Monitor out of range

I was running a live cd and was getting monitor out of range on my old CPU with Samsung Monitor.
I browsed through the net and found several solution like adding vesa 800X600 or GRUB_GFXMODE=640x480 to the grub.
But none of these worked. Finally I found the solution and it is quite simple. Add "nomodeset" to the grub options.

If the grub boot command looks like this:

linux /vmlinuz-3.6.7-4.fc16.x86_64 root=UUID=0572d37f-cce7-4626-970d-e8d9b0fd5cc4 ro rd.md=0 rd.lvm=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8

Add nomodeset after vmlinuz

linux /vmlinuz-3.6.7-4.fc16.x86_64 nomodeset root=UUID=0572d37f-cce7-4626-970d-e8d9b0fd5cc4 ro rd.md=0 rd.lvm=0 rd.dm=0 KEYTABLE=us quiet SYSFONT=latarcyrheb-sun16 rhgb rd.luks=0 LANG=en_US.UTF-8

Press enter to boot.

It works for fedora/ubuntu. And should work for other distros as well.
