Ubuntu 7.04 freezes

Asked by harshad on 2007-04-24

I installed Ubuntu 7.04 with no issues or error messages.
The new desktop features are really gr8.. and I am enjoying it.

However, sometimes Ubuntu simply freezes, with no error message.
Keyboard does not respond, I can move the mouse around, but cannot click or select.
It simply freezes.. hard boot is the only solution. It again comes up fine with no error message.

Is it related to my graphics card (I am using Dell Inspiron 6000 laptop - ATI Graphics Card), I have enabled desktop effects and even installed Beryl.
Any place where I can check the logs to know the problem.

thanks,
Harshad

I would disable beryl/desktop effects and use the computer for a while to see if it still freezes.

I installed Ubuntu 7.04 too, with no issues on two same computers.

On the first computer Ubuntu freezes after a few minutes, or if i don't login after 5 minutes gdm freeze (Keyboard and mouse doesn't respond)
ctrl + f1 don't work
On the second computer Ubuntu freezes after a few minutes. Again the only thing I can do is reboot.

I have reinstalled Edgy Eft with dualboot edgy/feisty and all work fine in edgy but in feisty nothing change.

I don't use compiz or beryl, but I have an ATI radeon graphic card

thanks
Doud

Hi Alan as suggested by you, I disabled beryl/desktop effects and I did not face this issue.
I would monitor it for a few days.

I there any known bug in deskto effects ?

Also want to know, if I face any issue with the OS, what things I should check (I am new to Linux).

harshad (h-joglekar) said : #4

I still freezes, this happened thrice in a period of 2 hours. This is really a big problem.
Please suggest what I need to do.

Cesare Tirabassi (norsetto) said : #5

Any relationship with Firefox?

harshad (h-joglekar) said : #6

Not very sure, but this happens more when switching between internet pages.

Cesare Tirabassi (norsetto) said : #7

Try not using firefox (even minimised or in the background) and see if it freezes again.
If it is firefox it could be related to bug #107093.
Another similar behaviour is reported in bug #109740.

If you want to avoid the hard reboot try with the following key combinations for a "graceful" restart:

Alt-Sys-r
Alt-Sys-s
Alt-Sys-e
Alt-Sys-k
Alt-Sys-i
Alt-Sys-u
Alt-Sys-b

harshad (h-joglekar) said : #8

I still freezes without firefox running, there is no fixed patter of OS freeze, i can hang any time.........

Massimo Forti (slackwarelife) said : #9

harshad which kind of ati card have you ??? To know it in a terminal do "lspci" and post the rsult.
Have you enabled the fgrls modules using the restrict-modules-manager in Ubuntu ???
Can you post your /etc/X11/xorg.conf too ???

Thanks

harshad (h-joglekar) said : #10

Hi Massimo,

I have mailed you the files on <email address hidden>

Have you enabled the fgrls modules using the restrict-modules-manager in Ubuntu -- could not get this please elaborate...

Although I have wireless network card, but I connect to internet using wired network.
Is this issue related to internet connection?

One more strange thing, If I maximize a window and then try to minimize, this does not work. The window border becomes opaque and will not minimize.
If I try to close a maximized window, a window in background closes.
I installed alltray then tried to click on the app window as in the help, but this did not work and I lost display, again had to hard boot.

Please let me know if you need more info.

thanks,

Massimo Forti (slackwarelife) said : #11

The problem probably is about a bad xorg configuration. In Section "Monitor" of your xorg.conf file you can put a line like this:

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier "Monitor0" #put here your identifier name
    VendorName "Unknown"
    ModelName "LG L1910P"
    HorizSync 30.0 - 71.0
    VertRefresh 56.0 - 75.0
    Option "DPMS"
EndSection

This is mine. You must change the model name and HorizSync + VertRefresh with your data.

thanks

One more strange behaviour: The date-clock and the logoff, switch user, etc. button have moved to top center of the bar. The battery, the network display to the right corner.

harshad (h-joglekar) said : #13

I have put this, please correct if wrong

I haven't worked much after the change, once I got a display error, still would like to monitor.
I have a dell laptop, monitor details are shown as "Default Monitor" (I checked this in Windows as well)

I played with the panel icons once and since then the button positions are disturbed. How do I set them back to default ?

Thanks,
Harshad

it still freezes :(

Hi,

I just want to add that I have the same problem on a Dell M90 laptop. Everything works fine but suddenly the screen starts flickering for a brief period of time and than the network dies and all terminals get the "Uhhuh"-message. A few moments later the computer freezes. I've tried various things:
* with and without Beryl / desktop effects
* disabling nmi watchdog + blacklist video capture driver (I read that this fixes some freezes)

The problem seems very erratic. Sometimes I can work for hours and don't have any crash and sometimes the crash happens several times during an hour.

cheers,
Kristofer

tsella (tsella) said : #18

hi,

this is very frustrating - being a fresh mover to linux on desktop (newbie to linux desktop, not linux).

i have this issue as well on my lg f1 laptop.

does not happen with kubuntu, or installing kubuntu-desktop on a ubuntu (without changing the desktop manager).

completly erratic - i found some thread saying it was ff, but it happens regardless (although, it would seem less often).

no beryl.

Andrey Vul (andrey-vul) said : #19

Same here: Problem is probably Beryl as both KDE and Gnome require REISUB reboots after using Beryl for a short while.

I don't agree that this problem is strictly related to Beryl. I can freezes anyway although not as frequently. The last freeze was today, it lasted for about 15 seconds. I started to.. heh... hit my keys in random order, and suddenly the system was back again. :"-)

There were no console message this time. But this could be because I disable the NMI watch dog?

AlexV (aevasqueze) said : #21

This morning I installed today's update. The update had hal layer package plus other 4 or five packages. I have not had a freeze for over 4 hours. Before this update the freeze was within 5 to 10 minutes consistently.

richard7890 (hatter) said : #22

SYSTEM FREEZES - Ubuntu Feisty Fawn.

I have similar issues.

I was using Kubuntu. The freeze would start with the mouse slowing down for a few seconds then complete freeze. no k/b no mouse. only a hard reset would fix.

At first i suspected Kubuntu so I removed it and went back to gnome
then I suspected RAM, changed RAM still freeze.
I then removed beryl and compiz. Stilll Freeze.
Next I changed the entire computer suspecting Motherboard - Still Freeze.

The last thing that happened as per the other posts is syslog is being written to :

kernel: [20792.740975] code 00 00 8d bc 27 00 00 00 00 fa c3 8d b4 26 00 00 00 00 8d bc 27 00 00 00 00 fb c3 8d b4 26 00 00 00 00 8d bc 27 00 00 00 00 fb f4 <c3> 8d b6 00 00 00 00 8d bc 27 00 00 00 00 f4 c3 8d b4 26 00 00

kernel: Uhhuh. NMI received for unkown reason on CPU 0.

kernel: [20794.725993] Do you have a strange power saving mode enabled ?

kernel: [20794.725995] Dazed and confused, but trying to continue

One thing I think has been common is GAIM has been running.

The time between freezess is completely random, from hours to days.

Lets get this sorted out, if anyone wants me to try anything else please email me and let me know.

I installed Ubuntu 7.04 Feisty in my laptop. It is a Toshiba P35-S6292. Its video card is an ATI Radeon 9100.

I can use the computer for a while before it freezes. Some times 30min, sometimes less,
some times more. The impression is that using some programs (firefox, azureus) it freezes
more rapid. But none of the programs is the problem once it freezed the same way in a session
where none of these programs were opened.

My feeling is that the problem is at the ATI card driver fgrlx which I installed through the Restricted
Drivers Manager just after installing a fresh Feisty Ubuntu.

