General :: Cannot Remote Display To (ubuntu 9.04) Box?
Mar 12, 2010
I am struggling to figure out why I cannot display GUI applications from one of the Sun Solaris 10 servers (named espresso) on the network over to my local Linux workstation (beluga). Seems to work perfectly fine when I use my other Solaris 8 (stoli) box for display.Here is what I do, the part that works fine:
stoli: xhost+
stoli: rlogin espresso
espresso: setenv DISPLAY stoli:0.0
espresso: oclock
Now trying the same thing over to linux box, beluga, and it fails with message "Error: Can't open display: beluga:0.0":
beluga: xhost+
beluga: rlogin espresso
espresso: setenv DISPLAY beluga:0.0

I am connecting to remote Linux PCs via ssh, to update software and do other tasks. I want to send a notification to the remote PCs screen (eg, "Do not run program X, it is being updated now"), so the users do know what is happening.
Is there a reverse way for ssh -X host so I can connect to a remote Linux machine and run notify-send and it appears on the other display?

I hope this is not a totally ridiculous question. I use putty often to remotely connect to my laptop at home. I recently learned about the Linux framebuffer, and was curious if there was a tool like putty that would let me remotely connect to my laptop but use the /dev/fb0 device for forwarding graphics. Sort of like a vnc or X11 forwarding, but instead of using X, gdm, kdm etc. we use the framebuffer.

In the past, when I open a gvim session on a remote machine, the title bar of gvim would show the machine name in brackets. I am not sure if this was done by the remote gvim itself, or the local window manager. In the past I have used gnome2, although I am currently using unity (and finding it rather frustrating). Is there some setting I can change to always force remote windows to display the source machine?

I have SSH -X working fine, displaying stuff that's running on the remote machine on my local machine. But how do I display on the remote machine? I did this many years ago on unix and seem to recall that this was either default or a simple case of setting DISPLAY....

Hostname: Borg
OS: Lucid Lynx
Kernel: 2.6.32-24
Problem:
1. borg > xhost +
2. borg > ssh <anyuser>@<anyhost>
3. anyhost > export DISPLAY:<borg's IP>:0.0
4. xclock
NOTHING HAPPENS!!!! Any ideas? Here is what I have tried thus far.
Efforts:
1. gdmsetup - looked for security tab, doesn't exist
2. installed gdm2setup - still not there
3. looked for gdm.conf - not there
4. when doing ps -ef|grep X - there is a -nolisten tcp "could this be culprit" hmm not sure
5. modified /etc/ssh/ssh_config to Forward X

I'm having trouble displaying Xwindows programs on a remote machine. If I run "ssh -X newmachine" and I login and then run a program like xclock, I get the error message:
Error: Can't open display: localhost:10.0
If I run the same command to an anothermachine which is running Ubuntu 8.04 it works fine and xclock displays on my localmachine. If I run the command "echo $DISPLAY" on newmachine, I see:
localhost:10.0
Also, I have checked and xauth is installed on newmachine. What setting I have to change on Ubuntu 10.04 to allow remote display of Xwindows programs?

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:
xterm Xt error: cannot open display a.b.c.d:0.0

my local box is centos 5.5 running gnome.
I have a eucalyptus instance (vm) running an older version of centos (5.3?). As a vm it has no graphical display. I'd like to run a graphical app there so that it displays back on my local machine.
Used xhost locally and it shows the remote IP (eucalyptus instance) as enabled. On the remote side (eucalyptus instance) I set DISPLAY with:
export DISPLAY xx.xx.xx.xx:0.0
where xx.xx.xx.xx is my local ip address. Oh, I did install X in the vm instance (yum groupinstall "X Window System"). X is installed but not running there (does the point of origin of the x app need to have X running as well - and what does this mean in a vm which is a non-graphicla environment?).
Anyway, I try to run (from remote to local) xclock and get the typical
Error: Can't open display.

