libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib64/dri)

I need to use a molecular visualization system – pymol. After upgrading to fedora 32 (beta), libGL errors start to emerge and pymol’s graphics ceases to function properly. Here’s the error information:

libGL error: MESA-LOADER: failed to open iris (search paths /usr/lib64/dri)
libGL error: failed to load driver: iris
libGL error: MESA-LOADER: failed to open swrast (search paths /usr/lib64/dri)
libGL error: failed to load driver: swrast

Please help! Thank you.

So… anything on this?

Had the same issue with QtCreator installed via Toolbox.
I solved the error message installing mesa-dri-drivers,
It removed the message, but the application still does not launch …

Fedora uses /lib64 and /usr/lib64, not Debian’s /lib and /usr/lib. My guess is, the app is looking for drivers in the wrong place.

You might try using LD_PRELOAD_PATH, or doing something like libGL error: MESA-LOADER: failed to open iris.