When it freezes the ctrl+alt+Fn terminals also freezes. At the moment just before the toal freezing
we feel the computer not responding to some gestures. Once a terminal freezed but the system did
not freeze at all. I did not install Beryl neither compiz.

This night I will change my xorg.conf to the vesa driver and see if the system will be freezed at
morning. With the fgrlx driver it would certainly freeze with this time. Tomorrow I send this test
result.

Please have a look if your system is affected by bug #86234 'swap partitions
each mounted twice', https://bugs.launchpad.net/bugs/86234

For this open a terminal and start:
 sudo swapon -s

If you see the same swap partition mounted under /dev/ and /dev/mapper you are
affected by this bug.

to solve this bug you have to run:
 sudo swapoff -a
 sudo swapon -a
after each reboot.

It will be good to confirm this bug, just follow the link above and confirm
the bug please.

regards,
thomas

lauro (lauro-lins) said : #25

the result of the test I said before

(...This night I will change my xorg.conf to the vesa driver and see if the system will be freezed at
morning. With the fgrlx driver it would certainly freeze with this time. Tomorrow I send this test
result...)

resulted in: the system did NOT crash or freeze. I left it doing some operations: downloading a file in
azureus with firefox and terminals opened, and it did not crash. I am still in the same session and everything
is perfect.

conclusion: this test strengthens my idea that it is the fgrlx driver that makes the system
freeze.

as I said before I just installed the fgrlx version suggested just after the Feisty Installation
in the Restricted Drivers Manager.

lauro

P.S. Thomas, thanks for the suggestion. I ran swapon -s to see if I had the problem you said
but I don't think I have it once the result was:

   lauro@aifos:~$ sudo swapon --s
   Filename Type Size Used Priority
   /dev/hda5 partition 1028120 0 -1
   lauro@aifos:~$

MHayes (hayes-mark) said : #26

I am encountering random freezes as well. At first I thought it might have been firefox or Beryl + XGL (ATI Radeom X1600) but after disabling both and using the default vesa driver the freezes still occur. When I first installed Feisty a few weeks ago the freezes were occurring within an hour of first boot. I added noapic to my grub configuration which made things better (would only freeze every few days), here's my grub config file:

title Ubuntu, kernel 2.6.20-15-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.20-15-generic root=UUID=ef8e4547-dcdd-4551-a7f4-fbc0162af1a8 ro quiet splash noapic

I also have a Radeon Mobility 9100...but am extremely ignorant as to what most of your are talking about. Might someone tell me what Lauro did so that I can fix my freezing issue also...this is getting really OLD...fast! It's like every 15 since my new install!

jasampler (jasampler) said : #28

Hi, my Ubuntu does the same thing as the first user said. I wrote this in the ubuntu forums before, in the hardware subforum, with no answer. I have a nVidia graphics card.

I chose the title "Frequent temporary freezes cause disk-related messages" for the post because I found that the logs were showing some messages after the freeze. I write here the complete post I wrote in the forums:

Hi, I recently purchased a PC with Ubuntu 7.04 pre-installed, from a local vendor. Then I burned a Desktop Ubuntu CD and reinstalled it. Both installations suffer the same problem:

The system freezes for some seconds very often, without repainting the windows and not responding to clicks, and after that everything runs again. Sometimes applications disappear after that time, even the GNOME panel. I don't have acceleration enabled or other configurations different from default.

I executed tail -f /var/log/messages to see what it says when system freezes, just if it could serve for figuring out what's happening, and this is the result (I replaced the name of the machine, "equipo-de-luis" with an "e" for brevity):

After a freeze, it prints:

May 27 05:38:14 e kernel: [ 1278.118238] res 40/00:18:27:ea:d9/00:00:00:00:00/e9 Emask 0x4 (timeout)

Then the system is responsive again. Here is another longer example following the last one:

I hope someone could help me telling me what to do with this.
Thank you very much.

Sorry, my problem is not exactly like those ones, since I can wait some seconds (or more) and then (sometimes) everything is restored. I also think that my problem is not related to the graphics card. I can give more information if you need. Thank you very much for your help.

