This has been confusing me for a while. It usually takes about 4 or 5 times of hitting the power button for it to start up to the login screen. All it does is go to the Ubuntu splash screen and that's it. The colored dots don't change or anything. It just sits there. I ran the memory test to be sure it wasn't RAM and it ran fine.
I've been getting a random hard freeze, in both windows and linux, so I'm pretty sure it's not a software thing. I've run memory diagnostics in windows and it came out fine, I'm not sure what other diagnostics I can run. what tools can I run in linux that might help me further diagnose the problem? I haven't installed any new hardware, and I blasted the inside with some compressed air to err on the side of caution, but I still have problems. i'm running the latest ubuntu ver btw
I had installed Ubuntu Studio Natty from scratch onto a fresh partition, keeping Ubuntu Studio Maverick on another partition until I was sure Natty was working right. But whenever I tried using Natty the system would totally freeze, or so it seemed. Everything would freeze except the mouse pointer. Even the clock, which I have displaying seconds, would stop counting. I searched all over and there seemed to be little agreement about the cause of this, but a lot of people seemed to be experiencing it. It seemed to me however that there was a trend toward blaming new 3D features, and some tips suggested starting with 3D display features disabled; I forget now how to do that, but I do know that it didn't work for me.
After sort of giving up for a couple of months and going back to Maverick I had the idea to try installing (actually "activating") the Nvidia proprietary driver---and the problem seems to have been totally fixed. That's literally all I did, and for at least a few weeks, maybe a month or more, no freezes.
I should add that after a while the symptoms revealed that it wasn't necessarily that the computer was freezing, it was that it would rev up to maximum CPU usage and stay there, with a restart the only solution, until it would start again, seemingly at random, after several minutes to a half hour usually.
My problem is that my server randomly hangs. If I remember right it started after an kernel update (can't really remember if it was a kernel update specific, but I did install new updates before this problem occurred), and then I noticed my server was down one day, after that the problems/random freezes continued. And there are no pattern/interval between the freeze ups.
I think that all this started for about 3 weeks ago, so I've never had this problem with Ubuntu 10.04 before.
At first, I thought the source to my problem was an old IDE which I accidentally left in when installing Ubuntu at the first time, so GRUB was sitting on that one. So I backed up almost all of my data, reinstalled Ubuntu 10.04 (downloaded from the website) but this time without the old IDE drive. Everything seemed to work, had no crashes or freezes. I do have to mention that the same thing happend to the live CD before I removed the old IDE.
But now the fresh install of Ubuntu seems to hang too. And the worst part of this is that I can't really do anything about it to test or look up what may cause the problem, as I have to access it remotely because I'm on vacation right now (I'll have to get my friend over there and restart it).
When the computer hangs it comes inaccessible from the network, can't even see that it is up in my router. But I do know it is running, else it would have been shut off and then started up again and work.
Before I re-installed it, this problem could be reproduced by surfing the web and watching flash videos in either chromium or Firefox.
And I do know it sounds silly to run a server with the desktop edition installed, but if I don't have any other computer accessible, I use my server instead.
I just installed Fedora 12. Now i've seen a few other threads but they seem to have all the conclusion that its the Nvidia drivers at fault. Well i have an ATI Mobility Radeon 3400 series. I can login, and navigate for a little bit, then it just randomly freezes. I've booted to both gnome and KDE, kde freezes almost immediately w/o letting me navigate much. Gnome takes a bit and then freezes on me. I managed to login once and go like 6 minutes then i thought it was worked out, rebooted and boom, froze up again. I can still move my mouse but can't click or use keyboard. Ctrl+Alt+Backspace doesn't work either .....
As this thread [URL]... reached over thousand posts, it's obvious that these freezes (which actually boils down to keyboard and mouse not being listened to by X server, so "not working") hit large numbers of Ubuntu users. As that thread is already very large and hard to read I'd like to advance a hypothesis here : This problem occurs only on multi-core CPUs.
I've installed 10.04 on two machines: and old box with a Duron and new one with quad core. The old box runs just fine with 10.04. The new one - you know Has anyone exeprienced this problem on a single core machine?
I am a Ubuntu user since a few years (Breezy Badger was my first) now but I still don't know much about computers or commands so please bear with me. I used 10.04 on my HP pavillion PC of two years old without any problems. Now I upgraded to 10.10 with update manager. And it boots fine, but whatever I do, after aprox. 10 minutes everything just freezes. And I don't remember the magic phrase for soft reset, so I hit the power button.
