Comment 37 for bug 1283938

Confirming this on a desktop machine, Intel(R) Core(TM) i5-2500K with built-in Intel graphics and no additional video card at all.

Suspend/resume was working just fine on 13.10. After upgrade to 14.04 suspend still works, but upon resume the screen is blank. The only way to get it back is to go to a text console and force-kill X so it respawns.

I'm running KDE as my desktop, in case it matters.
