Hi all

I have played a lot Race the Sun on Ubuntu 14.04. After some update it stopped working. I supposed that it could be the OS so I have updated to 16.04 and the same problem. Race the Sun is not starting. There is a black screen one second and the desktop again. I have an Ati Mobility Radeon X2500 on a Core 2 Duo. As I have played this game on this pc without problem, could anyone help? Is an update of Ubuntu system causing the problem or is a game issue?

Thanks in advance
