After the upgrade from "etch" to "lenny" several weeks ago, xorg is
failing at various instances. It can't be intentionally reproduced. The
"error" message indicated looking at the configuration first before
filing a bug report; however, it ended with "fatal server error
lockup". I've reinstalled xorg, xserver-xorg and all dependencies; but,
it's still occurring. No error messages in the xorg log. I'm running it on a Thinkpad Z60t. Any
suggestions for a fix?
