Trouble with Mageia Control Center

[gerx]

Hi, I have problem with launching Mageia Control Center. When i try to launch from KDE icon I asked to enter the password but nothing happens. When i try to run mcc from console as user it writes:
"No protocol specified
Cannot be run in console mode."
Only can launch as root in console

[boombaby]

See; now I didn't know you could do that!

When I typed mcc in terminal, it prompted for password, then I got the full-blown Mageia Control Centre GUI to work with. Amazing!

When I exited it, and was left back at the terminal, the following lines were after my command entry...

"/usr/sbin/drakmenustyle" is not executable [Menus] at /usr/libexec/drakconf line 831.
"/usr/sbin/drakbackup" is not executable [Backups] at /usr/libexec/drakconf line 831.
"/usr/sbin/tomoyo-gui" is not executable [Tomoyo Policy] at /usr/libexec/drakconf line 831.

Still got the MCC up though.

This is just FYI.

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

Looks all good. What happens if you run the following as normal user?

Code: Select all

/usr/bin/pkexec /usr/libexec/drakconf
/usr/bin/pkexec /usr/libexec/drakxconf

[gerx]

if I ran drakconf it writes again: "No protocol specified
Cannot be run in console mode."
If I ran drakxconf it asks password and opens simple wndow of mcc in console.

Something seems broken about your X session. Did you maybe change your hostname recently and didn't do a reboot afterwards? Does it happen after a fresh boot, too?
And please show the output of the following commands run as regular user?

Code: Select all

xauth info
xauth list

And please copy&paste the complete command and it's output including the prompt, otherwise you may omit essential information.

[gerx]

Nope, i didn't change it. Maybe it connected somehow but my colleague had a problem with networks so he turned off firewall and changed iptables file
And the output of the commands

Code: Select all

Finally got updates working again. Had to wipe out mirror database and rebuild it using http instead of ftp. Works now but go figure why FTP won't work. Still have problem with MCC gui icon. No response when clicking on it but I can go into a terminal and type mcc and the graphical comes up and works. What do I need to check to fix this? Everything else works off the Desktop.

The " you need to enter your root password when asked by the authentication dialog" is just a comment so do

Code: Select all

pkexec whoami

then

Code: Select all

echo $DISPLAY

[gch3]

Code: Select all

[root@localhost gch3]# pkexec whoami
root
[root@localhost gch3]# echo $DISPLAY
:0

Merged your thread into an existing one for the same issue, in case you wonder.

Output looks fine so far, for now I've no idea why it doesn't start. I'll check if there's a bug for that already reported later.

[DiBosco]

Type this in the command line:

xhost +local:root

I honestly can't remember whether this has to be done as user or root. Try as user first and if that doesn't work, do it as root. That will fix it. I had exactly the same problem and it took a lot of Googling to find someone with a fix. I've since reinstalled due to completely different reasons and that will also solve it.

Sadly, you'll have to do it every time you reboot. I guess you might be able to run it as a startup script somehow.

[gerx]

Thanks!

[doktor5000]

For what it's worth, I've mentioned this issue in the relevant bug report: https://bugs.mageia.org/show_bug.cgi?id=16764

I have recently started facing the same issue. And this was resolved using this solution, running the command as a regular user. Thank you, DiBosco.
