Splash screen flickers during every boot

Splash screen flickers heavily during boot on my dell inspiron N5010 laptop,but disappears after some time by press Esc button(several times)..This happens everytime I boot... The problem exists in all linux-distros currently on ubuntu 12.10 64 bit... My laptop doesnt hav any dedicated graphics card but oly intel hd 3000

I hav enclosed boot.log,Dmesg.log ,Xorg.log and my system info respectively

Boot.log
Xorg.log

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...

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.
