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:

Ubuntu 10.10
Welcome to Ubuntu! * Documentation: [URL]...

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'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'm using debian etch and I've installed some automatic updates, after that some programs weren't running. So I restarted the pc. Now that the computer boot up normally but when it reaches the login screen it just emit a sound in the pc's speaker,he login screen flickers and is showed another login screen again and again and again (it's automatic). I can logon using the option single-user mode in the grub options, any idead on how can I fix it?
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)
there's 2 scripts that i want to run when my server start.I a bit new to linux, i found that i could use the script rc.local to run things at startup, although, what i want to run is 2 infinite loop, so the first loop run but not the second.
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).
I just installed 10.04, it boots fine and gets to the desktop. I can navigate with my keyboard fine. but when i move the mouse around. after a few minutes the screen goes black leaving just the cursor. I can move the cursor around the black screen. then the screen resets like i did an auto adjust on the monitor and the black screen with the cursor comes back up. once again I can move the mouse. Then It "refreshes" again. Stays in this loop until I restart it. But nothing changes. I have re-installed twice.
I am trying to do some shell programs. I tried some sites regarding the while loop, they give the structure as: Code: while [ n1 -lt 500 ] do echo $((n1+100)) done
But the below code also worked for me: Code: while ((n1 > 500)) do echo $((n1+100)) done By using (( )) I could use while, for. But the documentations didnt follow this way. I mainly use this for datastructure programming.
So I just upgrate my Ubunutn to 10.04 from 9.10 and it seems I have problem with graphic card. I added div file extracted from windows in the previous Ubuntu release and things were fine but now I have a black screen. This is the output of lspci
I have hundreds of files in one directory, is there a simple command or pipes of command I can use to append them together? I don't want to use any loops.
I am seeing the Vertical screen wrap problem (discussed in [URL]) on a 64-bit Athlon XP desktop with the Ubuntu version that I installed yesterday (10.04 LTS 32-bit).
Vertical screen wrap, with the mouse pointer offset by a few pixels to the north, taskbar partially visible .
The xserver video amd package version is, xserver-xorg-video-amd 2.11.8-4 and the geode package is, xserver-xorg-video-geode 2.11.8-4. Is it possible that the problem lies in the new geode package (and not the intel/amd driver) ?
I'm looking to get a shell script to loop through a number of directories and subdirectories,looking for files that contain a particular substring, and renaming the file by replacing the search string with a different substring. For example if you had a directory full of folders that contained digital photos (along with various other files which would need to remain unaffected), and the intent was to remove the "DSC_" prefix from several thousand files buried within. I've whipped up a rather long-winded solution that works well for this purpose but chokes on directory names with spaces. I am reasonably sure there's a 2 or 3-liner that would accomplish this exact same task.
function investigate { path=$1 for file in `ls $1` #for file in *
I have written the following script in my linux server to add users for LDAP database.But i can't able to run this.
The script is as following
#!/bin/bash echo "Mention the username which you want to convert LDIF format" read username if ["$username" -e "/ldiffile/passwd"]; then echo "Username already exists" else cat /etc/passwd | grep -i "$username" >> /ldiffile/passwd fi The output which i got : . ldapadd.sh Mention the username which you want to convert LDIF format yal2361 -bash: [yal2361: command not found
yesterday I updated my fedora 13 to fedora 14 (on laptop) and today i cannot log in on user. It just go blank for a sec and is back to login.
At text console (alt+ctr+f2/f3) i enter my username and pass it give this for a sec and resets (clean) console username: Name password: last used: [date] login: no shell permission denied
i used unetbootin (fedora 14 netinstall to update) and later i updated 1,5G before reboot (did update that fix, forgot its name tho :s)
I would most likely reinstall everything, but i have some work at laptop and as death-line is near, i would prefer to fix it if possible.
edited: i have installed F13 on unused space, is there a way for me to access and fix it? or at least get some files from there?
Not sure exactly how to describe it. I'll try to get a video for reference. The log-in screen comes up, I type in my password, hit enter, and the screen goes black and the log-in screen comes back up. I'm currently using a BackTrack installation (it sucks) and I'd like to go back to an OS that connects to the internet automatically, instead of me having to redo everything from a terminal upon startup
I have a real issue and need urgent help. I am stuck in a login loop and have looked in several threads in order to find a solution for my issue. I am relatively new to Ubuntu/Linux and do not really know my way around especially when it comes to command prompt. Thus I need someone with patience and who can guide me step by step in order to get to the bottom of the issue and to fix it.
The issue started all of a sudden, no particular reason. I only uninstalled evolution before and then rebooted. The shutting down process got stuck forever and I turn off the PC by holding the power button. Then I attempted to start, the PC boots to the login screen and I select my name and enter the correct password as usual. Then the screen changes for a split of a second to the back command screen and I can see the word crypto or so. Then the screen returns to the login screen and this loops.
Well, I am facing one issue:How can i read two files word by word at a time using any loop as i need word by word comparision in shell script?Please let me know pseudo code.
