No Ubuntu Logo in splash screen while booting up

It seems this is a common problem. There are many questions regarding this problem even in this site, but all of them are related to Nvidia which is not useful for me.

I am running Ubuntu 16.04 64bit on my Lenovo 500G with a switchable graphic card. I have disabled switchable graphic from Bios. So I am on my intel built-in GPU.

I don't know since when, but it is for a while I am not seeing Ubuntu Logo in splash Screen while booting up. In grub, splash is mentioned. While shutting down, I can see the Logo.

This is the output of lshw:

  *-display

       resources: irq:25 memory:d0000000-d03fffff memory:c0000000-cfffffff ioport:3000(size=64)

Any idea what is the problem and how I can solve it?
