We recently updated Solar Flux on Linux to add fixes for those who were unable to play due to an issue with nVidia graphics cards, and launching the game on older Ubuntu based distributions running an older version of glibc. Sincere apologies to those affected by these issues.
If anyone has any further issues, you can get in touch with us by either posting in the forums, or contacting us through our various social channels:
Or email us at:
Many thanks for your patience while these issues were caught, and fired in to a nearby sun! ;)
