cjano,

I did it! I do not know what I did ... I uninstalled everything and reinstalled everything and used the nvidia-current driver, strangely it worked again. hehehe

But thanks for the force. : 3

4.12 which reads: 12.04

Translation missing here, sorry.

Hello folks, after much searching, I have recourse to you. Next, I have a pc with the following characteristics:

Ubuntu 4.12 64-bit;
Graphics Card: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) and NVIDIA Corporation GF108 [GeForce GT 540M] (rev ff);
RAM: 8 GB;
Kernel: 3.4.31-030431-generic

What happens: Even with the primus optirun and installed, the games do not run. Even before I owned the steam64, but after a partial update of the system, where he withdrew that and put the steam: i386 and steam-launcher, the games simply do not work anymore, before that worked perfectly.

In attempts, thought to be the video driver, swapped the 304 by 310, with no success. You know what might be happening? Thanks and see you.
