Fedora :: Coin Error In Glxglue_init(): Couldn't Open NULL Display
Jan 23, 2010
I wrote a simple code using Open Inventor(OpenGL) classes to print a Sphere in a .png file.I tested it on Windows and it worked well.But when I run it on Fedora 10, I got the following error with no output .png file:
Coin error in glxglue_init(): Couldn't open NULL display. Coin warning in SoOffscreenRenderer::renderFromBase(): Could not set up an offscreen OpenGL context.
create a VM here with virsh. I've managed to create the XML file and got it to work properly, however running it is the problem. These are the errors I get error: Failed to start domain Cent-OS, internal error process exited while connecting to monitor: open /dev/kvm: No such file or directory ,Could not initialize KVM, will disable KVM support qemu: could not open disk image /media/55D123D9E79ABF54/VM/Cent-OS-5.5.img: Permission denied
I have just finished an install of Cent 5.5. I loaded up a trunk for a software application I want to compile on cent, but I cannot read the .cpp files. The issue seems to be with the file extension. If I change the extension to .txt, they open just fine. My .FOR, .FPP, and .DAT files display fine, but the .cpp and .h give me an error, "Couldn't display...". What is the problem here that won't let me open these files in gedit?
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.
this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.

I am having issues with 3d I am trying to start up a game called auteria but it displays this error "Could not find a compatible opengl display resolution. Please check your driver configuration. (Error: Couldn't find a matching GLX visual)" I am on ubuntu 10.10 could anybody give me a solution on how to fix this issue?
I've been having issues with the omega.cert on Pidgin and tried to upgrade to 2.7.7 today. I clicked on the link from the Pidgin site to download the ppa package "pidgin-ppa_0.0.3_all.deb" and tried to open with GDebi Package Installer but it tells me it couldn't be opened because an unknown error occurred.
I could locate the reason for this as far as it has something to do with my icon theme. I use Mac4Lin Icon theme, which is the one causing those crashes. With another one it works fine.So the problem is now, that I don't want to change the theme, I want to find out what's the matter and fix it. Because the error message says something about spinner I tried to erase the folders "actions" and "spinner" first, but with no effect, so I restored them. how to find out exactly what's the issue or which icon causes the crash?

I have a Dell xps with a dual core, 8 gigs ram, a primary hard drive with vista on it, and a secondary with linux in its future. It starts loading vmlinuz but ends up with the kernel panic before anything else. I am able to install earlier cores (5-8) and vista recognizes the ram just fine.
I downloaded truecrypt Linux version, giving me a file named truecrypt-6.3a-ubuntu-x86.tar.gz. I assume that's the archive. Double clicking on that produced file truecrypt-6.3a-setup-ubuntu-x86. I assume that's the executable. When I try to run that, I get a "could not display ... unknown filetype" error. Could someone tell me what I'm doing wrong? I plan to run truecrypt under the easycrypt GUI.
Having an odd boot message with Ubuntu 10.04. I've had it since I first installed Ubuntu a few months back and I am getting tired of it slowing down my boot up time.No luck on the Ubuntu forums or bug reports; no one seems to know what to do.uote:udevd-work  open /dev/null failed no such file or directory
I always had the x86 installed on my laptop, but I figured for fedora 12 I would install the i386 version so I would only have to burn 1 disc (desktop needs i386). But the first few days, I couldn't open the firewall from the menu because it always crashed. From terminal no problem. This was with a couple of these standard gnome apps. With the 'autmatic bug reporting tool' I can now see how many times each program crashes. Samba still crashes every time I try to open it, python crashed, firefox loves to crash these days (with a flash open), amsn crashed a couple of times (empathy and telepathy-butterfly packages).Ofcourse I update my system every few days, so I have the latest updates of each package.
I have a server running Red Hat Enterprise Linux ES (188.8.131.52.ELsmp). When it starts up I get the following error: Uncompressing Linux... Ok, booting the kernel. Red Hat nash version 184.108.40.206 starting WARNING: can't access (null) exec of init ((null)) failed!!!: 14 unmount /initrd/dev failed: 2 Kernel panic - not syncing: Attempted to kill init!
After that I got no response from the OS. I have the installation CD, so I tried to start the rescue mode, while going through the steps I received an error stating that mounting to /mnt/sysimage failed and that if I want to I can access a shell. I really don't know what to do from here
I know GEdit has a bug which prevents it from opening a file with null () characters in it. This is a huge inconvenience for me because I frequently have to open big log files with only a couple rogue 's in them.
Sometimes I just run a quick tr -d '' < file.log > file.log.correct and open the correct file. This is a big nuisance. I would like to have maybe an external tool in GEdit that would execute the above command. I tried writing an external tool action (GEdit plugin) using just:
#!/bin/bash tr -d ''
Input is "current document", output action is "replace current document". But this isn't working. When I open the file, GEdit shows the familiar red warning; activating the external tool with the warning showing apparently has no effect (I think the script is being called but its input/output are not set).
I have an HP OfficeJet 5610v installed on my system, and cups can print the test page. I can also get the test page to print via [URL] which appears to be printed under the anonymous user. Now if I attempt to print the test page via the printer control panel from windows, I get the following sets of error:

CUPS is showing that the "user" is my XP login name so I added that user to Linux and even added that account to the "lp" group and still get the above errors.
I was trying to remotely log in to my desktop which uses 11.3 from my laptop via ssh. For some reason I get an empty field for the command echo $DISPLAY. and as a result an xclock command results in error: can't open display. I tried to set it to localhost:10.0 and I get: Error: Can't open display: localhost:10.0
I've tried :0.0 and I get: Invalid MIT-MAGIC-COOKIE-1 keyError: Can't open display: :0.0 ssh used to work about a week ago before I performed various security updates. I was wondering what' the solution to this. I checked the /etc/ssh/sshd_config file and ssh_config file both have X11 forwarding on. Can anyone with more experience out there give me any ideas?
When I attempt to use Putty for xterm (to run DBCA for Oracle) I check x11 and put my IP Address in the Display field of putty. However, when I then try to execute ./dbca I receive the following:
Xlib: connection to "localhost:10.0" refused by server Xlib: PuTTY X11 proxy: wrong authentication protocol attempted Error: Can't open display: localhost:10.0
I notice the following when logging in to the server as well.
Last login: Fri Mar 19 13:51:19 2010 from 10.47.48.33 /usr/X11R6/bin/xauth: error in locking authority file /home/oracle/.Xauthority. These are the same steps I take successfully on all the servers. The above file exists on the servers I can initiate the GUI, but not on <server1>.
I tried to connect to remote server ,which is installed Centos 5.4 x86, through Xmanager on windows 7, and got this error.
/usr/bin/xterm Xt error: Can't open display: %s
At the remote server, I turned on firewall and after this I got the above-mentioned error message. I do this accrding to instruction on remote server.
2. Firewall (TCP/UDP Ports) Configuration Open UDP port 177 from the PC to the remote host direction. Open incoming TCP ports 6000~6010 from the remote host to your PC. After adding these ports "/etc/sysconfig/iptable" as the enoder mentioned, /etc/init.d/iptables restart
3. Reboot the remote host and start Xmanager <- I could not restart remote server.
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?
For awhile I have had this issue with the command line and every time I try to complete any command that requires GTK graphics, It always returns the error "Error: cannot open display: 0:" The "EXPORT display" command that I normally use to fix this issue is not working. The only issue that I can think might be the cause for this could be my upgrade to natty (which was in fact a clean installation), or when I edited plymouth so that the startup and shutdown animations would match my laptop's native resolution (by the way I would also appreciate it if I could do the same with the startup animation, only the shutdown really works). If anybody know how I could resolve this issue I would greatly appreciate it. Oh and for specifics on my machine, I am using an ASUS N82 with an NVIDIA GEFORCE GT335M graphics card, running Ubuntu 11.04.
I am running hummingbird exceed on Workstation with an ip address of a.b.c.d, and connecting to a sun machine with IP address x.y.z.w running Solaris with XDMCP. From the sun machine, we commonly telnet to other sun and linux machines and run X applications.
We have just installed ubuntu 10.04, and I can telnet into that machine no problem.
However, running xterm on the ubuntu machine fails:
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 also had ever tried all methods they mentioned, but my problem is still there. I am using a MAC OS X 10.6 ssh a remote redhat server. I hope to see X of redhat on my own MAC. Below is what I've done: 'MAC_ip' stands for my mac; 'redhat_ip' stands for redhat server.
1) ssh to redhat server 2) change to root 3) type command: DISPLAY=MAC_ip:0.0 4) type command: export 5) Back to MAC 6) change to root 7) type command: xhost +Redhat_ip 8) vim /etc/ssh_config, add X11Forwarding yes 9) Back to redhat, type: xclock
I got below message: Error: Can't open display: MAC_ip:0.0 I also tried some methods to login as others suggested:
