[PATCH] compositor-fbdev: Wait and retry before failing on reconnect to the framebuffer

[nerdopolis]

Hi.

I sent 4 attempts yesterday. The first one was for a fix for the Framebuffer. That one I meant to review

The second one, I realized until too late that I was missing a closing ), so I sent the third one.
The third one I reapplied the patch, and recommitted locally with the wrong commit message from my clipboard...
...and didn't realize until too late.. so I sent the fourth one.

The fourth one, is what I mean to have reviewed, (as well as the first one). Sorry about the two extra patches

Thanks.
