In this vein...I am having a problem with VNC that perhaps someone can
shed some light on.
After reading the an article in the Linux Journal magazine - which I've
saved for quite some time, I wanted to set up VNC so I can have a
continuous session going, whether I am on the localhost or one of the
other machines around my house (yes, it's decadent but I figured, the
learning experience would be good).
The article is online <[EMAIL PROTECTED]>
I am using RH 8
The problem that I ran into is this...
I changed /etc/init.d/vncserver as follows...
from
"su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver :${display%%:*}\""
to
"su ${display##*:} -c \"cd ~${display##*:} && [ -f
.vnc/passwd ] && vncserver ${ARGS} :${display%%:*}\""
and changed /etc/sysconfig/vncservers by adding a line...
ARGS="-geometry 1024x768 -alwaysshared "
all per the article...
When I try to start vncserver (service vncserver start), I get an error
that it can't find the file which I am certain is -geometry 1024 x 768
-alwaysshared instead of using those as arguments to the vncserver
command within /etc/init.d/vncserver
I have tried various combinations...i.e. removing -geometry 1024x768 and
by removing -alwaysshared and even deleted the ${ARGS} and replaced it
with -alwaysshared and the same error occurs...
Is anyone doing this? Does anyone see the cause of the problem?
AND
If I log in locally and then log out...then any application that I used
locally will give me an error if I try to use it via VNC -
(KDE) - KLauncher could not be reached via DCOP
and vice versa - if I use an application from remote VNC Connection and
close the connection, I get the same error when I log on locally and try
to launch the application.
Thanks,
Craig
