Ubuntu :: Infinite Boot Cycle Loop After Grub

Jan 26, 2011

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.

Programming :: Infinite Loop That Isnt Infinite?

Oct 27, 2010

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?

Ubuntu :: Stop The Infinite Loop Splash Page In 10.10?

Feb 15, 2011

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.

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.

Ubuntu :: Printing Gets Infinite Loop Of Blank Pages?

Jun 25, 2011

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.

Debian Multimedia :: X.Org Infinite Loop Bug In Squeeze?

Mar 25, 2010

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

Software :: Detecting An Infinite Loop In A Process?

Apr 1, 2011

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.

Ubuntu Installation :: Screen Shell Goes Into An Infinite Loop After Upgrading To 10.10?

Oct 20, 2010

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:

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.

General :: Xinetd Server Configuration - Infinite Loop?

Apr 14, 2011

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)

Slackware :: EQ Overflowing Server Is Probably Stuck In An Infinite Loop?

Oct 28, 2010

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

Ubuntu :: Login Cycle Loop After Username / Password Entered

Aug 12, 2010

The login cycles- I already have a problem with mounting something connected with USB (long term minor annoyance, but everything works), but suddenly I cannot log in. When I put my username and password in, the screen flashes black for about half a second, then the login screen re-appears. If I put the wrong password in, I get an authentication error message (as expected) without turning black and then cycling again.

I have no problems going into terminal mode and logging in. I've tried all sorts of suggestions related to this problem- reinstalling ubuntu-desktop, apt-get clean, sudo startx, and the last indicates that x-windows is already running. I've found a couple more things to try, but I'm not too sure how well they'll work. It seems to be connected with x-windows, but I don't know what is causing it. Last night I had a big problem that required reinstalling nautilus (couldn't set up a connection to a remote server), and that problem was fixed- but this developed when I booted this morning.

General :: Loop Terminates / Quits After Single Cycle

Jul 14, 2011

I tried to find an answer to whatever is happening with my sh, tried a few approaches, but none is working the way I planned... the loop quits with exit 0, runs once, if I comment out 'ffmpeg' line, it runs N times as it should - ffmpeg does not error out other than 0.

Code:
find . | grep .mp3 | while read filename do
newfilename=`echo "$filename" | tr ".mp3" ".ogg"`
ffmpeg -i "$filename" -acodec libvorbis -ac 2 -aq 4 -y "$newfilename"
echo inside #4debug
done
echo outside

This sh runs once, echoes "inside" 'n "outside" once, exits with '0'... unless ffmpeg commented out. I also tried to feed the loop with: done < /tmp/fname.list. BTW, this works well - but I am very interested in the >while read< loop giving up.

Code:
for i in *.mp3; do ffmpeg -i "$i" -acodec libvorbis -ac 2 -aq 4 -y "$(basename "$i" .mp3).ogg"; done

Fedora :: Stuck In Infinite Loop On Login After Changing Wallpaper?

Aug 17, 2011

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).

Ubuntu :: Infinite Boot After Uninstalling Some Packages?

Oct 16, 2010

I was possibly overzealous in uninstalling packages using deborphan. I uninstalled various libraries and progams that I don't use (ppp, gimp, etc.), but I must have touched something useful, since the machine will no longer boot.

I thought this might cause a few problems, but expected to be able to recover, at least using the Recovery Mode. This isn't the case, sadly.

The main symptom is an infinite boot process, even using the recovery-mode boot. Things proceed as normal (grub screen, few lines of startup messages), but then a ton of text starts pouring onto the screen. It scrolls much too fast to read, and the Pause/Break key won't stop it. I do notice that there is a lot of talk about devices and udev, but can't make out more than that. The text doesn't obviously repeat, so I tried just waiting it out, but gave up after a couple hours.

Ubuntu :: Endless Boot Cycle With Xp In Grub2

Mar 23, 2010

I have recently been unable to boot into windows xp, which is on a drive separate from my linux installation. When I select the windows installation, the computer starts back at the bios screen and returns to grub endlessly. I am running an updated 9.10. The linux will boot fine; however the most recent kernel does not show up on the list of available options, which may indicate something. I have searched the forum and found nothing that helps. There are plenty of posts asking if you have stopped using windows altogether and other non tech related posts though.

