[Qemu-devel] [Bug 483251] Re: ctl+alt+F does not leave full screen

[6Kirk Bates]

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.

  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.
