[Peter Sakellarakis]

Ubuntu Mate freezes after some hours of continuous playing youtube videos and needs reboot. Some times it freezes black after the screen saver is on.

Hello,
Several questions here:
1. Can you try to produce this with generic Ubuntu?
2. Does you system stop responding when this happens (CapsLock LED not working, magic key not working and etc)
3. Can you provide the syslog after this to see if it contains any useful information.
Thanks
