[Tutorial] How to fix slow performance on Fedora 22 (using Intel processors)

Are you having several performance issues after upgrade from Fedora 21 to Fedora 22? Do you have big delay when you start softwares like Firefox, Chrome and others? Are you experiencing system glitches and regular freezes?

If you had a notebook or desktop that runs on the top of Intel processors or GPUs and you're experiencing slow performance on Fedora 22, so this article can help you. If it doesn't work, check this question.

First of all, you need to remove all the following packages:

sudo dnf remove xorg-x11-drv-intel intel-gpu-tools libva-intel-driver

After that, just install the same packages again:

sudo dnf install xorg-x11-drv-intel intel-gpu-tools libva-intel-driver

This will probably solve all your problems with Intel and Intel drivers on Fedora 22. Hope it helps!
