Ubuntu :: Freezes Randomly, Flashing Keyboard Lights

Apr 5, 2011

I've been an Ubuntu user for a couple of years. I have a Sony Vaio VPCCW-2S1E laptop, with an Nvidia GT330M graphics card. I had worked with Karmic, Lucid and Maverick on this laptop without any problems, until recently, when I had to re-install Maverick.

Now my laptop keeps freezing entirely (no response whatsoever), with two keyboard lights blinking. This happens randomly: sometimes I'm doing something, other times the laptop's completely idle. Sometimes the screen display turns off on freezing, other times not.

Ubuntu :: 10.10 Freezes Randomly - Keyboard And Mouse Stop Responding

Feb 4, 2011

I have installed Ubuntu 10.10 on other machines before and have not experienced this problem. Occasionally, the system will lock up. They keyboard and mouse stop responding (my keyboard status lights no longer respond, but my optical mouse light is still on). I can ssh to the machine, and it seems to work as normal. I kill processes that are open on my desktop through ssh, (i.e., Firefox), and I notice when I switch back, I still have the same frozen image on my screen. I have looked at the following files to determine any issues with the GPU:

Debian :: Desktop Freezes Randomly And Does Not Respond To Keyboard Or Mouse

Feb 21, 2015

I am using Debian with a gnome desktop.

Code: Select alluname -a
Code: Select allLinux app-server 3.2.0-4-amd64 #1 SMP Debian 3.2.65-1+deb7u1 x86_64 GNU/Linux

My desktop sometimes freezes and does not respond to keyboard or mouse. I initially thought the CPU was overheating but it froze tonight when my CPU temperature was 32C and it has been up to 50C without freezing. I am beginning to think it is a software issue rather than a hardware issue but do not know. I looked at the pm-powersave.log and user.log but did not see anything suspicious.

Ubuntu Networking :: Ethernet - No Green Or Orange Lights Flashing At Back

Jun 22, 2010

i am getting really pissed off with my new core i5 system I have a gigabyte p55m-ud2 mobo ([URL]) which's got a Realtek 8111D lan chipset it connected to my router after fresh install of ubun10 and then i installed MacOSX 10.6.3 and it worked there too then i came back to ubuntu and it didn't work anymore, after several restarts it was still not working until i took out the power cord and mobo battery, and reinstalled them back later which caused ethernet to work once again. but then after a while it started not to work anymore, which usually got fixed with a reboot. now this time i had ethernet working and i just resumed from screensaver and it stopped agian

there are no green or orange lights flashing at the back and when i take the cable out and reinsert it nothing comes on but with a shutdown they do come on i don't have this problem on the other harddisk which now has win7 and i some times manually change the sata cable to boot into windows and use itunes and some other stuff to load music to my iphone. I dont like to have dualboot and i dont like to use win7 either i just have it on the other hard disk just in case

is the manual switching of hard disk causing this to happen? why do i get it working with restart/shutdown and when i am using it fine it just decides to stop working after a resume from screensaver or sometimes for other reasons and why does none of this happen on win7 is there a way to reconfigure the ethernet drivers or other stuff without a reboot i am thinking it might be a problem with network manager or a bug or something network manager is really crappy and i used to use wicd until that started to do funky things ( like not connecting to hidden networks, launchpad Bug #473817)

Ubuntu Multimedia :: Video Playback Freezes Screen Randomly While Sound & Keyboard Works

Feb 12, 2010

i'm using ubuntu since 8.04, and the current (9.10) is a fresh install on new hdd.the problem was the same each version (8.04, 8.10, 9.04, 9.10) - while i'm playing the video (no matter if i use mplayer [smplayer], gstreamer [totem] or adobe flash plugin [videos]) the playback freezes randomly for about 5-10 sec. during the freeze the movie is still played, i can hear the sound is ok. if i press [space] in smplayer it pauses the playback, so the responses for keyboard actions are ok. not for the mouse clicks however. i can still move the cursor around the screen but it seems the system is not aware of it (clicking on the "pause" button doesnt pause the movie). except the cursor, nothing changes on the screen (if the im [pidgin] window was blinking because of new message, it freezes etc etc).

is there any kind of log i could look into just to try figuring out the problem?it is impossible to watch any movie on my pc (currently i don't have tv)i installed windows on external hdd once and it played videos fine so i suppose it's not hardware problem .

