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.)

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?

[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.

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.

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!

[LanoxxthShaddow]

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.

Lanoxx

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

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.

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, 
though desktop effects are getting disabled after that.

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:

The glxgears seem to have no significance at all, I usually had a more

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

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...

[Thomas Foss]

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.

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.

[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

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.

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.

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

@José Tomás: Clean vanilla jaunty has this issue. It was released on
April 23rd. The development version before April 3rd did not have this
issue. It should be possible to get an alpha version from before this
date, but I don't think the in-between packages are readily available.

@zwaldowski: I don't think you qualify as a "normal user". You seem to
be far to technically apt for that. While it is pretty hard to get
bugs in Jaunty fixed now (the upstream developers aren't terribly
interested in fixing "old" stuff, the SRU process is cumbersome but
necessary to avoid breaking new things in a stable release), this is a
great time to get bugs fixed in Karmic. This is not a recommended
workaround for "normal users", but it is the way technically
knowledgable users like yourself can help make sure the problems are
addressed before the next version. If you file a new bug report
(preferably with the ubuntu-bug command) using Karmic, that will
definitely help. Karmic also has better tools for debugging freezes
like this.

Because we are certain that the clean vanilla jaunty install doesn't

[José Tomás Atria]

IMHO, please stop with all the discussion about what should have been
done, or if linux is ready for the desktop and whatnot.

We have a stable release that is recommended as stable to users. ALL
users.

this stable release has a known problem with intel drivers, the
problem was reported as a bug and is being worked on. This is the
proper way to address the issue.

When a workaround is found, it should be recommended to all users, or
if it entails a regression, it should be pushed into the update path
as a temporary fix (unitl now, i haven't found the problem again with
the updated intel drivers in the jaunty backports).

"upgrade to karmic alpha" is not a viable workaround for users, so
please, recommend what to do to avoid this problem within jaunty,
while the bug is solved.

Has anyone bothered to thoroughly check which update produced the
error for the first time?

By the way, this is what most of people do with Windows. Even more : 
most of Windows users just stay with their OS until buying a new computer.

If we want to look in a "very end-user" perspective, a computer is only 
supposed to work with the OS it was shipped with. Dell sold me a 
computer which is supposed to work with Hardy, and it does work with 
hardy. The fact to install a Jaunty *is not* an end-user behavior. The 
first line of the GPL is very clear on that point ;)

That's very odd... the problem definitely wasn't around in Intrepid, at
least for me.

I am a "14 years old" Linux user, I used it as my primary OS since
1995, when I bought my first own PC I put Linux on it.

And I have to say that there are many projects in GNU/Linux that have a
great history of very careful, thoughtful software development, such
as editors, binutils, gcc, apache, perl etc. These have self tests,
etc and go through a very rigorous development process, so I never
hesitate to trust them with my business. They find bugs automatically
and fix discovered bugs. 

However, I think that any sort of a project that "does not fix bugs"
may lose trust, and has a limited future, and I am greatly hoping that
Ubuntu would not take that route.

We cannot really recommend to people to "switch to pre-alpha Karmic",
either.

I do realize that 1) GUI stuff is not as amenable to automatic testing
and 2) Ubuntu is trying to do this on a shoestring budget, so the
situation is understandable, but in some ways it is unfortunate.

I am a 100% Ubuntu user, this is what I use at home and what we have
at work, so this is not meant to be jeering from sidelines. But I do
feel that I have a deep interest in seeing my platform remain a
reliable, trusted friend. 

Personally, on the balance of "wanting new cool stuff" versus "wanting
to have reliable software", I tend to be skewed for the latter.

I tend to agree with you.

How would one reinstall the old driver? I didn't think it was an option.
Heck, I'd downgrade back to Intrepid if I there was a way to do it. There
should be a "downgrade" button that's as big and shiny as the Jaunty upgrade
button was.
(Or maybe the upgrade buttons could just have little warning labels on the
side... like cigarettes do.)

A piece is missing here "the whitelist" would be created based on user

As a 12-years old (as a linux user) linux user, I have to say it's true.
I hoped for a long time that Ubuntu would have been different. 

In this case, putting the old driver back in the distribution and
starting to chose the right driver based on user's feedback until the
too many intel issues are solved, would be mandatory.

@Bryce, it's easy to put back the old driver in the distribution, and if
there is not enough manpower to create the whitelist, I would chose the
old one as a default. May I ask you "why not"? 

The old driver is already "available" in jaunty in a PPA; but the point
here is to provide a system that works out of the box. I recall
everybody that current intel driver is also extremely slow unless you
tweak Xorg.conf. Which is not something we expect from the ordinary
_ubuntu_ user.

It was already unacceptable to have jaunty ship broken. But if in karmic
issues are not solved, please, please, rethink the decision of using the
new driver. It's just too early. If intel sees that no one wants their
new puppie, they'll start improving it.

+1 at Bernhard. I have been following this bug closely, and i read the
whole 300+ comments, but i got lost in regards as to which packages
are affected, and what versions should introduce fixes, apart from the
backported xserver-xorg-video-intel mentioned above.

@Bryce: could you give us a little more info on he current status of
the bug, to further help isolating the issue and the affected
packages?

thanks!

I see the exact same problems with UXA too (and kernel 2.6.30-rc7 plus
the intel driver from git for that matter).

So I guess these should be reported upstream.

