I am on KDE 4.1.4, Xorg 7.4 and Linux 2.6.27.10. I am using NetworkManager to connect to Wireless LANs through nm-applet (*sigh*). After launching nm-applet, no other X applications can be started. All apps started before nm-applet still work fine. If I launch a console before nm-applet, and try to start up another X app through the console I always get: user@frodo ~ $ xev Xlib: connection to ":0.0" refused by server Xlib: No protocol specified xev: unable to open display ':0.0' This happens with nm-applet under KDE4 and XFCE (stable). All the gnome-deps are also stable.

Oops. gnome-extra confused me.
Can you please double check if you have your hostname configured correctly? By default networkmanager will change it to the name assigned by your dhcp server, or change it to localhost.localdomain if he won't be able to establish correct hostname. To test it, you can try: 1) Start your system _without_ networkmanager running 2) check your hostname 3) run networkmanager and nm-appet and check hostname The ways to solve it: 1) make sure you've got /etc/conf.d/hostname setup 2) make sure you've got an entry in your /etc/hosts file corresponding to your IP address. You can always create a system-wide connection which will be activated _before_ the X server starts. Can you also post some logs?
You are right - it is a hostname problem. Before I start NM and nm-applet my hostname is "frodo", which I configured in /etc/conf.d/hostname. After I run NM and nm-applet my hostname changes, because the dhcp servers assign different hostnames to my machine (and these hostnames keep changing - depending on my location). When I enter: /etc/init.d/hostname restart everything is working again. I already have configured my actual hostname in /etc/hosts: 127.0.0.1 frodo.home.local frodo localhost So, how can we change this? Is there already a patch or an option for NetworkManager? It obviously is not a very elegant way when X refueses client connections after the hostname changes - so maybe there also is a fix for Xorg?

I will poke Uberlord to see if something can be done with dhcpcd. Personally I don't know any fix for Xorg. Give me a day and I will try to come with something up. Thanks, Rob
OK, I've got some more information for you. Firstly I've noticed you're using 0.6.6, so you should try this (it's elog from ebuild): You need to be in the plugdev group in order to use NetworkManager Problems with your hostname getting changed? Add the following to /etc/dhcp/dhclient.conf send host-name "YOURHOSTNAME" supersede host-name "YOURHOSTNAME" If you decide to switch to NM-0.7 (which I recommend), you can use either dhclient or dhcpcd. To avoid problems with dhcpcd you need to edit /etc/dhcpcd.conf and remove host_name from "option" line. Try it and let me know about your results.
(In reply to comment #6) > Add the following to /etc/dhcp/dhclient.conf > send host-name "YOURHOSTNAME" > supersede host-name "YOURHOSTNAME" Thanks, this hint helped. I just put: send host-name YOURHOSTNAME; supersede host-name YOURHOSTNAME; in the dhclient.conf Anyway - this behavior is really annoying and confusing. I know that it is not a bug in Networkmanager - but why the heck does X refuse client connections when the hostname changes? For me this is just a proof for the bad (or let's say outdated) design of X... I think this bug can be closed - yet we should think about a better way to address this kind of problem. Thanks for your help, Robert!
