Nxserver can connect to a display but not start one

[jagalactic]

I use NoMachine at work on a corporate license, and I would like to use it at home on a Fedora 36 system. I can start a display from the F36 console (“startx”), and that works. NoMachine can connect to that display, but if no display is running it can’t start one – I get the “cannot find the default environment…” popup.

I’ve tried the following in /usr/NX/etc/node.cfg:

#DefaultDesktopCommand "/etc/X11/Xsession default"

DefaultDesktopCommand "/etc/X11/Xsession gnome-session --session=gnome'"

#DefaultDesktopCommand "/usr/bin/gnome-session"

#DefaultDesktopCommand "/usr/bin/startx" 

(the uncommented line is what works for me at work, but not at home)

What I want is a gnome session that can be resized to fit full-screen on my monitor (which is QHD – 3440×1440) – which does not work if I’m connected to a display that is bound to an actual monitor on the Linux box.

[jmg@fedora ~]$ sudo /etc/NX/nxserver --version

NoMachine – Version 8.3.1

Client is also 8.3.1, on a Mac running Ventura.

Any tips would be appreciated!

Hi, the image didn’t upload correctly for some reason. Can you send it to forum[at]nomachine[dot]com?

Hi.

Are those commands are from Fedora 36? Just try this if you have gnome:

DefaultDesktopCommand "/etc/gdm/Xsession gnome-session"

Yes, it’s fedora 36. With this command I don’t get the same error, but the NoMachine server dies pretty quickly, and I never see a desktop.

Thanks….

Aren’t you using gdm? Check where is placed Xsession script.

sudo find /etc -name "Xsession"

and use those path in DefaultDesktopCommand. For example:

DefaultDesktopCommand "/etc/X11/xinit/Xsession gnome-session --session=gnome"
