Description Satish Balay 2013-12-02 12:12:05 EST
Description of problem:

I'm unable to get out of fullscreen mode from the VM

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. start virt-manager
2. select win7 VM to start
3. toggle the VM to full screen
4. Now attempt to toggle back to normal mode.

Actual results:

There is no menu for toggling back visible

Expected results:

Expect to see a full-screen menu option dropdown - when the mouse is at the top/middle of the screen.

Additional info:

This worked fine on F19

Yeah there's definitely some funkyness here, but only with VNC for me. I assume your VM is using VNC but if not please correct me.

Affects virt-viewer and vinagre so likely a gtk-vnc, though I tried running against older gtk-vnc-0.5.2 and still hit the problem. So maybe a gtk update is tickling a gtk-vnc bug, I'm trying to narrow it down now.
Comment 2 Satish Balay 2013-12-05 17:21:29 EST
Yes - I have VNC in my display settings for the VM.
Comment 3 Cole Robinson 2013-12-06 16:10:40 EST
Some more investigating:

reproduces on gnome shell and kde
I can't get it to reproduce in a VM though
reproduces on two physical machines with f20 alpha and f20 beta livecd, though that's after pulling in the virtualization group which will grab latest gtk-vnc in F20, so not entirely alpha/beta packages.

I still suspect its a gtk3 or similar change that's tickling a gtk-vnc issue, but without being able to reproduce it in a VM it will make bisecting a pain in the ass.
Comment 4 Cole Robinson 2013-12-16 09:37:30 EST
Scratch that, I can reproduce in a VM. The toolbar functions correctly while the VM bios output is shown, but once it switches to grub or regular bootup, things break.
Comment 5 Philippe Troin 2014-07-01 03:49:22 EDT
Seeing the same problem here.
Comment 6 Philippe Troin 2014-07-01 04:05:43 EDT
I've recompiled and tested various vinagre versions on F20:
 - 3.8.3 (the F19 version)
 - 3.10.2 (current F20)
 - 3.13.2 (rawhide)

All of them have the bug.
The interesting part is that 3.8.3, when ran on F19, works fine.

This points to something else than vinagre as the culprit.
Maybe gnome-shell or gtk?
Comment 7 Daniel Berrange 2014-10-09 11:11:51 EDT
I've not been able to ever reproduce this bug myself which makes fixing it rather tricky !
Comment 8 Cole Robinson 2014-10-29 12:08:40 EDT
ping danpb, didn't you come up with a patch for this? I don't see it upstream
Comment 9 Daniel Berrange 2014-10-29 12:14:49 EDT
Yes, just pushed the fix upstream now
