Problems with NetworkManager on KDE

Hey guys.
I'm using NetworkManager on KDE, sometimes after using NetworkManager applet for connecting to or dissconnect from a network (wireless network, VPN connection, ...), I can't run any new application from anywhere! sad

If I run an application from the launcher nothing will happen.

Launching new application by keyboard shortcuts:
139730354120541.png

From terminal:

[matrix@localhost my-app]$ firefox
(process:3583): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
No protocol specified
No protocol specified
Error: cannot open display: :0

[matrix@localhost my-app]$ konsole
No protocol specified
Segmentation fault (core dumped)

[matrix@localhost my-app]$ chromium 
No protocol specified
(chromium:3588): Gtk-WARNING **: cannot open display: :0

[matrix@localhost my-app]$ dolphin 
No protocol specified
dolphin: cannot connect to X server :0

Everything become ok after logout or restarting kdm.
Here is some information, maybe helpful:
Installed packages:

networkmanager libnmqt kdeplasma-applets-plasma-nm intel-dri lib32-intel-dri libva-intel-driver xf86-video-intel mesa mesa-libgl lib32-mesa lib32-mesa-libgl

uname:

Linux localhost.localdomain 3.14.0-4-ARCH #1 SMP PREEMPT Wed Apr 9 21:11:25 CEST 2014 x86_64 GNU/Linux

KDE Version: 4.12.4
Intel Ivy Bridge GPU on a Asus X451CA Laptop

Any ideas?
(Sorry for my bad English)

Re: Problems with NetworkManager on KDE

Is this a rather fresh setup? Do you notice this behaviour from the beginning or did it start somtimes after the initial setup? If yes, do you remember when it started and can you maybe connect the time the behaviour started to some updates or new software installed? Is there a network connection established when this problem occurs?

Re: Problems with NetworkManager on KDE

This is a fresh setup. I installed Arach Linux on my new laptop ~ 1 month ago and I had this problem from the beginning.
This problem usually occur when sometimes elapsed from the login and if I use NetworkManager applet immediately after login, usually everything is ok. and network connection will establish successfuly in both (with or without the problem).
While the problem occurs, running applications work fine, but i can not run new applications.

Re: Problems with NetworkManager on KDE

I was hit by this problem on two different laptops too. It looks like a change of the hostname may be the cause of this problem, see here for some more information:

http://forum.kde.org/viewtopic.php?f=66 … c&start=15

I forgot to set /etc/hostname on both laptops and it looks like you didn't either. Maybe networkmanager will set a different hostname based on dhcp if none is set, as indicated in that post.

I could not verify that this is really the case, since I can't reliably reproduce the issue. However, setting a different hostname on the fly using 

sudo hostname eggsandspam

will immediately trigger the symptoms and prevent KDE from starting any application.

The laptops have now a hostname set in /etc/hostname and so far everything runs smoothly.

Edit: I just looked at your logs in detail. See this line:

Apr 14 10:09:11 localhost.localdomain NetworkManager[260]: <info> Setting system hostname to 'localhost.localdomain' (error starting hostname thread)

NetworkManager did change the hostname. That line is visible in the logs of my laptops too.
