I found out that if this problem only happens if, prior to setting screens in mirrored mode, the panel is moved on the external screen, i.e
1. Connect external screen 2. In the display configuration tool enable screen and move unity panel to external screen 3. Select mirrored screen 4. Bug: application panel does not appear when icon is clicked but 1. Connect external screen 2. In the display configuration tool ensure that the panel is on the laptop screen 3. Select mirrored screen 4. Ok, application panel appears -- You received this bug notification because you are a member of DX Packages, which is subscribed to unity in Ubuntu.

[AMD/ATI] Park [Mobility Radeon HD 5430/5450/5470] (prog-if 00 [VGA controller]) Problem ======= I need to work using a mirrored screen setup, with an external screen connected to VGA (resolution: 1024x768). When using the integrated intel card the application/search panel does not appear when I click on the launcher icon or press the keyboard shortcut: there is just a slight shadow on the top left corner (see attached screenshot). However, if I switch to the discrete card (AMD/ATI) I have no problems at all (panel shows up in mirrored mode). In non-mirrored mode the panel shows up using both cards and works correctly on both screens.
