Ubuntu Networking :: Set Display And Xhost: Unable To Open Display "XXX.XXX.X.XXX:0.0"
Jul 20, 2011
I have configured an instance in AWS EC2. I am trying to set the display back so I can run x apps. I login using ssh -xy -i...
export DISPLAY=XXX.XXX.X.XXX:0.0
echo $DISPLAY to verify
xhost +
xhost: unable to open display "XXX.XXX.X.XXX:0.0"
I have commented out nolisten tcp as suggested HERE I have modified /etc/gdm/custom.conf as suggested HERE Actually, the last suggested modifying /etc/gdm/gdm.conf, but that file didn't exist, so I added the line: DisallowTCP=false to /etc/gdm/custom.conf I rebooted, and still I get: xhost: unable to open display "XXX.XXX.X.XXX:0.0"

We rebooted the server an got the following error:
Quote:
RHEL xhost unable to open display ""
Can't login or do anything at the monitor or kb. How ever I can ssh to the server, not sure where to start looking. I have two servers that are the same and checked the xorg.conf on both servers and they looked the same.

I have the following scenario that doesn't seem to work normally. I have a windows 7 pc from which I am using putty to connect to my other linux servers (all running redhat 5 and 6). So here is the scenario that works and one that does not work. And I'm trying to figure out the one that does not work. Scenario that works:
From windows 7 (putty) I ssh into Linux_Server_1.
echo $DISPLAY
localhost:10.0
I run xclock and I see it pop up on my windows 7 pc. I am using xming on windows 7 to help me populate the display from linux to windows. One that does not work:
From windows 7 (putty) I ssh into Linux_Server_1. Then from Linux_Server_1 I ssh into Linux_Server_2.
echo $DISPLAY
<no output>
I try to setup $DISPLAY with localhost:10.0 or 0.0 or even my windows 7 pc ip address:0.0 ....etc Then when I try to run xclock I doesn't work.
I get these error messages: Error: Can't open display: <ip of display>
Also as a side note all our Linux servers are sitting on one subnet. My pc is sitting on another subnet. I use vpn to connect to the subnet where the servers sit from my pc.

I'm SSH'ed in to my Ubuntu 11.04 machine and trying to take a screen shot of a virtual display where I'm running (hopefully) Firefox. I get the error
Code:

I know that I have displayed the right display variable because in an earlier script that runs at system bootup I have

I'm experimenting with old linux Distributions again, and while trying tostart an x server, I get the following error message:X: unable to open display ''That makes me think that the config file is incomplete, but I would have no idea how to make it. If there is an auto configuration utility that I do not know about for X, it would be great to hear about. Here are some other specifications that might help:*Host: VMWare Workstation on Windows XP Home*Distribution: Debian 2.2 (potato) (Yes, I know it's old.)*Connection: Local. I've heard of people having difficulties like this on remote connections, but I am on the physical computer

I am unable to open any new windows then and lots of programs crash.

i recently moved from Ubuntu to Debian(squeeze).. i am very pleased with squeeze except for this bug..I have this python script i wrote to change my wallpaper (through Gconf), the script would be called by cron from time to time.The problem i am facing in Debian is that this script stopped working.I am exporting the $DISPLAY=:0 in Cron, (this is how it worked in Ubuntu)..the cron job i used is below:
-----------
* * * * * export DISPLAY=:0 && /path/to/my/script.py
--------
so the above was not running...I redirected the output and this is what i got as error:
-------------
Failed to contact configuration server; the most common cause is a missing or misconfigured D-Bus session bus daemon. See http://projects.gnome.org/gconf/ for information. (Details - 1: Failed to get connection to session: /usr/bin/dbus-launch terminated abnormally with the following error: Invalid MIT-MAGIC-COOKIE-1 keyAutolaunch error: X11 initialization failed.)

/opt/openoffice4/program/soffice.bin X11 error: Can't open display:
Set DISPLAY environment variable, use -display option
or check permissions of your X-Server

Open Office works fine when I run the command "startx" in the Konsole but so far I haven't been able to configure it.

