Hello @reaIws,
according to this post: https://askubuntu.com/questions/541343/problems-with-libgl-fbconfigs-swrast-through-each-update
it looks like a problem on the drivers side or some linking to a proper library. There are a few other solutions posted on the net, I hope you will find one that will work for you.
