On a lenovo flex 2, which has been fully updated. There is an nvidia driver installed and the display manager has been changed to software. I seem to remember their being different options which used GPU based rendering when I first installed the beta. I also have the jre and josm installed, otherwise nothing much has changed.
I have looked at this thread and I tried the suggestions but didn’t help and the terminal error messages are different than that poster.
This is the output for both, ubuntu-mate-welcome --software-only
and ubuntu-mate-welcome --boutique
Xlib: extension "GLX" missing on display ":0".

Also installed and ran gnome-software
and tried to launch Hatari from the terminal with this with this out-put
Xlib: extension "GLX" missing on display ":0".
