Please describe the problem:
After applying the settings (e.g. changing the screen resolution), if the number of connected outputs didn't change, then fill_out_screen_info() is called with needs_reprobe=FALSE. This is correct but info->min_width, info->min_height, info->max_width and info->max_height are not filled. As a result, they are all set to 0, which causes the Display capplet to believe that the allocated front buffer is not enough (being 0 x 0 ) and prevents the applet from applying a new screen resolution unless the applet is restarted.

Steps to reproduce:
1. Launch the Display capplet
2. Change the screen resolution to a different resolution and apply your settings
3. Repeat step 2 with a different resolution


Actual results:
An error dialog warns the user that the settings cannot be applied.

Expected results:
If the front buffer is enough, the settings should be applied.

Does this happen every time?
yes

Other information:
Solution: Gnome desktop should re-use the previous screen size when needs_reprobe=FALSE in screen_info_new()
