Hi

I have added the 3 files you asked for Fabio.

The problem I am reporting is easy to reproduce; I only need to open Gnome Image viewer and change pictures fast or zoom on large pictures - and it will freeze. Same happens when I open lots of tabs in Firefox from Liferea.

Thank you for checking my bug report.

This happened to me too. Both using Kubuntu 12.04 Beta1 AND Ubuntu 12.04 Beta 1.

It could be random Freezes but i also had the browser open. (Chromium). Ill attach my logs too.

Oh i forgot to write down my Specs:

Macbook Pro 5.5 13" Intel® Core™2 Duo CPU P7550 @ 2.26GHz × 2
8 gb Ram
Ubuntu 12.04 Beta 1 (all Updates) 64 bit.
Using recommended Nvidia Drivers from Ubuntu.

Happened again. After 1 hour using the Desktop just fine and then it froze when i tried to watch a youtube video.
Logs following:

Happened again for 3 time today. Last time I had Firefox with 13 tabs, Transmission running and Thunderbird when it froze hard (would not respond to CTRL+ALT+FX). Will add new logs (tar.gz file):

Feel free to ask if you need more information.

Hello
Does this happens everytime watching video ?
Can you try to work in unity-2d to see if compiz is envolved ?
No errors logged in attached files

I tried working in Unity 2D for almost 2 hours now and i could not reproduce the bug.

I have tried:

Running 12 Tabs in the Browser at once, 2 youtube videos each 40 minutes long.. opening and closing applications

from what i can tell everything runs buttersmooth.

Just giving a short update: The 2D Unity interface is still solid without crashes after more than 24 hours of uptime.

Hello Christian
I need a service, can you please run unity 3d till it freeze then run in a terminal

When the freeze happens next, please do this:

1. Switch to a virtual console: Ctrl+Alt+F1 and log in.
2. Run:
    gdb `which compiz` `pidof compiz` | tee /tmp/compizbt.txt
3. At the (gdb) prompt type:
    bt
    quit
4. Revive your desktop by running:
    sudo restart lightdm
5. Attach the file /tmp/compizbt.txt to this bug.

Thanks in advance. I hope we can make debugging steps like these simpler in future :(

Hey,

I am sorry that it took me so long, but you know how it is: when you are waiting for a bug to happen - nothing happens.

So i got into gdb and createt that txt, but on the bt command gdb returned "no stack". I took a look into the file but i dont think it will be very helpfull to you.

I'll attach it here.

Same problem here on my laptop:

lspci | grep VGA
01:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800M GT] (rev a2)

1) Desktop freezes after a while, not very long, could not even install synaptic package
   - both Ubuntu and Ubuntu 2D

2) After hard reboot, installed some packages (ssh to be able to connect from remote) from a Virtual Console,
a was switching to immed. after login screen showed up.
After some time of installation:
As soon as I switched to where I assumed graphics, frozen again.
No Ctrl-Alt-Fx any more, seams like dead, but ...
ssh from remote works!

3) WIth my situation the compiz experiment requested earlier is pointless, since no compiz, no metacity yet, and freeze on lightdm.

Here a strange excerpt from /var/log/syslog, which I do not understand without studying Kernel code, however, maybe
somebody may know:

Maybe this helps,

After my last posting, I found out, that installer went for nvidia driver - nvidia-common.

When I tried nvidia-common (not installed per default in 11.10), it did freeze my laptop as well and I removed it again.
(was not reported that time).

Removed nvidia using:
  sudo apt-get --purge remove nvidia-common nvidia-current nvidia-settings

Rebooted into 'nouveau' driver, which is working now for a longer time than before with nvidia. Will post further results.

cuK

So here the result of my last post:

Running now for the last 10h without problems or freezes.

Summary:

11.10: Installer picked nouveau for nvidia graphic and worked
(with problems mirroring external screens, but that's a different issue)
  installation of nvidia-common (to try the external screen thing) led to
  freeze of desktop within minutes (3D & 2D).

12.04: Installer picked nvidia-common with the same result as above.
  Freeze of desktop within minutes (3D & 2D).
  Removing nvidia-common and running nouveau helped against it.

Hope this helps,
Klaus

Hi Klaus,

I want to try the same thing as you did. I disabled the Nvidia Drivers under the "Additional Drivers" Option in Ubuntu and i am now working in 2D Unity Fallback Mode. How do I activate the Nouveau drivers? The software center tells me that they are already installed.

Or do i just have to enable 3d support somehow?

(Fonts and Windows are a little bit skew and hard to read right now)

Since my last post Ubuntu have frozen about 4 or 5 times (less then before but still to much). I have not been able to run the suggested commands, because it didn't respond to CTRL+ALT+Fnumber (hard freeze, so had to turn off the power to reboot).

I still have a clean install of Ubuntu 12.04 Beta 1 (have not installed the proprietary AMD graphic driver). Its fully updated, and no other PPAs (only installed some packages from apt-get).

@Fabio:
When I run “apport-collect 947433” I get the text “waiting to hear from Launchpad about your decision...” and nothing more happens.

@Daniel:
I tried your suggestion but did not get any txt file in tmp (tmp/compizbt.txt). When I typed “bt” I get the respond “no stack”.

I cant use Ubuntu when its so unstable, hope it will get fixed. I will try out other suggestions if you post it.

Thanks again.

I haven't tried ubuntu 12.04 Beta 1 yet as it is too slow to download at this point, but I experience random freezes as the above mentioned in a fully updated kubuntu 12.04 Beta 1. An external usbmouse works fine though. I've tried to move back to the 3.2.0-17 kernel and even though it seemed like it solved the problem for a while it happened there as well.

I'm on a HP pavilion dm1-4100 with amd all the way. No indications in any of the logs about what is happening as far as I can see anyways. Right now it is so bad it is almost impossible to do anything, but the strange thing is that everything runs smoothly up to the point when the freeze happens.

I also notice this problem in Firefox, going to Ctrl+Alt+F2 and running "killall firefox" (if the system is awake enough to run the command), seems to fix it until Firefox freezes the system again.

Thank you for taking the time to report this bug. We have tried to recreate this on the latest release of Ubuntu and cannot reproduce it. This bug is being marked as Invalid. If you believe the problem to still exist in the latest version of Ubuntu please comment on why that is the case and change the bug status to NEW.
