Fixed In Version: virt-viewer-0.5.6-1.el6 Doc Type: Bug Fix
Doc Text:
Previously, starting a virtual machine in full screen mode would prevent the guest resolution from being changed; it would always revert to the native monitor resolution. Now, spice-gtk correctly sets the full screen state on start-up in order to disable the guest auto-resize function appropriately.

Description Vimal Patel 2012-08-06 22:06:12 UTC 
Description of problem:
When using remote-viewer to connect to a guest in full-screen, the VM appears with the resolution of the client.  If the resolution is attempted to be changed (Display Preferences) it cannot be done, The screen flashes with the resolution that you try to change it to, but then reverts to the original resolution.

How reproducible:

Steps to Reproduce:
1.  Connect to a guest in full-screen (remote-viewer spice://<host>?port-<port> --full-screen &
2.
3.
  
Actual results:
Flashing of modified resolution, but it won't be kept, so it reverts back to the original resolution, and it cannot be changed by the user.

Expected results:
User can change resolution, should be kicked out of full screen if the Display can't handle it.

Hi Vimal,
I can not reproduce this issue with:
virt-viewer-0.5.2-9.el6.x86_64
libvirt-0.9.10-21.el6_3.3.x86_64
qemu-kvm-0.12.1.2-2.295.el6_3.1.x86_64
spice-server-0.10.1-10.el6.x86_64
spice-gtk-0.11-11.el6.x86_6

#remote-viewer spice://10.66.*.*:5901 --full-screen
I used win7 as guest,running on RHEL.
I changed the resolution between 1024*768 and 800*600,it works well.
Did you connect to a RHEV guest? What's the graphics XML? And any other configuration?
Comment 3 Vimal Patel 2012-08-17 11:46:21 UTC 
Hi Yuging,

I created the guest from Virt Manager (client and host on the same machine), and I am connecting from a RHEL 6.3 client to a RHEL 6.3 guest, but I just tried it also on a Windows 7 guest, and I see the same issue it shows the changed resolution for a couple seconds flashes, and then goes back to the original full screen resolution.

Where do I find the graphics XML info?

Here's what I see from Xorg.0.log:

Hi Vimal,
I still can not reproduce this issue with win 7 installed by virt-manager.

> Where do I find the graphics XML info?

#virsh dumpxml <guest>
Comment 5 Vimal Patel 2012-08-21 14:27:17 UTC 
Hi Yuping,

Thanks for the assistance.
I will attach the xml file for the RHEL63 image I was seeing the issue with.  The virsh commands worked after restarting libvirtd.

Reproduce steps:
1.Install a guest with spice + qxl,please select qxl and spice in installation steps.

2.#virt-viewer -f rhel63-1 --debug --debug-spice
3.The guest will auto adjust the resolution to 1920*1080.
4.Change the resolution to 1024*768-> fail,it returns to 1920*1080.

Attach the log.

Comment 15 tingting zheng 2013-07-04 08:19:36 UTC 
I can reproduce this issue with:
virt-viewer-0.5.2-9.el6.x86_64
libvirt-0.9.10-21.el6_3.3.x86_64
spice-server-0.10.1-10.el6.x86_64
spice-gtk-0.11-11.el6.x86_6

Tested with:
virt-viewer-0.5.6-1.el6.x86_64
libvirt-0.10.2-18.el6_4.9.x86_64
spice-server-0.12.3-1.el6.x86_64
spice-gtk-0.20-1.el6.x86_64

Connect a guest with full screen,the resolution can be changed,so move the bug to VERIFIDE.
