I'm running F22, LXDE spin, on a Beagleboard XM rev B, and if

I've also seen this happen when I tried to connect via x11vnc, even
though lxdm and X are running and x11vnc starts OK.
Also, I'm not getting any output on the HDMI port. I'm not getting any
HDMI output on F21 (with kernel 4.x) either now, but at least I can
connect via x11vnc (same setup I'm using on F22).
Both were yum/dnf updated today.
I did boot the reference Angstrom release with the board to make sure
the HDMI cable and TV were OK, and they are just fine. F21 used to work
a few months ago via the HDMI port.
Maybe try with a 4.1 kernel to see if the problem is improved/fixed there.
