xhost +: unable to display

[Former Member]

Dear Linux and SAP Expert:

I am facing a problem, I want to install Oracle 9i on SUSE Linux, I need to use ora<sid> to install it, but when I use xhost +, i am prompted "xhost +: unable to display"

I have already set the followings:

setenv DISPLAY <my hostname>:0.0

xclock is also unable to display.

What can I do???How can I solve this problem?

Really really thanks for your all reply

Hi Glay,

Are you running "xhost +" with the root? You can't execute this with no-root user...

After doing it, su to orasid, export Display, and so on.

Hi Hisashi Glay,

You can try the following senario also if you are taking VNC over windows machine.

Install the vnc server package i.e vnc-server-x.x.x. and download the vnc client for windows i.e. UltraVNC Win32 Viewer 1.0.1.

After the above activity do the following configuration at server end.

run the command as a root or ora<SID>. Whose graphical login you required.

In our senarion we use ora<SID>.

run the command

vncserver

vncpasswd #This is to set the password for that vnc login

after run the vncserver change the following setting in xstartup file

cat ~/.vnc/xstartup

#!/bin/sh

1. Uncomment the following two lines for normal desktop:

2. unset SESSION_MANAGER

3. exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid grey

vncconfig -iconic &

xterm -geometry 80x241010 -ls -title "$VNCDESKTOP Desktop" &

twm &

**************************

chage the below line as follows.

unset SESSION_MANAGER

exec /etc/X11/xinit/xinitrc

#[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup

Afte this changes kill the vncserver once

vncserver -kill :1

than start the vnc server again.

vncserver

Everything is done now use the gui of that server from windows client machine

hostname:1 or IP Address:1

Hopefully this will resolve your problem

Hi Hisashi,

i recommend you to use X Forwarding through SSH to your local linux.

Try: yourpc:# ssh -X ora<sid>@hostname.com

The X Protocoll will be tunneled through the ssh Session, which is more save.
