Hi, when I launch ISAAC Sim from Omniverse, I see a black screen for a split second before it disappears. And then nothing happens. See attached video [link](https://youtu.be/6QW6SaTbcqg).

Omniverse Launcher.log gives

```

I have NVIDIA-SMI 460.84, Driver Version: 460.84, CUDA Version: 11.2, 2x GeForce RTX 3080  
Install on Ubuntu 18.04, with ROS Melodic and installed ISAAC SDK 2021.1 (Sim, SDK and Omniverse are all fresh installs). ISAAC Sim 2021.1 was installed from Omniverse \> Exchange, ISAAC SDK was installed from official zipped file. Both without errors.

If you tell me how I can provide you with more information to solve this problem, let me know. Thanks

It appears that you ran IsaacSim from the Omniverse Launcher, which should have brought up a secondary launcher window that offered several options, including ‘headless’. Is that how it went, and if so, are you running ‘headless’ here? Do you have any older versions of IsaacSim installed on this machine?

It’s just a black window for a split second, no Isaac options, no headless.

I tried to install the Sim two weeks ago from a bash script file, but that did not work for me (I think my Cuda version 11 was too high?). The install through Omniverse launcher is fresh.

After I wrote this post, I notice that installing and launching other omniverse apps ends with the same error. It is probably an omniverse issue rather than an Isaac one?

I keep digging. I found that in this log found within Kit/Isaac-Sim there are also Fatal errors, namely:

@ucabds6 a few questions to see if we can get to the bottom of this, can you paste the output to the following commands:

- `nvidia-smi`
- `vulkaninfo`
- output from running isaac-sim directly

```auto
cd /home/dennisushi/.local/share/ov/pkg/isaac_sim-2021.1.0/
./isaac-sim.sh

```

- and also running without a gui window

```auto
./isaac-sim.sh --no-window

```

Ah, interesting, can you plug your monitor into the other GPU and try running?  
By default omniverse uses the first GPU it finds and based on the nvidia-smi output you are running your monitor on the second GPU.

Is there a way to force it to use the other GPU? I tried plugging it in but there was no display signal found, not sure if this is a bad sign.

Yes, you can add a  
`--/renderer/activeGpu=1` when running isaac-sim.sh to specify which gpu is active.

You can verify that its set when kit starts and you see this section, the active gpu should change to the second.

```auto
|---------------------------------------------------------------------------------------------|
| Driver Version: 460.84 | Graphics API: Vulkan
|=============================================================================================|
| GPU | Name | Active | LDA | GPU Memory | Vendor-ID | LUID |
| | | | | | Device-ID | UUID |
|---------------------------------------------------------------------------------------------|
| 0 | GeForce RTX 3080 | Yes | | 10486 MB | 10de | 0 |
| | | | | | 2206 | 7fc00bb0.. |
|---------------------------------------------------------------------------------------------|
| 1 | GeForce RTX 3080 | | | 10486 MB | 10de | 0 |
| | | | | | 2206 | 2e96eabb.. |
|=============================================================================================|

```

Can you try this and see if it works? I can try getting my hands on a dual gpu machine to find the correct fix othwerwise.

Hi, I can confirm that doing this launches ISAAC! Thanks a lot! I guess I have to figure out what’s wrong with the other RTX if I want to launch from the launcher in the future?

Is there a way to specify the GPU for OmniKitHelper as well?

So no? I’ve seen the documentation. But running it in non headless mode (headfull?) breaks for probably the same reason the Sim was breaking? So I need to somehow specify to run it on the other GPU I assume?

yes, correct. you need to specify the active GPU with the method that Hammad proposed.

Hi, just wanted to answer my own question:

OmniKitHelper according to the link you sent does not list GPU selection as an option, however it is there! I needed to pass `"active_gpu": 1` in the config and it started successfully. Perhaps the [documentation](https://docs.omniverse.nvidia.com/py/isaacsim/source/extensions/omni.isaac.python_app/docs/index.html?highlight=helper#omni.isaac.python_app.OmniKitHelper) can be updated to reflect that this is an option?

Sorry about that @ucabds6 , docs for 2021.1.1 went live last night and active\_gpu is documented there now.

Hi, I have been running okay like this

`cd $ISAAC_SOURCE_LOC && ./isaac-sim.sh --/renderer/activeGpu=1'`

I would like to know if I can specify in the omniverse GUI launcher to use the GPU=1 somehow.

Yes. In the Isaac Sim App Selector, enter the flag in the “Extra Args:” text box then click START.  
`--/renderer/activeGpu=1`
