One thing I like for MacBooks is that they are usable within a second after opening their lid when they were on stand by.

Ubuntu always requires me to enter my password when I resume from suspend, which can be very annoying.
How can I disable this?

It turns out that this really is undesired behavior, and there are several bugs related to this issue.

Start gconf-editor (press ALT-F2, then type gconf-editor).

Seach down to Apps/gnome-power-manager, then click on "lock".

You have two choices : either untick "suspend", or tick "use_screensaver_settings" (of course, you'd then have to go to screensaver preferences and remove the "lock screen" option.

Thank you, this would be be the perfect answer! If only it would work :(. I have tried both options and neither of them works. Proof: imgur.com/w4KVj&Sl385l I would report a bug but I'm not registered on the Gnome bug tracker. –  Ingo Jan 22 '11 at 12:24
    
Note that "suspend" and "hibernate" options are ignored if "screensaver" is ticked. Try playing with the values and see what happens. Certainly worked for me, so perhaps a hardware issue? –  Scaine Jan 22 '11 at 13:08
    
Doesn't work for me either :\ (tested it on three different machines) –  Stefano Palazzo Jan 22 '11 at 13:40
    
This works for me (so far) on : Dell Vostro V13, Toshiba U400, Dell Inspiron, couple of home-built PCs, Acer Revo Ion and a few friends laptops I've built - mostly Toshiba's and Dell's who's models I forget. I can't understand why this isn't working for people. –  Scaine Jan 22 '11 at 13:56

Yes it is really weired. This bug on launchpad might relate to it bugs.launchpad.net/gnome-power/+bug/553646. I am marking the question as answered as it is indeed the correct procedure, although it might not work on some machines. –  Ingo Feb 6 '11 at 14:22

As mentioned in the comments, the solution mentioned above doens't work for Ubuntu 11.10. Please see How do I stop the screen from being locked on suspend? to 'fix' the issue on 11.10.

There is more work to do, beyond unticking “use screensaver settings”.

This will disable the locking, altogether, so you won't be able to lock the screen even if you wish to, but if you don't care, just enter this command:

gsettings set org.gnome.desktop.lockdown disable-lock-screen 'true'
