Invalid MIT-MAGIC-COOKIE-1

[crankshaft]

Urghh;

Dunno what happened, just did a fresh install, and updated using YUM. Installed firefox using yum and re-booted.

Now I cannot login as Root , and error box says "Root logins not allowed".

If I switch to terminal mode and login as root and then run startx I get:

Fatal Server Error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock

connection to "0.0" refused by server
Invalid MIT-MAGIC-COOKIE-1
giving up
unable to connect to X server
no such process (errno 3): server Error.

I have tried renaming .X0-lock but it makes no difference !

Any ideas ??

Thanx

How did you "switch to terminal mode"? If you used Ctrl-Alt-Fn, the X server is still running on virtual terminal 7 and you can't start another X session (without some extra tricks). You shouldn't login as root anyway, use your normal username to login and use "su" or "sudo" when you must run system maintance commands.

Hi Mark;

Thanx, I am aware of the recommendation not to normally login as root, but I could do befor and can't now so I am curious to know why !

Thanx

maybe a security setting

you using gdm as a login a screen ?

You log in under your account
and can switch to root with sudo or su or su -
etc....

you log out of your user account and try to log in as root
and it barks at you

right ?

in gnome

Applicatons---> system settings---> login screen

Enter root passwd


Click the Security tab and see if allow root login with GDM is checked
uncheck the remote root login with GDM while you are there No sense in someone having root's password and playing with your PC with out your knowledge.

Can you log into X server using another User?

If you didn't make another user,
get into terminal
/sbin/useradd <name>
passwd <name>

OK, thanx for the help:

1) I can login as other users, I cannot login as Root
2) I am using KDE and not Gnome (Gnome is not installed)
3) Root login with GDM is checked in Login Screen

But here's something peculiar, I have installed KDE and have run switchdesk KDE, but the interface looks like GNOME. I could swear I installed GNOME but when I try and switch I get an error saying that GNOME is not installed !

I am going to re-install GNOME using YUM and try a switch desktop to GNOME.

Thanx
