As a new Ubuntu user I've tried several distro's including Mint. Everything works except for my graphics card. The laptop has an GT 740M gpu which has Optimus. Now I've tried a lot of tutorials to the 'Cannot access secondary GPU' issue, including installing bumblebee, primus and a lot of other things including the linux headers. Ive also edited the .conf file changing the Driver= to Driver=nvidia-current method.I'm running 13.10
Nothing works, sometimes I get a black screen, sometimes nothing happens. But I always end up with the same error:
[ERROR]Cannot access secondary GPU - error: Could not load GPU driver [ERROR]Aborting because fallback start is disabled.
when Using the lspci | grep 3D command I get: 01:00.0 3D controller: NVIDIA Corporation GK208M [GeForce GT 740M] (rev a1)
Opening my /etc/bumblebee/xorg.conf.nvidia I get:
Section "ServerLayout" Identifier "Layout0" Option "AutoAddDevices" "false" Option "AutoAddGPU" "false" EndSection Section "Device" Identifier "DiscreteNvidia" Driver "nvidia" VendorName "NVIDIA Corporation" # 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 came across this issue when I tried installing Dead Space 2 using PlayOnLinux. It kept giving me the error that my laptop didn't meet the required specifications.
Remember, I've tried a lot of tutorials and google and nothing worked, so if anyone could give me a detailed explanation and fix in such a way I can understand; This is no longer an annoying issue, I want seriously want to know how to properly troubleshoot and fix these kind of problems ;)
Thanks a lot in advance!
