I have installed league of legends using PlayOnLinux and used the following guide.
http://www.sysads.co.uk/2014/06/install-league-legends-ubuntu-14-04/
Everytime I start a game the screen goes black, then goes back to normal with the following error.
"An unknown DirectX error has occured and League of Legends cannot start. Please make sure your video card is using the latest video drivers from the manufacturer."
I tried installing drivers for my video card using the following guide. But I still get the same problem.

I have tried editing the game.cfg file which determines if the game should go into full screen mode or not but everytime I edit the file a new game.cfg file is made by League of Legends and replaces the edited file that I made. Also the game.cfg file league of legends uses does not have all the data it normally has.
Game.cfg contents:
[General]
CfgVersion=4.17.233
I have tried changing the display settings to openGL, fbo, and different memory sizes since i'm not sure how much memory my integrated graphics card has.
I have tried installing some directx packages from a different guide I found as well as some wine libraries but that didn't work either.
I have installed windows 8 on this laptop and I managed to run League of Legends just fine so I know its at least possible to run league of legends on this laptop. Below are my laptop specs.
