Re: Prevent VNC display from stretching?
Thanks for the help, Jeff! I modified three lines, the two scale ratios (I changed to 0.01) and the "autoFit : true," line I changed to "autoFit : false,". The scale ratio now adjusts by 1% at a time, as expected. However, it looks like the window is still "autoFitting". Previously, I had set the geometry of the VNC server to be close to my browser window. When I launch the VNC session, it's at 101%. I can zoom in past 101% but I can't zoom out below that, not without unmaximizing the window. When I make the browser window smaller, I can zoom out to until it fits the window. It seems Guacamole doesn't want to shrink the VNC display to less than the browser window and add a black border around the top & bottom (like it does for the left & right). Are there other values in that guacamole.js file that I should be looking at? I'm no web developer so I had to do a bunch of google searching just to figure out how to extract the .war file and re-minify the js file. -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/
Re: Prevent VNC display from stretching?
Hi Andrew, If you are using the stock Gaucamole client, you can modify the default behavior in the javascript to prevent autoFit at startup and set the zoom increments to whatever you want. In guacamole.js you will find the below. Don't foget to re-minify the javascript into guacamole.min.js after you make changes. Regards, Jeff /** * Whether the Guacamole display should be scaled to fit the browser * window. * * @type Boolean */ autoFit : true, $scope.zoomIn = function zoomIn() { $scope.menu.autoFit = false; $scope.client.clientProperties.autoFit = false; $scope.client.clientProperties.scale += 0.1; }; $scope.zoomOut = function zoomOut() { $scope.client.clientProperties.autoFit = false; $scope.client.clientProperties.scale -= 0.1; }; On 2/22/18, 7:24 AM, "amlamarra" wrote: I'd like to disable scaling in VNC.

And those zoom buttons don't work very well either. It only goes in increments of 10%. And if you're at 109% and zoom out, then you're set to 99%... It just seems kinda wonky. I wasn't sure if there was anything I can do to set scaling to 100% no matter what. -- Sent from: http://apache-guacamole-general-user-mailing-list.2363388.n4.nabble.com/ smime.p7s Description: S/MIME cryptographic signature

So, supporting each of these implementations would be difficult, and some of them would not be possible, for commercial products that do not provide source code or documentation for their extensions. -Nick

I'm not certain how feasible the first option is in Guacamole; the second - getting VNC to dynamically pass resolution from client to server - is not possible, and is a limitation of the VNC protocol, not of Guacamole. You can work around it using xrandr to add the client resolution and resize the VNC server display, but I don't know of a way to automate that process native to VNC. -Nick
