I have recently set runlevel 3 as a kernel parameter instead of runlevel 5, though this has caused a little bit of a problem... Because when I execute startx and then once the GUI has loaded, if I close the lid, wait for the right amout of time, or do the keyboard shortcut to suspend, it does, but when it wakes up again it does not ask for a password as it should and did on runlevel 5, so this is a bit of a security risk.
How can I get it to ask for a password when waking up from suspend when running on runlevel 3 in X?

I am running Ubuntu GNOME 15.10 with GNOME 3.18.

This is another of my security worries related to this (I am just linking the question as it is similar): Can console be suspended and ask for a password on wakeup?

Changing runlevels is an excellent method to do a Root Cause Analysis, but hardly a solution!

At best, it's a workaround and as you noticed, it creates a sleuth of other problems, so if you need to disable X, just do so and:

Please!

Please!

Please!

Set your runlevel back to 5!

Alternatively,

sudo nano /etc/default/grub

and:

  1. Change GRUB_CMDLINE_LINUX=”" to GRUB_CMDLINE_LINUX=”text” which will force Ubuntu to boot directly into Text Mode.
  2. Uncomment #GRUB_TERMINAL=console by removing the #which will force the grub menu into B&W Text Mode

(credit for the alternative method goes to @Serg!
