Black screen - Xorg/GDM config - Nvidia Optimus? [solved]

Question

Hi!
I have a Samsung RC539 S09, which has got an Nvidia Optimus graphics card, I want a graphical Xserver on that machine. Therefore I followed the wiki and installed the Nvidia stuff (https://wiki.archlinux.org/index.php/NVIDIA). I did not configure anything jet. I also installed the Xorg stuff and kept the config default (https://wiki.archlinux.org/index.php/Xorg). Then I did nvidia-xconfig:
# nvidia-xconfig: X configuration file generated by nvidia-xconfig
# nvidia-xconfig: version 280.13 ([email protected]

My logfile says, that after successfully loading the modules, the failure occures at:
[ 591.812] (EE) No devices detected.
[ 591.812]
Fatal server error:
[ 591.812] no screens found

Please consult the The X.Org Foundation support
at http://wiki.x.org
What does that mean? - No devices detected - can refer to these Nvidia Optimus stuff, where there's some ondemand switching for graphics acceleration afaik. I'm not sure how to solve my issue. So at this point could need some help
Best,
wishi
edit: got this working with the intel stuff. Did onyone archive GPU support jet?

Answer 1

first at all check
lspci | grep -i vga
I have optimus and I see both cards, Intel and nVidia.
What do you see?
If you install xf86-video-intel instead of nvidia driver, does it work then? (backup & remove /etc/X11/xorg.conf then)
I had to disable optimus and switch to my dedicated nVidia graphics card  in bios in order to make nvidia driver work.
Now I'm using intel with bumblebee (optimus support for linux) & optimus enabled in bios, and bumblebee loads proprietary nvidia drivers when required.
But I also have a thinkpad t510, I don't know if bumblebee works with your device.
cheers, kulpae
