I am still having issues with Ubuntu 18.04. I tried installing on a netbook and had the same issue. It seems to stop when booting. So not sure if this is an issue with the ISO file, or something else.
Anyway Lubuntu works fine, so I can go with that for now.
Oddly if I install warzone2100 it still isn;t working, however if I boot ubuntu 18.04 in to recovery it works fine, so this sort of narrows down the issue potentially to video drivers or something not being loaded on boot up.]
So to try and conclude
Ubuntu 18.04 LTS 64bit – boot normally – stops during boot
Ubuntu 18.04 LTS 64bit – Recovery – boots in to desktop fine, but with reduced drivers and other components Warzone2100 loads and seems to run
Lubuntu 18.04 LTS 64bit – boots fine but Warzone2100 loads then exits.
