Make sure that your X server is running and that $DISPLAY is set correctly.




this also what is this?


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

Are you trying to start another session on another screen? Are you using ssh? Or are you having a problem with your video setup causing X to fail?

What are you looking at and what have you done so far. We don't have any context to work on to help you out.

X server is a server that let you run Gnome,KDE,or some other desktop environment,it enables you grafical user environment.I don't know what your problem is,because you haven't been specific,but you should try to delete that tmp file.

I think you probably missed file at /etc/conf. Try type this "startx". If it can't help you, boot with live cd and copy that file to your hard disk and paste it when you enter your linux. Or, as my experienced said, installed it again

Did you mean /etc/X11/xorg.conf?

I typed startx and this is what i got

xauth: creating new authority file /root/.serverauth.3040

xinit: Resource temporarily unavailable (errno 11): unable to connect to X server
xinit: No such process (errno 3): Server error.

copy /etc/X11/xorg.conf from another live cd and paste it into your flash disk. Then, boot from your linux and paste it
