[Impact]
* FreeCAD crashes at startup in Ubuntu 18.04.
* Backporting the proposed fix will prevent FreeCAD from crashing.
* The proposed upload will fix the issue by providing an environment variable in the freecad.desktop file. This environment variable will set LIBGL_DRI3_DISABLE=true.
[Test Case]
* On Ubuntu 18.04 with a system where a video card or some form of graphics acceleration is used, install freecad and run normally.

[Regression Potential]
* An environment variable disabling LIBGL_DIR3 is set in the freecad.desktop file. The affected functionality is limited to the FreeCAD process and any child processes. |