Hi again,

My freezing problems stopped after the HAL-update to the feisty distribution a few weeks ago, as reported by AlexV. If you haven't yet had this upgrade this might solve your problems with random freezes.

Hi all,

I was having the same problem as stated above (Ubuntu 7.04 randomly freezes, keybord not responding, mouse still moving but else useless). After some surfing the web I found a solution to my problem. All I had to do was to disable the "Cool n' Quiet" feature in my Bios. Since then my system is stable. It would seem that my problem was related to the following bug report:
<https://bugs.launchpad.net/ubuntu/+source/linux-restricted-modules-2.6.20/+bug/109643/comments/9>

So, for all of you having the same problem, try disabling "Cool n' Quiet" in your Bios or do the following:

Open a Termina, then
1.
sudo su
cp /etc/init.d/powernowd /etc/init.d/powernowd.bak
gedit /etc/init.d/powernowd

2. Just after the line
#! /bin/sh
insert the following:
exit 0

3. Save the file and restart.

Hope this helps.

Eric

Hey guys, I have the same problem, use an ati graphics card, and it happens usually in firefox, i only used edgy for 2 weeks or so but it never happened in there either. Also gaim is open when it happens usually, so I don't know what is wrong with it, but if someone actually finds a permanent fix and reads this, if you email me i will be eternally greatful, so thanks.

I have had similar problems with this verison of Ubuntu. I have an nvidia geforce go 7400 card with the proprietary driver installed all my settings are edited via nvidia-settings. everything is fine for a few hours then I start to get random screen flickers. video playback gets corrupted and with a quick xorg restart everything is fine again, repeat. On the same note I have had the 'no screen of death' screen of death where only my mouse and power button work which usually occurs when killing compiz or beryl and not using '* --replace' eg. logging out/shutting down.

ive had the same problem drove me crazy but finally found that it was memory take all but one stick out install then after install shut down and load each stick one at a time ubuntu now rocks

JerkyChew (memmott) said : #35

I wanted to chime in here because I am having the exact same problem. Like Barshad, I also am on a Dell Inspiron 6000 with an ATI (M300) card. The major difference is that I'm running Fedora Core 8. I have the identical issues - Everything locks but the mouse cursor, and those uhhuh errors appear in /var/log/messages. It seems like the majority of users here are running ATI Radeon cards of some flavor, all on laptops.

I too am running Desktop Effects, as well as FireFox. I am not running GAIM (Pidgin) although it was pre-installed on the system. I wonder if the issue can be traced back to the ATI drivers. Is there any more verbose logging we could try, or perhaps come up with a way to test the video stuff more intensely?

I'm about to boot off a UBCD and see if I can find any hardware errors. If I find anything I will post back here.

Ok this may answer some of your questions -- about 6 months ago i started playing with edgy -- installed it on my desktop with xgl/beryl using the newest ati drivers for my x1300 - and at first i could not resize a window with out locking up - i tried 8.35.5 drivers - then the 8.32.5 drivers - then the 8.28.8 - finally i tried - 08.30.3 - boom no more freezing -- success now i want you to understand i spent countless man hours and weeks trying every possibility to fix this - however whenever i login xgl will freeze and only certain parts of the desktop will load - the first 2 or 3 times then it lets me in and the computer will run for weeks at a time flawlessly even when i really tax its resources - since then i have set up ubuntu edgy with xgl/beryl on more than a few machines - even my laptop amd turion with ati xpress 200m - i have setup both 32 and 64 bit ubuntu xgl/beryl setups and never experienced the same issue that occured on my desktop - if anyone know why it would freeze randomly on login please let me know - also checked my .xsession-errors file nothing out of the ordinary as far as im concerned --

:-) Crazy about UNIX/Linux

I have narrowed the freezing down to my video card - when i remove my
ati x1600 and use my integrated intel - no problems
