Hi all,
I am brand new to the Unix/Linux world, just started taking the
plunge. First of all, please forgive me if this is not the
appropriate place to ask such questions...
I just installed Fedora Core 4 and have been playing around with it
for several weeks now. I also have a Windows XP machine connected to
the same router as the linux box. I'd love to be able to do
everything from one machine, therefore setting up an X server on the
windows box to run X programs and have them appear on my windows
machine. I downloaded Xwin32 and have been able to do what I just described.
However I'd like to take it to the next level and be able to popup
the entire KDE desktop on my windows machine. I believe that the way
to do this is using XDMCP, and then Xwin32 is only remotely managing
the KDE session running on the Linux PC. However, upon trying to use
the XDMCP option in Xwin32 to connect, my entire Windows desktop
turns grey, with a slightly linux-y looking mouse pointer, but
nothing ever happens. I need to Alt-tab to get back to any of my
other windows programs. Has anyone ever seen this before?
A few things:
1. In the KDE Login settings (I believe that runs gdmsetup), I've
checked "Enable XDMCP" on the XDMCP tab (I'm using the SAMS Red Hat
Fedora 4 book and it led me to believe that this is all I would need to do).
2. I've edited /etc/X11/xdm/xdm-config to comment out the line
"DisplayManager.requestPort: 0". I added a "!" in front of that line.
3. I've edited /etc/X11/xdm/kdmrc to change the line "Enable=false"
to "Enable=true" under [Xdmcp]. Both this step and step 2 I found
from various internet postings and thought I'd give them a try.
4. On my network, my windows PC gets a dynamic IP address from my
router and I configured the Linux machine to use a static IP. I've
set up Xwin32 to connect to Linux using it's IPaddress, and the
Xwin32 configuration specifies the IP address of the windows machine
to route its display back to. Both machines can only ping each other
using their IPaddresses, not hostnames (I've nothing set up in the
host files for either machine).
Between each configuration steps 1, 2 and 3, I restarted the Linux
machine (the postings mentioned restarting just X, but I didn't know
how to do that. They actually mentioned restarting the X server, but
that didn't make sense to me. Isn't the Xserver what is running on
my Windows PC, but I made the changes on the Linux side? I thought I
would need to restart whatever is running on the Linux side, is that
referred to as the X client?).
Well, that's really it. Have I missed a magic step somewhere along
the line, or is the problem more complicated, related to my
hardware/firewall setup perhaps (I tried this while disabling my
Windows firewall, no luck)? At this point, I'm not really sure if
the issue is the Linux configuration, my network or the X server
configuration on my PC. Maybe a different X server (CygwinX
perhaps?) would give me better luck?
Sorry if this is such a basic thing, I really am just barely starting
to figure this thing out.
Thanks, any help would be appreciated!
