[opensuse] Headless X-Server ?
Hi, how can I configure a headless X-Server ? The PC should provide graphical logins from outside, e.g. VNC, but it shouldn't change into graphic mode itself even in runlevel 5. Motivation: Opensuse 12.1 has issues with the onboard graphics, even though older releases work. So either the driver doesn't support my rather common AMD chipset or the chip is damaged. Textmode works btw. Because I don't sit berfore the machine often it was sufficient that it supports VNC. As soon as it changes to graphic there are distortions and the mousepointer is frosen. VNC works anyway, though. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Either; 1) Edit /etc/inittab and change 5 to 3 as show below; # The default runlevel is defined here id:3:initdefault: or 2) Computer -> Yast -> System Services -> Expert Mode -> Uncheck 5 -> OK! Most, if not all services (with the exception of gdm/x) run in level 3 and 5 so you should not loose and functionality from the system. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Note that this doesn't apparently work on 12.1, as systemd uses a different method to set the default runlevel.

And /etc/inittab has a comment about the change: # The default runlevel for SysVinit is defined here # please note that for systemd the symbolic link # /etc/systemd/system/default.target has to relinked # to e.g. /lib/systemd/system/runlevel3.target Cheers Lars -- Lars Müller [ˈlaː(r)z ˈmʏlɐ] Samba Team SUSE Linux, Maxfeldstraße 5, 90409 Nürnberg, Germany

VNC connection from a remote desktop should work with runlevel 3 on your system. -- Arun Khan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hardly even that. I have a headless Dell machine acting as a server under my desk. I can ssh to it and run GUI applications. No need for a (possibly insecure) VNC server running there. -- If God does not write LisP, God writes some code so similar to LisP as to make no difference. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

What are you using as client? In my case it's Windows so VNC is an easy option. When I connect from outside the LAN I use a ssh tunnel so I expect to be fairly secure. On the other hand VNC is rather crap in details like where is the cursor in the text editor. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

there are quite a few windows ssh clients; putty works well but if you have admin authority and some extra space on the windows machine, it might be worth your while to look at cygwin. it basically creates a unix like environment under your windows instance. a little playing and tweaking and you'll even have native X on windows, allowing you to run applications from your headless machine but displayed on your windows machine. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I noticed on the openSUSE 12.1 install DVD, in dosutils/weirdx, lives an X server for, presumably, Windows. Not sure what it is there for. Or how one would use it. There are docs there for the curious.

SUSE installation media have had windows/DOS utilities for a very long time. The reason is that you can install suse remotely while still having a GUI installer (e.g. by using the boot parameters "vnc=1 vncpassword=<some password>") and since there is no vnc client included in a standard windows installation, it is provided to save some troubles for the regular windows user who wants to install a server Anders -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I do not believe Putty contains an X server. Its a pure ssh client. If you want X, you have to add another application to your windows box. Google will find several for you.

What else do you suppose he meant when he said you can install cygwin and use it's X server? -- bkw -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

That it allows forwarding X11 connections is not the same thing as an X server. Forwarding is nothing but TCP packet handling. Install Putty on a virgin Windows machine and ssh into your Linux box and run something as simple as Xeyes. No go. Further: X Client = where your applications run X Server = where your applications display. -- _____________________________________ ---This space for rent--- -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

... are you certain it's not just forwarding to your local X server? I tried the windows implementation and it doesn't seem create it's own X server. it kinda looks from the man page that you're running putty on a unix/linux machine and might already have X running local? I'm pretty sure on tthe windows side you'd need something else to get all the X features, be it cygwin, exceed (do they even still exist?) or some other paid for or freeware server. -- Even the Magic 8 ball has an opinion on email clients: Outlook not so good. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I believe that means it supports X forwarding over ssh, in the same manner as you'd use ssh -X. However, you still need an X server. There is one included in Cygwin, but I prefer Xming. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Have you thought of FreeNX and use the free client for Windows from Nomachine? It works in run level 3 DC -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
