Description Andrei Stepanov 2015-10-26 07:28:15 EDT
The bug is about multi screen setup with real monitors.

virt-viewer has a menu to go to fullscreen mode / leave fullscreen mode

There is different behavior for "Leave fullscreen" button.

1. If user connects in fullscreen, "Leave fullscreen" occurs in all displays.

2. Other ways to activate/deactivate fullscreen mode works independently for each display.

There should be consistency.

As far as I understand this is the expected behavior.
Please, take a look on these patches were the behavior/requirements for virt-viewer in fullscreen multimonitor mode is/are described.


This patch should be part of virt-viewer, let's try to revisit it soon.
Comment 3 Fabiano Fidêncio 2015-10-26 16:59:29 EDT
To be a bit more specific. It's related to item D5 of the link I posted in the comment 2.

And here is a chat I had with Jonathon about this:
18:24 <  fidencio> jjongsma: about multimonitor fullscreen behaviour. when you open remote-viewer on fullscreen mode (-f) and then you 
                   leave fullscreen mode, we do it for all windows. shouldn't we do that only for the window where the user clicked to 
                   leave fullscreen?
18:38 <~ jjongsma> fidencio, this is a long-standing question. We've treated this differently since I've been on the project, but I'm 
                   not sure whether we really should.
18:46 <  fidencio> I personally tend to say that the current behaviour makes sense, as long as it's documented somewhere
18:46 <~ jjongsma> fidencio, I think the historical explanation is that fullscreen mode used to be an app-level option
18:46 <~ jjongsma> e.g. you could only have all windows fullscreen or all non-fullscreen
18:46 <~ jjongsma> then elmarco introduced per-window fullscreen at some point
18:47 <~ jjongsma> and startup fullscreen remained with the old behavior

Getting back to the link posted in the comment 2, it says: "that will need to be changed.", so, let's change it.
Comment 5 Fabiano Fidêncio 2015-10-27 09:05:40 EDT
Here is a proposed patch:

OTOH, it is a quite big change that would affect pretty much all costumers using fullscreen.
So, is it a valid request? I would like to hear something from PM wrt this bug.
