I haven't tested locking, but it doesn't make a difference if it times out or I
use xset. I'm using lxqt (openbox+compton by default)
What makes a different is how I end X. If I kill X and start X unblanking/dpms
on usually works, if I end X (log out) and start x, the displays doesn't wake
up after dpms off.

I strip debugging symbols on this machine, but I can rebuild stuff if needed. I
did rebuild X, libdrm and ddx, do you need something else too?</pre>
