Hi Arnbjorg (or is it Arnbjørg?),
thanks for registering and reporting your issue. Many people use MegaGlest on various versions of Ubuntu fine, so this issue is most likely related to your specific computer.
If the problem persists, please provide all the information we need, as described in the pinned topic
READ THIS: How to report and fix issues in this forum. For example, the following information is currently missing:
* What is your exact Ubuntu version?
* Where did you download MegaGlest from / how did you install it?
* What is the exact error message?
Please provide us with the unabbreviated error message. You can run MegaGlest from a terminal window to get this. If you need help with this, let us know.
At this point, all we know is that an OpenGL error occurred. This is often caused by drivers or hardware which do not meet the system requirements of MegaGlest (see the README file). Please make sure your computer does provide all that's neccessary to run MegaGlest. If you need help with this, let us know.
