VNC Black Screen

[tolekutma]

VNC Server
XBian version: Xbian 1.0 (knockout) Kernel: 3.18.8+
XBMC/Kodi version: Kodi 14.2-RC1
Overclock settings: Default

Hardware
RPI 2

Problem description:
I am using vnc server.
Connecting VNC viewer give me black screen only.
(usign the the TV it seems that cursor is working over the VNC )
Googling lead me to many option that are all relevant to changes in ~/.vnc/xstartup.
I didn't find xstartup file in my xbian.


How to reproduce:

I had exactly the same issue here (black screen on VNC client)

The solution was (after some googling):

1. Don't expect too much, the VNC server is slow
2. Reduce your resolution in Xbian, by adding the following two lines to your /boot/config.txt
(i.e. run sudo nano /boot/config.txt)

hdmi_group=1
hdmi_mode=4

3. Play with your VNC client settings. Hextile worked better for me. Color depth might help too.

Personally this works so badly, I find it's only good for debugging issues while in a different room (i.e. in bed)

Good luck

It seems very fussy - so try play with your VNC client settings until it shows up.

And it's really killing my CPU - 94%

tried this solution with hdmi_mode in config.txt but still doesn't work. as soon as network interface is up, vnc server can be reached and it keeps streaming video (splash screens) until kodi is started. from that moment forward, only black screen on client side. vnc service restart doesn't help. If I remove HDMI cable from RPi 2, everything works like a charm.

are there some setting in vnc server that can be changed and where they are located?
