I have an Ubuntu Linux 10.04 installation which I would like to use via remote desktop. Everything works perfectly if I start the computer with a monitor attached. If I do not, X fails to start because it cannot find any screens.
How can I force X to start up without a monitor attached?

He wants to access via VNC which isn't a problem as I've got that sorted.Problem is, the PC is sitting in the computer room with just the power and lan connections, no monitor etc. When I boot the PC with a monitor attached you can VNC into the server, but if I boot it without a monitor attached, VNC doesn't work?Any ideas how to get it so it always works when a monitor is not attached?[URL]
View 4 Replies View RelatedI just upgraded to Ubuntu 10.04 yesterday on a headless home server. I use the server for a variety of purposes, and what I don't know how to do via SSH I've alway been able to do through VNC. However, since the upgrade vino-server will no longer run if there isn't a monitor attached. Before it used to start up without a problem. Even by attempting to run the server via SSH gives me a "could not load display" error. Summary: I need to get vino-server running at boot time on a server with Ubuntu 10.04, without a monitor attached.

I'm running Fedora 11 GNOME as a server and I do not want to attach a keyboard, mouse or monitor. I will be shutting down the server at night to save electricity. But, I noticed that when I start up the system the next morning, the auto-login won't work until a monitor is attached. how to get the server to automatically log itself in without monitor attachment? I'm going to use the server to access my fileS remotely through Samba (which I can still do). But, I also want to have VNC functionality so I can remote desktop in to the system at will. I can access my files ok through Samba without the computer logging itself in, but I can't remote desktop in with VNC.

My question is how should I configure the xorg.conf file so that when I attached external monitor, the GNOME menu bar (Applications, Places and System, etc) will be put on the external monitor instead of laptop LCD monitor.
I have checked varies web resource that saying you can drag and drop the GNOME menu bar to the new screen, it never worked. Someone also suggested to add new bar into the screen and GNOME will remember it, I can't even find the option to do that.
since upgrading the squeeze kernel from 2.6.26-2-686 to 2.6.32-5-686 Iīve been unable to boot my HP D510S/845G without attached monitor. As this computer serves as router and print/faxserver, there is/was neither a monitor nor a keyboard/mouse attached. With monitor everything works fine, without monitor the computer hangs somewhere. Unfortunately it hangs without logging anything in /var/log.
Reinstalling xorg and xserver-xorg didnīt change anything, neither was the new xorg.conf from dpkg-reconfigure -phigh xserver-xorg of any use. (After booting with attached monitor I disconnected the monitor and ran dpkg-reconfigure) Maybe disabling Xorg would solve the problem, but I want to be able to log in via vnc and use a GUI - for example to configure mythtv. Up to the kernel-update everything was working fine, so I think some changes to the new kernel are responsible. how to fix it or how to start logging earlier in the boot process?
I've put a fresh install of Fedora 13 x86_64 on my new server and I have it automatically log in to the gnome desktop so I can control it via VNC. However this only happens when there is a monitor physically connected when the computer boots. If there is no monitor present at boot time, there is no graphical session started, however I want it to start whether or not a monitor is present.
My hardware is a Zotac IONITX-G-E board (which has an Atom N330 and a NVidia ion chipset of some description). I'm using the Fedora default graphics driver (nouveau). Why doesn't it start a graphical session with no monitor, and is there any way to get Fedora to start one whether or not there is a monitor connected?
I can''t make the machine booth when a monitor is NOT attached to the machine. The PC seems to get past the P.O.S.T with minimal HDD activity, and then it simply hangs there, doing nothing. I know Linux is not booted because the HDD flashes briefly only 3-4 times and then absolutely nothing. When a monitor is attached, everything works perfectly.
I read somewhere that this happend when GRUB tries to display graphics, so I edited the menu.lst and removed the graphics line within it, which causes GRUB to display a B/W clear-text boot-menu (when a monitor is attached), but the machine still won't boot with no monitor. I also edited inittab to boot to level 3, same outcome.

I am running a server that is mostly headless, but does run the Gnome environment (I have ubuntu-desktop installed). I usually administer it via VNC over SSH. My problem is that when I reboot the system over SSH, the system fails to fully load the GUI, which prevents me from connecting via VNC (although SSH still works).
When I connected a monitor and rebooted, the system booted up fine. It appears that the GUI will not load without an attached monitor, which never happened before in previous Ubuntu versions. I do use many commands but prefer a GUI for certain tasks and visualization of my work since my system has the resources to spare. Running Lucid Lynx
I have developed a website. Now i would like to monitor the IP address of machines who are accessing the server. The simplest possible solution to this that comes first into my mind is to use jsp inbuilt tags.
Code:
<%
out.print( request.getRemoteAddr() );
out.print( request.getRemoteHost() );
%>
but it has given me some other IP address(May be a proxy server's ip address)
So i was left with one choice is to run netstat on host server . Here is what i have done.
Code:
netstat -an | grep 8080 (As tomcat runs on port 8080).
Should i modify the command or there is any other way around to monitor the IP address?
I installed a copy of Debian Jessie server and then tried to install a light GUI, specifically XFCE4. I am accessing my installation directly via a mouse/ keyboard and monitor, not remotely. After installing the Debian server software, I ran the following commands: apt-get install xfce4
It all appeared to go well, with no error messages. I then tried to launch the XFCE4 interface by running the following command: xfdesktop.However, all I get is the following error message:Failed to parse arguments: Cannot open display.what I need to do here to succesfully launch XFCE4?
Does anyone know of a tutorial or site where I can learn how to monitor what sites people have been accessing on a network?

This is apparently a known problem. Has to do with disk idling not implemented correctly.

View 4 Replies View RelatedI have been using Linux and Ubuntu only since the last two months on my (2006) Sony Vaio VGN A617S laptop which is going pretty well on Ubuntu 10.10. When installing Ubuntu audio did get installed alright, and the speakers on the laptop itself are working well even now with the right drivers (snd-hda-intel) for the Realtek ALC260 soundcard.
My problem is when laptop is docked to the A/V docking station (I have seen it referred as a port replicator as well - the model number is VGP-PRAV2), with its two external speakers. And these were not on when Ubuntu was being installed. What is interesting is the headphones jack on the laptop does work when the docking station does not. I have been trying hard and have already tried quite a few things I saw to be related issues, like:
a) adjustments to some IEC958 in alsamixer
b) using a custom mod for the ALC260 card
Currently I have two 1920x1080 screens running in Twinview on my Geforce 275 graphics card. Want I want to do is a quick simple way of disabling my secondary monitor when playing video games or using xbmc to watch movies, etc. I've tried a few applets but they require the xandr function which I think Nvidia doesn't support.
Is there a way to disable this quickly other than loading up nvidia-settings and disabling the monitor everytime. I don't really want to use two seperate x sessions and xinerama due to the fact you can't use compositing.
I need to say that this is not my computer, so I don't know all of the details, but I know all it is really used for is Internet and reading .pdfs, and the main user is not an advanced user at all, so he wouldn't have messed with anything important. The picture pretty much says it all. It does not look like this at startup. This computer is set up to go to sleep after 15 minutes, and sleeping is how it spends most of its time. I don't know if sleep is what causes the problem or not. It just does it randomly after some time. The only way to fix it is to restart the computer.

I'm running Lucid and have an annoying problem with Rhythmbox: while playing, it constantly accesses the disk, every 2-3 seconds drrrrd drrrrd. Listening to some silent music is horrible - the output of the speakers is lower than the noise of the local disk.
Maybe relevant settings in Edit->Preferences:
Playback -> Network Buffer Size: 1024 kB
Music -> Watch my library for new files: off
Is there anything else one can change? It can't be that difficult to read a <10MB file into memory right from the start and not touch the disk drrrrd every few seconds?! P.S. I verified by turning off the speakers and start/stop playback - the noise there on playback and not if turned off. Reliably.
Is there any program to create databases graphically? Something like Glom maybe?

View 6 Replies View RelatedI'm using Fedora 15. For some reason, my computer is booting up graphically. I do not have video drivers for a graphical setup apparently now that Gnome is getting more advanced, so I really need to restore to a CLI. I see /etc/inittab is now deprecated thanks to systemd. The instructions say the following:
Code:
# Ctrl-Alt-Delete is handled by /etc/systemd/system/ctrl-alt-del.target
# systemd uses 'targets' instead of runlevels. By default, there are two main targets:
# multi-user.target: analogous to runlevel 3
# graphical.target: analogous to runlevel 5
To set a default target, run:
# ln -s /lib/systemd/system/<target name>.target /etc/systemd/system/default.target
And that's exactly what I have set up!
Code:
[root@server system]# pwd
/etc/systemd/system
[root@server system]# ls -la
total 20
lrwxrwxrwx 1 root root 37
May 31 10:41 default.target -> /lib/systemd/system/multi-user.target
Why is this machine starting up graphically? I even removed the symlink and recreated it... but that obviously isn't the issue here.
There is a test/development environment here at work with some windows and some CentOS systems connecting over a network share to a CentOS fileserver in the data center. The developers run as root (i know i know, but the environment is completely cut off from the rest of the company and this just worked best) and connect to the fileserver using samba. I tried using nfs but to no avail. Now, a couple of the developers have no issues with permissions at all but a couple of them are not able to delete files or folders in their network share graphically. They can through terminal though.