I have searched the forums and could not find a satisfactory answer to my problem. I found this thread [URL] but have no idea how to do what's requested. Could anyone please tell me what to do?I know how to open a terminal, and type a command or two but that's basically it.
I seem to be having a problem on the new Kernel (2.6.35-23) with the system randomly freezing.
I have installed a number of things in recent days leading up to this problem, but when i boot with the old kernel i don't seem to have any issues. From this i am guessing its the new kernel.
The freezing seems (although i am not sure) to be worse when Rhythmbox is running. When it happens everything freezes, the playing song skips, replaying the same one second of music over and over. All the hotkeys stop and the mouse cursor stops responding.
I have seen people talking about system logs to look at system crashes but i don't know how to show those. I also doubt my ability to interpret them.
I'm running Fedora 12 with GNOME on an old Toshiba Satellite A15. From time to time I get a system freeze, where everything stops working besides the touch pad (I can move the cursor, just can't click on anything). When I boot up, I see an error message that it skips past before I can read anything, although I have spotted the snippets 'pci' 'error' and what appears to be the 0x at the start of a memory address. When I try and shut down the system (going either by command line or the System->Shut Down part), I get to the part where it says "Unmounting filesystems..." and then it stops right there. When I boot it back up, I get an error that says "A crash in package kernel has been detected."
The same happens when I boot up after the hard freeze. It seems more frequent when I have a heavy load on system memory, but for the most part it seems random. I've seen it crash after 5 minutes with only Pidgin or gedit open, I've seen it run for weeks with over 100 Firefox tabs, Pidgin, 3 documents, and GIMP running, but it seems more likely in the second scenario. It also seems to have a chance of freezing again within 5 minutes of rebooting (even if I don't touch anything after login). I ran Fedora 8 and Fedora 10 on this computer just fine, with most of the same system settings (copied my /home folder for each upgrade). I have a dual-boot system (XP/Fedora), with a third partition for data and a 200MB partition for the boot loader. The partition with Fedora is encrypted, and the crashing while trying to unmount the filesystem implies to me that might be the problem, but whatever it is, it wasn't in Fedora 8 or 10 (at least as far as I could tell).
It seems that my Ubuntu 10.04 (clean install) to randomly freeze / hang (mouse/keyboard unresponsive, only a hard reboot is available as option) but with no garbled screens/windows/etc. There's no pattern why or any application that could be responsible. It could happen ten minutes after it is started or after 2 days but at some point and suddenly the system will become totally unresponsive, freeze and hang up. I used the same PC with Karmic Koala and releases before that (sometimes on for days) with no such problem so it shouldn't be a hardware problem.
I thoroughly check system logs after the hard reboot (System > Administation > Log File Viewer) and there's no entry around the time of each freeze / hang to pinpoint me to something.
The only thing that is certain is that the following errors / warnings always appear in .xsession-errors file:
Here is also some info about my system: M/B: ASUS P4R800-V DELUXE CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz RAM: 1GB Graphics: ATI Radeon 9100 IGP
I am running Ubuntu 10.04, randomly while working in gnome with no particular application I get a freeze periodically. Neither the mouse or the keyboard will respond. I am running it on a lenovo Z61m laptop. I have had previous experience with Posix systems but I am a recent migrant from XP as my primary operating system. I never had such an issue with this computer which leads me to believe that it is not a hardware issue.
Running updated 11.04 on a older Dell Precision 360n. Been having random system freezes for the past month that requires a hard restart (REISUB doesn't work) each time. Sometimes the caps lock and scroll lock LEDs blink, other times not. sometimes it happens during boot, other times during normal usage. There hasn't been anything in any of the logs (except once, which I'll post below). This happened running 10.04 and 10.10 as well. I've run PC-check a few times and all hardware diagnostics have passed. Until today, i've been able to boot and run Trinity Rescue Kit 3.4 to mount the disk and examine the logs (and do backups), but now TRK won't boot and spews kernel panics when loading.
I downloaded and burnt the Kubuntu 10.04 release to a CD. I tried to install it. First time, couldn't find the disks and eventually it froze. Ok, second try, when it's contacting the "time server" (or whatever) another freeze, but this time I notice everything is running fine and then get a nice little image with the current time (increasing seconds and all). Third attemp, clicked the "update this installer" and it went fine. "Yay!" I thought. Well, a few minutes in my beautiful 10.04 system and again, another freeze. Hit the power button and to my surprise a "Shutdown" dialog shows up with a countdown. After 30 seconds it logs out and mouse is working again. I log back in and come here to write this long post, and as I was writing the title "Random mouse/ke..." guess what? Yeah, it froze again. And the little bar that goes after the writing continued happily blinking. Hit the power button but this time mouse and keyboard were still frozen in the login screen.
