VNC - CentOS 7 Server login screen refresh preventing authentication


  • TigerVNC 1.4.1
  • CentOS 7 Server on Intel 64 bit
  • vncViewer is running on Windows 7 & 8.1
  • Using both TigerVNC and Tight VNC viewers
The CentOS GUI login screen appears with the correct (su) user name. The screen refreshes ~ twice per second allowing only one character to be entered in the Authentication box before refreshing. I am unable to login remotely via VNC. PuTTY access, etc., works fine.

Personally if i was forced to use vnc, i have always preferred x11vnc as it gives you an actual console rather than a virtual desktop.

on a side note, you should look into tunneling vnc over ssh assuming it's still inherently insecure as it historically has been.

Alternative to VNC?

What you recommend as the preferred method to remotely view the CentOS desktop from Windows?

i have 4 recommendations:

noMachine v4 - presents actual console
xRDP - presents virtual desktop and may need theming/x11 config
TeamViewer - presents actual console ; accessible over internet
x11vnc - presents actual console

i use multiple solutions on my workstation. i use either x11vnc(over ssh) or nomachine on a server.

KDE Plasma crashes with TigerVNC

Thank you for your advice. We are familiar with TeamViewer and will also try xvnc.

I found a directly related issue on the TigerVNC-Users group. TigerVNC crashing with KDE Plasma. I discovered this issue on our CentOS server as well.
