I get the same problem after resume under Xfce, unless the screen is 
locked. The mouse cursor seems to see windows, as its shape changes when 
I move it, but I don't.

I got to a text console, set $DISPLAY and launched xkill, in case the 
black background have been a window of some software. No effect (I 
probably killed a random application).
I then sent the lock command to the screen saver. It took over the 
screen, I unlocked it, and I get back my screen with visible windows.
So adding a hook to lock screen to /usr/lib/systemd/system-sleep and 
/etc/pm/sleep.d avoids the problem for me most of the time, even if that 
doesn't really solve it.

I don't know whether Gnome screen saver will do the same for you, 
neither the command to activate it, but it's worth to try.

I will answer for me: Advanced Micro Devices [AMD] nee ATI Radeon RV250 
[Mobility FireGL 9000] (rev 01)
(It's quite an old beast. On a more recent laptop with more or less the 
same configuration for the system, I don't have the same problem.)

All of them.

I works as described. On the other hand, suspend from systemd doesn't 
even success to suspend this laptop. Only hibernate works (with the 
famous black screen when waking up).

Tried pm-suspend --quirk-radeon-off with no more success.
