Ubuntu : 11.10 64-bit
I have ubuntu in dual boot with win 8. The following problem is intermittent.
After selecting ubuntu in the grub screen, a purple screen comes and after 2-3 seconds the display goes blank (where it should prompt for password).
So (after it happened 2-3 times), I just entered my password and surprisingly ubuntu music sounded and I was booted into it but the display was still showing nothing.
I don't know whether this is a problem with dual booting or with ubuntu itself. There is no problem when I boot into win 8.
Note : Sometimes the display works just fine (as I said earlier the problem is intermittent). It's pretty irritating.
