"I installed Ubuntu 8.04 hardy heron from alternate cd. Everything was ok.
But after first reboot after installation it stopped on blank screen.

Step-by-step:
1. power on;
2. grub, selecting "Ubuntu 8.04, kernel 2.6.24-16-generic";
3. system is starting, ubuntu logo with loading progress bar;
4. when progress bar is about 99% complete, screen blink;
5. for about 2-3 seconds blinking "_";
6. black blank screen;

7. cannot switch to text console with ctrl+alt+f1
7a. i guess i have switched to text console because even i'm not seeing anything i log in like blind and when i press ctrl+alt+del, after some time ubuntu shutting down progress bar appears and it's going to 0%

I'm using ubuntu since 5.04 and i have the same problem on 7.10 but i haven't solved it and i was still using 7.04 :/
