It would be nice indeed, but some users have gotten the idea that it's
appropriate to run apport-collect against bugs unsolicited, and everyone
cc:ed on the bug receives notifications of the new attachments.  I'm
afraid there's not much that can be done about this problem in the short
term.

Hi Geir,

Thanks a lot for your response, even if it doesn't fix the problem.
I really appreciate your trying to help although I have a different
distribution.  This goes to show how great a community you all have at
Ubuntu--which is more to than I can say right now about Mint.

By the way, do these various intel graphics cards problems effect all
Debian-based distributions or does it start only at Ubuntu?

Keep up the good work.
Peace,

Eddie

There are lots of different bugs that lead to the same problem -
namely that the system freezes. This particular bug report is for the
freezes that started occuring on April 3rd on many systems. This
problem has been found (the driver was reading ahead too far into
unallocated memory) and fixed. There are other bugs that can cause
this (and new bugs may be introduced), but it is not the same bug.

> Why is it so hard to remedy?

Because each bug has a different fix. They're working on a workaround
upstream that will automatically restart the GPU when it hangs, but
since that a significant chunk of new code it takes time to implement.

If you're system is experiencing freezes, file it as new bug report
with `ubuntu-bug -p xserver-xorg-video-intel`, and also provide the
information described at
https://wiki.ubuntu.com/X/Troubleshooting/Freeze (Batchbuffer stuff,
etc.)

[EddieArt]

This bug has been around for a very long time now--it seems over a year
and a half (not just from April because I have seen related posts dating
to 2008).  Why is it so hard to remedy?  Is it even known if this is
something wrong with the latests Ubuntu releases, latest kernels,
drivers, or just s.th. wrong with the intel graphics card itself?

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[Piscium]

This bug is marked as fixed, however with Ubuntu Karmic Alpha 5, the 3
times I logged in, the screen froze, the first and second times about 2
minutes after login, and the third time about ten minutes after login.
When this happens I have to power off the PC.

I was doing different things when the screen froze, so I do not think it
was the particular action that caused the freeze. I don't know if the
freeze is related to this bug. As someone wrote in the bug description,
there could be different bugs that manifest in the same way (freezing).

Here is my lspci output:
00:02.0 VGA compatible controller: Intel Corporation 82865G Integrated Graphics 
Controller (rev 02)

With respect to Ubuntu 9.04 that I currently use, things are far from
perfect. Watching video streaming is difficult as the image freezes
often, scrolling on Firefox is slow, and most annoying of all is that
once or twice a day the gnome-panel takes up 50% of CPU time, so the
panel freezes. I can often unfreeze it by killing the gnome-panel
process. Note however that the gnome panel freezing is less serious than
the screen freezing that I experience with Karmic Alpha 5.

If you get it with xorg-edgers and karmic daily CDs, it's a different
issue. Can you please do the steps on
https://wiki.ubuntu.com/X/Troubleshooting/Freeze and report a new bug?

Hi,
First thanks for all the effort to hunt this bug. =)

Not sure if this is related to this bug, but someone using Jaunty with
these updates could test the program Blender 3d (Version 2.49a) and see
if these artifacts still occurs?:

http://www.trollwerks.org/BrokenBlender.png
http://i42.tinypic.com/bgww8x.jpg

They occur in the Jaunty live cd without these updates.

You can download the blender on its official site. =)

[jippie]

Probably still early, I know, but after 34hrs I am still in a stable kde 
desktop with a load of effects enabled :o) Before it took maybe 15 to 30 
minutes to hang.
I only installed the released fixes, deleted the my manually edited 
xorg.conf and rebooted ... No tests with prereleased kernels, test 
patches other drivers ...

Hope this helps. Thanks guys!!

It's not blacklisted anymore either.  I've been running a stock Jaunty
system (with nothing from proposed) and I finally got my compiz back when I
installed a bunch of updates this morning.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[nwadams]

i'm using kernel 2.6.28-13-generic (so jaunty stock including updates 
(recommended, important))
I am also using the xserver-xorg-video-intel from the jaunty proposed repo. 

