After hours of searching I just couldn't find a decent answer to the problem I am facing with my system, so I'm hoping one of you guys could help me out here.
I have an Asus N76VM laptop with nvidia GeForce 630M (drivers installed from nvidia, version 319), 8 GB ram, 2,5 GHz x4 intel i5, with Ubuntu 12.04 LTS installed.
Every once in a while and it seems completely random to me, the screen freezes. The solution to this problem was pressing ctrl+alt+f2 after freezing, followed by ctrl+alt+f7.
Now this solves the problem for me, but I am looking for a more permanent solution and I was hoping one of you guys could help me out with this.
Thanks in advance,
Ok, so after searching a lot on the web for this issue, it seemed that the amount of people reporting this issue was almost as large as the different problems causing the freezing screen issue. I tried a lot of things to make it go away and ended up with a system that didn't function how it should any more.
I completely reinstalled Ubuntu 12.04 LTS but this time without the Nvidia drivers. As expected there were no screen freezes anymore and everyone was happy.
Now I want my Nvidia card to run sometimes when running programs that need more graphic processing power. I stumbled across Bumblebee and installed everything according to https://wiki.ubuntu.com/Bumblebee
After this I still received the following message when I type ¨optirun glxspheres¨ in the terminal:
[ 2019.967042] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected.
[ 2019.967105] [ERROR]Aborting because fallback start is disabled.
For this problem there are just too many solutions, and n00by as I am, there is no way to get my head around this to solve it properly. I did install the latest kernel version as my last attempt to solve the problem.
Can someone please help me with just the nvidia/bumblebee issue? I'm searching the net and trying sollutions for the past 5 days now and itś starting to give me headaches.
