I use Remote login with vnc-ltsp-config with GNOME Desktop Environment on CentOS 5.9. From experimenting today, I managed to get cut and paste working for the session and the login prompt (because I'm lazy and would rather copy and paste difficult passwords).

I created a file vncconfig.desktop in the /etc/xdg/autostart directory which enabled cut and paste during the session after login. The vncconfig process is run as the logged in user.

[Desktop Entry]
Name=No name
Encoding=UTF-8
Version=1.0
Exec=vncconfig -nowin
X-GNOME-Autostart-enabled=true
Added vncconfig -nowin & to the bottom of the file /etc/gdm/Init/Desktop which enabled cut and paste in the session during login but terminates after login. The vncconfig process is run as root.
Adding vncconfig -nowin & to the bottom of the file /etc/gdm/PostLogin/Desktop also enabled cut and paste during the session after login. The vncconfig process is run as root however.

You likely need to re-start VNC on both ends   i e  when you say  restarted VNC   you probably just mean the client  But what about the other end  You likely need to re-start that end too  The root cause is likely a conflict    Many apps spy on the clipboard when they shouldn t  And many apps are not forgiving when they go to open the clipboard and can t  Robust ones will retry  others will simply not anticipate a failure and then they get fouled up and need to be restarted   Could be VNC  or it could be another app that s  listening  to the clipboard viewer chain  where it is obligated to pass along notifications to the other apps in the chain   If the notifications aren t sent  then VNC may not even know that there has been a clipboard update

http   rreddy blogspot com 2009 07 vncviewer-clipboard-operations-like html     Many times you must have observed that clipboard operations like copy cut and paste suddenly stops workings with the vncviewer  The main reason for this there is a program called as vncconfig responsible for these clipboard transfers  Some times the program may get closed because of some bug in vnc or some other reasons like you closed that window       To get those clipboard operations back you need to run the program  vncconfig  amp         After this your clipboard actions should work fine with out any problems    Run  vncconfig  amp   on the client