I've been fine over the last 24 hours under normal usage with compiz
enabled and using mostly internet, videos, some wine. No freezes,
lockups, crashes, nothing.

I'm 100% sure this is unrelated but sometimes when i resume from suspend
it crashes x and i have to re-log in.

Is there anything i can run with my kernel that normally causes the
freezes that i can do to confirm it being fixed?

I opened bug #390633 for intel freeze in Karmic when doing "blank
screen".

Thanks for all the help, I think this issue is resolved for Jaunty and I
hope it doesn't come back for Karmic.

With driver in ubuntu-proposed I have had no more freeze (the kind with
the only the mouse pointer working) but I had other kind of freeze. I've
upgraded the kernel to 2.6.30 and I don't have freezes since one week.

My solution: kernel 2.6.30 + intel drivers in jaunty-proposed.

Sure can. No freezes since I installed it, and I installed it as soon

Is there anyone who could give some feedback about a Jaunty standard
configuration/kernel with the jaunty-proposed -intel driver? We need
to get some verification to get this into jaunty-updates.

I would kindly ask people to stop reporting problems with 2.6.30/UXA
here. The bug trail is long enough as it is, and problems with
2.6.30/UXA belong in separate bug reports. Thank you!

[Mike.lifeguard]

My freezes also occur when the laptop is idle for a long time, though I
don't close the lid or suspend the computer: Screensaver -> screen off
(but never suspend/hibernate)...

So it certainly looks to me as though these freezes are different.

[Botond Szász]

I also experience this problem not only when the lid is closed but after
the screen goes blank when my laptop is idle for about half an hour. It
also happened once when the screensaver was active and moved the mouse
to bring the screen alive, and it stopped responding, the screen went
black and I had to powercycle to get control again.

I'm using the 2.6.30 kernel from kernel-ppa/mainline and intel driver
2.7.99.901 on Jaunty.

I just wanted to give an update about my configuration sofar:

Uptime:
 18:58:44 up 8 days, 17:09,  5 users,  load average: 0.45, 0.59, 0.71


With Kernel 2.6.30 from the kernel-ppa/mainline and intel driver 2.7.1
from x-update I have been running stable and without any issues. I have
reactived normal compiz compositing by removing compiz from the
blacklisting and activating it in the apperance menu. Also
suspend/resume works well, even a little quicker than before and with
less errors on resume.

Oded For me the lock up in instantaneously. So we might be having different
issues. I am using packages from xorg-edgers PPA.
And for me also there is no messages in syslog its only in Xorg log

I got the same freeze again (with laptop screen closed) but without the
syslog messages, so its probably not related.

My problem is not an immediate lockup like it seems that Jithin Emmanuel
reported (though I haven't looked at the Xorg log yet) - if I just close
the lid and leave it for a few minutes and open it again then its
usually still ok. For me the freeze happens when I have the screen
closed for a long time - several hours.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[Oded Arbel]

I have a regression in Karmic: after living with the "green" drivers for
a couple of week and everything was fine, I upgraded to Karmic on
Thursday and ever since I had multiple freezes. I don't know if this is
related to this bug, but I'll assume that it is unless someone tell me
otherwise:

I got only one freeze while working, and it looks exactly the same as
this problem: the screen freezes but the mouse still responds and I can
ssh into the machine. But most of the freezes where while the laptop was
on power with the lid closed, which means the screen is actually off and
when I open it several hours later nothing responds - the computer is
still on but the screen is disabled and nothing I do brings it back. I
haven't yet tried to ssh into the laptop when its like that as usually I
need to do something right away and I have to power cycle it.

Anyway, going through syslog I found this which might be related:

There are several copies of these over a period of about 20 minutes,
each almost exactly 2 minutes after another (as can probably be deduced
from the error message) before it falls silent again - I can't tell for
sure whether its related to the freeze, except that these messages have
appeared after I closed the computer when it was working and before I
opened it again when it was not.

