I want to change Key short cut to Super+L for LockScreen but it is not working. If I try any other combination like CTRL+ALT+L or CTRL+ALT+G , it works.
Win+L combination used to work in 11.10.

Yes, it's very annoying, and hard to remember the exact fix. So hopefully this will help you, and also be an easy way for me to look this up next time I do a fresh Ubuntu install.
There is duplication & conflict between the Gnome Keyboard Shortcut settings (as depicted in your screen shot) and the same settings in the new Unity desktop. Ubuntu (well, Gnome) provides a UI for editing the Gnome Keyboard Shortcut settings but as you've learned, they don't work if they conflict with Unity. And there is no UI installed by default for managing Unity.
Note that to get 'Super-X' style shortcuts to work, you will have to change the 'key to show the launcher' setting, which means that the Super/Windows key will no longer open the launcher. If that's OK with you, continue...
Here is what I do:
Install compizconfig-settings-manager (some will warn you not to, because it gives you enough power to really mess things up). There may be a way to change these without using CCSM but if so, I don't know it. Install it via the Ubuntu Software Center, or:
$ sudo apt-get install compizconfig-settings-managerRun CompizConfig Settings Manager; acknowledge the warning message.
- Locate and click the
Ubuntu Unity Pluginicon in theDesktopsection - Change the
Key to show the launcher(on theBehaviourtab). To do this:- Click the button which says
<Super> - Click
Grab key combination - Press a new key or key combination (this will, from now on, open the Unity launcher); I use
<Alt>-<Super>
- Click the button which says
The <Super>-L 'Lock Screen' combination that you already set up should now just work!
Bonus
Note that CCSM also provides its own facility for setting keyboard shortcuts. For things not included in the gnome-control-center, you may have more luck defining custom shortcuts in CCSM. If you select Commands from the General section in CCSM, you can define custom commands, like I've done here:
...and then, you can associate those commands with specific key combinations, like this:
As you can see, I've configured Super-E to launch the Gnome text editor, and Super-C to launch the calculator. I find both of these very handy.

NB: The screenshots are a little different for 13.10 but this method still works. Note that
/usr/bin/gcalctooldoesn't exist in 13.10; it's/usr/bin/gnome-calculator– Lambart Mar 12 '14 at 19:24 -
Looks like 14.04 has Super-L preconfigured to lock the screen, among other more convenient shortcuts. However, I still had to install CCSM and reconfigure what's now called the "Key to show the Dash, Launcher and Help Overlay", in order to configure Super-T for anything besides the hard-coded but rather useless (to me) Trash browser. – Lambart Jun 23 '14 at 21:57

Looks like unity-tweak tool will do the trick; no need to install ccsm.
sudo apt-get install unity-tweak-tooland then run it. Under Unity->Additional, and change the 'Show the Launcher' setting. – Lambart Jun 24 '14 at 18:42

This is a confirmed bug #951805 in Ubuntu since 12.04 beta 1 stage. Unfortunately no solution is available as of yet, but everyone being affected by this bug can sign in to Launchpad and subscribe to the bug report for future updates.

If you are using ubuntu and none of the solutions worked for you, then you may consider resetting to default settings.
You wont lose anything except reverting your settings to defaults,
$ dconf reset -f /
Note that this may also reset application that use dconf to save settings.

Win/Super + lmake their display settings reverted to a previous setting? I used the System Settings to rotate my display and I noticed that pressing Win+L will flip flop it between normal rotation and the 90degree rotation. – user29020 Dec 19 '14 at 22:01
