The only thing I see when I connect is the “User max connected” popup from nomachine, it appeared at the top left of the screen for some reason and not the bottom right where it should be. This is debian 8.5 but it illustrates the popup I refer to:

Despite everything being black I could click and close the popup so it seems I was in fact connected. I am connecting from nomachine on a windows 10 64 bit machine.
I tried disabling the firewall and app armor (yeah I know both are bad ideas in the long run but I had to try something to get to the cause!). The only thing I found that made it work was plugging an HDMI cable into the TV that sits near the server. Even though the TV was turned off, nomachine worked with no blank screen. This is not a permanent solution however as my TV only has 2 HDMI inputs and both are typically in use.
I really want to use opensuse leap on my home server, its a very impressive distro overall and has earned a place on my laptop. But I cannot use it unless I can get nomachine working.
Any ideas why this happened or how to fix it?
I dont wanna bump my own topic but I cant seem to edit my post. This is *exactly *what I get:

VNC is the same, obviously without the login popup.
Here its been suggested that the graphics card stops working when the cable is unplugged:

I have tried the solution (disabling sddm as kde5 dosent seem to use lightdm display manager) but it didn’t work unfortunately. I get the same blank screen. I briefly saw the opensuse logo and loading bar but I think thats just because I logged on quickly, still no desktop or icons or anything.
Any other ideas?
Am a bit confused is this a headless install What video card and driver?
Its a regular install with a DE but no monitor attached. I want to administrate it with a GUI using nomachine, I do too many varied things on the server to do them all with the command line.
i915 driver:
Thats the chip in it:
http://ark.intel.com/products/77773/Intel-Pentium-Processor-G3220-3M-Cache-3_00-GHz
Intel just calls it “HD Graphics”
Ok that means it is headless ie no monitor. Seems like the driver or video shuts down if no monitor. The video stack is needed to render screens with most remote solutions. As an experiment try booting with nomodeset option. You can add that as a kernel boot option in yast. Then shut down disconnect screen and reboot. Get a GUI bby remote? nomodeset will force a fall back driver. If still no connection then it could be a hardware issue. But this is all pure guess have no way to test her since I don’t use Intel. Perhaps there is a plug that can trick the system into thinking the monitor is attached???
YES!! That did the trick, thank you so much!!
I guess the much older intel driver in centOS and debian dont have this issue or simply behave differently.
In case anyone else has this issue:
go to yast
go to bootloader
go to kernel parameters then add “nomodeset” to the optional kernel command line parameter field
mine looks like this “resume=/dev/sde2 splash=silent quiet showopts nomodeset”
