Newbie trying to use Ubuntu on Dell Computer with VGA display and TV as second monitor.

In GUI I set an option that turned off both my screens. Now, when the system boots, the screens go blank. I can boot by typing Ctrl+Alt+F1 and get the system prompt.

  • How can I reset to get the default setting/display back?

It is easy,

You can use shortcut key Start+P OR Command+P Key To Toggle Multi-Screen Modes Like Windows.


Log into any tty and run sudo startx

  • Start/Command is Start/Command Button of Windows TO launch Start/Command menu in Windows/Mac/Linux. Apr 5, 2014 at 18:57
  • I rebooted, and hit Winows key + P, nothing happened
