I ran a standard update of my Kubuntu and now I am on 16.08.0 Yaix! I have the grey (blank) screen of death on my Project Monitor (Slash Clip Monitor).

I would like to downgrade to 16.04.3, but how to? Thanks.

Bonusinformation.

The same grey screen appears in Version 16.11.70 from the crazy beta kdenlive master.

Nor the 16.08.0 from the testing repository works. Hmmm.

Yosh, killed my nvidia drivers and killed my Kubuntu 15.10... I upgraded to xenial Kubuntu 16.04 and now everything works. This solves the grey screen of death! Yeeha.
