Comment 4 for bug 282068

Am wondering if possibly relevant - are we all using ATI video hardware?

ATM this is working for me, but if I CTL-ALT-F1 - only, I get immediately bounced back into X.
Repeat the C-A-F1 and get a console login prompt. Do a C-A-F2 and don't get the bouncing behaviour - straight to the prompt. Weird.

Other things that may/not be relevant to a workaround - The ubuntu logo was getting garbaged during the boot process. So I switched via 'Startup Manager' to using '1024x768' for the display resolution with 16bits colour depth.
Otherwise, the default X resolution is 1920 x 1280.

I'm pretty sure the above fixes were post the problem going away; but .... possibly poor memory of events and sequences.
