Problem with OpenGL Drivers [Ubuntu 22.04]

Hi everyone,

I am trying to install Phy on Ubuntu 22.04.1 on an AMD/ATI Mobility Radeon HD 5430 graphics card. I haven't been able to launch the GUI due to the following errors:

$ phy template-gui params.py 
16:34:03.753 [W] model:655            Skipping spike waveforms that do not exist, they will be extracted on the fly from the raw data as needed.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
libGL error: MESA-LOADER: failed to open radeonsi: /usr/lib/dri/radeonsi_dri.so: cannot open shared object file: No such file or directory (search paths /usr/lib/x86_64-linux-gnu/dri:\$${ORIGIN}/dri:/usr/lib/dri, suffix _dri)

libGL error: failed to load driver: swrast

Failed to create OpenGL context for format QSurfaceFormat(version 2.0, options QFlags<QSurfaceFormat::FormatOption>(), depthBufferSize 24, redBufferSize -1, greenBufferSize -1, blueBufferSize -1, alphaBufferSize -1, stencilBufferSize 8, samples 0, swapBehavior QSurfaceFormat::DefaultSwapBehavior, swapInterval 1, colorSpace QSurfaceFormat::DefaultColorSpace, profile  QSurfaceFormat::NoProfile) 
Aborted (core dumped)`

So the main problem seems to be failure with creating an OpenGL context. I tried updating the drivers and the mesa-util package, and that got me to this error:

$ phy template-gui params.py 
18:02:20.322 [W] model:655            Skipping spike waveforms that do not exist, they will be extracted on the fly from the raw data as needed.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

libGL error: failed to load driver: swrast
Segmentation fault (core dumped)

I tried updating the drivers by updating the mesa-utils library (which seems to be an open-source OpenGL implementation for Linux). I also managed to locate the packages and tried setting a symbolic link and adding the path the libraries are in to the 'LD_LIBRARY_PATH', none of which worked.

I got a suggestion to force Phy to use software rendering instead of hardware acceleration:

export LIBGL_ALWAYS_SOFTWARE=1

This managed to get rid of one of the driver errors, but the other one is still a problem (and this also didn't fix the broader issue). So this is the current error I'm getting:

$ phy template-gui params.py 
19:06:50.685 [W] model:655            Skipping spike waveforms that do not exist, they will be extracted on the fly from the raw data as needed.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.

libGL error: failed to load driver: swrast
Segmentation fault (core dumped)

If anyone has any suggestions on what I could try next, it would be greatly appreciated!

Start by reproducing phy template-gui params.py on Ubuntu 22.04 with the reported AMD/ATI Mobility Radeon HD 5430 setup, then inspect the Mesa and OpenGL environment described in the logs. No repository file or test is named; done would mean the GUI launches without the reported OpenGL context failure or segmentation fault.
