Nvidia Optimus Hell

[Atmmac]

I have been spending days on getting optimus running on my Dell XPS 15 (2012 Model). I have had it up to here. I am running bbswitch with bumblebee and nvidia-drivers-331.13 on kernel 3.10.7-gentoo-r1. The intel card is working great but once i hit an optirun glxgears i get the following

I have tried everything here...https://forums.gentoo.org/viewtopic-t-959568-postdays-0-postorder-asc-start-0.html

Each time i create a xorg.conf get a display cant be found when starting X with .xinitrc. If use KDM and modify Xsetup with xrandr i get a flashing cursor.

I had everything working great with bumblebee and primus in debian but unfortunately I am out of energy and have finally forced myself to give in and post here...

If someone could point me in the right direction it will seriously make my week.


Thanks!

Nvidia Optimus on a Lenovo Y580 suggests trying an older kernel

I think going to an older kernel would work. Just seems like I should be able to get it to work on my current kernel since it is stable. Any other thoughts?
