Ubuntu :: 10.04 Laptop Can't Display Remote Xclock
Jul 27, 2010
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 recently dist-upgraded from Debian 5 to 6 (squeeze). Since then, the xclock I run from my window manager's start script isn't displaying correctly (it displays only a "0"). The thing is, if I run the same command in my start script in my terminal, it works just fine, as it has always done...
I use this rather "old" X applications because I like my programs simple/not buggy/fast, and it's resulting a rather annoying problem (being that apparently nobody else has it...).
All other programs in my start script (gnome-terminal, emacs, xmodmap, etc) are working with no problems whatsoever.
My window manager: sawfish
Command to run xclock in my start script:
Code:
xclock -digital -brief -geometry -0+0

I use kubuntu (8.04) which does not have a root account.
[sudo] password for ts:
However, starting xclock or gvim on root shell on konsole has the "Can't open display" error appears.
Error: Can't open display: localhost:0.0
Press ENTER or type command to continue

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....

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 attempted to install ubuntu 10.10 (64x) on to my Dell Inspiron M5010. it booted to cd, and got to the main menu. i clicked install ubuntu, and it thought for a little while, then turned to a black screen and it had a cursor in the top left that blinked. it didnt do anything for a while. wouldn't let me type or anything.
my brother said it might have been the cd, so i made another one. same thing happened. i assumed ubuntu 10.10 (64x) didnt like my computer, and i gave up. until, i attempted to install an earlier version of ubuntu. I managed to get ubuntu 9.04 (64x) installed on to my Dell Inspiron M5010 with no problems. now here is where the problem lies...
i went to upgrade ubuntu 9.04 to the next avail (ubuntu 9.10) and the updates went smoothly. but when the upgrade was finished and the computer restarted, after booting the computer wouldnt show any display. but i could tell ubuntu was okay because even though i couldnt see, i logged onto my user name. so ubuntu works, it just doesnt have a display.
so i reinstalled 9.04 (64x) that way i would be able to get some insight on this situation, and maybe make some changes before i upgrade again. because ultimately i want to have Ubuntu 10.10 upgraded on here.

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

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?

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.

I have a busted laptop, case that is. The internals are great. So I stripped the screen and built a large box. I used a cnc router to build a lid that would flush mount the screen, and have a lip of wood left to cover the metal edges of the screen.
Ok, what happened is that the measure twice cut once rule or one of its variants went into effect, and I put the hinge on the wrong side of the box. Normally I would say just flip the screen around, but one edge is wider than the other, so that will not do. I want have the hinge towards the couch so that I can tilt it up and be able to easily see the screen.
So I need a way to invert the screen, and I can't seem to find a way to do it. The coffee table is an Emachines N-10, and my video driver is the Nvidea one, because karmic told me my onboard card is not quite up to the task of the other one.

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 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.

I have created the following script which runs very well when it is executed alone.This script is to be run by a third party application (Oracle clusterware).The script (when is run by the application) doesn't successfully execute the xclock command. It even doesn't return the $USER variable.Following is what I got:

I have tried to connect my GMA500 based Acer 751 to an external dsiplay via VGA connection. I couldn't get the right resolution on the external screen (1920/1080) so I disconnected it and rebooted. Now there is only an "unknown" screen in the display menu. I have rewritten the xorg conf file per instructions for enabling GMA500 but to no avail - conf file looks right but screen is "unknown", low resolution and 4:3 aspect ratio, instead of 16:9. How to restore to laptop monitor - I think I can take from there to enable the right resolution.

Got a problem with Ubuntu 9.10 and a Lenovo T400 with an ATI Radeon Mobility HD3400 and ATI drivers /ATI contol center. Whenever the laptop wakes up from power-saving mode, the screen goes black (with some jagged mulicolored lines).

