How To Open An Xnest Window And Login

carney1979

Use this command:

Xnest :1 -query localhost -ac

This will open an Xnest window and display your login manager (kdm, gdm, xdm, etc).

You can then login as yourself (again), or let another user login "real quick" so you don't have to end your session.

Nice tip,

but I'm having some problems. The new login window is black, no nice login screen

The mousecursor changes to the ugly X when move my mouse over it, so it seems to work otherwise...
I'm using XFce4 with GDM as my login manager.

Edit: o_O I'm not n00b any more...

Forgive me...I've been working on this since last night :wink:

Find your gdm.conf (gdmrc, or whatever). You might even be able to change it with the gui gdm config program.

You must enable XDMCP.

That should do it. Sorry, I use kdm here so I can't tell you where your gdm config file resides.

Yes, you needed to stop and restart xdm (gdm).

Not sure with Gentoo, but with some Linux's you can login to a (real) tty as root and first give an:

init 3

...then after it all stops:

init 5

This stops, then restarts X, xdm(gdm), etc.

I knew there had to be a 'Linux' way to do it

Is there a nice gnome gui for loggin in using xdcmp? I used to have the option in gredesktop or some similar app a year ago but never used it. I now have a new machine and it appears that gredesktop only has the windows terminal server option no vnc or xdcmp option.

I just read your tip and just can't understand how is this different from having your (g/k/x)dm start on multiple screens (:0,:1, etc), and then switching between them when you need to start a new session without closing the current one.

There's even a link (in kde it's called 'Start a New Session', I don't know about gnome) that helps automate that.

Also, doesn't the '-ac' option just disable security in your X?

Cheers,

Not sure if you are talking about my tip in another post but I am looking to launch an x desktop from a remote machine on a local machine. Basically llinux's version of terminal server. I have also seen the ltsp but its a bit of an overkill for what I want at the moment.

Hi xmc !

Sorry if my post confused you. I was talking about carney1979's tip which he started this thread with

About logging in remotely to X. I think you're talking about a 'chooser' (no sure though if that's what you mean). It's a little screen that shows you icons with X11 hosts on your network and takes you to the DM on the one you choose.

It comes with XDM, and if I remember well (I don't use gnome anymore) there's an equivalent (with much better look) that comes with GDM.

Apologies if you already know all of the above and was talking about something else

Cheers,
