I've yet to replace a failed power supply, so this is hypothetical for me. However, when I switched from Fedora to Gentoo I experienced some screen flcker/static, and was directed to <http://www.gentoo.org/doc/en/xorg-config.xml>.
It now occurs to me that I could capture what, for example, knoppix is doing. Just thought I'd share this idea :) -Thufir -- gentoo-user@gentoo.org mailing list