This is a strange problem, 2 Fedora 11 machines, both Dell's. On machine A, remote desktop is okay. On Machine B, remote desktop display is corrupt/unusable.
However, prior to upgrading to Fedora 11, both machines had Fedora 10, and, remote desktop on Machine A was corrupt and Machine B was okay.
Any idea what happened? Why did the upgrade fix one and break the other? Both machines where upgraded with Pre-upgrade. The two machines are in to separate locations, un-related to each other.

I'm running nxfree to log into my remote xubuntu PC from my local xubuntu laptop since the X protocol was broken.Has been working fine. Recently upgraded from Lucid 32bit to Maverick 64bit Xubuntu.Now when I run nxclient in fullscreen mode, if I minimize the window (or just log out) my local display does not return.I'm left with just the background colour. The windows are still there but not visible. For example I can:* randomly right-click and a menu pertaining to the invisible window appears;* press alt-tab and cycle through the windows but activating one does not display it (it remains invisible);* press ALT-F and bring up the current active (but invisible) application file menu;Basically I press ALT-F and ALT-TAB and close everything and then log out and log back in to restore the windows/panels.

I'm working on getting my myth box hooked up to my Sony flat panel display.Originally the nvidia drivers could not read the EID, so defaulted to only 640x480 over my HDMI-DVI connection.I manually updated xorg.conf with a mode for the resolution I know the thing can handle. Suddenly there are several resolutions avaialble in nvidia-settings and it seems to be communicating with the TV, as it is now listed as a Sony FP display rather than a CRT.I'm able to change the resolution now as expected.my problem, however, lies with the TV itself. I can't seem to get it to actually display the output. I'm able to remote desktop into the box and can see Gnome logged in and everything.However nothing on the TV itself.How do I troubleshoot this? Am I missing something obvious?

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
[code]....

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.

Canon cameras used to come with a piece of software called remote capture for Windows and MacOS.
You plug in the camera via USB, and then the camera display is on your monitor. From there you can do everything your camera does, like taking pictures of video. Does anyone know if there is linux equivalent software that can do this?
I have found this software, but new cameras aren't supported.

I maintain plain vanilla Ubuntu 10.04 systems for several friends. Each machine has only one user, the owner. I use Remote Desktop to instruct and to perform maintenance. Here's my problem:After updating the system, if the kernel has changed, a restart is needed. If I do a restart, I then have to phone the owner to insert his login credentials in the gdm login screen, before I can do anything else via Remote Desktop on that machine.There ought to be a simple way I can avoid the phone call and login myself.
I'd strongly prefer not to use any software that is not included in a plain vanilla Ubuntu 10.04 installation. And I don't want to weaken system security beyond what it is now.Is there a solution? Or, what is the simplest solution?

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.

We're using both SuSe and RHEL servers. Our servers are running behind firewall device and remote root login is disabled in SSH.
We're using NAT.
Remote client connections including failed logins are logged into the /var/log/messages but what is logged are gateway ip of our LAN - the LAN IP of Firewall device.
How can I logged the external or public IP of the remote client?

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.

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?

I have a machine running Ubuntu 10.04. I have a VPS (virtual private server) also running Ubuntu Linux. The VPS has a dedicated IP.
I want to have a setup, so that the directories on the VPS are accessible on my HOME PC like a mounted drive.
That is I should be able to do things like edit files on the VPS and copy/move files from/to my home PC to the VPS, as if the VPS was mounted on my box.

I'm using ubuntu (and compiz, though I'm not sure it's relevant) and I've been wondering something : how to display the desktop, as you would in windows using windows key+D ? In system-> preferences-> keyboard shortcuts there's an action called "hide all normal windows and set focus to the desktop". What does "normal windows" mean ?
When I press this shortcut (which seems to have the same effect as if you press the bottom left corner), the desktop is displayed, but there are some small squares in the corners that seem to be pieces of windows. What are these exactly, and if they're not useful, how can I make them disappear? Plus, if I press this shortcut twice, all windows disappear from the bottom panel (I don't know the proper name).
