Help: Startx is useless in my box

Hi,

I use SuSE 10.2 in my box. While I'm using "startx" to convert 3 run-level
to 5 in root user, it displays

hostname:Unknown host
xauth:creating new authority file/root/.serverauth.5758

Fatal server error:
Server is already active for display 0
If this server is no longer running,remove /tmp/.X0_lock
and start again

Please consult the The X.Org Fondating support
at http://wiki.X.Org
for help

How to solve this problem?

Thank you very much~

Regards,

Amy Lee

When you want to change runlevel you should use init. If you just want
to start X using startx should do.

Lets try it:

- are you sure that you are in runlevel 3 when trying "startx"?
- what X does SuSE install? Xorg or XFree?
- Maybe you are in fact in runlevel 5 and your X Server is running?
This would perfectly explain the error.
BTW: i found an (old) web page claiming that runlevel 3 in SuSE
would be with X started?

To verify this, run on the console or terminal as root:

"runlevel" -> will give you the current runlevel
"ps -ef | grep X" -> will show if X is already running, for Xorg there
will be a line containing something like "/usr/bin/Xorg :0"
What does the file /tmp/.X0_lock contain?
