Comment 0 for bug 923569

I have a dual monitor setup with twinview. After Unity crashes and does not restart, I have to switch to a terminal and re-run Unity manually in order to interract with windows. Before I do this, windows maximize to only one monitor and I have a panel on both screens. (The top of my screens are not vertically aligned.) After restarting Unity, it treats the whole display as one big monitor. Windows maximize across both screens and there is only a panel on the first monitor (because it has disappeared off the top of the other one.)

To reproduce:

1. Do something that crashes Unity, such as https://bugs.launchpad.net/ubuntu/+source/nux/+bug/923567
2. Repeat step 1 until Unity no longer automatically reloads. (might not be necessary)
3. Switch to a console with ctrl-alt-f1 and log in.
4. DISPLAY=:0 unity
5. alt-f7 and maximize any window.
