When I start my laptop, it shows a black screen with these messages and nothing happens afterwards.

  • what did you change on your system? why is it not starting anymore? –  Apr 11 '18 at 09:55
  • I changed nothing, I switched on my laptop after 25 days and saw this error window. 25 days before, it was working fine. – farazch Apr 11 '18 at 10:10

Once the system is hang, try pressing few common combinations such as:

  • Control-C
  • Control-Z

If this won't help, run the system in a single mode and investigate your logs and startup scripts.

The Apache2 warning isn't the main cause of the issue, so you should check further more.

You may want to boot your Ubuntu with more verbose output and see if anything can come up.

Check also available Actions using magic SysRq key which can help you to dump kernel debug info or kill the hang processes.

Consider also disabling startup services, see: Which startup applications can I safely disable?
