[Fixed] Mageia 6 Control Center crashing.

[nemmie]

After I switched over to NetworkManager, I have been having a problem with Mageia Control Center no opening or opening an then crashing.
So when I first reboot my computer I can open MCC and so some things, but soon it starts telling me when I trying to open anything inside it
just says the application crashes. Then if I close MCC and try to reopen it I get the password request screen, I type in my password hit enter
the password box goes away but no MCC. So in console, I type in MCC I get promped for the password in a gui box type in the pass. the box
closes and I get this in console

Code: Select all

mcc
Too late to run INIT block at /usr/lib/perl5/vendor_perl/5.22.2/x86_64-linux-thread-multi/Glib/Object/Introspection.pm line 257.
Ignore the following Glib::Object::Introspection & Gtk3 warnings
No protocol specified
Unable to init server: Could not connect: Connection refused
Cannot be run in console mode.


So if I run sudo MCC I get the password promp, enter my pass and I get the blue mcc in Console. some things will work, others give me

Code: Select all

sudo mcc
Too late to run INIT block at /usr/lib/perl5/vendor_perl/5.22.2/x86_64-linux-thread-multi/Glib/Object/Introspection.pm line 257.
No protocol specified
Unable to init server: Could not connect: Connection refused


I am at a loss for what I did wrong, can someone show me how to fix this please

At the very least please provide the output of the following commands, run as your regular user in a terminal:

Code: Select all

loginctl show-session $XDG_SESSION_ID
ps -ef|grep -v grep|grep -iE "polkit|policykit"
pkexec whoami     # you need to enter your root password when asked by the authentication dialog
echo $DISPLAY

and as root from:

Code: Select all

systemctl status polkit.service -a

This would be required once for an occurrence where MCC starts fine, and once for an occurence where it doesn't.

You forgot to add the context information if it worked as expected or not, and you would also need to add the second set of outputs, as mentioned previously:

This would be required once for an occurrence where MCC starts fine, and once for an occurence where it doesn't.

I have been trying to get a working session of MCC. Seem now it is not wanting to work at all other than in command line mode. But as soon as I do, I will post

[nemmie]

Ok so I have nailed down my problem
When it switches to unknownb8ee653359a3.attlocal.net is then my MCC stops working
This all started when I started using NetworkManager. So I am guessing NM is overwriting my local hostname and how do I stop this?

So I am guessing NM is overwriting my local hostname and how do I stop this?

Well if you obtain your hostname via DHCP then that is normal, and the X authorisation is tied to the hostname. And it seems you don't have a local hostname set.

You should probably just set a static hostname locally, using e.g. manahost or hostnamectl if you prefer commandline.
See e.g. http://centosfaq.org/centos/prevent-net ... -hostname/
Maybe for your setup it might even be sufficient to set the hostname in /etc/sysconfig/network as mentioned in the link.

For reference, this is already reported as https://bugs.mageia.org/show_bug.cgi?id=3782 and https://bugs.mageia.org/show_bug.cgi?id=18077

I went into /etc/hostname and set my name. I hope this fixes my problem.

Ok, so it has been a while now and I have not had any problem. In recap, I was having trouble opening Megia control panel. tracked it down to, when I would start my session pam would see that my computer name as local.localhost. then when I would connect to my wireless network or any network, the network was assigning my computer a name like a12344w@something.com. then when I would go to open control panel, pam would see that my new computer name was not right and deny access to the control panel. Setting my computer name so it stayed the same fix this issue. I set it in hostname. This fix it for me.
