If port is specified, the viewer listens on that port instead of default port. Can be useful in case of conflict with other installed software hotkeys. Required for using the color options below or saving a custom configuration otherwise the settings from quick options always override.
Fewer colors can significantly reduce the required bandwidth. Note: Grey colors only work with 32 bits color screen resolution. At work I have a 20" monitor that runs at x, while at home I use my laptop with its resolution of x If I set the vncserver to run at x I miss out on a lot of space on my monitor, whereas if I set it to run at x it doesn't fit on the laptop's screen, and I have to scroll it all the time.
Real VNC server 4. Start the server with:. Found out that the vnc4server 4. Unfortunately the feature was hard to find because it is undocumented. So here it is From a terminal in a vncviewer with: 'allow dymanic desktop resizing' enabled use xrandr to view the available modes:. I just start vncserver without any -randr or multiple -geometry options. I think your best best is to run the VNC server with a different geometry on a different port.
I would try based on the man page. I think the developers who wrote the code are much smarter and the hard coded list is just a sample of values. It leads to the conclusion that there must be a way to add custom modelines and man xrandr confirms it. With that background if the goal is to share a VNC session between two computers with the above resolutions and assuming that the VNC server is the computer with the resolution of "x":. Interestingly no one answered this. In TigerVNC, when you are logged into the session.
Click on the resolution drop down, there are various settings available including p. Select the one that you like. It will change on the fly. Make sure you Apply the new setting when a dialog is prompted. Otherwise it will revert back to the previous setting just like in Windows. Use it like this: vncsize With this the resolution changes to fit the size of the client window no matter what it is, and it's not zooming , it's actual resolution change I can see the new resolution in xrandr output.
I tried all I could to add a new resolution to the xrandr, but to no avail, always end up with 'xrandr: Failed to get size of gamma for output default' error. I'm not sure about linux, but under windows, tightvnc will detect and adapt to resolution changes on the server.
So you should be able to VNC into the workstation, do the equivalent of right-click on desktop, properties, set resolution to whatever, and have your client vnc window resize itself accordingly. On the other hand, if there's a way to move an existing window from one X-server to another, that might solve the problem. I think you can use xmove to move windows between two separate x-servers.
So if it works, this should at least give you a way to do what you want albeit not as easily as changing the resolution. As far as I know there's no way to change the client's resolution just using VNC, as it is just a "monitor mirroring" application. That should work if you don't use too small font sizes. I'm a windows user, so this might be a wrong guess, but: Isn't there something called X-Server running on linux machines - at least on ones that might be interesting targets for VNC - that you can connect to with "X-Clients"?
VNC just takes everything that's on the screen and "tunnels it through your network". If I'm not totally wrong then the "X" protocol should give you the chance to use your client's desktop resolution. Give X-Server on Wikipedia a try, that might give you a rough overview.

Thanks Nathan, even the realvnc folks dont seem emphasize the xrandr feature See also my bash function below to allow cycling through the randr resolutions.

Nathan I tried to use the solution you gave but without success.
I wonder if this works with tightvncserver? DimitryK I had tightvncserver and doesn't work it. I purged it and installed real VNC. I recommend it. All landscape resolutions: x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x,x Show 3 more comments.
