Ubuntu Servers :: Install A Minimal X/windows Manager On Server - Can't Open Display
Sep 18, 2010
trying to set up a very minimal X on my 10.04 64 bit version of Ubuntu running nothing but Open SSH and acting as a firewall/router, making a PPP connection. The reason, is that I want to set up KVM/Qemu and run a virtual machine. The virtual machine will have a graphical environment and will be connected to my TV so that I can watch movies, stream TV etc. using it. So far, I have done the following:
sudo apt-get install xserver-xorg xserver-xorg-core miwm
When I try to run miwm the error message is:
(null): can't open display.
I have no DISPLAY variable set, but even when I set one myself using export DISPLAY=:0.0 it makes no difference.

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

After a long time I tried ubuntu(9.10) again on my fileserver, I have some remarks; why does a minimal server installation include X/openoffice? I don't need document conversion on a fileserver and I bet a lot of people don't. Wouldn't it be better to create a new server package and leave minimal minimal? low memory installs (64mb) don't work unless you configure swap by hand in between things, 64mb ram is a lot in my eyes. I mean, not to be rude but if I wanted all this I could've better installed Solaris.
That said it's stable and running fine. Since it's my home fileserver I tried to convert my previously created raid10 mirror on an adaptec 1200 card to a softraid 5 solution. This is wat I did:

I'm trying to create a media box for my TV. I've installed a barebones ubuntu from minimal install disc. After that I installed xorg and XBMC. But my usb devices are not automounting. Is there a pacakage im missing? I've read that XBMC should be able to handle mounting of devices and that no window manager or desktop environment is needed to handle this.
I followed these two tutorials and my current install is 10.04 Lucid.

Current version of XBMC is 10.0

I am trying to set up a simple home file-server for media and backups, using an old Atom board I had lying around and 1GB memory, so I don't want a full desktop. All goes well with installing server 10.10, using LVM for my data disk. However, I wanted some GUI tools since I am not familiar with the CLI, so I installed gdm, xorg, and gnome-core as suggested in some threads and forums.So far so good, it boots into the Gnome desktop, but I can't get sudo access with anything (synaptic, gkedit, etc.) - always "incorrect password". I am fine from the console; I reset my user password, no luck; I set up another admin user, and that also works in console but not the desktop.I have no idea where to go next and can't find anything that works in the forum

As I do not want to entrust my firefox data Mozilla's Server and have a server runnig anyway, I wanted to setup a server which provides weave service. I found this and know from different sources of the web that this indeed works: [URL] It is a stripped down Weave server intended for personal use. All in all, it does not sound to complicated. The developer says
Quote:
You ll need a relatively recent php with sqlite, mbstring and json support, and apache, preferably running ssl. Give it a shot and let me know how it worked for you in the comments. I have Fedora 14. Only problem is that Fedora does not provide a php-sqlite package. For this I found a repo [URL] So I installed php-sqlite (as well as php-pdo, php-cli and php common) with
Code:
yum --enablerepo=remi intstall php-sqlite
In consequense all php releted stuff was replayed by remi provided packages. In addition I installed json to get JSON support. The author describes the setup quite easy as follow:
Quote:
SERVER SETUP
Add the following line to your apache config:
Alias /weave /<path to this folder>/index.php
Restart your apache server. Point your browser at h[URL]. Enter "blah" for the username and garbage for the pwd. Auth will fail, but it will create the db (you can cancel the subsequent request for auth). You should now see a file called weave_db in the directory.
You can create and delete users by running the create_user script.
CLIENT SETUP
in about.config, set extensions.weave.serverURL to [URL] You can run it under http, but this is insecure and not recommended.If I disable or set SELinux to permissive mode I can point my browser to [URL] Here starts the trouble. After attemping to login no weave_db is created. I tried even 777 permission in that directory. I can run the create_user script with php and add a user, but the database does not seem to be recognized, I am unable to login into weave service.

