Black Graphics
Hi
Im using linux and i installed bumbeblee for my 520M Nvidia Graphic card, I installed Potals and set launch options as primusrun %command& then to optirun %command% and finally without any launch option. Whith all of these Launch Options configuration, Portal, and all the other games doesn't work properly.
Maybe the title isn't so much descriptive, so I will post a photo:
