I have an Ubuntu machine that I'm connecting to using the NOMACHINE NX Client. I would to increase the screen resolution (ideally to 1600 x 1200), but I can't seem to do so using the client settings. Is there some sort of limitation or some configuration file I need to edit on the Ubuntu box to increase it?
I faced the exact same problem when connecting from Mac 10.8 to Ubuntu 10.04 via NX, and I used xrandr to fix it.
Xrandr, or X Resize, Rotate and Reflect Extension (RandR) is an X Window System extension, which allows clients to dynamically change X screens, so as to resize, rotate and reflect the root window of a screen.
Follow these steps:
If you're using the NX Player version 4, you're supposed to be able to do this by changing the resolution in the server's OS settings, but in Ubuntu 12.04 the Displays panel is blank during an NX session.
You could try using xrandr to change the resolution that way, but I haven't figured out how to make that work with NX yet. http://www.ubuntugeek.com/how-change-display-resolution-settings-using-xrandr.html
