Cannot run Unity on Ubuntu, stuck at recent screen.

Code (CSharp):

1. mono profile = '/opt/Unity/Editor/Data/Mono/lib/mono/2.0'
2. Initialize mono
3. Mono path[0] = '/opt/Unity/Editor/Data/Managed'
4. Mono path[1] = '/opt/Unity/Editor/Data/Mono/lib/mono/2.0'
5. Mono path[2] = '/opt/Unity/Editor/Data/UnityScript'
6. Mono path[3] = '/opt/Unity/Editor/Data/Mono/lib/mono/2.0'
7. Mono config path = '/opt/Unity/Editor/Data/Mono/etc'

I have the above unity log that is a bit hard for me to understand.

It says it cannot find node from what I can gather but 'node' is places right next to the 'npm' file at '/opt/Unity/Editor/Data/Tools/nodejs/bin'

Also what does 'Failed to establish GPU channel' and 'Running without renderer sandbox' mean?

Thank you.

 

https://forum.unity3d.com/threads/dark-grey-screen-fix.448936/ here is the fix

 

Thanks for that LevonRavel! I was having the exact same problem and that fixed it.

 

no worries
