Display unresponsive after inactivity

I do not have gnome-screensaver or gnome-power-manager installed, just the default fedora21 desktop. Question does not seem to be a duplicate of question #62432.


When the display shuts off due to inactivity, the system (or just the display?) becomes unresponsive. No key or mouse combinations will work. My display remains in power-save mode (as if no input). I can wake the display manually and choose the source input, but the monitor eventually goes back to power-save.

I believe it's actually the whole system that is unresponsive because no key combinations create disk-access noise. I have to power-fail the tower to restart.


My display is connected HDMI to GeForce 8400GS 1GB PCI Express 2.0 Video Card, no proprietary drivers in use. I am using the default lock screen image with no custom wallpaper or screensavers.

$ cat /etc/redhat-release ; uname -a
Fedora release 21 (Twenty One)
Linux 3.17.8-300.fc21.x86_64 #1 SMP Thu Jan 8 23:32:49 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

Solutions attempted

  • Random key combinations to include Ctrl+Alt+Delete.
  • Dragging the mouse up (for screen unlock)
  • For now, I have disabled the power-saving and screen lock (privacy) settings

After some research and experimentation, problem only exists when the timer threshold is reached in the power saving settings.

Submitted as bug#1185597

Changing the Gnome Settings > Power > Power Saving > Blank Screen to Never fixes/avoids the problem.

I have the same problem, but with fedora 26. When i lock the screen, or if i'm inactive, or logout the current user the screen turns off and only a reboot helps. turning off the power saving only fixes half the problem as i want to lock the screen manually
