====== Dinamica GNU/Linux - Frequently Asked Questions ======
In case Dinamica EGO crashes, fails to run or gives any other problems, you can check this FAQ for more information.
\\
====== Compatibility ======
Dinamica EGO is compatible with Ubuntu Desktop, version **17.10**. It may run on other distributions, but they are not supported officially, please refer to [[dinamica_linux_compatibility|Dinamica EGO GNU/Linux Compatibility]] for more details.
====== Dinamica EGO won't start ======
If you are running Dinamica EGO from the graphical interface, try to run the application in the console first. If you receive "Segmentation Fault", check [[dinamica_linux_faq#Segmentation_Fault|this]].\\
If you are running Dinamica EGO from the console and receiving a different error, you can reach us in the [[https://groups.google.com/forum/#!forum/dinamica-ego|Dinamica Google Group]].

====== Segmentation Fault ======
Dinamica EGO shows "Segmentation Fault" when running, how should I proceed? When the messages shows just before running the application, it means your system is not supported. We advise Linux users to stick with supported distributions. Please refer to [[http://csr.ufmg.br/dinamica/download-stable-linux/|This page]] for a list of supported distributions.

====== Wayland Not Supported ======
Wayland is a new protocol that replaces X.org in Ubuntu from 17.10 and newer versions. Wayland does not support Java yet and because of that, it doesn't support Dinamica EGO either.
To continue using Dinamica EGO with distributions that support Wayland by default, users must log in their sessions using the Xorg option.
On the login screen, there is a little cogwheel next to the login button. If you click that cogwheel, you will be able to select **Ubuntu on Xorg** instead of Wayland.
