Dear All,
I just wanted to make you aware of a possible issue + solution:
Short version:
In case you start Zandronum 3.0 and get this error on Ubuntu 16.04:
no available video
then the solution is to go to your usr/local/lib folder and then delete the sdl related files as administrator (root user).
Background information:
If you start a terminal, you can check which SDL version you have:
dpkg -l | grep sdl
And using this command, you can remove SDL:
sudo apt remove libsdl*
But there will be files that may have not been deleted.
To see where these files are stored you can run:
sdl-config --libs
I hope I helped someone with this information,
Best Wishes!
