I searched the forum and i didn't found answer, so i decided to create a new topic. My lap is Acer Aspire 5750g with nvidia gt520m on Debian 7.4. So i installed bumblebee-nvidia and nvidia-glx. When i'm starting POL normally everything is OK, only game (Blur) is in slow motion, but when i'm using optirun, apear message that i don't have 32-bit libraries, and game (the same) is not running at all. What kind of pack or whatever should i install?
