I haven't played for the last few updates. When I launched the game today it crashed on launch with the following error:

I'm using Ubuntu 15.04. Any other info needed just ask. Thanks.

Thanks for the error message, it's a problem with lwjgl in combination with xrandr. Do you have a TV connected to your computer?
Please try this: Rightclick on rising world in steam -> properties -> betas -> select "linux - Lwjgl xrandr fix" and try to run the game again. Eventually delete the "lwjgl.so" file in your game directory (steam/steamapps/common/rising world). Does it work then?

I running it on a Laptop but I have the laptop screen off and its displayed on a roughly 20" monitor. Using the Linux LWJGL beta option fixed the problem. Do I still need to delete lwjgl.so? Thanks for your help.

Glad to hear the nightly fixed the problem If everything runs fine now there is no need to delete the lwjgl.so file^^
