Xfce4, black screen

So, I'm using XFCE4, and no display manager. To suspend a computer I use sudo pm-suspend. After latest Xfce upgrade, occasionally when computer wakes up from suspended state, there's just a black screen. Monitor is not turned off (back light still on), just nothing is displayed. No reaction to any keyboard command (Ctrl+Alt+Fn not working), the only option is hard reset.

Using journalctl (here: http://pastebin.com/F4SW9Ly3, `-r` was used, events are chronologically backward) everything seems fine to me. The only puzzling thing is that at the beginning it's reported computer is going to sleep, when this is log of waking up.

I'm using slock to lock the screen. Here are my power settings: http://imgur.com/4JsYyHg

Any ideas are very welcome.

Edit: I've replied to my own post, to BUMP.

Re: Xfce4, black screen

Ok, I've updated a title, this problem is not connected with suspend. Here's a new scenario:

I went out today, and just switched to another tty (Ctrl+Alt+F2), when I came back in an hour or so, the computer was responsive, I could type, etc... When I switched back to desktop (Ctrl+Alt+F1), the black screen appeared again, and I couldn't do anything anymore.

This looks a lot like `slock` behavior, but I have no lock application installed. Executing `xflock4` for example, does nothing.

Any ides?
