Ubuntu :: Infinite Startup Loop - OEM / Black Screen
Apr 18, 2011
I'm doing a dual boot Ubuntu 11.04 and Windows 7 on my Asus UL80v. When I restart and keep going into Ubuntu I'm fine, but I think if I go to Windows and then restart, the infinite start up happens, and I'm currently stuck in this. It'll go to the OEM screen, then a black screen with a cursor, then it goes black, and then back to the OEM screen and so on and so forth.
Luckily I have Ubuntu 10 on my flash drive, so I'm booting to that while I try to figure out this. Which reminds me, when I use the flash drive, there's an option to boot to local disk which also does not work, if that's worth anything. Before this happened, I ran check disk on windows because I ran into some partition troubles. There seemed to be no problems, and I can still access the drives from this flash Ubuntu.

I have just upgraded from 10.4 to 10.10 (x64), and now when I run gnu screen the new shell session goes into an infinite loop displaying:
Quote: Linux dave-desktop 2.6.35-22-generic #35-Ubuntu SMP Sat Oct 16 20:45:36 UTC 2010 x86_64 GNU/Linux
Ubuntu 10.10
Welcome to Ubuntu! * Documentation: [URL]...
0 packages can be updated.
0 updates are security updates.
repeatedly until I hit CTRL-C and break out of screen. I tried tmux and that did the same thing, so it is a problem with the shell initialisation rather than with the screen program. However I can start bash, zsh or sh directly in a terminal with no problem.

i was playing around with c++ recently and for laughs and giggles i came up with this little program
Code:
#include <iostream>
using namespace std;
int main ()
{
[Code]....
theoretically that should be an infinite loop but it in fact does terminate eventually echoing out 'FIRE!'
just wondering if even though in theory this should be an infinite loop (a number repetedly divided by 2 should never reach 0 thus the conditions of the loop should never be satisfied, hence infinite loop) perhaps in practice limitations of the variable types prevent this?

When I boot one of my machines, it gets as far as GRUB, then proceeds to a blank screen for a second, and then repeats the cycle all over again - ad infinitum. I have tried previous kernels on the list with the same results Also, I cant boot into recovery mode either.
I have run Memtest successfully from the GRUB options and no errors appear in the results. I have tried booting from a Live CD and here I get as far as the "OS choosing screen". When I then select one and hit Enter, the screen goes blank and the machine reboots as before.

I upgraded to 10.10, system rebooted but it is stuck at a constant loop.
I can go into safe graphics mode and things look fine except compiz isn't running. I have tried going into login and changing it to log me in automatically but the problem remains.
I've tried using my previous kernal and I have the same issue as this newer one.
I've tried loading gdm from CLI and the problem is still there.

I installed Xubuntu and was thrilled to see that it had already setup my Brother HL-2140 USB laser printer.However, there is something seriously wrong with the setup. When you try and print, even a test page - it just churns through the entire paper tray printing nothing. Also, when you restart the computer it tries to print the jobs again. I went to Printing and selected the printer but could not find where you could see the print job queue. I did see it during troubleshooting and was able to delete the jobs on the troubleshooting screen.

I think i came across a bug in X server in squeeze. I would report it to the bug tracking system in debian packages but the think is I am not entierly sure about it.When i start X (whether it is through startx or service gdm start or auto startup through init when the pc boots) the computer PC seems to lock up.The screen goes black right after X initializes and before anything is show in the screen and if i wait a about 10 minutes the monitor either goes in standby or out of range. PC seems unresponsive to both keyboard commands and mouse but my LCD screen in my G15shows the time skips 1 sec every 2 sec (from 19:22:22 goes straight to 19:22:24).
I have a custom 2.6.33 kernel which i build but it happens with both 2.6.32-trunk and 2.6.32-3 offical kernels from the squeeze repository so i dont think that this is the problem.My PC is a P4 3.75Ghz with 2Gb RAM and an NVidia 6800GT with the binary drivers from nvidia. I have tried diffrent versions from my grapgics drivers (NVIDIA-Linux-x86-173.14.25-pkg1.run & NVIDIA-Linux-x86-195.36.15-pkg1.run) with no change in the behaviouThis is the syslog from the time my pc started and then "stuck". I left it for some time before i hard reset it

