--- this is a repost of a previous message, with a couple of added
--- preliminary "answers" to expected questions.
If you read my previous message, the added info is here, until the
full "---" line (some other corrections to the original message were
made, so that if you have the patience, and wish to help, please re-
read):
4. vncconfig is running
5. the xorg.conf file includes the following lines for vnc.so:
Load "vnc" # VNC server hook
Subsection "vnc"
Option "Desktop" "Pete's Workstation"
Option "SecurityTypes" "RA2"
Option "RSA_Private_Key_File" "/root/.vnc/private.key"
Option "UserPasswdVerifier" "VncAuth"
Option "PasswordFile" "/root/.vnc/passwd"
Option "IdleTimeout" "600"
EndSubSection
6. various settings of of "CompareFB" "on" vs. "CompareFB" "off",
Option "deferUpdate" "40" or "0" or "20" or "60" or "100", produced
no difference.
7. yes, I restart the X server after each such change to xorg.conf.
8. VNC-enhanced X server desktop resolution is 1152 x 864. The rez
of the Windows 2000 desktop on which vncviewer is running is
1024 x 768.
9. network (LAN) is Ethernet 100Mbps. Access is through the LAN.
...
More generally, refreshing of the vncviewer window is not complete
in many situations: e.g. if I move a window, the background in the
area that the moved window occupied originally, does not get always
repainted in the vncviewer window.

Complete message (original plus additions) follows:
I am trying RealVNC 4.2.5 for remote administration of Linux boxes.
All our Linux boxes run Fedora 4, and will upgrade to Fedora 5 soon.
This is my problem with RealVNC 4.2.5, when interacting with the
display :0 of a target machine (Fedora 4, with X updated to the
latest release as of today, xorg-x11 v6.8.2 Release: 37.FC4.49.2.1
and all the associated xorg-x11 packages updated to the same level)
when viewed with vncviewer RealVNC 4.2.5 from a Windows 2000 desktop
(also completely up-to-date):
Shell windows (black bg with white or color fonts) are not refreshed
in the vncviewer window, neither when typing from vncviewer nor when
typing locally on the server desktop. If I move the window, kinda
"forcing" the shell window to be redrawn in the vncserver window on
Windows 2000, then I see the typed input. If I move the mouse making
the pointer go over the not-refreshed areas, they get "repainted" and
then I can see them. It does not matter whether I start the shell
window or other application (Netscape, e.g.) from the native desktop
or from the vncviewer client - the results are identical.
Trying gnome-terminal and xterm produce the same result.
The titles of the window do not show initially, until I move the
window (drag it).
Other editable windows or fields, refresh or don't refresh, following
some "rule" that I can't figure out:
- the address line of a Netscape 7.2 broswer does not refresh
- the text area of a gVim editing session, refreshes perfectly.
More generally, refreshing of the vncviewer window is not complete
in many situations: e.g. if I move a window, the background in the
area that the moved window occupied originally, does not get always
repainted in the vncviewer window.
It appears to be a vnc.so problem because x0vncserver refreshes alright.
It is far less efficient than the vnc.so module though.
To avoid obvious questions and answers, I will post the following answers
here:
1. I tried the client vncviewer against other RealVNC servers (Linux
vncserver/Xvnc and x0vncserver) and the problem does not show: the
input keystrokes get reflected immediately on the vncviewer window.
2. I tried the client vncviewer against Windows RealVNC servers, and
it works ok. It is not a problem with the Windows vncviewer.
3. Only when the server is a Linux X display, with the vnc.so module
from RealVNC installed and running (I can connect alright, with or
without encryption, with this authentication method and the other,
etc. --> no connection problems) that I find this problem
4. vncconfig is running
5. the xorg.conf file includes the following lines for vnc.so:
Load "vnc" # VNC server hook
Subsection "vnc"
Option "Desktop" "Pete's Workstation"
Option "SecurityTypes" "RA2"
Option "RSA_Private_Key_File" "/root/.vnc/private.key"
Option "UserPasswdVerifier" "VncAuth"
Option "PasswordFile" "/root/.vnc/passwd"
Option "IdleTimeout" "600"
EndSubSection
6. various settings of of "CompareFB" "on" vs. "CompareFB" "off",
Option "deferUpdate" "40" or "0" or "20" or "60" or "100", produced
no difference.
7. yes, I restart the X server after each such change to xorg.conf.
8. VNC-enhanced X server desktop resolution is 1152 x 864. The rez
of the Windows 2000 desktop on which vncviewer is running is
1024 x 768.
9. network (LAN) is Ethernet 100Mbps. Access is through the LAN.
Anybody had this problem? what is the solution?.
Thank you in advance, and many regards.
-Pete
