Hello dear, I request you all please guide me how to resolve this issue.
I dual booted my pc and created the ubuntu and windows as separate OS. Thereafter followed the guidelines and installed the Desmond (Desmond_Maestro_2023.2) in Linux OS but I encountered with the problem.
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: linuxfb, minimal, offscreen, vkkhrdisplay, vnc, xcb.
Fatal Python error: Aborted
I request you all please guide me how to resolve this issue.
Here are a few steps you can try to resolve the problem:
1. Verify Qt installation: Make sure that the Qt libraries are properly installed on your Ubuntu system. You can do this by running the following command in the terminal:
````
sudo apt-get install libxcb-xinerama0
```
2. Verify environment variables: Check if the necessary environment variables are set correctly. Specifically, the `LD_LIBRARY_PATH` variable needs to include the path to the Qt libraries. You can check the current value of this variable by running:
````
echo $LD_LIBRARY_PATH
```
If the variable is not set or does not include the path to the Qt libraries, you can add it by editing the `.bashrc` file in your home directory. Open the file using a text editor and add the following line at the end:
````
export LD_LIBRARY_PATH=/path/to/qt/lib:$LD_LIBRARY_PATH
```
Replace `/path/to/qt/lib` with the actual path to the Qt libraries on your system.
3. Reinstall the application: Try reinstalling the Desmond Maestro application. This can help ensure that all necessary files and dependencies are properly installed. Make sure to completely remove the existing installation before reinstalling.
4. Update graphics drivers: Outdated or incompatible graphics drivers can sometimes cause issues with Qt plugins. Try updating your graphics drivers to the latest version available for your system. You can usually do this through the "Additional Drivers" or "Software & Updates" utility in Ubuntu.
5. Try a different Qt platform plugin: If the above steps do not resolve the issue, you can try using a different Qt platform plugin. You can set the `QT_QPA_PLATFORM_PLUGIN_PATH` environment variable to specify a different plugin. For example, you can try using the "minimal" plugin by running the following command before launching the application:
````
export QT_QPA_PLATFORM_PLUGIN_PATH=/path/to/qt/plugins/platforms
```
Replace `/path/to/qt/plugins/platforms` with the actual path to the Qt plugins directory on your system.
If none of the above steps resolve the issue, there may be a compatibility problem between Desmond Maestro and your specific Linux distribution or version.

hi Danish Iqbal
You're facing a Qt plugin loading issue preventing Desmond from running in Ubuntu. Try these steps: 1) Set QT_DEBUG_PLUGINS=1 for detailed error, 2) Reinstall Qt libraries, 3) Launch with alternate plugins like linuxfb, 4) Check for conflicting libraries, 5) Contact Schrödinger support if solutions fail.
Hello! I would like to ask if you have resolved this problem? I am currently facing the same issue and I am lost on how to get through this. Thank you!