I want to figure out what is going on in this small script.Its really strange.I think its the infinite loop again.All I want to do is to collect some data from the zenity dialog box in an array and then echo it.Here is the code
Code:
#!/bin/bash
#export PS4='+${BASH_SOURCE}:${LINENO}:${FUNCNAME[0]}: ' debugging info

I am trying to develop a process monitor, or use existing monitors to achieve the below given actions.
1) Restart a processes if it crashes.
2) Restart a processes if it is stuck in an infinite loop.
The sample code below describes the structure of the process.
while(1)
{
statement 1....
statement 2....
while (1)
{
[Code].....
The goal is to restart the process if it is stuck in a loop, inside the outer while loop. Given this scenario, what would be the most efficient way to monitor such a process?
A sample solution would look something like this: statement 3 will write to file1 every time it is executed and we know that the maximum execution time of the outer while loop is 30 seconds. A second, timer driven process, checks for file1 being modified every 30 seconds. If the file is not modified, process 1 will be restarted assuming, process1 is stuck in a while loop.

I have a java server console program that I have configured xinetd to start when connection comes in on a given port and then the program runs in an infinite loop receiving inputstream from telephone exchanges. The thing is, when a new chunk of stream comes from the exchange xinetd forks a new process each time. I tried setting the wait parameter to yes and restarted the deamon, but no success. How can I stop this behavior and have the deamon just direct the stream to the process already running? Am I missing something in my config or is it just incorrect?
My config is as follow:
defaults
{
instances = 60
log_type = SYSLOG authpriv
log_on_success = HOST PID
log_on_failure = HOST
cps = 50 10
}
includedir /etc/xinetd.d
And then my actual config,
service aos_larmar
{
socket_type = stream
protocol = tcp
user = root
type = UNLISTED
wait = yes
instances = 256
server = /home/gunnl/java/start.sh
port = 5204
disable = no
}
My server OS is, Red Hat Enterprise Linux ES release 4 (Nahant Update 7)

It happens really randomly. Suddenly keyboard and mouse stop to react. Screen freezes. However if I have for instance skype running during that "crash", I can still continue to talk over internet. For me looks like x serwer crash. Xorg logs however are empty. I had to hard reboot only to get control over pc (magic sys key + SUB) only works. Trying switch to another session is not working. I run Slackware 13.1. Kindly asking to help me to solve that irritating issue. I pasted errors usually I find at Xorg.0.log.old after hard reboot only

I have recently been running into the "EQ overflowing" message. It has been happening when I open an image with gimp or a xls with open office. I noticed some were having this issue with earlier kernels. I am using the nouveau driver to run two nvidia cards with three monitors. I am currently running the 2.6.34.6-54.fc13.x86_64 kernel. Here is the output of my Xorg.0.log file:

Fedora 15, fresh install.I changed the wallpaper from default to a solid colour. After switching between gradient to colour the system crashed logged me out and upon logging in it simply runs endlessly accessing my harddisk but never actually loading the desktop.I can kill X and reboot, but it's the same problem waiting for me on restart. I really don't want to re-install or delete users (to put it in context, I just spent 3 days trying to install Fedora because Anaconda doesn't know how to install GRUB correctly).

Recently my laptop running Ubuntu 10.10 has had an abrupt power shutoff (actually several times -- my battery has some problems).
Now when Ubuntu boots, I get the startup screen, but after a few seconds, the screen goes black. I can still boot from the live CD and in fact I am using my computer from the CD to write this post.
A few more details: When I press the power button while my computer is in this "blank" state, I get hard drive activity. Also, if I press "power", and then "enter", the machine actually shuts down.power

