Hi forsubhi.

It looks like 'Power Management' (pm) is set to send to sleep your machine after a determined period of time.

If you want to avoid that, check your settings (take a look here (https://wiki.ubuntu.com/KubuntuPowersave)), and if that doesn't work, check your BIOS in case there are other hardware settings configured.

Hope that helps,
Regards.
