ubuntu-desktop installed in server but getting error: no display specified

ravisingh1 · 09-07-2013, 09:19 PM

Hi
I got ubuntu-desktop installed on my remote server.
But still I am not able to open GUI.
Please have a look below for the error I get when trying to open
firefox and gparted.

Code:

ravbholua@ravi:~$ type firefox
firefox is hashed (/usr/bin/firefox)
ravbholua@ravi:~$ firefox

(process:7517): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

(firefox:7517): Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.
Error: no display specified
ravbholua@ravi:~$ sudo gparted

(process:7536): Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.

(gpartedbin:7536): Gtk-WARNING **: cannot open display: 
ravbholua@ravi:~$

The same error while opening calculator as below:

Code:

ravbholua@ravi:~$ type  xcalc
xcalc is hashed (/usr/bin/xcalc)
ravbholua@ravi:~$ xcalc
Error: Can't open display: 
ravbholua@ravi:~$

How to get my GUI working so that I can open firefox,etc on the remote
server (VPS)

Have you installed xorg?

ravisingh1 · 09-07-2013, 11:47 PM

I just now checked and found that xorg isn't installed.
So, shall I proceed ahead and install xorg.

Yes, if you want your desktop to work you will need some sort of display server and until Wayland (or Mir) is released xorg is it.

Thanks k3lt01
But the foll. command isn't working. How to install then xorg?

Code:

ravbholua@ravi:~$ sudo apt-get  install xorg
Reading package lists... Done
Building dependency tree       
Reading state information... Done
xorg is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 26 not upgraded.
ravbholua@ravi:~$

The way I confirmed xorg is there or not is:

Code:

ravbholua@ravi:~$ type xorg
-bash: type: xorg: not found
ravbholua@ravi:~$ which $_
ravbholua@ravi:~$

ravisingh1 · 09-08-2013, 12:48 AM

I installed xorg as mentioned in the below link

But the problem remains!!
And I think xorg was already there.

Why are you using sudo? just so you know when opening anything graphical (gui) it is best to use gksudo or gksu but you shouldn't need it anyway if you are logged in. I can open iceweasel and banshee using a normal (not root) terminal with out using su or sudo.Try it without sudo and see what happens.

I told the VPS provider of mine to look into the matter and here is what the reply:

You can not rung firefox or any other GUI application from the command line. You will need to install some GUI client as VNC on NX and log in the the VPS desktop and after that you will be able to use the server as a PC. I will suggest you check and use www.nomachine.com

Admin

I went through the site nomachine.com. I am in doubt as to which one to download among the options. Please see the screen shot regarding my system.
Do I need to select:
NX Free Edition for Linux - x86_64 > NX Free Edition for Linux DEB amd64
My local and remote box has ubuntu13.04

You don't need Xorg on the remote machine to get this working, you also don't need VNC or NX, SSH will be enough. You only have to enable X forwarding in your SSH configuration (don't forget to restart the SSH daemon after the change in the configuration) and then connect to the machine using

Code:

ssh -X

or

Code:

ssh -Y

Thanks a lot TobiSBD.
It's working. You entered the thread at the very right time. I opened firefox as well as gparted. Though I had doubt how w'd I feel surfing in my remote server (via browser) with my slow speed here locally. But it was good.

It took much time to open firefox (many minutes) though but once it opened , it was all O.K. after that. Browsing experience was fine.

But while opening , I got the output as below. What's missing?

Code:

ravbholua@ravi:~$ sudo gparted
[sudo] password for ravbholua: 

(process:1287): Gtk-WARNING **: Locale not supported by C library.
	Using the fallback 'C' locale.

** (gpartedbin:1287): WARNING **: Couldn't connect to accessibility bus: Failed to connect to socket /tmp/dbus-l6jTeueeGH: Connection refused
======================
libparted : 2.3

Code:

ravbholua@ravi:~$ firefox

(process:1307): GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed

(firefox:1307): Gtk-WARNING **: Locale not supported by C library.

I get the GLib-CRITICAL error whenever I open Firefox and have done for some time. As I understand it it's a known bug that isn't been treated with any urgency because the only thing it causes is that error message.

I am wrong to say this. sorry for that but it isn't my fault even because that way only things were presented to me.
The GUI (browser,vlc player) is so slow that one can't work at all. I don't think I should mention that here as it is slightly out of topic and w'd make this thread lengthy.
so, I am mentioning it in the below new thread:

(I am trying GUI client (www.nomachine.com). Lets see how it works.)

Sorry I didn't see you mention the server was remote, even though it is plain as day.

If you are already using a desktop why are you trying to open a graphical application on the server? Is this a thin client setup or something similar?