I am still learning the ropes on Ubuntu server. I am trying to set up samba, but when I use the "gedit" command, I get this error:
GTK-WARNING **: cannot open display
I had installed the gedit command by using apt-get and aptitude, but still no luck. I am using virtualbox to test Ubuntu Server 9.10.

I have a VM with Windows XP that is driving me crazy. Everything works great except the display windows (and networking, but that is a different story) I am open VirtManager and go to display the OS and the images will get distorted. I will open IE and scroll down a webpage and some of the text will remain still and others will move, leave an image of garbage. This makes it very aggravating to use. To clear the page I can shake the window (using the cursor not my hands) or move from one tab to another till it clears.. then if I scroll again I have to deal with it all over again.

I'm running Ubuntu 7.04 server on a low spec spare machine ( 500MHz, 128 RAM) but fancy a change. Basically would like a non-GUI, command line only interface, running SSH, Samba and a flavor of FTP. FTP must be set up so users only have access to their home directory and not to any other system dirs. In addition I may want to incorporate anonymous ftp login at some point. Any recommendations for both FTP and minimal server software ?

I am currently running ubuntu 10.10
I have a panasonic 50" and a samsung 23" both of which are 1080p displays. I have twinview setup so that the samsung is my main and the panasonic plasma is my secondary. For some reason every time I open a windows of lets say mozilla and it was maximized prior to closing before, it will "jump" (briefly display on the samsung monitor for a split second and then automatically move to the plasma) from my main display to the secondary panasonic plasma. If mozilla was minimized before closing prior and I reopen it will open to the samsung in the state it was in on the prior close (aka minimized), which is fine. Only when it was maximized prior does it "jump" to my secondary display.
How can I correct this issue? I would like to have programs open (and stay) in the display they were launched in whether it is the plasma or the samsung.

Ive recently installed OpenSuse 11.2 and chose to install gnome with KDE4. Having done so i'm using kdm4 as the display mgr defined in /etc/sysconfig/display manager. However kdm4 reveals all the user names which I don't really like. Ive tried others including console. After logging in manually ive typed startx gnome which fails. How do you continue to use kdm4 setting and omit the display of the user accounts

Are there any open source Virtual Machines which have web based administration. I am setting up Ubuntu 10.4 x64 and would really like to find a usable virtual machine manager. I really like Virtualbox but only the full version has web based administration. I have also tried VMware but it isn't open source.

I've been trying to fix this problem for over a month, on irc chats and searching google for forum threads, all leading me in different directions all bringing me nowhere. In trying to connect from my Windows machine I get the following error:Quote: Windows cannot access \ubuntu
Check the spelling of the name. Otherwise, there might be a problem with your network. To try to identify and resolve the network problems, click Diagnose. Well, clicking "Diagnose" is a huge waste of time.I've paste binned by /etc/samba/smb.conf file and it can be found below -[URL]... Also, when I am on the Ubuntu machine attempting to browse the machines on the network and go to Places >> Network >> Windows Network I get the following error: Quote: Unable to mount location Failed to retreive share list from server

I've done some searching around but can't find anything conclusive on this error. The tech at my remote site restarted the 9.04 server(not sure if it was accidental or planned) and when it started the boot process, an error like the following shows up...
"The display server has restarted 6 times in the past 90 seconds. This indicates that something bad is happening."

Clean install of 10.04 Server 32 bit.Only services OpenSSH Server and Print Server.Machine boots and can be accessed through ssh.Virtual terminals (cntl-alt-1,2,3,4,... do not result in video to the monitor (no sync) or a display.If I type blind, I can log in, ssh back to my other machine, and create a file. So the virtual terminal is there and listening to the keyboard and running, just not creating a display.
This machine has been working fine with 08.10 for quite time up until yesterday, so I don't believe it is a hardware problem.Any ideas why the video on the virtual terminals would not work?

