I experience this issue as well. It happens with Ubuntu 14.04 when leaving the computer idle long enough for it to lock the screen due to idle timeout. It does not happen every time it goes idle, but every now and then. More often the past couple of months.
The only resolution that I know of is to do CTRL-ALT-F1, log in and do "sudo service lightdm restart", or to reset the computer, but such a resolution is fatal to all running applications and open documents. I also see others experiencing the same issue, for example in http://ubuntuforums.org/showthread.php?t=2214421. What other information is required in order to get this bug triaged? ** Changed in: unity (Ubuntu) Status: Expired => Confirmed ** Changed in: unity Status: Expired => Confirmed -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unity in Ubuntu. https://bugs.launchpad.net/bugs/1301125 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.
