In a shell I am able to export DISPLAY variable and unity --replace to
work around the problem.

Title:
  Lock screen after idle time freezes unity

Status in Unity:
  Confirmed
Status in unity package in Ubuntu:
  Confirmed

Bug description:
  Hello,

  I recently upgrade to 14.04. My system uses fglrx provided by 14.04.

  When I lock manually the screen, I get no problem. I can even sleep the system without problem. However,
  when the screen is locked by idle time, I cannot unlock it.

  At this point, I can see the screen but with some kind of translucent
  panel over it. Mouse also works. I tried to type blink the password
  but I had no luck. I only get a working system by going text mode
  (ctrl+alt+f1) and restarting lightdm. No dmesg or Xorg logs seems to
  indicate any error. The only strange log was in .xsession-errors.old:

  init: processos unity-settings-daemon main (2495) terminados com status 1
  init: processos gnome-session (Unity) main (2539) terminados com status 1
  init: processos unity-panel-service main (2572) terminados com status 1
  init: processos hud main (2536) terminados com status 1
  init: processo indicator-powermain (2740) morto pelo sinal TERM
  init: processo indicator-datetimemain (2741) morto pelo sinal TERM
  init: processo indicator-soundmain (2747) morto pelo sinal TERM
  init: processo indicator-printersmain (2748) morto pelo sinal TERM
  init: processo indicator-sessionmain (2768) morto pelo sinal TERM
  init: processo indicator-syncmain (2795) morto pelo sinal TERM
  init: processo update-notifier-crash (/var/crash/_usr_bin_istanbul.1000.crash)main (4987) morto pelo sinal TERM
  init: processos unity-panel-service-lockscreen main (7447) terminados com status 1
  init: Disconnected from notified D-Bus bus
  init: processos at-spi2-registryd main (2538) terminados com status 1

  But as it has no time info, I cannot tell when they happened.

  At least another user faces the same problem:
  http://ubuntuforums.org/showthread.php?t=2214421

  And this seems to be different from bug 1283938 as pm sleep/wake works
  as expected.
