Cuda Toolkit and Bumblebee

English Hardware
1

Hi everybody,

I’m quite new to Opensuse and also to linux, but I’ve read a lot about it, so i decided i wanted to learn it from the ground. I’ve started this year with it, and now I’m having a problem with “Bumblebee and Cuda Toolkit”.

I’ve been reading a lot and for the bumblebee installation i followed the stepts from this site Smithfarm - the Brain: openSUSE 12.3: How to install ‘bumblebee’ for NVIDIA Optimus VGA . i’ve gotten it working, but then after i installed “Cuda toolkit” everything went wrong and i have not been able to solved it.

the output of lspci gives:

01:00.0 VGA compatible controller: NVIDIA Corporation Device 1058 (rev ff) (prog-if ff)
** !!! Unknown header type 7f**

but when i kill Xserver and then write **Xorg -config **it recongnized the drivers but it encounters a problem **“Number of created screems dpes mpt ,match number of detected devices”,**so I cannot start the Xserver with the new config file.

Looks like the Cuda Deployment Kit has added entries not recognized by xorg.conf.
You really don’t need a xorg.conf file in the newer distros as the xorg.conf has been deprecated.

login to console prompt and type:

su -

Then your

Type in:

cd /etc/X11/

Type in:

ls -a

and look for the xorg.conf file

Remove the file with the command:

rm -f xorg.conf

Then type:

shutdown -r now

This will restart your system and the X-server should be working.

IMPORTANT: Install Cuda from this repository by adding it to YaST http://download.opensuse.org/repositories/home:/jenewton:/cuda/openSUSE_12.3/

FYI The Cuda Linux Installation Guide:Getting Started Linux :: CUDA Toolkit Documentation

Thanks for your answer Remanator, but I’ve done that befor and there is no xorg.conf file like you said.

Instead of xorg.conf I think it is using the files inside xorg.conf.d/

-rw-r--r--  1 root root  835 Jan 28  2013 50-wacom.conf

but the device, monitor and screen files are all commented.
The bumblebee project has these files

linux-09lp:/home/Alejandro # ls /etc/bumblebee/ -l -a
total 32
drwxr-xr-x   3 root root  4096 Oct 17 20:03 .
drwxr-xr-x 125 root root 12288 Oct 19 16:20 ..

-rw-r--r--   1 root root  1380 Sep  6 11:32 xorg.conf.nvidia

and the bumblebee.conf is selecting the xorg.conf.nvidia file to load the drivers. But I don’t understand why it is not loading them at boot

Also, if I write:


linux-09lp:/home/Alejandro # lspci -v
...

So the kernel recognized the graphic card and drives, but then the bumblebee doesnt work correctly and


linux-09lp:/home/Alejandro # optirun glxspheres

I see the word Lenovo in your output, it may very well be that you don’t need bumblebee at all, as many of them can be switched, in the bios settings, to use intel only, nvidia only or optimus mode. So what’s your modell and what’s the complete output of /sbin/lspci | grep VGA?

6

You must have an entry that was added to one of the 50…conf files.

As a follow up to what hank_se said commented below… I’ve also read that Cuda can run separately without Bumblebee by changing the setting in your BIOS.

In addition nVidia is working on a driver that should be able to accommodate the Optimus driver in Linux.
The only problem is that they’ve not set a date on the release date.

Most likely next year.

My is a Lenovo Idepad U410, but on the BIOS I can only set it to Intel only or Optimus.

the output of /sbin/lspci | grep VGA is:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation Device 1058 (rev ff)

and here are all the conf files

though I didn’t understand what you meant by

That was a surprisingly useless MUX coming from Lenovo.
Wat’s the output of

ls -la /usr/lib/nvidia
ls -la /usr/lib64/nvidia

Also show us the content of /var/log/Xorg.8.log, use SUSE Paste as it is rather long.

I’m sorry hank_se, i was on a trip and i didn’t got the chance to do what you’ve asked.
Here is the output:

From the Xorg.8.log file:




  1.    871.317] (EE) NVIDIA(0): Version mismatch detected between the NVIDIA X driver and the
  1.    871.317] (EE) NVIDIA(0):     NVIDIA GLX module.  X driver version: 319.37; GLX module

  1.    871.317] (EE) NVIDIA(0):     driver.

This is what has to be corrected first of all to get bumblebee working, did you install the 319.37 driver from a repo or with a generic .run installer, the “hard way”? If “the hard way” you must in addition to uninstall it also reinstall the package xorg-x11-server.

11

i installed first the bumblebee project like it says here Smithfarm - the Brain: openSUSE 12.3: How to install ‘bumblebee’ for NVIDIA Optimus VGA

It was working, but then I installed the CUDA toolkit from the Nvidia repositories and everything went wrong.

So now first I have to remove all packages and reinstall bumblebee and then xorg-11-server?

12

If you downloaded the rpm from here https://developer.nvidia.com/cuda-downloads, I suggest you open up that repo in yast and uninstall the following packages: nvidia-computeG03,
nvidia-gfxG03-kmp-default or -desktop, nvidia-modprobe and x11-nvidia-nvidiaG03. Having done that I suggest you disable the cuda repo as some of the packages conflicts with packages in the Bumblebee repo. Then reinstall dkms-nvidia from the bumblebeee repo and xorg-x11-server. This should at least give you bumblebeee back, then we’ll see if CUDA also works.

13

Hi once again,

I made everything you’ve told me and had re-install the bumblebee like it says here

Smithfarm - the Brain: openSUSE 12.3: How to install ‘bumblebee’ for NVIDIA Optimus VGA

after that I installed CUDA like it says here

Cero y van Dos!!: Optimus Technology: Instalando CUDA Toolkit con Bumblebee Project en GNU-Linux (Ubuntu/Debian/Mint)

and I got everything working (at least, that’s what i think).
I say that because I’ve executed a program with CUDA code and it’s not doing what i expected. But maybe there is something wrong with my libraries.

I still got a problem when the system starts. I think that, when it tries to configure the monitors something goes wrong, but when I log in everything goes back to normal.
I’ll try to upload some images so you can understand what I mean.

Thanks for your help!

Would anyone recommend me some book or tutorial to understand better how Linux/opensuse initialized devices and load the drivers and also the Xserver?
