What is i915.modeset=1 for?
Clash Royale CLAN TAG#URR8PPP
I'm running Ubuntu 13.10 and since I upgraded to kernel 3.12.8 (build from source, including ubuntu patches) on a ivybridge video, the boot spash screen was flickering and messing up.
So I googled around and tried adding i915.modeset=1 paramenter to grub (without really knowing what I was doing) and magically the spash screen was fixed and I also noticed a much smoother scrolling of window contents (e.g a web page in chrome).
So I just would like to know more about i915.modeset=1.

You are using whats called Kernel Mode Setting (KMS) to make sure that your Intel graphic drivers are loaded early in the boot process, therefore making the "fancy" boot screen display correctly.
Kernel mode-setting (KMS) shifts responsibility for selecting and
setting up the graphics mode from X.org to the kernel. When X.org is
started, it then detects and uses the mode without any further mode
changes. This promises to make booting faster, more graphical, and
less flickery

By setting i915.modeset=0 or nomodeset you would disble Kernel mode setting and instead let the X server handle the modesetting.
