Unfortunately: no luck
I use windows remote desktop to connect to the linux computer. On this I have xrdp running and tightvncserver installed. When I uninstall tightvncserver and install x11vnc, I can't get a connection with remote desktop. TigerVNC can't even be located. (Note that I run arm64 not armhf on my rock64. Maybe there's no arm64 version of tigervnc?)
I have now uninstalled vnc servers and reinstalled tightvnc. remote desktop allows me to start a session, but the keyboard is still messed up in kstars. Ie back to square 1.

I have always had issues with TightVNCserver and the keyboard.
I suggest you reinstall x11vnc and on the PC connect to it with a VNC client, not RDP. They are not the same thing.
You may have to do some configurations to setup x11vnc server for start on launch, passwords, etc.

Can you recommend a good/stable vnc client for windows 8?
I just defaulted on rdp because it worked (so far)

I just use the RealVNC viewer.

I downloaded this and the tightvnc viewer for windows. But I still have issues getting this to work. Tigervnc doesn't seem to have an arm64 version. x11vnc installs, but I'm having trouble connecting. Have to figure out the exact cause. It could either be a firewall setting or some services colliding.

I had an issue that sounded similar. I needed to run locale and locale-gen. Perhaps this may help.

Thanks again.
Of course I run my machine headless, so there is no session to view. Fortunately the first link you provided contains information regarding this.

Wim,

Please post back if this works for you. I have had to recreate my Rock64 and followed such directions. VNC worked, yet I was unable to get Ubuntu to find a different resolution (traveling right now so cannot say what resolution is the default.) The caveat is that I am using the xenial armhf image for the rock.

Even though I thought I saved my instructions, I cannot get the headless Rock64 to use the dummy xorg video driver after a dust-upgrade. Fortunately I have a backup image I can use.

Thank you.

Maudy:
You can configure system resolution in the /boot/config.txt file
elinux.org/RPiconfig
For example adding / uncommenting the relevant lines in config.txt. In my case
Custom Hotplug Display
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=28
This represents the 28th configuration in group 2, or 1200x800 at 60hz

Make sure to set hdmi_group to 2. The other day I set it to 1 and didn’t get a display on my monitor.

Note to self:
I uninstalled all vncservers I could find, as well as xrdp
Then reinstalled xrdp and vnc4server (one of the recommended support packages). This had the following effect
- the keyboard problem in kstars was solved
- starting ekos with simulators froze the ekos screen after it had started an instance of indi. There may have been a message window behind the ekos window that caused this. i could drag windows across the desktop, but they were just not responsive when clicked in.

Uninstalled vnc4server and xrdp and reinstalled xrdp
Installed tightvncserver. The keyboard problem was back, but kstars and ekos worked flawlessly, no unresponsive windows.
