Sometimes my system gets freezed
You needs to figure out what's triggered the freeze,
tail /var/log/dmesg or
journalctl -f get ERR logs
how to fix this?
You can try restart Xserver, instead of power cycle your machine.
Using keyboard combination
or using GUI implements
killall X (you ought to start Xserver at tty on your own)