Ubuntu :: 10.4 Freezing \ When Tried To Turn It On Some Of The Lights Came On And The Caps Lock And Num Lock Started Flashing?

Sep 14, 2010

I have a HP Pavilion dv4 that is 4 months old. Yesterday it suddenly seemed to restart then once I logged in it turned off. When I tried to turn it on some of the lights came on and the caps lock and num lock started flashing. Since then I have not been able to get it to work correctly.It once seemed to turn on but died again after the login window.I tried to use my live cd but the same thing happened. It started loading once, but then shut down again. Every other time it stayed dead minus the lights

OpenSUSE Install :: 11.1 Deactivates USB Keyboard - Lights Off

Feb 5, 2010

I used to work with a PS/2 keyboard. But one key of it has a malfunction. So I bought a new Cherry USB Keyboard. GRUB and the BIOS like it - no doubt, the keyboard itself is OK. But as soon as SUSE 11.1 takes control during boot, the lights of the keyboard are switched off, and the keyboard is deactivated. I even tried to re-install 11.1 from DVD with the USB keyboard plugged in alone - in vain. With the PS/2 keyboard I didn't ever had any such problems. I run a system with a Pentium III (Katmai) on an Intel RC440BX Motherboard.

OpenSUSE Hardware :: ATI Catalyst 9.12 -- X Blank Screen / Hard Lock Keyboard Lights Don't Toggle?

Dec 19, 2009

I installed the new 9.12 cat drivers in the usual way (init 3; rpm -e the old drivers; generate new rpm; rpm -i new drivers; init 5), but instead of starting like I expected, I got a blank screen and what appeared to be a hard lock (keyboard lights don't toggle, Ctrl + Alt + Backspace and Ctrl + Alt + F1 don't do anything).

I switched back to radeonhd, but I'd like to get the proprietary drivers working if possible.

The usual listings

[nathan@ebisu ~] lsmod | grep fgl
fglrx 2323096 0
[nathan@ebisu ~] modprobe -l | grep fgl
Looks like the driver loaded OK...
[nathan@ebisu ~] dmesg | grep fgl

Ubuntu :: PC Freezes Randomly 10.04 LTS

Jun 24, 2010

I just installed Ubuntu 10.04 LTS , and I liked it a lot, however I'm having a little trouble.

I've got an Intel Pentium 4 HT 3.2Ghz Processor and an Intel DGCC101 Motherboard with an Ati Xpress X200 chipset.

Ubuntu Installation :: 9.10 Freezes Randomly ?

Feb 11, 2010

I installed Ubuntu 9.10 on my older computer. Before the installation I used Windows Vista and Windows 7 and I decided to do a clean installation. When I ran Ubuntu from DVD it was perfectly healthy and no problems appeared. After the installation there became random freezes. The system freezes but mouse is still moving and can't do anything else than reboot.

From the other topics I read that it might be a problem with GPU drivers and I heard about this Envy program which might be able to install some drivers but don't know how to install that.

The computer is pretty old:

AMD Athlon 64 Processor 3200+
ASUS M2R-FVM (includes integrated ATI Radeon Xpress 1150)
1 GB of RAM
320GB Hard drive

And I couldn't find any Linux drivers for the graphic card from AMD's internet page.

Ubuntu :: 10.10 Freezes Up / Randomly Becomes Unresponsive

Dec 16, 2010

Two fresh installs of maverick meerkat on my laptop. Both times, problems started immediately. Playing media files, web browsing with a few tabs, or running bittorrnet freezes my humble system.

At some point or another during a lockup, the active programs running use up all of my CPU and a sizable chunk of RAM. Then after a few minutes, it stops and goes back to running normally for a bit. There seems to be no common element that sparks this behavior. Anything I do causes my computer to freeze for 2 minutes. It seems to be a common issue as well, and I've been unable to resolve this substantial problem. Is there some bugfix I am missing?

