I wonder if I could get a hand from you guys, thanks a lot!

Hi,

when you take a look at the OUI output you see "Can't connect to X11 ...";
in other words the X Server is missing a display to output the oui screen.
This is probably becaus you are trying to install from a remote terminal
/ remote host. Simply go to the server console, open a terminal window like
xterm, change to the directory where runInstaller is located and try again.
If you are establishing a remote session with ssh do not forget the -X switch.

good luck

martin

I installed my Ubuntu Linux on Frank-PC, and what I did before are all on this PC locally.

up!!!!!!!!

Huh? Is it still not working? If you're doing this locally type "xhost +localhost" to allow all local connections to the X server and try again.

Thank u!
But I can do that using "root", but for the other users, it doesn't work!
I got lost!
It shows:

root@Frank-PC:~# xhost
access control enabled, only authorized clients can connect
INET:Frank-PC
root@Frank-PC:~# su - oracle
oracle@Frank-PC:~$ xhost
xhost: unable to open display ""
oracle@Frank-PC:~$ export DISPLAY=192.168.1.188:0.0
oracle@Frank-PC:~$ xhost
xhost: unable to open display "192.168.1.188:0.0"
