Use gpu render Linux

Hi guys! I have installed win7 64 and linux ubuntu 12.10 x64 in dual boot.
I have 2 vga: the first one is an old quadro 580, the second one is an gtx 560. I use quadro for viewport and 560 only for CUDA render in windows. But, blender on ubuntu don’t recognized the gpu (user preferences_system_only cpu displayed). How to run cycles with gpu on linux?

Hi, you need the nativ Nvidia driver for linux.
Default nouveau drivers don´t work with Cuda.

Cheers, mib.

This is my current settings. I try to switch the third option with the first one for gtx560. I have this:

[email protected]:~$ blender
connect failed: No such file or directory
Xlib: extension “NV-GLX” missing on display “:0.0”.
Ignoring Xlib error: error code 11 request code 154
Writing: /tmp/blender.crash.txt
Errore di segmentazione (core dump creato)

Xlib: extension “NV-GLX” missing on display “:0.0”.

It looks you don´t have graphics acceleration activated.
Nvidia driver installed but nouveau driver used.
Open terminal and type:
glxinfo |grep rendering
Result should be “direct rendering: Yes”.
I don´t know ubuntu very well maybe an other user can help here or ask in a ubuntu forum.

Cheers, mib.

if you want to use linux(ubuntu) for a longer time: 1-2 years or even more,
i would suggest go back to ubuntu-12.04

Ubuntu-12.04 is a LTS (long term) version, so you wont run into troubles
again for some newer versions and Ubuntu-12.10 will have update only for a few month.

In Ubuntu-12.04 you can check for new hardware-drivers
and if this check fails, because you have 2 grakas, then
you can install admin-software (like synaptic) and browse for the nvidia-driver.

I cannot post the
apt get xyz…
commandline, cause i need to check this again for the Ubuntu-12.04 system
(i did install the nvidia-driver with the gui-tool … )

But - like said - the main point is, better go back to the LTS-Ubuntu-version
or you may have to change such settings for any new big version update.

Ubuntu-12.04 LTS should get update for over 3 years (its said about 5 years)-

Might be that you have issue with 2 different nvidia drivers needed - one for 560 is running, but it’s found that Quadro does not support NV-GLX as it might be interpreted by error message; as a result nivea kicks in and drives Quadro.
Have no idea if 2 different nvidia’s drivers are possible in one kernel.
