Ubuntu :: X Wont Start When A Monitor Isn't Plugged In At Boot Time?
Jun 18, 2010
I have a system I use as a file server running Ubuntu 10.04. I don't have a screen hooked up to this system. When this system reboots, if there is no screen, X wont start on it. This then prevents me from using VNC to get to the desktop.If a monitor is plugged in at the time it boots, then everything works, and I can then remove the monitor. But moving this monitor between computers and crawling under desks is not enjoyable.How can I fix this so X starts on boot even when no monitor is plugged in?The error I get in /var/log/Xorg.log* looks like this:
grep -EnC2 "EE|WW|fatal|error" /var/log/Xorg.0.log
...
331- (II) Primary Device is: PCI 01@00:00:0

I have an old computer (Pentium 4) without a monitor. To make the most of it I installed Ubuntu server on it and have been using it for almost a year. A couple of months ago I don't really recall what I did but since then it doesn't start-up unless a monitor was plugged in.
I've tried pinging it but it doesn't respond when no monitor is plugged in. meaning it's not even booting correctly.
I'd like to know what the problem is and how to fix it. And I'd really appreciate any help in diagnosing the problem. I just don't know where to start.

The computer is used as a server and I connect remotely on it with VNC. It has no monitor. It was working fine until I upgraded to Lucid. Now, it only works with a basic vesa driver (800x600 max res). The log says:
NVIDIA(0): No display devices found for this X screen.
Screen(s) found, but none have a usable configuration.
If I plug a monitor, it work fines. Is there a way to disable monitor detection?

I am trying to build a media pc, and successfully so till this one little/big problem. I want to be able to turn on my tv, and pc, and have the pc display onto the TV. Ports used are HDMI(pc)->HDMI(HDTV)
But for some reason Ubuntu will not fully load with just the TV plugged in (all i get is a black screen, not even a "no signal" message).Once a LCD monitor is plugged into the VGA port. Then I see a glossy white Ubuntu symbol on the LCD monitor. Then the Ubuntu loading screen appears on both the LCD monitor AND the TV. in mirror mode. And I can see the desktop on both monitor AND TV.
I am using an ATI RAEDON HD 4200 chipset that is on the mobo. I have downloaded the proprietary drivers and installed them. A few things I have tried are the instructions on this page, finding my modeline using a modeline calculator and also going off of a suggestion from a thread on this website, stripping down my xorg file so that the Xserver would autodetect it. Which i think I did wrong because after that, it wouldn't display on TV at all.

I have installed "open-SUSE 11.4" on a "500GB Free Agent External Hard Drive". I didn't have any problem in booting since last week that I booted it from my laptop. Also I did it before several times from then when I try to boot it e.g. from an "Intel(R) Core(TM)2 Quad CPU Q9400 @ 2.66GHz" PC the time between loading INITRD and starting boot sequence messages lasts nearly 30 minutes!(i didn't actually measure it but it take a long time in the same order). after starting boot sequence which is showed on monitor everything looks normal. e.g copy of files would be done by speeds between 2MB/s to 30 MB/s depending on the targets.I used to use the external hard derive to boot from different laptops and PC's from start but I didn't have such a problem anytime.

Does anyone know a way (hopefully a standard/generic way, e.g. through sysfs the interface) to determine if a VGA monitor is plugged in on Linux?

I have an Asus eee901 netbook and it's got an Intel 945 graphics card. If I boot it up, log in, attach an external monitor and then open the Display Settings dialog the screen goes black and the laptop appears to crash. Leaving it for a minute or two does nothing.
However, if I boot up with the external monitor attached then I can open the Display Settings dialog and configure both screens.
This is quite annoying as I've got to reboot if I want to connect an external monitor.
Additionally, if booted with the monitor attached and I choose a configuration where the width of the combined screens is greater than 2048, the screens go black and the same lock up appears to occur. Could it be that the Display Settings dialog isn't checking for the maximum display width the driver supports and is then crashing in both scenarios?

I installed and configured privoxy - everything worked nicely when I run it manually by
Quote:
/etc/init.d/privoxy start
After restarting the computer privoxy wasn't start automatically. I checked the links in /etc/rcX.d - are o.k. I installed sysv-rc-conf - shows that for runlevel 2 - 5 privoxy is running. I changed /etc/rc2.d/S20privoxy to /etc/rc2.d/S99privoxy - to start that process at the end. I installed Boot-Up Manager. Privoxy is marked for start automatically. I added in /etc/rc.local line: /etc/init.d/privoxy start
Privoxy still doesn't turn on at boot time and every time I must start it manually. Could you tell me how could I repair this ?

What's the best way to register a daemon to start up at boot time in lucid? I have tried registering the following script using "sudo update-rc.d"
Code:
This is supposed to get the daemon for opentftp started, but it does nothing, although I can see the results of the "echo 'Server opentftpd started' " in the boot log in /var/log .Any thoughts or general help on what the best way to accomplish such a task is?

I'm running Debian Etch AMD64, and currently trying to clean up my system in preparation for an upgrade to Lenny. One problem I have is that resolvconf (which is installed) does not start at boot time, but if I start it manually then bring the NIC down and back up, it works OK, with no error/warning messages.

