I know it’s a common issue but I’ve not been able to resolve it using many solutions I found, so I need your help if possible !
I’m connecting from a Windows 10 physical machine to a Linux VM (Ubuntu 20.04).
I installed Gnome desktop (gnome-session) on the VM and have been able to connect using NoMachine, easy.
Thing is that the default resolution is “1152×864”, and there are no other available resolutions.
So I tried the “xrandr” solution to add a custom resolution. I’ve been able to select “1920×1080 (16:9)” resolution after that, but thing is that it still doesn’t fit the screen (see screenshot).
By the way, when I added the custom resolution with xrandr, it showed me an error/warning : “xrandr: Failed to get the size of gamma for output default”. But the resolution was still added to the list.
I tried every “combination” of display settings on the (client side) NoMachine soft.
Does anyone have a hint about my issue ?
– Windows 10 (client)
– Ubuntu 20.04 (host)
– NoMachine v6.12

What i have noticed is that you are having the Ubuntu virtual machine:
– I would recommend to install hypervisor drivers and verify if your machine is able to use different resolutions.
Or You may try to switch off your X server and let NoMachine create display for you. You can stop or disable you Display Manager, and create a connection to that desktop.

Both Windows and Linux machines are different physical machines.
They both are on the same LAN. The only physical machine I have in hand is the Windows (client) machine. I don’t have access to the physical Linux machine and I can only “login as root” or restart/stop the machine.October 9, 2020 at 20:45 #29861fishermanModerator
I understood it is virtual machine as you have mentioned “Linux VM (Ubuntu 20.04)”.
If you Linux machine is without monitor attached probably Linux X server if forcing one resolution. Possibly you can attach hdmi dummy dongle or you can let NoMachine create a display on the fly rather than using physical one.
Try to turn off lightdm or gdm:
sudo service lightdm stop
and then restart NoMachine server:
sudo /usr/NX/bin/nxserver –restart
