* try to restart your machine. Seriously! :-) Sometimes, after updates to the graphical packages (those can happen behind the scene, without you to notice them), the system needs to be restarted. I experienced that personally: `gmex` was failing to start, when I was trying a new version of our 3D engine, Coin3D, and I was trying to find for the cause in the code of Coin3D itself... But then my OpenGL-accelerated terminal emulator, Alacritty, had stopped working as well; and that gave me a hint that something global was happening... So, I Googled, and I found a suggestion to resart the machine to get the graphics drivers sync between each others. Try that first, it can help! ;-)

### GMEX crashes on the latest Ubuntu
The GeoModelExplorer (GMEX) application appears to crash when run on the latest version of the Ubuntu "Wayland" window manager.
The problem is that the SoQt/Coin third-party packages we use in GMEX have not been ported to work to the latest Wayland yet. As far as we know, all applications that use the Coin/SoQt graphics layers as their graphics interface crash on the latest Wayland.
The Coin3D community is aware of the problem but there are no fixes, yet.
Therefore, we strongly suggest to use the alternative X11 window manager when running GEMX (or all other SoQt/Coin3D-based applications) on Ubuntu, for the time being.
