Doc Type: Bug Fix
Doc Text:
In autoconf mode, remote-viewer opened as many windows as configured guest's displays. If the guest has more configured displays than the number of client's monitors, extra windows will be opened. Now, the extra guest displays are hidden. In autoconf mode, the number of fullscreen windows matches the number of monitors.

Description Tomas Jamrisko 2013-07-18 09:10:49 EDT
Description of problem:
Virt-viewer sometimes opens one too many windows when fullscreen is configured when connecting to a windows guest

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

How reproducible:
100 %

Steps to Reproduce:
1. Connect to a windows guest without fullscreen autoconf
2. Open several additional monitors (more than physical on client)
3. close the session.
4. Connect to the guest again, this time with autoconf enabled

Actual results:
First n monitors will be correctly open on first n physical monitors, but at least one addition guest monitor will be open partially overlapping one of the others

Expected results:
Guest should have at most the same number of monitors as client.
Comment 1 Marc-Andre Lureau 2013-07-18 12:21:20 EDT
grr, hard bug to fix it seems.

there is no relation between client monitor config request, and current received configuration (in fact 1 request, can trigger n server monitor config reply that may be related or not), so we will have to hack something that might have undesirable side effects. So what we could do is make sure to disable monitors that don't fit in fullscreen, I have been trying to do that...

The bug doesn't seem to easy to reproduce with the linux build, I think it shows that this is somehow also racy.

weird, I can't reproduce on XP either, but with win7 100%..

are you sure you tried with auto-conf? if not autoconf, it's expected we open as many windows as guest monitors.
