Unable to run kde or gnome

[Martin, Larry D]

I have installed Debian (2.6.32-5-s390x Sun Sep 23 08:59:07 UTC 2012) on a z9 - LPAR mode.

I can login but cannot get either gnome or kde to work. Whenever I issue startx, I get:

xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory).

I have tried to research this via Google but have not found any answer that works. In /dev I do have a tty but no tty0.

Also, what editor do I have available in line mode?

Thanks, ..........Larry

I had a suggestion to run vncserver and I can try that (once I figure out how). What I really want to know is how to fix the 'startx' so that it works.

I think I need to update the config file, but with what? When I type startx I get the following:

I have installed Debian (2.6.32-5-s390x Sun Sep 23 08:59:07 UTC 2012) on a z9 - LPAR mode.
xf860OpenConsole: Cannot open /dev/tty0 (No such file or directory).

On what graphical console would you expect X to appear? z doesn't have any.
All you can do is using some kind of remote desktop, but not through startx.

Kind regards

I have logged on through Putty from my desktop. Are you saying that because
Debian is running on the Mainframe there is no graphical interface available?

No Linux system supports startx over putty. You can install GNOME or KDE and
run it via X forwarding or xdmcp or VNC. But that's all not s390-specific.

Kind regards

Any idea why startx will not run. If I run it as root I get all the messages
I posted earlier and if I run it as a user I get that I am not authorized.
When I type gdm3 all I get is repeated messages about the display running for
0.2nnnnnnn seconds and have to <break> to get out of the loop.

As I said it's not supported. I don't know what else to tell you. There's
nothing startx could draw a display on. gdm/xdm/kdm needs an xdmcp
configuration before they can be used. Xnest seems indeed one way to go.
Another one is vncserver.

But I already said all of that (granted, except Xnest, thanks for the hint.)

Try startx on any x86 Linux box. It might start an X session on VT7 if you're
root, but not in your Putty.

(That question is not s390-related, so debian-***@lists.debian.org might be a
better fit for support.)

Kind regards

Thanks to all. I have VNCSERVER working. Now to see what productive things we might be able to do.

Thanks, ...........Larry