The results of sudo fdisk -l are below:

Ubuntu :: Boot Into Single User Mode Or Escape Out Of This GDM / X11 Fail Cycle?

Jul 3, 2011

I installed Ubuntu 11.04 and it refuses to show me a boot menu so I can select single user mode. When it does boot, it continues to cycle as X11 fails, but will not let me change into any of the consoles via control+shift+1-7 or control C or any command. X11/GDM continues to cycle as I hear my video card keep spinning up and down. In every version prior, after 3-4 fails it would give you a shell and say, ok it failed. how to boot into single user mode or escape out of this GDM/X11 fail cycle?

If I nuke Kubuntu, will Grub still exist with my Ubuntu/XP entries to boot?

Ubuntu :: USB Boot Caught In Loop When Loading PXE?

Jan 22, 2011

I am having issues loading Ubuntu 10.10 from USB. I have a HP Compaq nx9110 laptop, p4 3.2 512ram etc with a dead hard drive. I would buy a new HDD but i cant really vouch spending $80Aus on a IDE 2.5 just to play with linux. Anyhow it seems to read the USB stick which was created following the directions on this site but when it attempts to load the Realtec LAN (i think) it seems to get stuck in a loop. I have attached a screen print of what i see, it hangs for a few seconds then starts over with the same writing. Anyone know what that means or how i can fix this so i can try 10.10?

Ubuntu :: ScanJet 6200c Causes Boot-Loop

Feb 16, 2011

I have a system which has been running 8.10 for two years (and am preparing to rebuild). Yesterday I thought to reboot it and am now stuck in a boot-loop getting the "not responding" x.xxxxxx error.

I made no changes prior to the reboot (just felt it was time) other than moving documents off the main drive onto a spare (preparing for the rebuild).

I have tried booting into several of the previous kernels and I ran memtest (flying colors). I keep getting the same error.

I have now built a 10.04 system for this machine. The old 8.10 drive seems to be in perfect order and I was able to pull various files from it.

I thought this would be the end of it but if I boot this new machine with my HP scanner attached via USB (any port) I get the boot-loop as in 8.10.

Again no changes were made to the 8.10 build prior to yesterday's reboot, and that scanner has been attached for more than two years (and working with fair reliability). I have had to alter its USB port or (inclusive) power-cycle it for Ubuntu to find it, but I had to do this when it was attached to an XP machine and so thought nothing of it.

Why has (presumably) the kernel driver suddenly crapped its pants?

Oh, and for the doubters I was able to boot into 10.04, open x-sane (which I prefer over Simple), locate the scanner (after power-cycling it), and scan an image. I just had to attach the scanner to the machine after the kernel loaded (at the login screen).

Ubuntu :: Change GRUB Boot Order: No /boot/grub/menu.lst File

Nov 29, 2010

i am trying to change the boot order on the GRUB menu so that the countdown automatically starts on an older kernel. From what i can see all the solutions on the web want me to edit the /boot/grub/menu.lst file. The problem is that i don't have one. Someone also mentioned that if i don't have a menu.lst file then i should look for the grub.conf file. I don't have on of those either. The closest thing in /boot/grub is grub.cfg but that looks nothing like the descriptions i have heard of /boot/grub/menu.lst file

Ubuntu :: Reboot Loop On Dual Boot Netbook?

Mar 10, 2010

I recently installed Netbook Remix(Karmic, I think) on my Samsung N130 netbook as a dual boot with Windows 7. It had been working fine, I'd had no problems switching OS and I had restarted my computer many times without issue.

Today, I was on Windows 7, set it to hibernate when I left the house as I sometimes do, and when I came back and turned my computer on, first it asked which system I wanted to load which it never does after hibernation. I selected Windows, and it took me to the Samsung Recovery Solution screen for some reason, and I closed that. It restarted the computer, and when it turned back on it said GRUB loading, and rebooted again, and keeps looping that whenever I turn it on.

I tried removing Ubuntu using GParted from a flash drive, but I'm still stuck in the loop, and it's gotten rather frustrating.