Is there a way to select a second installed OS on a home server system without display and keyboard? I am putting together a home server (for mail, storage, media streaming) using an Atom-based Ubuntu Server 10.04 on a 4 GB intern flash drive and 2 hard drives for data storage, but no display or keyboard. I want to make periodic full backups of the system (flash) disk and use a second OS (installed on a partition on the hard drive) with a graphical interface (e.g. Xbuntu or PartImage) for maintenance purposes. I can connect remotely (from a Win7 or a Linux computer) to the X-display once the second system is running.
a) how can the second OS be booted on this server without keyboard? Is there a way to tell Grub2 to look at some hardware switch (or file) for the menu selection? The board has a serial and parallel port so I could wire up a switch to some pin of one of these. Also external USB connectors are available on front and back. Or can Grub2 read its default OS choise from some simple file, easily to change from a shell command of the eBox webbased system control internface?
b) I assume the second OS is needed to make a complete backup of the server OS on the flash disk. Can the backup be automated? (i.e. switch to second OS, backup, reboot first OS)

I am mainly a Windows admin, but I do *NIX administration from time to time, for now I need to use an open source solution for backup windows environment mainly, I spent last days playing with bacula and backupPC, and I then chose backupPC, I built a solution with it seems working not bad, but before i go on deeper, I thought asking geeks here better, my main experience with back was with Vertias/Symantec Backup Exec, what do you recommend as most similar backup solution in Ubuntu offer a close level (I don't backup to tapes I back to hard disks), also a gui is preferred, while backupPC do a nice work and i handled its client config file (machine_name.pl), but I still do mistakes sometimes and troubleshooting is annoying, I have to backup files from users machines some of these files are running (like PST files), and I could need to backup a database or something from time to time. so whats your opinion all?

I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'
From: [url]
I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?

I have recently resurrected an old X Windows application and I am having a problem getting a CentOS 5.3 client to run the application from a CentOS 5.3 host.
If I am logged in as root to the client side and ssh -Y over to the host, then run xclock, everything works just fine.
However, if after I ssh -Y over to the host, I then su - userx on the host, and then run xclock, I always get the "Can't open display" error.
I have tried:
Running xhost + on the client. doing the "xauth add display MIT-COOKIE xxxxxxxxxxxx" on the client & host, both as the root user, and as the userx. I can't seem to get a definitive answer as to which user and which machine (client/host) this needs to be run as.
Also, when you "xauth list $DISPLAY" you get nothing, (because it is either localhost:0.0 as root, or :0.0 as the su - user) you have to "xauth list", and then you get a list of cookies, but since the "echo $DISPLAY" doesn't match any of them, it is not obvious which one to use. Also, they are ALL "host/unix:X.0", so I assume they are all socket based, and as such I would assume that the their cookies would not be usable for remote TCP connections?
I also saw information about using netstat -anp to look for 60** LISTENERS, I could not find any on the client or host sides.
Nothing seems to work.
I heard about a program sux that is on ubuntu, but I could not find it for CentOS. Is there an equivalent on CentOS?
I have searched the web and found lots of info in forums all over the net with what appears to be the correct way to do this, still nothing appears to work.
What is confusing is that if the TCP LISTENERS were not there, I should not be able to get it to work as root either, so it must be in the transition of the su - userx.

I just performed a fresh install of 11.04 Server. The installation went smoothly and as expected. As soon as I leave the BIOS and Ubuntu boots, however, I lose my display (my monitor says "Cannot display this video mode"). I am able to ssh into the machine just fine, so I know it is booting up fine; I just don't have a local console.
Other threads related to this topic suggest adding something like "vga=771" to the boot options in grub/menu.lst, but I don't see that file anywhere in my 11.04 server install. Where can I configure display settings now?
I am using the following video card:
$ lspci -nn | grep VGA
01:04.0 VGA compatible controller [0300]: ATI Technologies Inc Rage XL [1002:4752] (rev 27)
