Subject [jira] [Commented] (GUACAMOLE-125) Sometimes session is not initialised on Full screen
Date Fri, 18 Aug 2017 16:52:00 GMT


Duane Webber commented on GUACAMOLE-125:

Nick, Michael,

    Thank you again for your efforts in identifying a resolution for this issue.  Regarding
the docker file, I'm able to - I have not done it yet - create a docker file which uses freerdp-1.1;
however, that will overlook other Guacamole docker users and will be redundant if others are
doing the same.  Upon CentOS' update to freerdp-1.1+ the official docker image can be modified
to remove the additional build steps.  Given that many docker consumers are required to maintain
and support numerous docker and docker-compose files, maintaining one less docker file benefits

Please let me know if you can update the official docker file to include the fix?  Without
the fix, anyone using remoteapp that requires a screen size of greater than 1024x768 is basically
useless (as is the case with many desktop applications).  Remoteapp is one of the more powerful
features of RDP, in my opinion, because it simplifies users' workflow and server management.

Thanks, Duane

>                 URL:
>             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: Critical
>         Attachments: fj1.png, fj2.png, fj3.png, fj4.png, fj5.png, fj6.png, notepad_size_limit_detail.jpg,
> 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
