Ubuntu :: 10.04 Zebra Stripe Crashes
May 9, 2010
After having installed Ubuntu several days after its release, I have enjoyed the OS entirely except for one issue: zebra stripe crashes. When my desktop (stats are in my signature) is left idle, occasionally it will begin flashing from the blank navy blue screen (the screen saver when no screen saver is set) to zebra stripes which can be seen at the top right corner of the screen. When I attempt to move the mouse or even attempt to do remotely anything, the stripes and blank screen continue flashing regardless. I end up having to terminate my session by holding down the power button. I have installed all updates to date. How can this be stopped?

So I have a Zebra S4M label printer that I have managed to get mostly working under CUPS. To make that work, I have the printer upgraded with the latest firmware, CUPS 1.4.1 with its AppArmor profile disabled and the Zebra EPL/ZPL ppd file that's floating about the internet loaded into cups. The printer is connected via USB to the computer, and is set up in cups using ZPL. The computer acts as a print server for other computers, and everything seems to work ok, with one exception. When the printer runs out of paper or runs out of ink ribbon, the printer stops and displays an error on screen, but CUPS never stops. It keeps taking jobs, sends them to the printer and reports that everything is A-OK. It appears at a certain point, the printer's memory gets full and then CUPS sort of hangs.
But it still doesn't display and errors or stop the quque, it just starts this weird behavior where it eats jobs or combines them into one giant job that it just sits on. What I need is for CUPS to know that the printer is out of paper or ribbon and pause the queue until the error status is clear. I know that this printer is communicating its status in some way, as when it's connected to a windows machine, the print queue stops when the paper runs out. How to get CUPS to recognize the printer status so that I'm not losing jobs? I've tried digging through the debug logs but there doesn't seems to be much help there. I do notice that from time to time CUPS says it's discarding "unused printer status changed" and "unused job progress" events but other than that, nothing I see of interest.

Making the move to Ubuntu entirely but I want to get my 5TB raid function.
I can't seem to get it to recognize.
fdisk -l:
Code:
It works under windows? ( Its GPT I think btw)
Else I can re-partition and format it (its all backed up) but I want to be able to read the raid under windows as well...

I am new to Linux but have installed debian using the 'net method. The computer, in general, works fine. I have a USB keyboard which works OK and a Magnetic Stripe Reader which the OS thinks is another keyboard. If I open a terminal then swipe a credit card the data are transfered to the terminal screen at the cursor which I do not want.
How do I prevent the OS from grabbing the MSR? I want to use a program to address it as "/dev/hiddev0" or similar for read and write. I have tried "blacklist hiddev0" in /etc/modprobe.d/blacklist.conf but to no avail.Regarding these forums, I, for the life of me, cannot understand why a search for USB turns up empty when I can see the term in several titles on the first page of topics.

I am in one of those terrible situations...My motherboard died and I am left with a nvidia nforce raid stripe set that I need to get data off. I guess I should have setup that backup regime. Some search results have suggested that dmraid may be my white knight. I have pulled the data off each of the disks (3 of them) into image files (using ddrescue) and created loop devices (/dev/loop[1-3], using losetup).
I am running 32bit ubuntu 9.10 btw. When I do a "dmraid -ay" it tells me it found a raid set but has not activated it. When I do a "dmraid -r" it tells me I have a raid5 array on one of my /dev/sd? devices. dmraid seems to be ignoring my loop devices . Does anyone know if dmraid actually works with loop devices? If it does is there a way for me to point it directly at the devices and get it to do its auto-magic?

After upgrading to 10.04, Thunderbird crashes every 20 minutes or so. No mozilla crash reporter pops up... it just dies. No idea why. I filed a bug, but nothing seems to be happening with it. I find it hard to believe I'm the only one experience this level of instability.

I have a weird problem. Sometimes Ubuntu freezes when I'm booting up, sometimes not. I would say 2 out of 3 times it crashes, all other times it goes fine. I alway get past the GRUB bootscreen, then it starts loading. Towards the end or so, all of a sudden all disk activity stops and the screen hangs. Ctrl+C, Ctrl+Z, Escape, whatever buttons I press, it doesn't do anything.
I removed the "quiet" and "splash" boot options in GRUB so I could see in detail what is loading, but this doesn't make any more sense then before. The lines of text are always a bit different every time it happens so I can't really pinpoint when it goes wrong. Anyway, I don't see anything wrong with the output on my screen, I guess the real problem is not displayed.
I also tried booting into recovery mode. Also here this is strange. Sometimes I make it to the recovery screen with the options (resume, clean, netroot, ...), sometimes it crashes before that. When I get the recovery screen I choose "resume", this usually works and then I use "startx" to go into graphical mode. However, at other times, when I choose "resume" it freezes even before I get a login prompt.
So please guys, tell me, what is the problem here? How do I find out where I should start looking. Ubuntu sometimes freezes and when it does it doesn't alway happen at the same place as before. I know only 1 thing for certain, once I'm fully booted I don't have any problems whatsoever, everything seems to work flawlessly.
I am running a dual boot system with Ubuntu 10.10 and Windows7/XP. I am running kernel 2.6.35-24 (also tried 2.6.35-23, but no difference). I have an i5 CPU, so 64 bits. If you need any more information, just ask.

