OpenSUSE :: Gtk-WARNING **: Cannot Open Display: :0

May 29, 2011

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.

Ubuntu :: Gtk-WARNING **: Cannot Open Display: :0.0

Jan 13, 2010

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....

Ubuntu :: Gtk-warning - Cannot Open Display

Jan 30, 2011

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

The update manager checked some updates to install and after installing them, I had no graphic desktop any more. Only the command line.

I tried to recover it by starting the X again.

But did not worked

So I've tried to install the nVidia driver again. I looked at nVidia Linux drivers site for how to do it and Ubuntu documentation and when I tried to

Code:

I just could not use gedit. It cannot open display. I googled for three days but could not solve it. I found some similar answers here at LQ but none was similar to my situation or worked even when I tried.

I've been searching for a permanent solution for some time now, but the threads containing the same error message never seem to be about the same issue.I want to:I'm not trying anything fancy, all I want to do is open a write-protected file with gedit as root, like so:

Code:

Code:

I already know: I can circumvent this by going:

Debian :: Error: Cannot Open Display: 0 When Trying To Launch Firefox

Sep 8, 2010

So I just installed 32-bit Squeeze. I've done exactly two things since booting into the first install: pt-get install gtk+2.0, and ./firefox, so unless gtk did something, this might be an easily fixable problem with Debian itself. After installing gtk and trying to run firefox via command line, it tells me

Code: Error: cannot open display: :0 I googled a bit and couldn't come up with a solid solution, but the problem seems to be around other places. Any idea how to fix this?

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.

Ubuntu :: Display Driver Warning When Upgrading To 10.04 LTS?

Oct 16, 2010

planning to upgrade to the next LTS version i.e. 10.04. Have already applied all the updates and got the system up-to-date prior to upgrading. But when the upgrade starts I get the following message: Upgrading may reduce desktop effects and performance in games and other graphically intensive programs.This computer is currently using the AMD 'fglrx' graphics driver. No version of this driver is available that works with your hardware in Ubuntu 10.04 LTS.

Do you want to continue ?Obviously, I clicked on NO and got out.What gives ? How come an upgrade is supposed to DEGRADE performance ? What kind of upgrade is that ? Also what is the implication for me ? Will I have to happy with 8.04 forever ?The machine in question is a Toshiba Satellite A100. I use GIMP quite a bit on it, so problems with graphics intensive applications is kind of worrying.What am I supposed to do ?? Upgrade anyway or stick with 8.04 ?

General :: X11 Forwarding - Error: Can't Open Display: <ip Of Display>

Jun 28, 2011

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.

OpenSUSE :: Root Trying To Open Flashplayer In KDE Getting Cannot Open Display

Feb 18, 2011

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
