Hi, I have used this program long ago on windows and it had worked perfectly fine but this is my first time trying it on linux and it seems to not work.

I've searched how to fix this error in countless websites and still do not know how to fix this problem.
When I download the binary from releases or run it from source code (after installing the requirements) and run it, this is what I get:

sqd@sqd-aspire:~/imd$ ./imd-gui 
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: vkkhrdisplay, minimalegl, eglfs, vnc, xcb, wayland-egl, linuxfb, wayland, offscreen, minimal.

Steps to reproduce:

Method 1: Using the binary

Download the tar.gz file for linux from https://github.com/TeamTernate/infinite-music-discs/releases/download/v1.6.2/imd-gui-linux64.tar.gz
Extract the archive using tar -xvf imd-gui-linux64.tar.gz
Make the imd-gui file an executable using chmod +x imd-gui
Run the executable using ./imd-gui

Output:

sqd@sqd-aspire:~/imd$ ./imd-gui 
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: vkkhrdisplay, minimalegl, eglfs, vnc, xcb, wayland-egl, linuxfb, wayland, offscreen, minimal.

Aborted (core dumped)
sqd@sqd-aspire:~/imd$

Method 2: By running the source code
Shell: bash 5.1.16
Python version currently installed: 3.10.12

Clone the repository using git clone https://github.com/TeamTernate/infinite-music-discs.git
cd into the newly cloned folder cd infinite-music-discs
Create a virtual environment python3 -m venv .venv
Activate the virtual environment source .venv/bin/activate
Install the requirements pip install -r requirements.rc
Finally, run main.pyw python3 main.pyw

Output:

(.venv) sqd@sqd-aspire:~/imd/infinite-music-discs$ python3 main.pyw

No way, I spent HOURS searching for this problem and when I look at source code I noticed PySide6 was being used. I searched PySide6 xcb on google and I found the solution to my problem! Literally seconds after posting this issue!

So for anyone having this problem like me, my solution was to install libxcb-cursor0.

apt install libxcb-cursor0

And its fixed! It works properly on both the binary and source code and the GUI shows up now without any errors.
