I just installed Ubuntu on a dual boot. When I run the system with Ubuntu, it goes for about 30 seconds and then the screen turns black and showing the message Enter power save mode. I have to restart the system over and over again.

  • My computer system is a Dell XPS 8100.

When I run the system under windows, I do not have this problem. Is there anyone who can help me with this terrible issue and tell me step by step what to do?
