I think is the session with problems affecting my collegue: (attachment)
I will try to collect but I don’t know if I can sent depends on the information he collects. There are data that I cannot share, username, ip address…
However is very strange.
We are remoting to the same Physical Ubuntu 18.04 from a Virtual Windows 2012 remote server that is used as Remote Desktop Gateway.
Basically we connect via rdp to Windows and within Windows we run NoMachine.
I don’t have any problems with my session, while he has problems with his session. We remote to the same physical Ubuntu Workstation from a Windows 2012 that for sure has the same configuration. Basically it is the same VM for everyone.
I don’t know if the user did something who can breaks the configuration, however it worked smoothly at the beginning and now there isn’t way to make it work at least at least for him. It worked also before I modified the WayLand configuration.
Maybe reinstalling NoMachine in the Ubuntu Ws can solve?
It is Standard Ubuntu 18.04 Gnome. Today I have uncommented the line WaylandEnable=False and I have rebooted the system.
It works fine for me, I tried few times and I didn’t have any problems but not for the user that have to work remotely.
He connect to the login screen of Ubuntu but it didn’t appear any login name or a box where to login and if it click on the screen he become black.
It seems to be better but now the user seems to have duplicated Icon over the desktop
For the moment i’ve tried to update Ubuntu ed I’m testing now if it works with some stability or not. If it is not stable I will uncomment WaylandEnable=False and I will reboot the system, previously i restarted only the gdm service:
I run the command you told me below the result:

Thanks! I will give update after few test
First thanks to all
Yes after a reboot it works, sometimes i just need to restart the service and kill all the process but if i disconnect and reconnect most of the time i have the white screen, not always but often.
- PhysicalDesktopMode and VirtualDesktopMode are both commented in the server.cfg
- I have also tried to uncomment the wayland=false on the /etc/gdm3/custom.conf and the I have restarted gdm3 services, the result it is not a white page but it not working fine. Maybe I need restart?
In One of the session log, the one owned by gdm I found this error:

Thanks for you reply I started to look under that folder but now i need to understand what to look for
There are some folder where i’m the owner but some others as gdm as owner. Basically i have 5 subfolder under the path in two i’m the owner and the other are owned by gdm.
- one name folder start with C-hostname-1001-…..
- the rest of the others folders is named with F-C-hostname-1001-….
This five folder correspond to five issue? Within the folders i need to check the session file for the errors?
– Is trying to connect with a Windows 10 Workstation to an Ubuntu VM using NoMachine. He is able to connect with the Ubuntu VM with the NoMachine Player, but when he try to authenticate in Ubuntu no way to login.
i’m new on the NoMachine so just to have a first good connection we needed to change some file in the
- Uncomment the following row WaylandEnable=false in the configuration file /etc/gdm3/custom.conf and restarted the service
- Uncomment the following row PhisicalDesktopAuthorization 0 in the configuration file /usr/NX/server.cfg and restarted the service
- If i try to connect to the VM with my account from my Windows 7 Workstation i don’t have problems apart some strange behaviour during the login phase. Whe he tried form his Windows 10 Workstation
I tried to connect via VMware Console and the problem is the same, probably i need to reboot the VM after disabling Wayland, and restarting the service is not the enough?
