I am having a weird problem when running krfb (KDE remote desktop sharing). I can see the initial snapshot of the remote desktop after connecting, I can manipulate windows on the remote desktop with the mouse, but my view of the desktop does not change. It remains as the snapshot of the desktop from the moment I connected it. Basically, it seems that GUI updates are not correctly being transferred to the VNC client.

This is regardless of which VNC client software I uses (TightVNC, RealVNC, etc...) - the behavior is the same.

Any help would be immensely appreciated, because I am completely lost as to why GUI updates are not coming from the VNC server to the client.

I to have had this problem. I think it has something to do with the server because if I connect to an other server it is fine. can you reinstall / install a different server on the remote machine? – cosmorogers Nov 21 '11 at 16:46

I usually suggest an alternate VNC server, x11vncserver or FreeNX.

X11 manpage and download


FreeNX from the FreeNX Team PPA.

sudo add-apt-repository ppa:freenx-team

NOTE: If you do not have add-apt-repository installed add the following

sudo apt-get install python-software-properties

Update Apt

sudo apt-get update

Install FreeNX

sudo apt-get install freenx

I had this problem using vino (ubuntu, gnome, compiz, etc.), and x11vnc seems to me the best-kept vnc secret! The options, the flexibility, the command-line client! I was a bit squeemish about installing a new vnc server, but now I'm enthusiastic! 5 + votes!! – Limited Atonement Feb 10 '14 at 17:38
