John Saves My Ass

January 19, 2006 8:20 pm General

When upgrading to a newer version of Nevada b31, I forgot to backup my xorg configuration file. Normally this hasn’t been a problem because it’s generates a file in /etc/X11/.xorg.conf which I can copy over, and tweak where necessary. But it hasn’t this time, and power management regularly hoses the xserver to the extent that I have to do a hard reset.

Occasionally things go wrong when you hard reset, which is rather understandable really, and on consecutive booting into Nevada it would just reboot the moment I left the grub screen. This time I couldn’t figure out what I had to do and anything I did try was failing miserably. The horror stories of your machine going down before a major conference were becoming true. Fortunately John came in to save my ass with the following incantations – 

 touch /a/platform/i86pc/kernel/unix bootadm update-archive -R /a

Apparently updating the boot archive should take some time. Useful stuff to know.
