Comment 37 for bug 106217

Thanks much for the advice. I did uninstall and reinstall the mentioned drivers. That alone does not seem to have fixed the problem, but perhaps it helped. While installing one of them, I noticed that it mentioned that I should run /usr/sbin/nvidia-glx-config.

I tried the "enable" and "disable" both, I don' t remember which order, and neither worked. I tried one or the other again, and X came up during boot! So I shut down and tried again, and the system locked. A reboot and X came up. Seems to be reliably coming up now.

I'm still thinking there's something unwholesome, probably in the nvidia driver, but I'm willing to leave it alone if it'll leave me alone.

Anyway, nvidia-glx-config seems to be part of the puzzle.
