I recently installed the proprietary Intel drivers for my Toshiba Satellite A105 s4284 running Ubuntu 14.10. Nouveau was working just fine, I was just attempting to make it so that I was able to run CS:S (no need for explanation on that.)
Long story short, I went and downloaded the Intel Graphic Drivers for Linux* from here. After downloading and installing the .deb, I ran intel-linux-graphics-installer
which opened up a window that downloaded & installed the open Intel drivers. I then rebooted, and it's slow. Very slow, especially on 3D effects and when I hit Alt+Tab.
Now, I don't know if the previously installed Nouveau drivers are conflicting with these new Intel drivers (if that's the issue, what should I do about fixing it?) What I do know is that my system isn't behaving right and I want it to (obviously.) If removing the Nouveau drivers isn't the solution, how can I safely remove the just-installed Intel drivers?
Does anyone have any suggestions?

On some computers the new versions that are installed with the
intel-linux-graphics-installer
have those exact same issues, I had it happen with two netbooks so it dosn't seem to be a conflict between nouveau/intel but a problem with the newer graphics installed from Intel.First you need to remove the source that Intel installed automatically when you ran the installer. To do this go to Software Center → Edit → Software Sources → Other Software and uncheck the sources that have https://download.01.org/ in the address.
Next do a
sudo apt-get update
then we are going to follow steps from this post: https://askubuntu.com/a/405453/47291 do:And paste the following text:
