No, there isn't. The only thing you have to do is to install one of the recent graphics drivers (which support CUDA 6). Other than that, you just have to unpack the archive and off you go.

Thanks Abstrax,

That's indeed what I've done but when I start Octane it dosen't find any GPU
The graphic drivers are not the last but recent enough, anyway I'll check to be sure they include CUDA 6.
Duno if this is relevant but my primary graphic card (for display) is the onboard one (Intel) ...

Hi enricocerica, I never got Intel GPU for display and Nvidia GPU for Octane/Cycles to work on my Opensuse linux. May it is a way on Ubuntu.
Start nvidia-settings in terminal to look if the Nvidia modul/driver is loaded.
Try to connect the display to the first Nvidia card, then the driver should be loaded.

Thanks mib2berlin,

I did that after disabling the onboard GPU in the Bios and indeed ubuntu starts and uses the Nvidia card and the drivers seems loaded but even in that situation I can't see any GPU in Octane.

Which Nvidia drivers are you using ? I tried with 331.xx and 340.24, if you use a newer one, could you provide any tips to install it, I tried to install more recent versions via the terminal as I had to stop X server but I had to reinstall ubuntu

I had an issue with the newer drivers in Linux Mint, it might be the same issue. I'm using the 331 drivers but I had to install the nvidia-331-updates to get CUDA. The recommended Nvidia drivers in Mint did not have the CUDA libraries built in so neither Blender or Octane could see the card(s). I'm not sure how to fix it in Ubuntu.

Hi, the latest driver from my Suse repository doesn´t work with Cuda too, I installed 340.24 from Nvidia.
How it work for me:

Log out from your xserver session
Open terminal with "STRG + ALT + F1"
Login
"su init 3" (May you don´t need this but it shut down the xserver for sure)
"su sh nvidia.driver.run"
Say yes to all
Restart

If the xserver doesn´t start you don´t have to reinstall Ubuntu, reinstall your old driver with "apt get install driver.xyz"
Find out these commands before you start, it is a risk to install a driver like this make sure your work files are save.

I too have had issues. Ubuntu 14.04 comes with open source graphics drivers, which don't work with Octane. Changing to the official Nvidia drivers in the driver manager resulting in an error during the install. And regardless, Octane 1.55/2.04 needs Nvidia drivers 332 onwards, so 331 won't work. I couldn't get the Nvidia official 340 drivers to install.

It is may needed to install:

dkms - Dynamic Kernel Module Support Framework

It install all dependencies to resource kernel header files, for example, to build kernel modules.
It is may easier to use a special ppa to install latest driver:

But on your own risk.

Thanks mib

I follow the instructions in your link - and there is plenty that can go wrong if you've already tried to unsuccessfully install drivers. However for other's reference - the top answer at http://askubuntu.com/questions/379504/p ... 3-10-64bit worked for me.

Octane Standalone now running in Ubuntu 14.04.
