Could not load the Qt platform plugin "xcb" in "/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms" even though it was found.

[Codechilla]

I'm on PopOS based on Ubuntu 22.04. Been getting the below error after running 'python ct2_main.py', no matter what solution I try. Any idea how to resolve this? Google and ChatGPT have not been helpful? Thanks in advance.

Updated cpu quantizations in config.yaml to: ['float32', 'int8_float32', 'int8']
Updated cuda quantizations in config.yaml to: ['float32', 'int8_float32', 'float16', 'int8_float16', 'int8']
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/usr/lib/x86_64-linux-gnu/qt5/plugins/platforms" 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: vnc, offscreen, wayland-egl, minimalegl, linuxfb, vkkhrdisplay, wayland, minimal, eglfs, xcb.

I've never see that message before. I'll look into it.

It's hard to help without knowing which troubleshooting steps you already took. Check this link out and let me know if it helps or maybe it's a good starting point:

Thanks. That's basically the same thing ChatGPT told me, although some some differences, so I tried your instructions with no avail. I'm going to install a Linux distro with KDE desktop to see if the it has the same issues with Qt. I will let you know if it works.

It worked right away on MX Linux with KDE.

Hmm...I'll close this out for now but feel free to post another issue if something crops up.

SOLVED: I ran ‘QT_DEBUG_PLUGINS=1 python ct2_main.py’, and fed the output into ChatGPT, who then said to run ‘sudo apt-get update’ and ‘sudo apt-get install libxcb-cursor0’ which installed a missing dependency.

Great, I'll make a note of it and possibly update my installation instructions!
