Hi David, while it's good to know if there are general issues with some Linux distribution (this doesn't seem to be the case here, G3D viewer works fine for me on Ubuntu 11.04), when you do, please make it obvious that they are not caused by the game, because we use this forum to get an idea of what needs yet to be fixed in MegaGlest. That's why I had labelled this thread [notabug] - what you're discussing is probably a bug, but it is not a bug in MegaGlest. If you agree that this is not a MegaGlest bug please say so or readd the [notabug] tag (or think of something else/better to indicate this issue is not caused by MegaGlest). Thank you.
