Hello everyone,
I've been using Houdini on Linux for about 6 months on Linux. Yesterday I reinstalled it ( dual boot with windows 10 ), and now I can't render with mantra, all it does is just a black window.
I tried with Windows 10 and it works quite well.
This makes me think the problem comes from drivers.
I'm using nvidia-driver-430. ( but i tried nvidia-driver-390 and nouveau from xserver-xorg-video-nouveau )

I also tried reinstalling licences and Houdini.

Does anyone has an idea ? Thank you all in advance.

Linux Ubuntu 18.04.3 LTS
AMD Ryzen threadripper 1920x
GeForce GTX 1060 6GB
Gnome 3.28.2

Okay I fixed it, it was something in my houdini.env file

HOUDINI_TEMP_DIR = “my_path”