Going back through the logs, I found another set of events like this at
another time that I remember the computer freezes, but it was yesterday
and I may be mistaken about this.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[Mike.lifeguard]

Yes, I asked specifically because there is a(nother) regression in the latest 
stuff from xorg-edgers, so I was going to try everything from today and 
downgrade working backwards[1] until I found something that worked. But I'll 
give 2.7.99.901
+git20090611.6d062e9e-0ubuntu0sarvatt~jaunty a try first.

Not sure if I need to reply directly to this thread about this, but here
goes: I am using xserver-xorg-video-intel 2.7.99.901
+git20090611.6d062e9e-0ubuntu0sarvatt~jaunty

You may have noticed that this is not the latest version. The reason is
simple: I just pinned/locked my packages to prevent upgrading, fearing
that things would break (I did not have a single problem with this
driver and the version before, been using that for a few weeks or so
since I switched to jaunty).

Thus, since I'm not running the latest one, I somewhat doubt my
testimonial will be relevant, but here goes, in the hope it is useful. I
am using a Dellbuntu Inspiron 530n, which has this 3100 gpu:

00:02.0 VGA compatible controller: Intel Corporation 82G33/G31 Express
Integrated Graphics Controller (rev 02), Dell Device 020d

I think the situation is improving and hope that by the time intel 2.8
driver is released everything is fixed. Except for these minor issues
I am almost happy with the current situation.

My situation:
Jaunty 32 bit with proposed update
xserver-xorg-video-intel 2:2:6:3-0ubuntu9.3 
kernel 2.6.28-13-generic

I enable Compiz and i open the Singapore image into Firefox without system

For me the bug is resolved.

[zwaldowski]

It seems that I'm now in a weird situation.  I'm on 2.6.28-13 (Jaunty
proposed) kernel with the latest unstable bits from xorg-edgers.  I
haven't froze yet, and can load the Singapore image above with a little
system slowdown.  However, with the same Xorg bits on the 2.6.30-8 given
out _on_ the Xorg-Edgers repo, I get the freeze.  Now downloading the
final 2.6.30 from our so-called Kernel PPA (not on Launchpad) to check
further.

kernel 2.6.30 + packages from xorg-edgers is working for me. So far no freeze 
and everything is pretty stable. Suspend and hibernation is also working,

Thanks zwaldowski I was planing to install it today. So every one has
the problem. Too bad fedora had it from f 10 onwards.
I am planning to give kernel 30 and xorg-edgers ppa a try. People
please continue posting their experience here so that we can lock on a
working combination for all.

Yes, I'm surprisingly sure, considering I had to manually allow 
aptitude to upgrade that package as I had locked the previous 
version. Also, the version 9.2 packages aren't available anymore.

also:

Yeah, Mike, I got freezes under that and the previous -intel build.

I just got the freshly-compiled 2.6.30 final from the "kernel-ppa"
that's not actually a PPA, and I still get freezes.  Rapid-fire ones,
shockingly.  Just like stock Jaunty.

Reini, are you sure?  I use the main US servers and still have whatever
version uses the VirtualSize fix (I can't recall the version number off

@zwaldowski:

Yes, same here. There was an update to xorg-intel stuff yesterday - I'm
reasonably sure that's the cause. Prior to that, no problems. After
that, freezes (though perfect performance until such a freeze). FWIW,
I'm using 2.6.30-020630rc8-generic.

