One of my Fedora becomes unresponsive if left idle for few hours, how to fix this?

I have set the power-options to never sleep or power-save in settings, and set it to use a screen-saver after 16 minutes. I have four Fedora 21's but this only happens on one and only after the last kernel update. Before, everything was smooth.

Description: I leave the computer idle for some hours and when I come back to it then the screen is turned off and I can't get it to respond to anything I do. I have to turn it of via the power button and restart.


The system is Fedora 21 64 bit with all updates and kernel-3.19.1-201.fc21.x86_64

My hardware is: an old HP dc7700cmt with upgraded memory 4G and an new hdd WDC WD3200AAJS Western Digital 300G


This is still happening, started to happen two day's ago and many times tonight while I've been listening to music, the system becomes unresponsive(first few times I could log in via ssh and reboot with this command:

shutdown -r now

but now just like when I posted this question, I can't reboot and have to shutdown via the power button for restart......... really anoying as I'm only trying to do some math and listen to music(only using the system for music).....

Any Idea's?


This is still happening, once every 24 hours, when the system is idle except sometimes Amarok running playing music.... Fedora goes to sleep or something and I can't wake it up, the monitor is black and no reaction to user input. I can ssh into the system but only 1 out of 6 times can I reboot the machine from there, usually I have to power off with the power button.


This is still happening as of kernel-3.19.3-200.fc21.x86_64. Really annoying. System is totally unresponsive and I have to use the power button to shutdown/reboot.

Done! I'm not sure why it was closed, because it's about the current version of Fedora. Before closing this again, please add a comment explaining why.

Do you have a solid state drive, by any chance? I have the same problem, and I am trying to figure out if it is related to that. I am also trying this

@alfC I've updated my question with the hardware info.

I think I fixed it, not the problem as such but I re-installed Fedora 21 and the problem has not re-appeared in three days. I'll update the answer when I know for sure.


This was fixed by re-installing Fedora 21. This hasn't happened since. Today is 26 April 2015. Also note that I suspect it had something to do with kmod-Nivida/akmod-Nvidia package and I haven't installed that again but that was installed on the system before the re-install.

@alfC Yea it's annoying. I have multiple systems with Fedora and I have this problem with one of them. Hasn't happened since the re-install. I seen someone suspecting the NVIDIA module from rpmfusion and this system had that, I haven't installed it on the re-install.

fyi...I've had 3 installs get unstable after using rpmfusion kmod-Nivida/akmod-Nvidia package in attempt to get steam operating. The last crash came soon after the package install, before I installed steam.