Hardware :: All 3 Keyboard LED's Flashing In Sequence At RedHat Login Screen

Apr 6, 2010

I did a quick search of the forums and noticed that 2 LED's flashing indicates some sort of kernel panic, but what about all three flashing, one at a time in sequence? I'm doing diskless booting of RedHat 5.1 on this machine but I'm hoping the problem isn't related to that, and just something simple. The OS loads, and I get to the login screen (not noticing anything about kernel panics during boot), but the keyboard doesn't work and the three lights flash. It's not a GUI login screen, so I don't know if the mouse would work.

Fedora :: F15 Freezes Randomly

Jul 8, 2011

I am using Fedora 15 64bit (GNOME 3). Everything is working fine and I'm really enjoying the new GNOME but when I use it for let's say a couple of hours, Gnome get's stuck.I'm able to move my mouse and music keeps on playing, but I can't click anything, drag windows or close a window.When I press ctrl+alt+F2 I can still enter a terminal. (by the way, how is it possible that the gnome-shell command uses 99.4-101% cpu without any noticeable lag on my system and a strong processor?)

Ubuntu :: System Freezes Randomly / Solution For This?

Jan 18, 2010

I recently re-installed ubuntu to fix my freezing problem, but with no success. disc has no errors. I cleaned the disc and the cd drive, the cd burner has a problem installing while the dvd drive does fine. The computer is a HP Visualize X-class workstation with dual 1000mhz pentium 3s, 2 gigs ecc ram and a ATI AllinWonder 9700 pro @ 2x agp(wish was higher), on-board sound. So my problems are:

1) It randomly freezes within 24 hours regardless of who is logged in or if effects are on or what the load is. mouse is frozen too, completely unresponsive even ctrl alt f1.

2) My sound is screwy. its supported by alsa but i have to play with the volume to get sound and lots of times there are audio errors, it sounds like its robo-trippin. I have tried the sound guide.

3) Desktop effects only work with the user that logs in first. If I try to activate them when I switch users it searches for drivers then says it cant be enabled. not a priority.

Window xp works okay but the graphics drivers are giving me problems so i decide to do a dual boot.

I think I am going to put in a different video card. maybe its not all there, it got hot once when the fan died, put in a replacement and it worked but i see lines moving down the screen when there are blacks.

Ubuntu :: Computer Consistently Randomly Freezes?

Apr 16, 2010

After 6 months or so I noticed my 9.10 install getting sluggish and it started to freeze habitually. I let it go until one day it consistently froze at the startup login screen. I installed 10.04 and the problem continued - After first installing it worked for about 6 hours without a crash, and then once again the problem developed into consistently freezing at the login screen.

I tested with some USB Live sessions and my live sessions never froze, even when active for a whole day. Remembering some I/O BAD SECTOR error messages from my 9.10 crash, I determined the error may be with the hard drive so I bought a new Hitachi SATA hdd (needed more GBs anyway). I installed 10.04 on the new hdd (H and after 6 hours again it crashed. When it crashes the screen freezes for about 3 seconds and then the graphics wildly split and it's just a jagged gray screen. However, as time has gone on over the past 2 days, the freezing situation has been better in that it hasn't come to the point where the computer consistently freezes on the login screen. The time before it freezes has varied from 10 minutes to 6 hours.

I think it's maybe a software issue with the nvidia drivers. I'm having trouble diagnosing this bug or providing information. I've included the output of lspci -vvv I have the nVidia GeForce Go 6100 graphics card

Debian :: Squeeze Randomly Freezes Up?

Apr 17, 2011

This usually took place when I switch back to console from X (Ctrl+Alt+F1).After I start typing in the console, the characters started showing up one by one slowly and more slowly. Finially the console was completely frozen before all the characters were able to show up. This took place in less than 5 seconds. And I couldn't switched back to X either.Sometimes this happened even when I didn't log into X

Ubuntu :: 10.04 64-bit Freezes Randomly With Weird Screen / Solution For This?