Short version: mouse and keyboard randomly freeze while the rest of the system apparently work fine.
I am using Ubuntu Lucid Lynx 10.04 (64 bits) in my Asus U30JC laptop (Core i3 M350, intel 4500MHD + nvidia 310M with nvidia Optimus, 4GB RAM). I am content with Lucid and I don't want to upgrade to 10.10 for now. However I read that the new 2.6.36 kernel has some good improvements, such as improving system interactivity while intensive I/O (such as copying large files), and improved energy management for i3/i5 processors (which I hope translates into more battery time, which is a problem of Ubuntu vs Win7 in my laptop).
I discovered I had 2 options: compile the kernel myself, or use the Ubuntu Kernel PPA (maintained by the Ubuntu Kernel Team). I decided to use the PPA, so I added it to my software sources and installed the generic"linux-lts-backport-natty" kernel (2.6.36-1).
Package installation went fine, and after reboot, I could log in to the desktop no problem. Everything seemed fine, but after a few minutes, the system freezes completely: mouse did not move, none of the indicators moved, even Ctrl + Alt + F1 did not work.Where is the log file where there might be a message related to the freeze? Do you think that the kernel developers would try to fix a bug that probably only affects people running the 2.6.36-1 kernel on a distribution that was not built around it?
I'll start at the beginning. The problem i am about to describe occured in ubuntu 9.10 for the first time (https://bugs.launchpad.net/ubuntu/+bug/480850) and is ironically partly responsible for my switching to debian. which i don't regret, but it seems i can't run from the bug any longer because now it's in squeeze, so i want to fix it or make a proper bug report:
Steps to Reproduce: 1: Suspend Laptop to RAM 2: Resume from Suspend 3: Wait and see, preferably monitoring top: At some random time, ranging from immediately (black screen after resume) to several hours later, the system will become unresponsive. Switching to tty1 or Alt+Print+K does not work, Alt+Print+REISUB does work. Each freeze is anticipated by a random process (this time it was mandb, was installing something) hogging 100% of CPU, then the System becomes gradually unresponsive within a minute or so (panel, metacity, finally mouse cursor freezes too). Alternatively, in case of a black screen immediately upon resume, Alt+Print+K works (EDIT: or not), and the system remains usable. Additionally, i don't know if this is related, i noticed one process using 9999% of CPU for a second according to top, just thought i'd mention it. This bug constitutes a regression, suspend does work flawlessly on this Laptop in Lenny.
The above is how it presented itself at the beginning on a fresh squeeze install, however, after two days of trying, i additionally get kerneloops messages i did not get before (again, after at least one suspend to ram) and after that the system becomes generally unstable (random applications won't properly open or terminate, including nautilus, evolution, iceweasel). Can this be due to secondary damage from the freezes and alt+print+reisubbing repeatedly?
The good news is, apart from this probably already damaged squeeze install, i have another one on one of my playground partitons, where i avoided suspend so far, so i can still try things out there. (it's kde, but i don't think it's related to the desktop environment).
Basically when I add more than a single 2gb RAM module, my computer starts randomly crashing every half hour or so, the screen freezes with no response. I have tested the RAM with memtest 86+, it only happens when there is more than one module. The system is openSuse 11.2 64bit and it had a single 2gb RAM module when I first installed it, and removing all but this seemingly fixes the issue. The following is the error message I get when the system crashes, It seems to continue messaging after the initial visual lockup.
I don't know what the problem is, but from searching the web it could be a number of problems, the memory is not being allocated correctly or it maybe there's some conflict no between my ATI HD card/driver (latest driver from ATI repo).
Karmic - When I start up and log in, a window for KDE Desktop Sharing Invitation automatically pops up.
Closing it doesn't prevent it from popping up on next startup.
There doesn't appear to be any option to "Don't show on startup."
When I go to System -> System Settings -> Advanced -> Autostart, it does not appear under Desktop File. The only thing that appears under "Script File" is gtk-2-engines-qtcurve.rc.sh gtk2engines... which does not appear to be the issue.
I'm guessing there's a shell command that will give me a more in-depth look at what should and should not run upon startup? Would really like to startup with a clean screen!
