Multiple client monitors with PopOS!

[deadrabbit]

Hi fisherman,

thank you for your analysis. Unfortunately, I don’t know how to configure multiple virtual displays on the Proxmox/hypervisor level for use with NoMachine.

As a workaround, I’ve switched to using [removed], which natively supports multi-monitor setups in virtualized environments. However, I would much prefer to use NoMachine, as [removed] doesn’t come close to NoMachine’s performance – especially over slower network connections.

If anyone knows how to configure multiple virtual displays in Proxmox that NoMachine can detect, I’d really appreciate any hints.

Thanks for your help!

Hi,

There is a workaround available within the system that you can use for this scenario.
First, check which DRM card is in use by running:
ls /sys/class/drm

This will typically return something like card0.
If the returned card is card0, you can enable the virtual displays using the following commands:
echo on | sudo tee /sys/class/drm/card0-Virtual-2/status
echo on | sudo tee /sys/class/drm/card0-Virtual-3/status

After enabling the virtual displays, you can configure their positions either via the command line or by using the system’s display/monitor settings application. For example:
xrandr --output Virtual-2 --auto --right-of Virtual-1