I am running ubuntu 9.10, on a Lenovo laptop. Has been working perfectly until now. But now my screen is split into 6 very small screens which all work in synch. That is - I have 6 mouse pointers - it is really like having 6 very small screens. All software is still working. However - I need to go back to only one screen in full-size. Has anyone ever experienced this. Using Nvidia accelerated graphics driver.

I am looking for a way to switch quickly and easily between my Laptop Display and my External Monitor, in Windows I had it configured so that when I plugged my Monitor in it would switch to that and when I removed it it would switch back to Laptop Display. From what I have tried it looks like this isn't possible with Linux, but I would like to get to the stage when I can click an icon to switch (or 1 to go to External and 1 to go to Laptop) My Laptop has an ATI Mobility Radeon HD 4500 Series Graphics Card and I have so far noticed the following issues.
1. If I use the Gnome Monitors instead of ATI Catalist Control Centre it seams to cause some strange issues include confusing Linux on what the max screen res supported by my External Monitor is.
2. When I try and enable/Disable either Display or change Resolution, I am told that I have to reboot before the changes take affect.

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 want to change the default behavior of my display hotkey combo (Fn+F7). I can do this in KDE, but in Gnome, the gnome-settings-daemon cycles through the options. Problem is, the option I want is not there. I want the laptop display on the right and the external display on the left. I know how to use xrandr to change this or to use System > Preferences > Display, but I want to use my hotkey combo. I see two ways to do this. Find the configuration file that selects the options that are cycled and manually edit it, or disable this hotkey combo for the gnome-settings-daemon and use my own script in /etc/acpi/actions, etc/acpi/events for the hotkey combo. Currently the gnome-settings-daemon intercepts the hotkey combo, so I can't use my own script. Anyone know anything about this, or do I need to file a bug report?

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 an ubuntu fileserver and an ubuntu laptop both running 10.10.For some reason I can't connect to the server (file or remote terminal) from the laptop, even though I can access ssh through terminal on my mac and have been able to mount the filesystem on another computer running the ubuntu liveCD. I just get the error 'no route to host'.I've tried turning off the firewall on the laptop and re-installing ssh on both computers, but I don't have a clue what to do next!

Fresh installation of Fedora 14 x86-64 on Lenovo T510. I'm trying to setup graphical remote connection to this laptop via VNC. I installed vnc-server package and altered /etc/sysconfig/vncservers accordingly:
Code:
VNCSERVERS="2:awajda"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
I found Remote Desktop which opens vino-preferences and ticked the check boxes there. I started vnc-server and then I tried to connect to it from the same local host using vncviewer. I got no errors and the window with correct resolution came up. The problem is - that window is black and empty. I tried looking into Fedora docs but I haven't found anything useful there. I tried google and I found about 487693746874363 solutions and different ways of installing and configuring VNC server. I tried a few - none helped.
I wonder if there is a decent and consistent documentation about how to make remote desktop working in Fedora without having a real pain in the ass trying out those gazillion tweaks and tricks from various forums and blogs? After all Fedora 14 comes with that Remove Desktop thing available out of the box. Is it a real working thing or just a marketing Should I uninstall all the preinstalled VNC stuff and follow one of those painful instructions found on the internet from A to Z praying for it to eventually start working after all the magic is done and hours or days are wasted?

I have a new Dell Studio XPS laptop (I have used dell laptops for many many years running Fedora linux). And for the first time I want to setup the Infrared remote control in the laptop.
That is I like to set up a remote to start and stop movies and sound playback.
I installed LIRC and after reboot I see devices such as /dev/ircomm0 to /dev/ircom31 as well as /dev/irnet
So what next?
The LIRC website just goes on about using serial dongles, but nothing on setting up a laptop with a built-in IR sensor. It also talks about using irrecord, but that program complains about no /dev/lirc0 device.
I tried installing a "gnome-lirc-properties" (whcih also installed "lirc-remotes" package), but it fails with a verbose 'python traceback' that doesn't tell you what is wrong.