HP laptop with Intel graphicsunning Slackware current with a 2.6.38.7-smp kernel.Booting with the "nomodeset" kernel parm works but X gets stuck with a 1024x768 resolution. When booting without, the screen goes black after a few pages scroll by, just at the point where the console switches to a higher resolution. Changing to a different console didn't help, so I blindly log on and type startx, and the screen comes back to life with KDE running at the higher 1366x768 resolution, I try a few apps, the webcam, suspend to RAM, resume, and everything is now working flawlessly so it doesn't look like an X issue.At this point I can change to another console (or exit KDE altogether) and the screen is back on at the higher resolution. Looking at the X log and some dmesg output makes it seem that starting X possibly replaces, reloads or unloads a driver? If this is the case, how can I prevent the conflicting driver from loading in the first place?Quote:
dmesg |grep drm
[ 11.481967] [drm] Initialized drm 1.1.0 20060810
[ 11.637941] [drm] MTRR allocation failed. Graphics performance may suffer.

I'm having problems with the screen going black on startup in 10.10. It appears to go completely off (no backlight or anything). If I press ctri+alt+f1 I get a terminal, then I can ctrl+alt+f7 and the desktop appears. I have tried setting the mode to the correct resolution in xorg.conf and I tried using the vesa driver, but it still doesn't work. My graphics card shows as sis 661/741/760

I'm having a problem with a server I just got. The first thing I did when I got it was to format the drive and install ubuntu server, but on booting up I got a black screen and my monitor (samsung syncmaster914v) displayed a bouncing notification with the text "not optimum mode recommended mode: 1280 x 1024 60hz". However at one by using a combination of plugging in the monitor after booting, and pressing random keys on the keyboard I was albe to boot into the server, and was able to access the monitor meu, which told me it was running at 640x480, and 60 hertz. having access to the console I stupidly tried changing the resolution and then rebooted, getting the same black screen.

Not beeing an expert on Ubuntu, but loving it running on my old Dell Dimension 2400 Series, I do have some issues after the upgrade to 9.10.
1) Frozen screen after a while working with the system. Cursor moves, but frozen
2) Black screen at startup.
Retyping this message again on my Mac Laptop as Ubuntu froze again. I took the following action: Followed directions as listed here [URL]
1. Select recovery mode from the boot menu.
2. Select login as root from the menu in recovery mode.
3. Type this at the prompt
# sudo apt-get remove xorg-driver-fglrx
# sudo dpkg-reconfigure -phigh xserver-xorg
4. Exit
# exit
5. Now select Resume normal boot from the menu.
Every thing should be OK by now. This seemed to work, but after another reboot, black screen again. System Specs: [URL]. Running with 1 GB of Memory and 320Gb Hard Disk /w 2Gb Swap and 318 Gb Extended.

I just stupidly changed my graphics resolution in System - Preferences - Startup Manager, now i dont get a login window or anything just a black screen. I also disabled the splash but i assume this just gets rid of the ubuntu loading line thingy?
the weird thing is that the resolution was set to 640x800 or something like that in the Startup Manager as default and the laptop im using (an old Toshiba Amilo P4) supports 1024x768. the System - Preferences - Display menu wouldnt let me change any display settings which is why i was messing about here. I havent got any backed up x org file and only a live usb of super os/ubuntu - no cd or floppy drive.

I am running ubuntu 10.4, windows 7, and I had ubuntu 10.10 on a single hard drive. I upgrade the 10.10 system to 11.4 and now my grub menu which is on the 10.4 system shows two windows and two 11.4 installations.
How can I clean this up? Also I have tried to start with the grub 1.99 on the 11.4 system and all I get is a black screen at startup. I am happy with grub on 10.4 except for the extra lines.

I have installed Debian Jessie 8.0.3 64-bit net install on a MSI CX620. Installation went fine but trying to boot it up the first time nothing but a black screen shows up. I've tried:
Holding shift on startup - Nothing
Press down all keys - Not much, only ctrl+alt+delete makes the screen turn off and then on again.
I'm thinking that I had secure boot on which I now after installation see could be a problem, but I didn't think it would be a problem as I could just go into bios and turn it off, but seeing now that I can't even go into bios it may be a problem.

I was messing around with the screen orientation and thought it would be funny to orient it sideways. Big mistake The screen went black.I can force a shutdown, login and I get the same black screen. I tried hooking up an external monitor and the monitor showed no input so I'm guessing my laptop doesn't have that capability with Fedora.This is my main computer.