Running Lucid 10.04 in place of XP on my old Packard Bell Imedia has been good apart from the random freeze-ups that often prevent booting or stall the shutdown process. Today I think I solved it!? It appears that my wireless PCI adapter (ZyXel G-302 v3) was causing the problem. Ubuntu had installed a default driver which seemed to work OK; but I thought I'd try installing the Windows XP driver from my original ZyXel install disk as an experiment. I used ndiswrapper, got the XP driver installed and my freeze-ups have gone (touch wood).
I have been using vim for years without problem but today I have met one weird scenario which I can't solve it after troubleshoot for the whole day and google around. This happen to my 2 machine at home which both installed with Slackware 13.1..I just got my laptop done setup with Slackware 13.1 and I ssh from my laptop to my desktop that have vim installed. I use one of my laptop virtual console to do the ssh login to that desktop.
And using vim in that laptop virtual console and Konsole itself, all works fine. The problem only occur when I ssh into the desktop using a virtual console.It seems like if I supply the vim specifically a .vimrc, it will work fine. It seems like it's taking forever to find the .vimrc file. But if I remove that .vimrc, it will also freeze. If I create a new user in that desktop and ssh again and then do vim, it will also freeze.Any one face this strange problem before ? I know I can still use Konsole to ssh and do vim, but I wish to solve this and since vim is been there for so long, I think this problem will most likely faced by someone before.
I'm running a Linux Box on a Seagate Free Agent Dockstar, very limited machine but more than able to do what I need, which is true most of the times. I have the operating system on a flash drive and use an external USB 2 "classic magnetic" Western Digital 1,5TB hard disk for massive storage. Not seldom it happens that the wait for IO % suddenly goes up to almost 100% and the system is on its knees, to the point that is very difficult to even ssh in it; a typical 'iostat -x' in those situations gives output like:
I really think that the drive has hardware issues; I noticed that when it is busy 100% without load it makes a repetitive noise which reminds me of the old day Amiga floppy disks - they made a similar noise like they were going around without a goal. For this reasons the suggestion to move /var and /tmp to the magnetic disk only worsened the situation. I guess the only way to solve this is to buy a new hard drive and backup valuable data ASAP.
My F-14 x64 bootup stalls with this message: "K10 temp ... unreliable CPU thermal sensor: monitoring disabled". I'm unable to find an explanation/basis for this message. I can boot from CD#1 and chroot onto the disk - near as I can tell, all the data is there. Might this be the result of a corrupt boot up sequence file and, if so, which one(s)?
I recently tried to upgrade from 2.6.23 to 2.6.32 but kept on getting VFS errors. I had overwritten the old 2.6.23 kernel so there was no going back. Luckily,I had the 2.4.31 kernel still in the /boot directory.
Anyway, I finally got some time to figure out the VFS issues and I managed to solve the VFS kernel panics. It was probably a forgotten configuration setting during the make menuconfig. Now it boots up only to hang right after the "Using /etc/random-seed to initialize /dev/urandom".
Looking at the rc.S script, the next section does the dd if=/dev/urandom of=/etc/random-seed count=1 ...
I know for a fact that it isn't that line that hangs the system. I commented out that line and it still hangs.
Strange thing is that I can boot up 2.4.31 with no problem; but with 2.6.x, I get a hang-up. I did a google and came up with something about rc.udev.new, which I don't have.
Can someone point out to me what is executed right after/etc/rc.d/rc.S? Or maybe point out where it might be hanging? (To be honest, it's either a hang up or a process that's taking an extraordinary long time to run.)
just built a computer and wanted to try out some linux.
First off I burned the Fedora 10 x86_64 disk image (using disk utility on my mac at 4x speed then verified it) to a dvd. I start the install. "x startup fails to load, falling back to text mode" comes up. I use the text install then. It gets to the actual installation of the different packages then a black screen shows up with white text that's highlighted red (sometimes it's blue). It then freezes and I reboot. Sometimes it freezes at different points and with different messages, but the description above is what happens most often.
I try writing it at 1x speed and verifying. same thing.I try the Live CD. It freezes.Then I tried Fedora 9. same thing.
Next I go to Ubuntu 8.10.I try the regular install, but the orange loading bar freezes.I try the Live CD-like install. It runs!...but when i go to install, when it gets to the partitioning part, it freezes and becomes unresponsive.
Each time it froze I let it sit for about 10 minutes, just to make sure it is in fact frozen. I've tried these installs numerous times.
I'm looking for a script that copies a random .jpg from a random folder in my ~/Pictures folder to my ~/temp folder with a standard filename. This file will then be displayed in Conky. I can fix the last part, but I cannot find a way to do the first part.