I try to start openoffice in server mode so a CMS can use it to convert documents. In a shell I can call
/usr/lib/openoffice.org3/program/soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard -display:1 &
and it starts successfully and the CMS can use it. To start OO at boot time, I wrote a script called 'openofficeserver' and saved it to /etc/init.d. It looks as follows

I am running Debian-Squeeze with apache2. However, apache2 doesn't start at boot time, even though there is of course the required script in init.d. I can start it later on using "/etc/init.d/apache2 start". I have checked the configuration with "apachectl configtest" - giving the answer "Syntax ok". How do I get it to start automatically at boot time?

Arpwatch is failing to start at boot time. I got this message:
arpwatch: bad interface eth0: eth0: no ipv4 address assigned
Once I login into my account, I can (as root) run the arpwatch demon, but it is suppose to run at boot time. After I installed aprwatch, it was working correctly. I do not have an idea of what happens or since when the problem start to happen. I just realize, after a while , that arpwatch was not running. I am running Fedora 12 - 2.6.32.9-67.fc12

I need to start an application (graphical) when the PC start, even before anybody login, and use/launch a specific user. Now only can do this manually; when gdm starts, switch to any text tty [ie. Ctrl + Alt + F1], then I login into the special user, start a X server, export the DISPLAY environment variable, and start the application.
With this steps:
Code:
$X :1 -verbose -nr -nolisten tcp &
# Maybe Metacity -> $ metacity
$export DISPLAY=:1
$JavaApp &
Now i need put this steps (script) in some place to launch the app automatically, and with and specific user [ie. manager].
How can I made it? Maybe in init.d? or an special xinitrc? And how can start the app with the specific user? And, if is possible, who can stop the app when the system going turn off? I have Debian 5.0 and a beginner knowledge of shell script.

I've been troubleshooting a friends computer and we've pretty well hit a brick wall. The issue at hand is the video card will not output properly. To be specific, it's an NVidia card with both DVI and VGA ports. We want it to output via the VGA and ignore the DVI because there's nothing plugged in there (the monitor we want to use doesn't support DVI). At any rate, the only time we can get the VGA to work is when we have another monitor plugged into the DVI port and dual head the system. When we do this it also adds an extra "Unknown Monitor" to the display panel. When we just use the DVI the extra "monitor" disappears. now we don't want to have monitor sitting here useless just so we can use the vga out, but there seems little else to do. We tried installing the Nvidia proprietary drivers through the software manager and yum and it failed both ways.
This is really frustrating because it seems like it should be such a simple thing but nothing works. Does anyone else have similar issues? is there something i can do to fix this? I apologize if i've not provided enough info, but ask and i'll post anything you need to diagnose.

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.

It takes me a while to log in the splash screen just sits there for ages before i get to the desktop. Never used to be this slow and I'm not sure why. Firstly, I'm running Ubuntu 11.04, standard DE. I do have conky starting up in a script but it has the & at the end of the line so I didn't think this would cause it (or is there some special case for log in time on how & is treated?). However as a test I will comment out the line in the script and see if it is the cause.
However just for general knowledge and in case that isn't the problem, how does one go seeing what is happening during the time from when one log's in and the desktop is displayed? Is there some kind of log that shows the date/time that can be enabled or is there a debug mode that can be enabled somehow via special keys or maybe from grub?

Since I bought my computer and I installed Linux on it, I had this problem...
Back in the day I never Found a REAL Solution and finally my "solution" (in Fedora)
was installing "pavucontrol" to choose the Devices when I needed to Switch.
Via the Pulse Audio Volume Control I was able to Mute speakers or Headphones
at my will, even if I had both connected, this thing worked from F12 to F14 very well...
(The same problem is present in every distro I tried and sometimes it was solved the same way in other distros)
But Now, I'm in F15 And my magic workout doesn't work anymore... it doesn't matter
wich device I choose as output, the PC simply don't mute one or another and my headphones and speakers sound at the same time.
The Sound card is a HDA INTEL with the Realtek ALC662 rev1 Chip, as I said before,
I'm using Fedora 15 KDE (64 Bit version) and I'm running ALSA v 1.0.23 with pulseaudio 0.9.22-5
The output of "lsmod | grep snd" is:
snd_usb_audio 98871 1
snd_usbmidi_lib 18066 1 snd_usb_audio
snd_rawmidi 20308 1 snd_usbmidi_lib

I just did a distribution upgrade on my laptop from 9.1 to 10.04, and it went fine for the most part except this issue. After it boots up, I don't see any window titles/scrollbars/borders and on clicking the icon for "Show desktop" on the bottom left, I see the following error message:
"Your window manager does not support the show desktop button, or you are not running a window manager."
After googling a bit, I realized that gnome-wm is not starting automatically and so I have to manually start each time to see the windows working properly. Can somebody tell me if there is a way to make sure that gnome-wm starts automatically? I know I can put it in my .bashrc but I want to do it the correct way if possible. If not, I will have to go with that workaround.

I have installed Fedora10 on my PC which had an XP. Now Fedora waits just 2-3 seconds to press any key to choose between XP and Fedora. Actually if I don't press any key it automatically begins Fedora. How can I increase this time interval?

I am trying to get mysql to start at boot without any success.
The mysqld scripts works fine when run from the command line, but it does not work when i use the links created by chkconfig. I checked the boot.log and found that mysql starts but then it stops or gets shutdown. This is the log message:
Starting mysqld daemon with databases from /data/mysql [ OK ]
Starting cups: [ OK ]
STOPPING server from pid file /var/run/mysqld/mysqld.pid
starting DenyHosts: /usr/bin/denyhosts.py --daemon --config=/usr/share/denyho
sts/denyhosts.cfg
090727 04:35:47 mysqld ended
The same init script works fine in Ubuntu.
