Re: [PLUG] Natty Narwhal

It won't help you this time, but I always set up systems with two alternate root partitions, either of which is bootable and fully functional. And yes, I do periodically reboot into the alternate root to validate and update it. On a PC with one disk, both are on the same disk with grub installed to boot into either. On a PC with two disks, they are on different disks, with grub installed on both - grub on each disk has a default to boot into the root on that disk and an alternate to boot the root on the other disk.

Before a dist upgrade, I sync the two partitions (or clone one from another) to make them identical (with the exception of course of /etc/fstab and /boot/grub/grub.cfg), boot and verify both and then upgrade the alternate. After a successful upgrade the former alternate becomes my new main partition.

Yes, it's a belt and suspenders approach, but disk is cheap and the extra 10-20GB is worthwhile insurance.

I accepted the upgrade from Ubuntu 10.10 to 11.04 (CN: natty narwhal), and now when I reboot, it hangs right before the splash screen displays. The upper 40% of the screen is distorted, and I see no text or any indication of boot progress. I tried to CTRL-ALT-F1, but I can't reach a command line. I'm still a *nix newb, so I'm not sure how to recover from this problem even if I did reach the CLI. I did create a backup image of my HD before I installed 11.04, and I found a bash script which I could run to recover the previous image if I could reach the command line. Any ideas?

I would prefer to retain the 11.04 upgrade if possible.Â

BTW, I've been having an issue with my NVIDIA proprietary driver after I installed some updates a while back. I'm not sure if this is related to my current problem, but sometimes when I ran updates, I was forced to uninstall, then reinstall this NVIDIA driver.....
