Hello,

i am trying to get Nvidia Optimus work, which should be possible since version 319 of Nvidias driver package (x11-drivers/nvidia-drivers).

I've set up my graphic environment like written down here: https://forums.gentoo.org/viewtopic-t-959568-start-0.html
Of course I added the Bus Ids of both graphic adapters to the xorg.conf file.

Sadly the X-Server doesn't want to start. I get the "No Screens found" error message.

gr0sshirn,

Optimus is a graphics solution with 1 1/2 graphics systems.

Set up the Intel part of your graphics system first. Only the Intel graphics can both draw the image and drive the display.
The nVidia graphics chip has no connection to the display - hence no screens found. It can only draw in the pixel buffer. The Intel chip is needed to refresh the display.

Once the Intel part works, add nVidia support.

The "Intel part" is already working fine - it's how I use my Linux since i got this notebook.

gr0sshirn,

Good. Read /usr/share/doc/nvidia-drivers-325.15/README.bz2 chapter 33, for how to set things up without bumblebee.

The chapter 33 is from memory ...

I just set this up last night and there really are far too few clear answers on what's going on.

Your configuration is fine. The problem is your BusID is incorrect. You only need one for the nvidia card, and it should be BusID "PCI:1:0:0". Note how X uses a different id format than Linux.

Don't forget that you might not have a working screen once you start X because the nvidia card might not be configured to output to the intel card.
You'll need to put
Code:

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --auto

into your .xinitrc. Note that for some people the provider is called 'Intel' not 'modesetting'. You can always put
Code:
xrandr --listproviders > /tmp/a

in your .xinitrc, startx, switch to a tty, kill it, and see what the providers are.

Still no success. :(

I already had the xrandr lines in my .xinitrc.
I changed the Bus ID format and tried to replace the "modesetting" driver by "intel".

Any more ideas?
