For those of you old enough to remember the Li'l Abner comic strip, I'm beginning to feel like Joe Btfsplk, the hard luck character who had a small, dark, rain cloud perpetually hovering over his head.

I downloaded the latest 64 bit Ubuntu ISO and burned the image to disk. Booting from the DVD, it appeared to start, then went to a blank screen with a small icon at the bottom. After 5 or 6 minutes, I got tired of waiting and pushed the power button. Skipping some of the trials, it had apparently altered the boot order in setup to boot from the CD/DVD drive if there was something in it--not that I mind, I prefer that. anyway. If the DVD was in the drive it would boot from it and display some text options. One of the options said (approximately) run Ubuntu without installing.  I selected that option and pressed enter as instructed. Blank screen time.

I have an HP box with a Samsung Monitor (1920 x 1080).

First Knoppix, then Ubuntu. These used to be my sure fire, never fail distros.

FWIW, an old Ubuntu 9.10 (64 bit) CD loads & works fine in live CD mode.

I'd sure like to know what the problem is. Any suggestions gratefully accepted.
