Hello, I am trying to get my NVIDIA video hardware to work properly with X. I am running Debian Testing, which I just installed a few days ago. I installed nvidia-detect using apt. I then installed Bumblebee using the instructions at https://wiki.debian.org/Bumblebee#Installation. I added my login user to the bumblebee grouop. However, attempting '$ optirun xorg -info' gives the following error:
[15211.548537] nouveau 0000:01:00.0: priv: HUB0: 10ecc0 ffffffff (1d40822c) [15211.140632] [ERROR]Cannot access secondary GPU - error: [XORG] (EE) No devices detected. I then attempted to manually define the BusID using according to the instructions at the above link by changing the /etc/bumblebee/xorg.conf.nvidia file to read as follows: Section "ServerLayout" Identifier "Layout0" Option "AutoAddDevices" "false" Option "AutoAddGPU" "false" EndSection Section "Device" Identifier "DiscreteNvidia" Driver "nvidia" VendorName "NVIDIA Corporation" BusID "PCI:01:00.0" # If the X server does not automatically detect your VGA device, # you can manually set it here. # To get the BusID prop, run `lspci | egrep 'VGA|3D'` and input the data # as you see in the commented example. # This Setting may be needed in some platforms with more than one # nvidia card, which may confuse the proprietary driver (e.g., # trying to take ownership of the wrong device). Also needed on Ubuntu 13.04. # BusID "PCI:01:00:0" # Setting ProbeAllGpus to false prevents the new proprietary driver # instance spawned to try to control the integrated graphics card, # which is already being managed outside bumblebee. # This option doesn't hurt and it is required on platforms running # more than one nvidia graphics card with the proprietary driver. # (E.g. Macbook Pro pre-2010 with nVidia 9400M + 9600M GT). # If this option is not set, the new Xorg may blacken the screen and # render it unusable (unless you have some way to run killall Xorg). Option "ProbeAllGpus" "false" Option "NoLogo" "true" Option "UseEDID" "false" Option "UseDisplayDevice" "none" EndSection I used 01:00.0 as the BusID because the output of # lspci | egrep 'VGA|3D' is: 00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06) 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 960M] (rev a2) This shows that the hardware exists. However, it is not being detected when I issue the following: # nvidia-detect No NVIDIA GPU detected. # lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation Device 191b (rev 06) Any suggestions? Thanks, Levi
