Description of problem:
When Qemu is toggled fullscreen xrandr configurations with two or more independent displays are reset to mirrored mode.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Setup a dual-monitor configuration for independent displays using the Display Settings applet.
2. Launch some guest OS with qemu.
3. Press CTRL+ALT+F to initiate fullscreen.
Qemu goes full screen but independent monitor configuration is lost.
So, the host multi-screen configuration is changed by launching qemu and making it fullscreen?
How exactly was qemu launched? Using the command line or libvirt? What is the exact qemu command line?
(Note, we don't really recommend people use qemu directly nor use the SDL display backend ... libvirt and the qemu VNC backend is what we put most effort into getting working properly.)
My guess this is an SDL or xrandr bug

"What is the exact qemu command line?
/usr/bin/qemu-kvm -monitor stdio -boot c -m 384 -hda /home/bchrist/work/virt/winxp.img -net nic,vlan=0 -net user,vlan=0 -smb /home/bchrist -localtime -soundhw es1370 -sdl

Understood. There are several reasons why I do this:
1. I've been using qemu since kqemu was border-line closed-source and I'm familiar with it.
2. Frankly, VNC is slow. I can see the advantages on a server, but for a desktop you really need something much faster and SDL is the only option.
3. The problem with libvirt as that copying the OS from one computer to another is not a single-step process. Using qemu directly I can just copy the qcow2 file from my laptop, desktop, or any other computer I want. Last time I used VirtualMachine this was not true.
Okay, I'm going to move this to SDL
Summary is basically that SDL_SetVideoMode(SDL_FULLSCREEN) appears to screw up xrandr configuration; could just as easily be an X bug, so cc-ing ajax
I tested this and it seems that the results are also graphics driver dependant. Can you please test SDL-1.2.14 from rawhide/F-13.
This message is a reminder that Fedora 11 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 11. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '11'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 11's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 11 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 11 changed to end-of-life (EOL) status on 2010-06-25. Fedora 11 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
