Can guacamole change the viewport to a single monitor on a multimonitor system? Is this a feature VNC clients possess in general? I have VNC server running on a multimonitor system, ie a laptop with its built-in 1366x768 screen and a 1920x1080 monitor. When I check the VNC server logs it indicates it shows that a 3286x1080 virtual screen has been created. Regardless of how I set the geometry to be 3286x1080+1366+0, or leave it to the defaults this is what guacamole displays. Screen shot from guacamole interfaces of 3286x1080 screen I have tried x11vnc -geometry 3286x1080+1366+0 -noxdamage -ncache_cr -wait 5 -defer 5 -display :5 and x11vnc -noxdamage -ncache_cr -wait 5 -defer 5 -display :5 I didn't fare much better with x0tigervncserver either.

See 29/08/2024 13:40:11 WARNING: the warning message printed above for more info. 29/08/2024 13:40:11 Can guacamole be made to pan the necessary part of the virtual screens and apply the scaling to that portion only? When I use krdc I'm able to scroll the windows to the necessary part of the screen and the screen is normalized. When I use a laptop screen with 1920x1080 screen which matches the monitor, using the option -geometry 3840x1080+1920+0 the display works fine as expected.
