No, you don't have to touch that, it works with no change.
Sorry to disagree, but I only discovered the configuration variable after SuSEconfig had changed it back several times (take a look at the guilty code in /sbin/conf.d/SuSEconfig.xdm root@k6:~ # grep -5 nolisten /sbin/conf.d/SuSEconfig.xdm check_md5_and_move $file else echo "${0##*/}: change of $file skipped" fi if test "$DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN" = "no" ; then sed "s/\(.*\/usr\/X11R6\/bin\/X\)[ \t]*\(-nolisten[ \t]*tcp[ \t]*\|\)/\1 -nolisten tcp /g" < $file > ${file}.SuSEconfig check_md5_and_move $file elif test "$DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN" = "yes" ; then sed "s/\(.*\/usr\/X11R6\/bin\/X\)[ \t]*-nolisten tcp[ \t]*/\1 /g" < $file > ${file}.SuSEconfig check_md5_and_move $file else echo "${0##*/}: change of $file skipped" fi fi
And I also have acceptable performance with X over ssh, precisely because it DOES compress the transmission. On local networks, or fast wide area networks its actualy faster than running locally because you have two processors involved. All the hard work for X is offloaded to the machine where you sit, and all the other work is done on the remote machine.
To give ssh and KDE their due, I tend to keep using computers which most people would consider obsolete, and 9.1's KDE is right on the edge of needing to be replaced by something faster on my "antiques" :-)

Perhaps I misunderstood... I thought you were saying you had to change that line in /etc/sysconfig/displaymanager in order to forward X over ssh. Perhaps you meant that change was necessary for a remote xterm NOT using ssh. (Meby so, I never tried that). You don't have to make that change to run X over ssh. Mine still says this: # # Tcp port 6000 of Xserver. When set to "no" (default) Xserver is # started with "-nolisten tcp". Only set this to "yes" if you really # need to. Use ssh X11 port forwarding whenever possible. # DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN="no" And yet I can open an xterm over an ssh connection just fine, but it won't listen for a remote connections on port 6000. -- _____________________________________ John Andersen
A short explanantion is in order here... Since you seam to be missing an small piece of the puzzle.... 8-) SuSe has forseen your need and prepared thier scripts to allow you an easy way to change the values.... go to yast->system->/etc/sysconfig editor. there search for DISPLAYMANAGER Select the "$DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN" set to yes, Click Finish... Now not only does it work, but the value will be correctly use after each update, and SuSE will try (they make no garuntees) to keep this implemented in new version of XWindows as well. SuSE is your friend an helper, if you let them.... Jerry On Sat, 2004-05-29 at 09:16, John Andersen wrote:

I use ssh -X constantly and it works really well. SuSE 9.0. -- Jim Sabatke Hire Me!! - See my resume at http://my.execpc.com/~jsabatke Do not meddle in the affairs of Dragons, for you are crunchy and good with ketchup.
