display: disable the "Apply" button until a change has been made (7.64 KB, patch)

Description gpothier 2009-10-31 14:01:20 UTC 
The Apply button for the screen resolution config applet should be disabled when the user hasn't changed anything. Or, alternatively, it should not do anything. The issue is that having it enabled leads to the following endless cycle:

1. Open the Screen resolution config applet from System/Preferences
2. Change the settings of some monitor
3. Click apply
4. Screens are configured correctly
5. Click "maintain configuration" in the countdown dialog that pops up
6. The config applet is still displayed, with the Apply button enabled
7. Not sure what I should do, so click apply -> GOTO 5

This actually happened to my girlfriend. She was able to setup her external monitor all right but she said the countdown dialog would pop up over and over, and that was because she clicked apply over and over...

This is on Ubuntu Karmic, updated yesterday.
I originally filed a bug in Ubuntu but was told to file upstream: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/465676

Review of attachment 254508 [details] [review]:

I think the request makes sense and the code looks good.

This is a (minor) UI break though so we need a freeze break exception.
