Visual problem on Ardour 5

I’m french and just install ardour 5.
I install it with kxstudio depot on XUbuntu.
Before i’ve Ardour 4 with no problem.
But now i’ve a visual problem. When i load or create a session, no fader volume appear. In the Console i don’t see VuMeter or Fader.

How can i resolve it ?
Anyone an idea ?

Thanks for help.

You would need to provide a screenshot so that we can see what you’re talking about.

Problem is found. I’ve “unlink” editor and mixing windows and i see fader and vu meter.