We have a digital signage appliance built on SUSE 11.3 with a LAMP server that uses the flashplayer application to play a .swf file from localhost. It is a AOpen GP7A mini pc that has the nVidia drivers loaded. We have lots of customers that have been running the exact same system for over 6 months (we image the drive for each sale).
For some reason, my last customer is seeing the following problem shown below, and this linux configuration is way over my head. Everything else is working (local LAMP server is working, communicating with our production servers to get information works, etc). I have verified that it is screen 0 that is running (at least it shows with Ctrl-Alt-F7). I thought that it may have occurred because of updating the software with zypper up. I had the customer rebuild from the image being careful not to upgrade the software. The result was the same. The pc is a newer version compared to my bench pc, but there are multiple other customers running that same version just fine. So I am not sure if it is
The command is issued by a php script that is run in a root cron job. As I said, it works great on all other customer pc's including my bench system. I also tried to execute the command on a ssh terminal as the root user with the same result. I also upgraded my bench pc and it still worked properly.
The command being executed is sudo env DISPLAY=:0 XAUTHORITY=/home/svision/.Xauthority flashplayer http://localhost/flash/sign.swf &
the result (when run in terminal) is: No protocol specified (flashplayer:15077): Gtk-WARNING **: cannot open display: :0

Hi I am new to ubuntu and am having major problems setting my displays up. my setup is a hd TV to the Left of my pc monitor, i have managed to configure catalyst to let me have a main display with the second display being an extension of the first, the problem is i cannot seem to swap my primary display, at the minute my HDTV has all the taskbars and everything on it while my pc monitor is just a blank background, i would like it so i could start a film playing for my children, then drag it across to the HDTV while i can still use my pc in the background.

I have a fresh install of OpenSUSE 11.4 64bit and I have installed the AMD Display drivers for my Radeon HD 5970. Everything seems to be working quite well. I have a multiple monitor setup (1280x1024 monitor and a 1920x1080 monitor).
I have my primary display set to 1920x1080, however when I try to enable the second display, I get a CRTC error that the display is over the maximum (1920x1920). If I enable both monitors at lower resolutions, there is no problem.
I have done a fair bit of reading and have been unable to determine where this maximum is set, or how to change it. I'd like to be able to run both monitors at their native resolutions.

When i ssh to server using -X, i always confuse about which display number i should export. It seems to me sometimes the display number has been used by something, so what i can do is only
export DISPLAY=localhost:0 && xclock
export DISPLAY=localhost:1 && xclock
export DISPLAY=localhost:2 && xclock

I did not have any /etc/X11/xorg.conf, so I read on these forums that system-config-display would create one for me. I ran system-config-display and it created an xorg.conf. But now my display is all messed up!! So, I deleted the xorg.conf and nothing changed. Why on earth would the display still be messed up if I deleted the file that was causing it?? Does system-config-display change somethign else?

When I become root and try to run gedit, I get the error:
No protocol specified
(gedit:219: Gtk-WARNING **: cannot open display: :0.0
This does not happen from my user profile....xhost + actually solves the issue....so I guess I just need to add the host root to the list of hosts allowed to access the x server...
I try xhost +root......but that does not work....

I was running Ubuntu 10.10 Maverick with no big problems till last 3 days ago.

For example, the gparted application menu item doesn't work; using it means that there is almost no filesystem support. The only way to get it to work is to open a terminal, run 'su -', and then open it from there.As another example, I tried creating a nautilus script to open files as root with a command like this:
Code:
for uri in $NAUTILUS_SCRIPT_SELECTED_URIS; do
gnomesu -c "gnome-open '$uri'"
done
When I try using it, it just fails. Typing out the command in the terminal gives this (tested on a text file):
Code:
No protocol specified
(gedit:13672): Gtk-WARNING **: cannot open display: :0
I'm pretty sure the problem is that it's granting privileges, but not using the full root environment, or something along those lines.
