Using the 3rd version stable and with everithing gives me this error:

ficticta@ubuntu:/home/ficticta/Games/robombs$ ./Robombs.sh

I also modified the linux launcher. the sh is:

java -Xmx768m -Xms256m -Djava.library.path=lib/lwjgl-3.0.0/native/linux -cp lib/jpct/jpct.jar:lib/lwjgl-3.0.0/jar/libjgl.jar:lib/lwjgl-2.7.1/jar/lwjgl_util.jar:bin/bin.jar:. robombs.game.startup.StartUp

The same result if I do not include the lwjgl_util.jar (because in the 3rd version is not present in the .zip.

Any other suggestion to try?

I have the exact same problem. I'm using Ubuntu 16.10 and both machines one of them (with lowest specs) give this information at the beginning:

Java HotSpot(TM) 64-Bit Server VM warning: You have loaded library ~./robombs/lib/lwjgl-2.7.1/native/linux/liblwjgl.so which might have disabled stack guard. The VM will try to fix the stack guard now.
It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
Intel Open Source Technology Center-Mesa DRI Intel(R) Haswell Mobile /true/true/true/true/false

No input works once the game starts, no keyboard even to type the port or any other information to configure, and of course it is not playable. Only can see how robots play and how they kill you. The mouse works, but the character cannot be moved with it, only the camera and to put the bomb.

On the other machine

switched drivers no success - standard linux drivers even made it worse

installed several windows/desktop environments

got it working under

- Cinnamon - but only in software mode
- Gnome flashback Metacity
- Gnome flashback Compiz

Are there any other Linux users that can confirm that behaviour - still not sure if it is the desktopn environment or the gfx drivers.