Perhaps I spoke too soon... I've just got about five freezes in rapid
succession with Xorg-Edgers on 2.6.30.  Would somebody be nice enough to
comment when the "Green"-PPA Intel package comes into proposed?  It took
a week for the 2.6.28-13 packages to propogate to Proposed, even with
the depending metapackages already pushed out, so I was thinking it's
probably not up yet.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[zwaldowski]

Jithin, I'm pretty sure it's fixed over there.  I ran the 64-bit GNOME
Live CD from my USB key today for nearly an hour.  I did many of the
things that usually reproduce the freeze, including large images in
Firefox, and switching back and forth between Compiz workspaces with
glxgears and Totem open.  A quick cat|grep of the Xorg log shows that
they indeed use UXA, and I believe it's 2.6.30, so they must be using
the most recent packages baked in with 2.7.1.  That delay helped them
somewhat, no?  Of course, that's really not helpful to me considering I
hate RPM's/YUM with a passion... DEB's/DPKG is my hero.

I'm also seeing this problem - X freezes, but the mouse pointer is

Yes, sorry, it was the that one. I am using KDE as KWin runs much
smoother than compiz. The freeze happened when I started a video in
Kaffeine. I could move the mouse, but that was it. The music from the
video played for a few seconds until it stopped. Had to go with SysRq +
reisub; SysRq + k didn't work.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[David Nemeskey]

True, but the other problems I mentioned are still there...

Also, I am sorry to report that I had another freeze with the "green"
driver. I had set the MigrationHeuristics to greedy before (this
morning), that may have something to do with it? There was no change in
the performance, though.

The glxgears seem to have no significance at all, I usually had a more
responsive Desktop when the glxgears performance was "worse".

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[David Nemeskey]

Installed the "green" driver yesterday, and had not freezes since then.
However, the performance is abyssmal. glxgears reports 1000 fps, 700 w/
Compiz, kwin seems to be able to get the maximum, though. X.org
sometimes uses as much as 70% of the cpu, and the system definitely
feels like it: video lagging, mouse cursor jumping in SDL applications,
etc. I know that the i965 is not the best for playing Crysis, but it
should be able to handle videos and basic compositioning.

Also, as reported before, the KDE 4 screen corruption issue is there.

Wow, thanks!  I'd also been looking for the root cause of this problem
for quite some time! :-)

After a couple of freezes with the x-swat's team drivers, I've reset
everything to current jaunty and installed the above drivers. Currently
I'm back in compiz and no freeze for the last day, and performance isn't
bad either (nothing earth shuttering, but glxgears at 850FPS is a bit
better then what I'm used to from Intel GMA).

That fixed it... although I don't understand what it did, or why it never
did that before. :P Now if I could just get my window borders back...

I haven't had this kind of freeze in several hours now. I have, 
however, experienced another freeze where the screen just froze and 
nothing reacted anymore (no mouse movement, nothing).

I believe this to be a different bug and will report it separately as 
soon as I get around to it.

For now, this should count as positive feedback for the patch in the 
green repository.

I downgraded all my packages from xswat and xorg edgers to ones from
jaunty and installed this package.
One thing to notice is that its affected performance considerably
things are a lot slower and kde 4.2 is pretty mch useless without UXA
because of screen corrupting problem( Well I dont think any one is
going to care about this part).

This is going to happen if you "unredirect" fullscreen windows (System

General -> Unredirect Fullscreen Windows).

When in full-screen mode in Firefox (F11), the entire screen "blinks"
whenever the little alt-text window (or whatever it's called) pops up. It's
very annoying. I think it's more of a Compiz problem than a graphics problem
in general... but it didn't do this before. Perhaps a fresh install of
Compiz will settle it down...

Graphics are really smooth. Window borders have gone all wonky... not
glitching, just... different. And I can't seem to change them back.
http://dl.getdropbox.com/u/455435/LiveJournal//Metacity.png
http://dl.getdropbox.com/u/455435/LiveJournal/Compiz.png
(The "Metacity" screenshot is what the window borders used to look like all
the time, and still look like in Metacity.)

I also can't seem to grab the cube with the middle mouse button anymore...
Somehow I remember being able to rotate the cube with Ctrl+Alt+Button1 or
also with the middle mouse button... but I only see one "initiate" shortcut
setting, so I don't know how to get it back to doing both. Hmm.

