Can't open the simulator on unity #1374

Closed j-corvo closed 3 years ago

j-corvo commented 3 years ago

Hi,

Somehow when I git clone this repository and try to open it with Unity Editor 2019.4.18 on Linux, it starts loading and then closes without even opening the Unity editor. I've already tried to uninstall and install everything again but the "error" persists. Did anyone had this issue before? Are anyone able to help me with that? I want to build a map importing a point cloud and test it on the simulator but without it opening, I'm really stuck. Plus, if I start a new projection Unity Hub, the editor works just fine, but in that way, I cannot have access to the simulator capabilities.

Here is the link that I recorded if anyone didn't understand what's happening. https://www.loom.com/share/430baf409eb841f790ade1398e991594

Thanks for the help!

Please check that you are using a GPU to run simulator. If you can grab the player log it would help to debug

Thanks for the response!

How can I check if I'm using the GPU to run the simulator?

Here are the logs: logs1 logs2 logs3 logs4

Are you using Xserver? If so, is it using a GPU? Also, please include a txt file. No need to screen shot the log :)

j-corvo commented 3 years ago

I think I'm not using Xserver. The logs file is here. Sorry for the screenshots :) Editor.log

Gdk-Message: 23:42:32.018: Unity: Fatal IO error 9 (Bad file descriptor) on X server :1.

seems like it is trying to use x server and failing. This also looks could be errors trying to download unity packages. Do you have antivirus or company firewall blocking?

What GPU and kernel are you using? I recommend installing latest drivers if you can. @lemketron ?

I tried to change to the X.Org X Server but It does the same thing. image

No, I'm on Linux so I don't have an antivirus neither a company firewall blocking I think. I'm using an RTX2060 GPU and I have the latest Nvidia drivers. The kernel version is Linux 5.8.0-50-generic x86_64. image

What version of Ubuntu are you on? Do you have mesa drivers installed? @lemketron ?

j-corvo commented 3 years ago

Yes I have mesa drivers installed.

I'm using ubuntu 20.04 LTS.

EricBoiseLGSVL commented 3 years ago

you must uninstall mesa drivers. We have a few closed issues regarding this.

lemketron commented 3 years ago

Even if you have installed libvulkan, if you also have mesa-vulkan-drivers installed then that can cause problems.

Please take a look at the Player.log file from ~/.config/unity3d/LGElectronics/SVLSimulator/Player.log as there are often clues in that log file.

In particular, if you see "mesa" or "Intel" mentioned in Vulkan vendor or renderer lines rather than NVIDIA, then you might have "mesa-vulkan-drivers" installed. If so, then you can remove these with sudo apt remove mesa-vulkan-drivers.

j-corvo commented 3 years ago

Uninstalled mesa-vulkan-drivers and it worked!

Thanks a lot for your help!