I am having following problem: Next to everytime, when I try to shut my pc down, KDE crashes, which is pretty annoying, because I like to download stuff over night and therefore I want to shut this pc down automatically. This is obviously not working when kde crashes everytime. I know that kde is not very stable, but is it really that bad? Is this a common issue?

I have some curious errors and crashes since yesterday. Firefox crashes without saying anything or just freezes. Thunderbird also crashed once without any reason, as far as I could discern.
Compiz is another candidate. Either it segfaults and sends me back to the GDM login screen or it crashes in another way, resulting in a flickering window with an unreadable error message (just an empty window with the nautilus icon in the menu bar, background image stays the same, Unity or any other compiz things are gone). I even had some real X segfaults mixed in.

Anywhere from 2 -> 6 times a day, my computer will freeze up. If any audio was playing, it will repeat the last few seconds over and over again.
I've been dealing with the problem for a couple of months now, with no solutions.
It can happen anytime, but it tends to happen on my screensaver about 50% of the time after I've locked my computer and during the early morning (12am onwards) when I have a full-screen video playing, but it's never done it at night in the same circumstances.
I am confused and just can't figure out the problem.
Computer info:
Mac Mini (2010) 2.4GHz
8GB RAM
Dual 24" Monitors @ 1920x1080.
Ubuntu 11.04 64-bit.

I am using Gnome Do 0.8.2, which I added using the PPA. It is great, although when I summon Do, and type a Ping.fm status, and press enter, Gnome Do crashes with this output:

I have conky on my desktop, and it works most of the time. The only times I've noticed problems are when I do large file transfers from my computer to an external HD.
What happens during large file transfers is that Conky crashes, and then I realize that my desktop is also "dead" (as in, I can't highlight anything. The icon for my external HD is gone, even though it is still mounted and accessible. Right-clicking doesn't do anything either.). I tried Ctrl+Alt+Backspace, but that didn't work either. I can log out and back in to get everything working again, but that's a bit of a pain.
I'm using the GNOME desktop on Ubuntu 9.10.

I have a program running on my server which I want to restart in the event that it ever crashes. Someone suggested "Watchdog" to me, but it appears to me that watchdog restarts the whole system, not the program. I couldn't find much documentation for it. Another suggestion I was given was crontab, except that I don't want to relaunch the program every 60 seconds, as it doesn't run on screen or anything, it forks itself into the background after launching it. Perhaps a bash script that would check to see if the program were running or not, and if it weren't, relaunch it? Not sure how to do that, I've never written bash. In any case, I just want to keep this program running full time.

When attempting to run pSX on Ubuntu 9.04 (and the 9.10 livecd), it crashes with a segfault. I -have- read [URL] and tried shutting down pulseaudio as recommended there. However:
Code:
$ sudo /etc/init.d/pulseaudio stop
* PulseAudio configured for per-user sessions
$ sudo killall pulseaudio
[Code]....
How do I get pSX working? I tried copying the psx.ini file from another machine because the thread says pSX works fine after you change the sound device used, but it still segfaults when I try running it.

I bought a new PC few months ago and tried Win7, no problems found. Then I installed Ubuntu 9.10 for x64 (I use Ubuntu since 6.06 but until PC upgrade I sticked to 8.10) and since then, every now and then bot win and buntu crash for no reason at random, often before loggin in. At firsth I tought it was some problems with the shared NTFS partition, so formatted it in FAT32 but this didn't helped. Now this's my fstab:
Code:
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier

My desktop has been running 64 bit 9.10 since an upgrade from 9.04 for 6 months with no problems.
Recently however, my system crashed for the first time. All windows closed and the system hung, attempting to open anything did not work. I would click on an icon or type Alt +F2 and nothing happened . Although my cairo-dock at the bottom of the screen was still running perfectly (including animations Etc.) albeit without any programs working. Trying to click on system manager gave me the message.
"Failed to execute child process 'gnome-system-manager' Input/Output Error"
Trying to reboot several times and selecting previous kernels brought me to a prompt where I was able to check all my important documents were still there, but do nothing else. Recovery mode also did not work.
Eventually I left the computer overnight and started it and Ubuntu loaded normally, then after around 15 minutes the system hung again with identical systems to the first time. Although this time Firefox greyed out first.
This has happened every time I try to boot the computer since and last time it gave me a screen saying Grub Read Error which after 3 reboots has finally allowed me to access my computer (from where I am typing with haste!).
Using lm-sensors I am sure there is not an over heating problem. Am I right in thinking this may be a problem with my hard drive? And if so what is my best course of action? Apologies for the length of this post and thanks for reading.

Ive been having some problems with a Compaq computer with Lubuntu installed. The problem is that Xorg crashes at random displaying a white distortion on the screen and it usually doesn't let me go to a terminal and i have to force a shutdown.
the same happened when I tried to install Ubuntu but worse. Another side effect is that lubuntu at boot up displays its logo in 16-bit colors and then goes to normal colors.
how can i diagnose the random crashes?
