Cut the red wire and push the green button.

Really, with that much of information nobody can help you.

We need some details... is it one particular program? Multiple programs?

Sorry, just GUI doesn't start. For examples, mc works. I don't know what I can add.:(

Sorry, SkyTod, I had to sell my crystal ball to get some pungent cheese - yummmm!

You mean the X? Can you post some logs?

I think he means that when trying to start a gui app from the console with sudo, it seg faults. Is that correct?

e.g.

sudo firefox

would seg fault.

That's correct. But I use:

su -
firefox

Because sudo writes that my password is incorrect.:/

You can modify group settings so that you don't have to give password for certain users. Are you using root settings?

I don't need it. I want to start some application as root. It used to work. But now I don't understand what's changed. Nobody faces with something like this?

egrep '^\((W|E)' /var/log/Xorg.0.log

would be helpful.

I type 'su', give the root password, and I am root. Now I can run htop or whatever as root. Never had any problems.

And I. But we are talking about GUI.

karol · 2010-05-20 15:22:33

[karol@black ~]$ su
Password: 
[root@black karol]# firefox

Works for me.

I don't know why you can't run it as root. IMHO If you can run an app as a user, hal has nothing to do with it.

I can run it as user. And I used to run it as root into user's environment. But now I can't:

[ted@myhost ~]$ su -
Password: 
[root@myhost ~]# firefox
Segmentation fault
[root@myhost ~]#

I have no idea where I may find something about it. Googling didn't help.

Second link is not my situation.:P
I guessed it's something happens with my GTK. So I run following:

[root@myhost ~]# systemsettings
systemsettings(3179): Communication problem with  "systemsettings" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.ServiceUnknown" : " "The name org.kde.systemsettings was not provided by any .service files" "

And when I run something based on QT & KDE I see the same as Firefox:

[root@myhost ~]# okular
Segmentation fault

I'm confused.:|

Nothing really helpful, but I'll post it anyway:

Maybe you should try updating / reinstalling KDE/Qt? If the problem doesn't go away, please file a bug report.

post your DAEMONS list from rc.conf. i guess you don't have the needed daemons running such as dbus

ps. why the hell do you want to run apps as root. man adduser

Sometimes I need to works with root's files by special apps.

Firefox??
Maybe sth is wrong w/ your permissions? In general, root and GUI don't mix.

wonder · 2010-05-20 19:48:58

i suggest to use kdm as login manager or if you prefer .xinitrc add exec ck-launch-session wm

Root doesn't have troubles with permissions.;)
I do know about risk using root's account.

I use kdm.
P.S. I added dbus to daemons list, but it doesn't help.

DAEMONS=(dbus syslog-ng network netfs crond hal alsa httpd mysqld vsftpd)

Root doesn't have troubles with permissions.

Neither does your user, if you keep things like they are supposed to... AFAIK if you randomly run "user" programs as root, this can mess things up. Also, what profile is firefox using under root? Hopefully a different one than normal, or you'll end up with very weird permissions.
