2 years ago Hello @Rummell , I'm quite late, but did you solved the problem? Currently I'm trying to run Phy on Kubuntu 21.10 and saw the same problems, but only in Wayland-Sessions. When I switch to X11 phy works normally. In RedHat Linux 8 the default display server is also Wayland, what might explain your problems.
Does anybody successfully managed to run Phy in a Wayland session?

2 years ago It seems our issue was related to missing library files necessary to run PyQt5 that are required for phy2b5. And not a X11/Wayland problem for us.
We were able to determine which library files were missing using the commmand:
ldd ~/anaconda3/envs/phy2b5/lib/python3.9/site-packages/PyQt5/Qt5/plugins/platforms/libqxcb.so | grep -i "not found"
Then were able to install the missing library packages using
yum
In the end, I was successfully able to install phy2b5 using the suggested environment.yml file by @grahamfindlay in Issue #1138
Many thanks for the help!
When running with the lastest Anaconda 3 and Linux RedHat 8.1, on a fresh phy environment install, I have a problem trying to launch the GUI.
Following advice from Issue #875 unfortunately did not work. i.e. Installing pyqt from anaconda instead of pip ( conda install -c anaconda pyqt)
The error msg I got after running export QT_DEBUG_PLUGINS=1 beforehand was this:
Got keys from plugin meta data ("xcb") QFactoryLoader::QFactoryLoader() checking directory path "/mnt/pns/home/anaconda3/envs/phy2b5/bin/platforms" ...

This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.
Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
Any help would be greatly appreciated..
