Summary0004348: FreeCad will crash on startup if using X.Org Nouveau display driver
DescriptionIf my PC is running the X.Org Nouveau display driver FreeCad 0.19 will crash either seconds after displaying the main layout or latest if I'll try to create a new document. FreeCad 0.18 runs normally.

If my PC is configured for running the NVIDIA driver-440 metapackage both FreeCad 0.18 and 0.19 will run normally.
So there is an incompatibility between FreeCad 0.19 and the actual X.Org Nouveau display driver, introduced with version 0.19.
TagsNo tags attached.

No, seems to be solved. Meanwhile I have switched both the PC model and updated to Ubuntu 21.10. And there it works with NVidia drivers as should.
