Recently Intel released their opensource driver tool (https://01.org/linuxgraphics/downloads/2013/intel-linux-graphics-installer) which auto-selects the right drivers for your intel chipset (in my case, I was using the i915 driver). Because I started using Steam on Linux to play some older games I thought I would use the Intel 'official' drivers to ensure I get the best performance. Unfortunately, since installing the drivers, the computer fan is very loud and the battery doesn't last that long (it's cut battery life in half). On top of that, there's no noticeable difference when playing games on Steam.
My question is, how do I revert back to the original drivers?
If I run the Intel graphic driver installer I get the following output in the terminal (not in the GUI) so I assume I will somehow need to run apt-get with some type of downgrade flag (I'm not sure how to do that) against these packages.
install: [i915-3.4-3.2-dkms libdrm-nouveau2]
upgrade: [libcairo2 libcairo-gobject2 libcairo-script-interpreter2 libdrm2 libdrm-intel1 libkms1 libva1 libva-x11-1 libva-glx1 libva-tpi1 libva-egl1 vainfo libxatracker1 libgbm1 libegl1-mesa libegl1-mesa-drivers libopenvg1-mesa libgles1-mesa libgles2-mesa libglapi-mesa libgl1-mesa-glx libgl1-mesa-dri libgl1-mesa-dri-experimental libosmesa6 libglu1-mesa i965-va-driver libva-intel-vaapi-driver xserver-xorg-video-intel libwayland0]
When I look at the install logs though, it seems there's much more than that.
Any assistance on this would be most appreciated.
