Segmentation fault (core dumped)

I'm using a laptop. I have Nvidia RTX 2060 (mobile) graphics card. I installed nvidia-driver-535 because my graphics card does not support the 525 version recommended in the documentation. (I checked here https://www.nvidia.com/en-us/drivers/). For this reason, when I run Autoware, I get a Segmentation fault (core dumped) error and AWSIM shuts down. It is recommended to install nvidia-driver-525 as a solution, but as I said, I cannot do this. Does this mean I can't work on the computer? I would be happy if you help.

Hi @hamitkoculu

Please check how much GPU memory your Nvidia RTX 2060 (mobile) has (nvidia-smi command). From my experience, the Segmentation fault (core dumped) is likely caused by insufficient GPU memory available.

First of all thank you for your reply @lchojnack,

This is the output of nvidia-smi command:

I am asking just to be sure, It's not possible for me to work with this graphics card, right?

From what I see you have around 6 GB of GPU memory, so it should be possible to run AWSIM and Autoware.

This is my nvidia-smi when running AWSIM and Autoware, so it takes around 6 GB so you are close to the limits.

What you can try to do:

If your laptop has internal GPU, then you can select prime-select on-demand which means only intensive tasks will be used by NVIDIA GPU, as AWSIM and Autoware. In that case, gnome-shell will use internal gpu.
From the Unity Editor you can select very low quality. Edit->Project Settings->Quality then select Very Low. Also from the same settings page, you can reduce Texture Quality to Eighth Res

From what I see you have around 6 GB of GPU memory, so it should be possible to run AWSIM and Autoware.

This is my nvidia-smi when running AWSIM and Autoware, so it takes around 6 GB so you are close to the limits.

My laptop has an internal GPU, but it is already disabled in the BIOS. This means I'm only using NVIDIA GPU. As you said, it is very likely that I am getting this problem with a sudden increase in memory usage since it is running at the full limit. Upgrading my graphics card seems like the only solution. Thank you for your information about your nvidia-smi. Best wishes, @lchojnack.
