Hoping someone is able to either suggest some useful troubleshooting – or a solution 😀 – to a strange problem we’re having.
We use NoMachine to connect to a number of Linux desktops, ranging from Fedora 24 up to Fedora 29. Most work OK, but there are a couple which for some reason NoMachine doesn’t detect the second display. Bizarrely, if you connect from the machine when close by, you can see that on the NoMachine client, when it looks like the mouse has hit the edge of the screen on the physical screen the cursor is still actualy moving onto the second screen and across it, despite it not showing on the NoMachine client.
Investigating further, it appears that NoMachine on the host is unaware of the dual-screen configuration, hence it’s not being presented to the client.
Any ideas or thoughts very much appreciated.
Thanks in advance!
