I'm actually using Kubuntu 16.04 with KDE Plasma 5.8.

It runs normally, but, when I play a game or after an 1 hour or less of of PC turn on, the graphical environment dies without any way to reboot it through command line or similar.

When that happends, I must to reboot the machine again shutting down or rebooting manually with the reboot button, I don't konw why happends that, so any idea how to fix it or what I must to install to fix that issue?

  • To prevent corrupting the system with a hard reset, consider installing an ssh server (apt-get install openssh-server) and connecting to the machine via another system. sudo shutdown -r now can be used for a controlled soft-restart. While logged in, one can also attempt to diagnose by checking various logs for specific errors. – BenjaminBrink Jan 26 '17 at 23:15
  • Thanks so much for the help, however, I don't have another way to use other system to do that you explain me, there's another way to do something? – JESUS0414 Jan 27 '17 at 21:41
