[Bug 1281053] [NEW] Unity application panel does not appear with mirrored screens on Intel graphics

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:


My setup
========

I'm using Ubuntu 13.10 on a HP TM2 with hybrid graphics (vga-
switcheroo):

- integrated card: 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 02) (prog-if 00 [VGA controller]) 
- discrete card: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [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.
