Ubuntu – Do some applications in Unity start “maximized” but not integrated into the panel

maximizedpanelunity

When I start some applications like Gimp or update-manager they start like if they where maximized but they have window decorations, are not integrated into the Unity panel and therefore move towards the screen bottom.
I also tried to force maximize behaviour via compizconfig-settings-manager but that doesn't change anything.

What can I do to start these applications maximized with integration into the Unity panel?

Or search for gDevilspie in Software Center and install from there.

How to use?

  • Once installed, Hit Super key (Windows key) to open Unity dash and search for "gDevilspie" and open it.
  • Open "Gimp".

  • In gDevilspie click on "add" to add a new rule.

  • In "Rule Editor" Click on "Get", Select Gimp window and "Apply".

Now whenever you will start "Gimp" it will automatically be maximized. You can add rules for "Update Manager" or any other program in the same way.