Overall though I think these are small problems for which I just need to
find the right settings. I haven't seen any problems with the graphics so
far. Are there any specific tests I should do to try to provoke it?

It mostly occurs with compiz. You might also be able to reproduce it
with other 3D applications, though.

Please note that the compiz package in jaunty-proposed removed the
blacklisting of 965, so you should test both together.

@Thomas Foss: I never had any freezes myself, even with compiz. But I
had enourmous problems with my video card when switching between
workspaces with many windows open, many audio streams, many flash
videos running. Try and check if you feel a difference using the new
patch. You can try using both compiz and metacity and give us your
impression.

The package in the above repository is considered "older" than the 
current version from proposed (which doesn't incorporate Albert 
Damen's patch). It might be difficult for some to select the "older" 
package for installation. It would be nice if somebody would somehow 
bump the version or something to make the package from the above 
repository the preferred package when running "apt-get upgrade".

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[zwaldowski]

The bug has happened both ways, usually faster if one has Compiz.  If
you enable the proposed repo, you'll upgrade to a Compiz that doesn't
have the X3100 on the blacklist.  Be careful, though, as a new kernel
somehow didn't get into proposed and you'll only be able to do a partial
upgrade

Martin, in what capacity I've been able to test it (I'm "addicted" Xorg-
edgers, but I tested a manual compile of it), the patch works
beautifully.

Quick question... does these freezes only happen when Compiz is enabled? I
think I have this bug (because I've got a 965GM chipset and Compiz is
disabled), but I've never had any freezes. Should I be re-enabling Compiz to
see if this patch fixes the problem, or will it remove the Compiz blacklist
automatically?

I tested with both compiz and metacity and with many audio and video
streams simulanteously and it seems to me that this last archive green
package has seriously improved my experience, especially in that there
is no more audio and video stuttering. I never had freezes though, so
I cannot say anything about that.

Re: [Bug 359392] Re: [i965] X freezes starting on April 3rd --- please test new package

[Martin Pitt]

Hello all,

many thanks to Albert Damen for his comprehensive analysis. The cited
kernel patches are only for UXA and don't backport well, so we won't
backport them to Jaunty (at least not now). However, his aperture
patch already got good feedback and seems to fix the problem in a much
better way than the previous VirtualSize workaround which is currently
sitting in -proposed.

Can people who are affected by this and who run a standard
configuration (i. e. NO UXA, NO KMS, NO 2.6.30 kernel, etc.) please
enable this PPA and test the updated -intel driver there?

  https://launchpad.net/~bryceharrington/+archive/green

Please report positive and negative feedback about this package here.
(Please no further feedback about "I also have this problem", or
problems with UXA).

Thank you!

Martin

In fact, there is already an idea in the Brainstorm database :

I think that implementing it could prevent, for the future, problems

poor end-users who end up with an useless computer.

I can say that I have the same situation on my GM45: I used to have both
the kinds of freeze (with/without a live mouse pointer). I'm actually
using the jaunty-proposed package (2:2.6.3-0ubuntu9.2) with the personal
addition of the Albert's patch. I can say that the system is more stable
without any freeze of type A (with live mouse pointer). Sometime I have
freeze of type B: I'm able to reboot with SysReq sequences.

I experience two bugs:
a) this one (where the mouse is still responsive after freeze)
b) another one (where, after the freeze, the mouse doesn't react
   anymore, either)

a) seems hasn't occured for me with the current driver since I
   applied Albert's patch. It occurred quite frequently after I
   downgraded to 2.4 (using the same link you provided above).
b) never really had a chance of occurring before I applied Albert's
   patch (since it seems quite rare) and only occurred once since.

(I will file separate reports for these bugs as soon as I get around 
to it.)

This stable release has been consciously released broken - forget the
deadlock, also extreme slowness with compiz was known since jaunty alpha
1, much earlier than the 3rd of April. The driver should not have landed
beta and should be removed from stable, that's what I am saying.

