/usr/lib/x86_64-linux-gnu/dri/nouveau_dri.so is related to your graphics drivers.

Can you try reproduce the problem using alternative graphics drivers?

Hello,

it seems that it crashes in the old openGl-based custom user interfaces. Do not use them anymore, and try to use the Qt-based custom UIs.

Cheers

Hi,

I experience the same crashes with identical error messages.
how can I switch my graphics drivers in this scenario?

Regards

Hi,

my coppeliaSim 4.0.0 instance on Ubuntu 18.04 crashes nearly every 3 minutes with this error message. How can I switch the used graphics drivers as recommended by @fferri?

Regards

Nick

Search what drivers are available for your graphics card. Some cards have more than one.
