Mode setup is primarily establishing the screen resolution and also the deepness setting for the graphics card.

From Wikipedia :

Mode - setup can be carried out in kernel room or in customer room. Doing setting - setup in kernel - room is extra adaptable. Doing kernel - based setting - setup permits presenting a mistake when it comes to a deadly mistake in the kernel, also when making use of a customer - room display screen web server. Customer - room setting - setup would certainly require superuser advantages for straight equipment accessibility. So kernel - based setting - setup raises protection due to the fact that the customer - room graphics web server does not require superuser advantages.

From Ubuntu Wiki on Kernel Mode Setting :

Kernel setting - setup (KMS) changes duty for choose and also establishing the graphics setting from X.org to the kernel. When X.org is begun, it after that identifies and also makes use of the setting with no more setting adjustments. This assures to make starting much faster, extra visual, and also much less flickery.

If KMS were to fall short, I would certainly assume that X would certainly do its very own modesetting ; as opposed to having the kernel do it. Yet that could need you to first disable KMS. Even more details especially for various graphics gards can be located on the Ubuntu Wiki write-up I connected to eariler.
