Hello  
I have a problem with VNC. I have a Suse Linux Enterprise Server 12.3 and when I run the vncserver command in the log I have the following error

[CODE][I]Tue May 8 14:32:13 2018

The result is that when I try to open a vnc client I have a black screen.  
Can someone help me to debug the problem?  
Thanks

Since you have posted in a forum for issues relating to SUSE Linux  
Enterprise Desktop (SLED) with a prefix of “SLED 12 SP3” please  
can you clarify whether you are using SLED or SLES12 SP3? Please

How have you configured VNC?

Which VNC client are you using? From which OS?

Hello Simon  
Thanks for your answer.  
Here is the output of the release command

```auto
cat /etc/*release
SUSE Linux Enterprise Server 12 (x86_64)
VERSION = 12
PATCHLEVEL = 3
# This file is deprecated and will be removed in a future service pack or release.
# Please check /etc/os-release for details about this release.
NAME="SLES"
VERSION="12-SP3"
VERSION_ID="12.3"
PRETTY_NAME="SUSE Linux Enterprise Server 12 SP3"
ID="sles"
ANSI_COLOR="0;32"
CPE_NAME="cpe:/o:suse:sles:12:sp3"
```

The only configuration that I made was to change the vnc port.  
I use “VNC Viewer” and “TightVNC Viewer” on Windows 10, and both of them visualize a black screen.  
Regards  
Marco
