problem using rdp or vnc remote access when no connected monitor to device

[rosen enev]

hi all,

i see  that my board is not supported LinkStar-H68K-1432 V2  but i think the problem is general about gnome-remote desktop

i have:

in  gnome-remote desktop  I allow vnc and rdp remote access

i can access to  desktop in this device and have a session but when i switch off the monitor sessions a closed

 

 

may be missing configuration for dbus access control?

 

[rosen enev]

does  anybody have such problem?

this was a common issue for gnome 3 : can not use intergrated rdp or vnc in headless mode

i switch to xfce + nomachine

other way is to use hdmi dummy pin

Since your platform seems to be an rk3568 and very recent at that, could it be it runs Wayland instead of X11 by default?

That could explain some of the VNC troubles (search "rpi5 and vnc" or basically "bookworm and vnc")...

 

And could the RDP troubles be based on the same problem (Wayland)?
