Seems like you're running Wayland. Have you tried reverting back to Xorg?

My bad. You're right. All was fine. I was just using Wayland instead of Xorg.

On startup or in a specific usage situation?

It's on startup.

Have you tried reinstalling fslpy/fsleyes?

I've just tried reinstalling both fslpy and fsleyes. Get the following output when running fsleyes from the terminal:

Segmentation fault (core dumped)

On startup or in a specific usage situation?

Have you tried reinstalling fslpy/fsleyes? They might need a recompilation after a Python upgrade.

Hi,

I've recently started to get segfault errors when launching fsleyes. Not sure whether it's a problem with fslpy or fsleyes.

If you use the AUR fsl package, then FSL is installed in /opt/fsl. The corresponding variable $FSLDIR should be automatically set to that path via /etc/profile.d/fsl.sh.

Thanks @tobac. It works now. Do you know where to point fsleyes for $FSLDIR?

What you need is "fsleyes-widgets" from the AUR. It is a dependency of the "fsleyes" package so I'm not quite sure how you managed to install fsleyes without installing fsleyes-widgets ;)

fsleyes or fslpy appears to be broken on Manjaro. I get the following error when trying to launch fsleyes from the terminal:

Traceback (most recent call last):

pkg_resources.DistributionNotFound: The 'fsleyes-widgets>=0.8.4' distribution was not found and is required by fsleyes

I have tried installing python-distribution from AUR via yay but I still get the same error message.

It appears the fsleyes tarball fails sha256sums validation:

==> Validating source files with sha256sums... fsleyes-0.30.1.tar.gz ... FAILED fsleyes.png ... Passed fsleyes.desktop ... Passed ==> ERROR: One or more files did not pass the validity check! Error downloading sources: fsleyes
