Blender Octane V4 won't start on linux Tweet

[Synthercat]

Usually I get into this:

I just pressed ctrl+z on the blender to force Octane to start... if froze giving the message "Starting Octane engine"

Then I press ctrl+c on the terminal

I am running out of unlocks experimenting with this... arghhhhh I'll go back to my coding work and home that someone gives an answer quick on the mater as my last project does involve some 3d.

You really shouldn't start Blender with sudo, and you shouldn't have to. What this can do is all of the files that Blender creates, including the config files, or communicating with the server, will be owned by root. I think your best course of action is to uninstall everything, including cleaning out the ~/.config/blender/2.79 config files. You will probably have to do that with sudo as they might be owned by root. This also means that any files you have created with Blender will need their ownership permissions changed from root to your login.
Then reinstall as normal, it's confusing, but you have to use sudo to install, but not to run them.

I suspect that this might be your issue as the two might not be able to communicate if one is running as root and the other isn't.

I only used sudo when everything else failed... I agree with your assessment but unfortunately this is not the case.
I am now trying to install blender through the normal channel and see if maybe a stupid library missing allowed blenderOctane to run but still didn't allow it to connect.

Funny, I don't recall having to use sudo to install. But then again I tried it so many times since yesterday I stopped taking down notes about it. Do you think I should try sudo during the installation?

For the first time I managed to see an Octane screen (the one selecting the card on the first run) but nothing more after that.
What I did was :
1. Installed normal blender 2.79
2. removed blender configs and all files regarding blender-octane
3. Installed 4.05 blend-octane using sudo.

Now I realize NO lib was coppied to any /use/lib or /use/share/lib or lib64 etc
So pleeeeeeeeeeeeease can you find those libs in your system and tell me where the heck are those supposed to be located?!?
libgomp.so.1
libsenseEIV.so
libtinfo.so.5
libtbb.so.2
libfbxsdk.so
liboctane.so
octane.dat

Thank you for your time, effort, and positive vibes

Going one-by-one here is where I have the files installed:

/usr/lib/x86_64-linux-gnu/libgomp.so.1
/usr/local/OctaneServer/lib/libgomp.so.1

/lib/libsenseEIV.so
/usr/lib/libsenseEIV.so
/usr/local/OctaneServer/lib/libsenseEIV.so

/lib/x86_64-linux-gnu/libtinfo.so.5
/lib/x86_64-linux-gnu/libtinfo.so.5.9

/lib/libtbb.so.2
/lib64/libtbb.so.2
/usr/lib/libtbb.so.2

/usr/lib/libfbxsdk.so
/usr/local/OctaneServer/lib/libfbxsdk.so

/usr/local/OctaneServer/lib/liboctane.so

/usr/local/OctaneServer/lib/octane.dat

Hope this helps.
