Can not enable VNC server even if it seems to be, can be caused by TightVNC?by

Wed Jun 05, 2019 5:26 pm

I made the worst mistake to install TightVNC to use remote desktop from my laptop that is by default installed. I didn't know that VNC is much better but when I installed it on some tablets I saw that it doesn't create another desktop but accesses directly the existing one, so I can see exactly what happens on a monitor or TV directly connected to Raspberry. This is great. I installed on laptops VNC and I can connect to one of my raspberry. On the other Raspberry I installed TightVNC.

When I try to enable the VNC into the configuration menu, it looks like it is already enabled but the radio-buttons can not be used. I can not change, this option itself is disabled and grayish.

I know this problem was debated earlier but may be somebody knows a quick fix now without reinstalling the OS. I have a lot of work and libraries installed now and I do not have time to reinstall everything in this moment. Can be the TightVNC the culprit? I installed it to use remote desktop. But the Raspberries already come with VNC by default to use with VNC viewers from all possible tablets, phones or laptops.

If you want to try to revert to the default vncserver with Raspberry Stretch, try installing realvnc-vnc-server and realvnc-vnc-viewer.

I contemplated installing tightvnc when I thought my Pi Zero vnc sessions were slow due to Real VNC server. When I saw that it seemed to want to remove the existing vncserver, I decided not to because I'd have to fiddle with a window manager.

Turned out the slowness was just the Pi Zero wanting to be rebooted.

Real VNC will work with tightvnc and vice versa. I use Real VNC viewer on my Windows PC and tightvnc on my C.H.I.P.'s (a now defunct competitor to Pi Zero W).
