Fedora Installation :: Mini-wm:1462 - Gtk-WARNING **: Cannot Open Display: :1

Jan 26, 2009

I'm trying to install Fedora10 on my new desktop. It has Windows 7 beta on it and Vista. It starts up fine and I select install. For some reason my wired usb keyboard will not respond unless I press the caps lock button while it loads the begging. (I don't know if another button will work, ive only used the caps button since i can see the light come on) once it loads i skip the disk check and anaconda runs, i get the warning (mini-wm:1462): Gtk-WARNING **: cannot open display: :1 .

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:


gnomesu -c "gnome-open '$uri'"

When I try using it, it just fails. Typing out the command in the terminal gives this (tested on a text file):


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....

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


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.

Jan 23, 2011

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:


# sudo gedit /usr/bin/deadbeef

..but every time I try, no matter the file, I get this error message:

I already know: I can circumvent this by going:


# xhost +local:root
# sudo su
# export DISPLAY=:0.0

I created a new virtual machine on my ESXi 4.1 host and had planned to install Centos 5.6 as the guest OS. The two ISOs required for the installation were stored on my local disk.

I powered on the VM, loaded the iso and managed to get the first installation screen until the test CD media screen. However after that, I was greeted with the following error message:

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 ?

Ubuntu Multimedia :: Videos Won't Display Properly In Netbook Remix (Lucid) On Dell Mini 10v?

Jun 8, 2010

I recently got a Canon Powershot SD780 IS. It takes HD video at 780p. It's great, except that the videos won't display properly in Ubuntu Netbook Remix (Lucid) on my Dell Mini 10v.I've tried using Gstreamer (Banshee), Xine (Totem-xine), and MPlayer (GNOME MPlayer). These all should have worked, which makes me think something may be wrong either with the files themselves or my computer. Anyone have any idea what's going on here?FYI, when I pull up the Properties dialogue for one of the videos and look in the Audio/Video tab, it says:

Dimensions: 1280 x 720
Codec: H.264 / AVC

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.

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.
<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.
