. The system wouldn't even start, so I had to launch the livecd to delete that xorg.conf...

But eventually that was the seed for the solution: after some more editing, including the Section "Module" suggested by TJ, I rebooted and everything automagically worked -- without further ado, I now have 1024x768x85Hz, which is rather more bearable to work with. So here's the healing xorg.conf:
