Description adam.pietrzyk93@gmail.com 2018-05-05 07:31:07 UTC
Description of problem:
The following problem is reported by the problem manager but the only problem that is seen is that for some time there is no video output on the external screen connected by the display port.
The used video card is AMD FirePro M2000.

To be noted:

I dont know if there is a connection between these facts, but I had to reinstall Fedora 28 with cinnamon desktop recently because Cinnamon was not able to start properly after booting. It was always crashing and going to failsafe mode. After the reinstallation the problem is not occuring.
