After using these settings for a while, I have noticed one problem. The resolution changes to a very low resolution (so only about a quarter of the screen is visible) when the screen comes back on after the screensaver. I use Ctrl-Alt-F1, pause a bit, Ctrl-Alt-F7 to get back to the proper resolution. Sometimes this seems to cause the machine to freeze, but most of the time not. There is more confirmation of this in this forum post:

I haven't tried it yet, but it didn't work in previous versions of the trident driver: http://lists.freedesktop.org/archives/xorg/2005-November/011289.html -- Display is unusable with default settings https://launchpad.net/bugs/57862 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
