Oracle Installation Problem : X11 problem

Most probably you will see this line in your error " X11 window server using '192.168.1.2:0.0' as the value of the DISPLAY variable "


This clearly says that problem is related to X11 . . .




Steps :
---------
1) Try executing xeyes as root and check wheather it shows or not . . 
2) now login as your oracle account as ,

    su - oracle


3) Try executing xeyes again if error pops up something like this :


    Xlib: connection to ":0.0" refused by server
    Xlib: No protocol specified

    Error: Can't open display: :0.0

4) Go ahed by firing :  xterm and you will see TERMINAL OPENED 

5) thats it now you can fire xeyes from that terminal 

6) run your oracle installer as  ./runInstaller

Thats It !