May 13, 2010

I installed 10.04 beta 2, but have all the updates to this point. Everything freezes randomly. I get a weird pattern across the screen and the mouse and keyboard stop working. From what i can tell, the hard drives just keep spinning at whatever speed they were spinning when the freeze occurred.

I haven't been able to reproduce it on purpose.
I was using an Nvidia 8400 GS and through some reading i thought it might be the nvidia drivers. I tried reinstalling the drivers and still froze randomly. I took out the video card but I realized I have an onboard nvidia chip (GeForce 6150SE nForce 430 rev a2). Drivers or not, it still freezes randomly.

Ubuntu :: Pidgin Randomly Hogging Resources / Freezes When Doing So

Feb 9, 2011

During random moments, pidgin will suddenly use up all of my processor, a large chunk of my ram (20% - 25% of 2 GB), and will become completely unresponsive. This lasts for maybe four or five minutes then returns to normal.Pidgin doesn't have any kind of terminal output when ran in a terminal, so I have no data to use that is of any help.

Ubuntu :: Freezes Completely Randomly, No Response Whatsoever?

Jul 11, 2011

Very annoying problem, just build a new PC, new 500GB HDD and:

AMD Processeur Phenom II X4 955 Black Edition 3.2 GHz - 125W
GSkill RipJawsX 4Go DDR3 C9 1600Mhz
Carte m�re socket AM3 - Chipset AMD 880G & SB710

Installed ubuntu 11.04, and now extremely randomely, it freezes completely, cannot get to a console, ie CTRL+ALT+F1, ALT+F2, the mouse do not even move. I have to turn it off and restart. It may not happen for a whole day as it can happen 2 or three times in a row. From what I have gathered, it only happens when I use the PC as I can't remember coming to the PC and finding it frozen. From searching the forum, some people seems to have problem because of the 4 cores of the phenom, but it was very vague.

How can I know better what is happening and how to fix it. I have so little time, I really would love to avoid re-isntalling the whole thing again, as it is properly setup at last.

General :: Re-installed Ubuntu And Now It Freezes Randomly With No Errors

Apr 22, 2010

This box was formerly running Ubuntu Server x64 9.04 on the same hardware and ran just fine. I have now turned it into a media center box running Ubuntu Desktop x64 9.10. Since this has been installed it freezes about once a day. When that happens I can't do anything with it, can't even SSH. Also, and current SSH sessions die and exit. I have checked every log under /var/log but I have not found the problem. There does not seem to crash after any certain amount of time, just after several hours of sitting idle.

Below are a few examples of the last entires in several logs. Note for the clocksource error I have already forced it to use different ones in my kernel options and rebooted but it still crashes, still with no errors to tell me what went wrong. I also know the rsyslog error is caused by a bug and would not cause the crash.

Debian :: Desktop Freezes Randomly Two Times

Feb 17, 2010

I have used debian in the past and I am pretty comfortable with it but I have been having an issue. My desktop has randomly frozen two times. All my applications are still running though. For example, I was still able to talk on skype with my friend. However, all I can do is move my mouse but I can not click on anything forcing me to restart. Here are some things that might be helpful:

-I was using compiz both times (I am assuming this might be why. however, I have used compiz on ubuntu and I have never had a problem)
-I use an ATI graphics card
-It froze the first time when I accidently tried to extract the skype install deb.
-It froze the second time when I pressed close in software sources
-Since I have installed debian, I have installed compiz, compiz effect packages, removed openoffice, installed opera, installed google chrome, installed flash, and installed skype.

Does anyone know why my desktop crashed?

Fedora :: System Freezes Randomly - How To Troubleshoot

Mar 26, 2010

I am running the Nvidia driver. My system freezes randomly. I've had to reboot my system over 5 times today alone. When it freezes, everything is frozen, even the second hand on the analogue clock. One more issue, and I'm not sure if it's related, my stupid screen goes black after 5 minutes of no typing or mouse movement. This never happended when I first installed it. The issue just started within the last 3 weeks. Kpackage Kit is hidden. I was using it to do my automatic updates. Now I just use yum. between the time I first installed Fedora 12 and now, something has happened to my build to cause these issues.

