You could try to remove splash from the boot part: sudo nano /etc/default/grub and remove GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" splash from this line. –  Dr_Bunsen Nov 8 '12 at 9:29

Do you have a USB keyboard/Mouse/Wifi receiver? I had this same issue whenever I had my logitech wireless keyboard and mouse hooked up. The problem was fixed by removing it...

@Dr_Bunsen after removing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" the flickering time was reduced but still ther splash screen was flickering –  Droidmaniac Nov 8 '12 at 14:42

Put The following line instead of:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

in /etc/default/grub :

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"

Save it. And run sudo update-grub

It usually works.
