I don't know, if this one helps, or is even a correct additional info: I believe, that this freeze here (blank screen with just mouse pointer) happens, when I touch the touchscreen during the initial parts of the resume process. I've learned to keep my fingers off the screen directly after resume, and it seems, that since then, this problem has been less often.

Often (also about 50% of the time) switching over to a text terminal and killing "unity-panel-service --lockscreen-mode" causes it to snap out of it and prompt me with the unlock dialog when I switch back to X.
