Debian Multimedia :: Invalid MIT-MAGIC-COOKIE-1 Keyxhost: Unable To Open Display ":0"
Aug 19, 2011
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.)
-------------

I am trying to ssh a remote system and redirect X with:
ssh -X remote.system.somewhere

I installed Open Office 4 on Debian 8 but when I run the program I get this error message.
root@localhost:/home/paul# openoffice4

/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
(See "man X" resp. "man xhost" for details)
Open Office works fine when I run the command "startx" in the Konsole but so far I haven't been able to configure it.

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

Well after messing with compiz Opacity I managed to make all panels and windows transparent. Only thing I see is desktop background and icons. Tried ctrl+although+f1 and running gconftool-2 --recursive-unset /apps/compiz
Then a reboot. Same issue. Next ran metacity --replace I get: Windows manager error: Unable to open X display

I'm looking for a program that will add cookies to my web browser (firefox or chrome, preferably). The application would ask me for the Cookie's:Name
Content
Domain
Path
Send For (type of connection)
Expiration Date
If no one knows of an application that does this, does anyone know what files i could manually edit in order to change a particular browser's cookie values?

This has to be the sixth time I am going to have to reinstall Ubuntu (Can't get enough of that Linux greatness) in the past 6 months. I just don't understand what exactly is wrong, I don't install anything extra (but the ubuntu restricted extras) yet updates that ask me to reboot will take me to a GRUB command line screen and trying to boot through the command line interface gives me an, "Invalid Magic Number", error.
There should be an official tool for when problems like this come up, so that users like me can easily move their files off their HDD before reinstalling. I didn't come here to rant but, does anyone know what may be causing this everytime, how it can be avoided maybe even how to deal with the Magic Number error and boot in (I wouldn't mind typing in the commands every time BTW)?
My system
Hp Compaq 6730s
2.0Ghz 575 Celeron
4GB RAM
Intel X4500MHD
Broadcom 802.11b/g

I've compiled and added a kernel in Gentoo before. It doesn't seem to go quite as smoothly in Kubuntu 9.10 These are the steps I followed: I unpacked the kernel in /usr/src and ran make && make modules_install succesfully. Then I copied the kernel in arch/x86/boot/bzImage to /boot/bzImage-2.6.32 This entry is the one given by Kubuntu:
Code:
menuentry "Ubuntu, Linux 2.6.31-14-generic" {
recordfail=1
if [ -n ${have_grubenv} ]; then save_env recordfail; fi
set quiet=1
[code]....
I just read the script that update grub uses. Changed the name of the kernel from xyz to vmlinuz-2.6.32-generic and it worked.

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"

i wanted to see the red hat side of things and do some virtualization with CentOS, so i am trying to dual boot ubuntu 10.04 LTS and CentOS 5.5. the machine is a laptop, toshiba A100 series. what I did was to create the following partitioning scheme via Ubuntu LiveCd
Code:
Device Boot Start End Blocks Id System
/dev/sda1 * 1 19457 156288290+ 5 Extended
/dev/sda5 1 2103 16892284+ 83 Linux
/dev/sda6 2104 9988 63336231 83 Linux
/dev/sda7 9995 12623 21117411 83 Linux
/dev/sda8 12624 18800 49616721 83 Linux
/dev/sda9 18801 19457 5277321 82 Linux swap / Solaris
created an extended partition and in there have made sda5 and sda6 as / and home for ubuntu and sda7 and sda8 as / and home for CentOS. and sda9 as swap. I installed ubuntu first and then installed CentOS with no bootloader. Run sudo update-grub through ubuntu and now i have both Ubuntu and CentOS available. But when i select CentOS, i have an error which reads "invalid magic number".
I have grub2 installed, haven't downgraded or done anything to it and the ubuntu install is fresh, one week since i updated to 10.04 from scratch. I have found much contradictory stuff on google, but not something that provides a definite solution and also this post but the second command provided in the solution is one i cannot understand very well and it doesn't seem to work. what I am doing wrong here and how to make this work. I would prefer to do things via Ubuntu since debian stuff is what i am comfortable with and i am installing CentOS to learn not to do work on it.

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

I tried the steps usually offered (modifying the grub.cfg file, replacing the wubildr files), it still wouldn't boot.
I booted in with the LiveCD to try to chroot into the environment and try running 'update-grub'. However, whenever I tried to chroot, it said it could not execute /bin/bash!
Trying to modify the grub commands manually (which originally gave the error: you need to load the kernal first), in the end said "invalid magic number"
There are some configuration things set in this installation I would like to not lose. Is it hopeless?

I want to get my PS3 Eyetoy working as a webcam on my Ubuntu box for use with Skype etc. When plugged in, the camera portion works fine and is recognised immediately. However, I am unable to get the microphone working. It appears to be recognised, but there isn't anything captured from it.
I have removed PulseAudio as it was interfering with my quest to get 5.1 working over HDMI passthrough in XBMC.
I did have it working briefly, but I must have changed something, and now I cannot get it to work for love, nor money!
This is what my system finds:
Code:
$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: CameraB409241 [USB Camera-B4.09.24.1], device 0: USB Audio [USB Audio]

Subdevice #0: subdevice #0
I have tried alsamixer -c 1, but that gives me the following error:
Code:

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

I installed Debian 5.03 Lenny successfully on my machine. I got this error during boot: ACPI : invalid PBLK length [5]. After that the Operating System boots properly and starts normally. What does this error statement mean? Is it safe to work with this installation despite this error?

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?

When I open an open office document from an NFS share it always opens as readonly. This was a problem I had on Arch linux and the fix was to change the locking options in the soffice script but I've tried that fix here and it doesn't work. I've seen a lot of discussions but they all go back to changing the locking options in soffice, has anyone got any alternative fixes or one that definitely works with locking?

We rebooted the server an got the following error:
Quote:

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.

Just switched to openesuse and kde enviroment few days ago, and now I'm snooping around etc.
Anyway I'm having this problem, I'm running a file server at home for my video, data, music and so on. I've used ubuntu untill now (server is also running ubuntu), and I've used vlc to watch the files directly from the server, I never had any problems with it until now (in ubuntu gnome). I navigated with nautilus to a location on the server double clicked and the video opend in my local vlc. Now I'm getting the tittle error, using opensuse 11.2 kde 4 and dolphin. Also I'm told to check the log...
While back I installed dolphin in my gnome on ubuntu, and i remember I got the same error when i tred to open the file on a server and tried to play it in vlc tru dolphin. So...Is this a known issue? Could this be related to dolphin/kde? Where is the vlc log file in opensuse 11.2? Where can I find some workarounds or something?
