xterm

wogga · 05-31-2004, 05:49 PM

i tried to get xterm to work
i got the following message instead

[root@localhost tigger]# xterm
Xlib: connection to "0.0" refused by server
Xlib: No protocol specified

Warning: This program is an suid-root program or is being run by the root user. The full text os the error or warning messafe cannot be safely formatted in this environment. You may get a more descriptive message by rinning the programas a non-root user or by removing the suid bit on the executable.
xterm Xt error:Can't open display: %s

how can i also go back to normal user mode, at the moment i kill the terminal and open a new terminal

also previously i could copy paste text on the terminal, not now, why is that?

ah
i tried xterm when i am in normal mode, and it allows me to do it.
soon as i go into su mode, it gives me this error this time

and this time around, i can copy it
[root@localhost tigger]# xterm

When you do that (run xterm) are you in a tty or in an xwindows enviornment? A tty is black with just you and a blinking line. An x env is alll graphical.

What it looks like you aro doing is trying to run xterm from a TTY and you either have an X open already or you dont. how are you running this? Sometimes also is you

Are in a terminal an X and su - then try atd run a command that would launch a window you will get an error like that. For example (this in in an X term)

Code:

<tim>[~]<06:33 PM>:su -
Password: 
<root>[~]<06:33 PM>:aterm
Xlib: connection to ":0.0" refused by server
Xlib: Invalid MIT-MAGIC-COOKIE-1 key
aterm: can't open display :0

Thats what happens when you run an x application as su'd into root

i think i am in an xwindows environment, since the screen is white and there is no blinking line. but it does not look all graphical to me.

how can i find out for sure what mode i am in?
the code that you provided, are you trying to go from tty to an xterm?

i also tried to run startx and i got the following message
Fatal server error:
Server is already active for display 0
If this server is no longer running, remove /tmp/.X0-lock
and start again.

Hi Wogga,

What linux distribution do you use? (mandrake, fedora, slackware or what?)
The message you've got is from a console terminal.
In order to start xterm it is mandatory to run X first. This is normaly done with startx command from console.

Note: Mandrake, by default, will not allow you to get X if root :-(
Pls don't ask me why, I'm just a newbie slackware user ;-)

There are 6 virtual terminals where you can login as different users. One can switch between these terminals from console by pressing Alt-F1, Alt-F2 ... and so on till Alt-F6.
By pressing Alt-F7 you get the first X window display (if one is already active!), Alt-F8 the second.
If you are within a windows session, you can switch back to console by pressing Ctrl-Alt-F1, or 2,3...

Now, you first login on tty1, virtual terminal 1, and get user@localhost tigger. Press startx and you're on x.

I presume that your system boots directly to X.
Switch to the terminal no.2 (Ctrl-Alt-F2), login as root and type:

Code:

startx -- :2

type exactly as above, with blank space before and after --
You'll be on the second X session. Switch back to the first one by pressing Ctrl-Alt-F7 and again back with Ctrl-Alt-F8

Next: please read some linux docs and tutorials... :-)

Good luck!

I am using redhat 9.0
please advise me on a good tutorial
