once virtual machine is up and running hitting the maximize button on the title bar of qemu maximizes the window.
hitting ctl+alt+F makes window pixel per pixel but not full screen (smaller) and leaves the last scaled image in the background.
hitting the maximize button on the title bar again sends it to full screen.
hitting ctl+alt+F does not return to windowed mode.

This appears to be fixed in qemu-kvm 0.12.3 for me.

I'm able to ctrl-alt-F over and over, ad nauseum, in and out of full screen mode.

Marking the Ubuntu task fix-released. Please re-open that task if you can reproduce this on Lucid.

I'm leaving the upstream task as 'confirmed' because Ingo Molnar reported this problem on the qemu mailing list just a few days ago. Someone should check this against upstream qemu and update that status accordingly.

I had to "dpkg -i" some lucid packages, after manually removing some karmic stuff. After some trial-and-error this seems to work. It would have been handier though if the Karmic packages were updated automatically. I do not know whether this is possible.

We use SDL fullscreen mode which currently implements the behavior you're describing.

For me - the issue turned out to be related to an NVIDIA BIOS setting. I travel a fair bit so care about battery life and as might be expected when travelling only have the laptop screen as the monitor: so I selected Integrated Graphics. This causes the bad behaviour, in as much that, when I change the BIOS setting to Discrete Graphics - which is faster and I suspect my more desk bound colleagues would choose out of choice - it works just fine.
