CubeMX2 v1.1.1 freezes at startup

I have an older v1.0.0 installation that works fine, but the newer v1.1.1 freezes up on launch and does not respond to mouse or keyboard input.

This is caused due to issues with nvidia nouveau drivers. Workaround is to run cubemx2 inside a VM.

Hi ​@G5658 

Unfortunately, I’m not able to reproduce the issue on my side. I suggest performing a full uninstall and reinstall of v1.1.1, 

If the issue still persists after that, please let me know and I’ll be happy to continue investigating.

Regards,

Sara.