Of course since I am not an authority I think it is good to ask Bryce
who actually is an authority in Xorg/ubuntu. Maybe there are very good
reasons why we don't want the old driver in ubuntu.

But to clarify: does plain intrepid work for you? I think there are at
least two different deadlockers in jaunty. I know this because I have a
machine with an ATI and with the intel centrino chipset. It deadlocked a
lot. Upgrading to the karmic kernel fixed this. OTOH, I have a machine
with an intel video card. Downgrading the video driver fixed that. So
are you sure you are experiencing the same bug?

It's easy; here is the link, it worked well for me even though compiz is
a bit slower (but I am using EXA and not UXA with the old driver because
it is not strictly necessary to use the latter).

https://wiki.ubuntu.com/ReinhardTartler/X/RevertingIntelDriverTo2.4

Check the Xorg logs before and after doing it to be sure that the driver
version changed (when the intel driver is loaded a string containing
"intel" and the version is shown in /var/log/Xorg.0.log, can't be more
precise because I am using another machine now).

Of course Ubuntu recommends using jaunty. But the main issue here is
the Intel driver, so you cannot purely blame Ubuntu for this
particular problem. So it may be better to continue this discussion on
the freedesktop forum or send complaint mails to Intel?

I don't want to annoy Intel devs (since we really depend on them now
more than ever), but I wouldn't be surprised if they said: "Hey, we
have this new GEM idea, let's first test it with Linux kernels before
we use it on commercial software."

Ubuntu was born from debian for the two purposes of having a predictable
release cycle and high usability. Ubuntu never endorsed using old
releases; instead, fixes for non-LTS and non current releases are
usually not done unless they are security fixes. In other words, using
past releases is unsupported and not adviced by ubuntu. What you are
describing above is debian.

[Bug 359392] Re: [i965] X freezes starting on April 3rd

[Steve Langasek]

No Ubuntu developers are saying that users who want stable systems
should have stayed with intrepid, nor that users who want a fixed system
should upgrade to the karmic alpha.  However, Launchpad Bugs is not a
discussion forum, it is a tool for developers and users to communicate
in order to *get bugs fixed*.  If you're not prepared to help with this
process by testing (including, if it comes down to it, testing with
karmic alpha packages), that's ok, but then please refrain from
commenting on this bug so that the communication channel can be kept
clear for those who *are* in a position to help get this bug fixed.

As it stands, with 548 comments this bug log is already pretty much
useless for tracking the actual freeze bug in question.  One factor here
appears to be that there are a number of different freezes happening,
each with a different cause, but it's very difficult to distinguish
between them because of the nature of the symptom in question.

Some of these freezes are fixed for people using the intel driver from
jaunty-proposed; others require kernel changes which are still in the
process of being prepared for jaunty; others are still present even in
karmic.  To be able to make sense of these bugs, we really need everyone
to do the following:

1. File a separate bug report for your issue, and post the bug number here.  If 
you already filed your own bug and it was marked as a duplicate of this one, 
then you don't need to do this again; but please send your follow-up comments 
to your individual bug report, so that as we begin to distinguish between these 
multiple freeze bugs, your comments stay with the right bug.
2. Follow the directions at 
https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-freeze-test/ to capture 
the information needed to diagnose your freeze, and send it to the bug report.  
Note that you will need to be able to ssh in from another machine in order to 
capture this information, so be sure you have openssh-server installed before 
trying to reproduce the bug!
3. If the freeze is not reproducible for you after upgrading to the 2.6.30-rc5 
kernel needed for capturing the debugging information, please note that in the 
bug as well.
4. For *each subsequent freeze on your machine*, repeat step 2.  This ensures 
that we don't mistakenly end up trying to debug two separate kinds of freezes 
on a single machine without realizing it.

Your cooperation here will go a long way towards helping us break this
confused bug down into manageable chunks.

The live CD has the issue, therefore so does "clean vanilla" jaunty.