Ubuntu :: 10.10 Randomly Freezes \ Get Context Menus But The Options Within Dont Do Anything?

Nov 4, 2010

i could be doing anything and suddenly the entire gui will lock up. i can right click to get context menus but the options within dont do anything. i tried xkill with alt-f2: it activated the crosshair but when i clicked on something nothing happened.this started happening after i played minecraft (downloaded version) for an extended period of time (slow as dogcrap i might add). now it happens after a random time has passed no matter what im doing.

the only way to rectify the problem is to kill the Xorg server and restart it. the computer was still usable for a short period, but it'd crash eventually. after a reboot it's good for a longer amount of time before it crashes again.recent things i've done that might have an effect is i installed kde and then removed it again

Ubuntu Networking :: Windows Browsing To Samba 3.4 Shares Freezes Randomly

Oct 8, 2010

I have an Ubuntu Server 9.10 box running Samba 3.4.0. It has 4 shares, one of which is a CIFS connection to an XP machine, another of which is a password protected share. All the shares work fine and well. However, lately the client has called to say that "everything's hanging and freezing" when they browse the shares via Windows Explorer (approximately 30+ PCs on network, variety of XP, Vista and 7 OSes).

Not all users always experience the problem, and I remote in to test when I hear this via an XP machine, and today for the fist time I also experienced this problem - browsing literally sticks and hangs. No entries in PC's eventviewer. They are running on Netgear switches, all the same age, a couple of months old. A simple reboot and and everything's fine again for an indeterminable time, then I get another phonecall and an unhappy client on the end!

Debian :: 8.0 Jessie Freezes Randomly On Mid 2009 MacBook Pro?

May 14, 2015

I have installed Debian 8 Jessie on my mid 2009 (5.5?) macbook pro. My computer is dual booted with OS X. I installed / on a partition with 30GB space, /home with 40GB, and swap with 4GB. My computer states are: 4GB ram, Intel Core Two Duo CPU 8700 2.53 Ghz x2, Graphics Gallium 0.4 on NVAC. The system has been running great compared to any other distro I have tried, except for that it randomly freezes sometimes. I've been running it for 4 days now and it has locked up 4 times.

Twice waking from suspend, once when changing the desktop background photo, and once after a reboot. I've a little afraid of messing with NVIDIA drivers as I tried that with various other distros and every time I rebooted after using these drivers the system would never boot into GUI and crazy kernal panic would insue. This is the closest I have come to successfully running linux on my mac. If there are any logs or information I can provide to find a solution to the freezing that would be amazing, because I absolutely love this setup!

OpenSUSE :: 11.4 Freezes Randomly - Xorg Occupies 100 Percent CPU

Apr 12, 2011

My pc freezes when firefox is running not only to open a new tab but also to browse some pictures and flash video. The screen freezes, no Keyboard response. Only mouse pointer can be moved but it cannot execute any program. That means I can see the mouse pointer moves but it cannot click on any icon. I have to ssh from my laptop to my PC and kill firefox process but can't get any improvement. The screen is still freezing. Then I have no choice but to use root right to restart the pc. This system freezing has happens many times since the PC system was updated from openSUSE 11.3 to 11.4 one month ago.

It's really random and I don't know when it will happen next time. But when it happens then I have no choice but to restart computer again. I notice that every time when PC freezes, the Xorg occupies 100% cpu resource and as long as keeping this status. Even when the PC dose not freeze, I feel the mouse point does not moves so smoothly. It could stop for a very very short time in its moving. I did not find this moving problem when I was using openSUSE 11.3. I guess it may caused by the video card driver which may not installed appropriately on my openSUSE 11.4.

Using "lspci |grep VGA" I get the following video card information:
01:00.0 VGA compatible controller: nVidia Corporation GT218 [GeForce 210] (rev a2)
