Update: This is now solved. Thank you @Luis Alvarado for pointing out those guides and the PPA. I really appreciate it. I can now overclock with the new beta drivers.
I have an optimus system. HD4000 and NV 660M. Its an Asus G46vw notebook. I have the nvidia-prime package with NV 331.38 drivers installed. This works beautifully and I can play games at full speed with no signs of overheating.
With that said, last night I tried updating to the latest NV 337.12 beta drivers that got released a week or 2 ago. After updating and rebooting Xserver crashed. After that I purged the driver and installed nvidia-common and dependencies. I got my Unity back but was stuck at 640X800 resolution. So I just ended up reinstalling. I had backup and my / and /Home are on separate partitions anyway.
Is there any way to get the latest beta driver running on my optimus system. I really want this driver for the overclocking support. Please dont yell at me to not overclock a laptop. I overclock in Winblows 7 with a +300 OC +400 mem and +.062mv without even coming close to overheating. I know what my lappy can and can not handle.
