Subject [jira] [Commented] (GUACAMOLE-125) Sometimes session is not initialised on Full screen
Date Sun, 21 May 2017 22:07:05 GMT


Fermi Jiang commented on GUACAMOLE-125:

In the above test, chrome is running in Windows 8.1 Pro with dual monitors 1600x900 and 1920x1080
(the latter one is used for the test).

The xfreerdp is running in CentOS 7 in Visual Box VM with screen resolution 1920x975.

The RDP server is running Window Server 2016 in Hyper-V VM with screen resolution 1600x900.

The windows applicaiton is just a sample MFC project, though I think it is irrelevant. The
guacamole I tested was customized by other developers. But most of the modification were related
to authentication, access, labels on menu, etc.

I cannot understand why there are two same remote applications displaying in xfreerdp. The
session appeared to be taken over, because I can see one client in the other out. Initially
in guacamole, I can only see one remote application, no matter how I move or resize the window.
I can see only one process in the task manager as well. But after guacamole out and xfreerdp
in, I can see two same windows stacked together (putting the top one aside). I can see two
processes listed in the task manager. After xfreerdp out and guacamole back again, the two
windows remained there.

>             Project: Guacamole
>          Issue Type: Bug
>    Affects Versions: 0.9.9, 0.9.10-incubating
>         Environment: Guacamole running on Debian 8.6
> Forwarding a windows 2012 R2 session
>            Reporter: Frank Giroud
>            Priority: Minor

> Sometimes after logging in (which happens to be Full scren) the windows session or the
RemoteApp is not launched in full screen.
> In fact it behaves like there were a pseudo-resolution smaller than the required one.
> The browser (Chrome is open in a 1920*1200) but the screen displayed is locked to something
like 1024*768 or so. 
> When you click on the Fullscreen button. It open and let a black screen all around in
the web browser. .
> -The behavior is the same if you start a windows session , the windows desktop displayed
in the web browser is in a 'smaller display' and what remains is black.- Haven't succeed to
reproduce after all
> I have succeeded to find a way to reproduce the behavior "kind of" more often.
> In my example i configure notepad++ to be a remoteapp (launch by ||notepad in guacamole
> # Launch a session through Guacamole => No probleme guacamole can be set in fullscreen
(on all the browser window)
> # Unmaximized the application
> # Ctrl-Shift-Alt menu => Disconnect
> # On the guacamole option menu (3 choices) => Reconnect
> # The result => my screenshot