As was mentioned before, this bug does not exist in UXA... I wouldn't really
call it a "fix", it simply never arose in that code. But there are many
unrelated valid reasons why Ubuntu doesn't use UXA yet.

Caveat emptor.  When I tried UXA on Intel GM965 in Jaunty, I suffered
from two show-stopper bugs: (1) memory leak that would eat up all the
RAM within a day or two, causing all applications to be swapped out and
(2) X would crash on every suspend & resume, requiring me to log in
again and restart all the apps.  Both bugs affected me with stock Jaunty
driver as well as xserver-xorg-video-intel 2.7.1 from the ubuntu-x-swat
PPA.

So, I wouldn't recommend UXA as the panacea.

I have the same hardware and, as I reported here recently, this bug is solved 
with UXA:
https://wiki.ubuntu.com/X/UxaTesting

UXA works perfectly here. Just add that line to you X config, reboot and enjoy 
your Ubuntu install.

UXA fixes all the bugs of the previous driver: Display corruptions and X 
freezes. Plus, it doesn't introduce _any_ bugs.

So, I'd really recommend it to you.

You better not upgrade. Wait till stable drivers are available. It also
needs 2.6.30 kernel. And I believe that is never going to be available in
jaunty, So you better wait till karmic is released. Hope it will be fixed by
then.

I'm having a similar problem on Fedora 11
(https://bugzilla.redhat.com/show_bug.cgi?id=499245) on GMA 945. Its not
100% the same problem (for example, xv works fine for me, its SDL that
freezes), but its more likely to be related to your problem this this
launchpad ticket.

The Fedora freeze also seems to be Intel driver related. I'm really not
pointing fingers anywhere and I got relatively very little flak on my
machines compared to other people on the list, but the Intel GMA driver
scenario is pretty horrible right now - I'm actually advising people not
to upgrade and to buy non-Intel graphics.

No I don't think it is safe to say so because I had these freezes even
while seeing the picture in firefox (dunno why it doesn't work now).
However, I can't be sure I have the same freeze.

*This* bug is about freezes on i965 with EXA.

Extreme Compiz slowness ought to be a different bug, though I cannot
give you a link right now.

BTW have you tried disabling vsync in compiz and in driconf?  That
helped a lot for me (using EXA; I had no extreme slowness in UXA by
which I suspect vsync is broken with UXA).

I have the freeze mentioned in this bug, but the image loaded properly
for me in firefox. Now it is black (bug in firefox?) but if I download
it I can see it. But different programs may use xlib in different ways,
so that means nothing.

It should be included in the next build of the xorg-edgers PPA (

installed this PPA it's quiet hard to get rid of it again... Please
read the warnings on the website.

I guess it would be wise to wait for the next release of the intel
driver and use the ubuntu-x-swat  PPA
(https://launchpad.net/~ubuntu-x-swat )

So, enough bug spam

dont forget though im not even on an intel chipset but an nforce 750i
chipset. it was rather prevalent for me in jaunty wiht nvidia 180.44
driver in repos but wiht the same driver in karmic it seems like it
was something else as the issue has yet to surface.

They says that the bug is still present in the 2.7.1 version of the
driver. They also speak about a possible patch for the kernel.

I don't know if it is supposed to be. That is, I don't know if the
driver treats the 965GM and GM45 differently in any way. What I do
know is that the function IS_I965G in the driver returns true for the
GM45 chipset (see my first long comment on bug 370777), so it may be
similar enough that it is the same underlying problem. The workaround
uses the IS_I965G function to decide whether to apply it or not, so it
will be applied to your GM45 chipset.

However, all the duplicates of this bug were reported on 965GM
chipsets, so I think it is best to keep it separate until proven
otherwise (or someone who knows the hardware and the driver well says
that they're basically the same). If you can get GPU dumps from a
freeze using the 2.7.1 driver from the x-updates PPA (Personal Package
Archive) and file it in a separate bug report, I think that may be
helpful.

But is it supposed to be an affected chipset? Before of the

have a further freeze should, I open a new bug report?

You may very well have the same symptoms on an i945. It just that
debugging is much easier if we keep the bug reports for different
chipsets separate, and debugging is really our goal here. Please ssh
into the machine and get a backtrace (or more importantly a GPU dump
as described in this bug report). But please upload it to a separate
bug report. If it turns out to be a duplicate of some other bug, it
can be marked as such. If it doesn't add any new information to that
duplicate bug it avoids having lots of redundant information in the
bug report, and any new information can be added in a comment to that
other report. Our goal here is to keep the bug reports simple, since
that makes debugging easier.

You have GM45 chipset. Some of the newer chipsets don't list the
numbers and names in the lspci, so I prefer to look in Xorg.0.log.

Yes, there is.  Even if this ultimately turns out to be the same bug, it's
very important for our ability to triage bugs that people with different
hardware open separate bug reports, unless otherwise indicated by the
developers.  Otherwise, when the freezes people are seeing *aren't* related

the comments in a single report just makes it incredibly hard for the
developers to extract relevant information from that report.

So please open a separate bug report for your problem.

I must respectfully disagree.  My compiz has never been this snappy
before.  Stability wise it is also a lot better than the stock intel
driver in Ubuntu 9.04.  My system has been running flawlessly since
yesterday with Compiz and UXA enabled. Otoh I only run Firefox,

I do agree.  Regarding bug number one, one could notice that MS leaves 
more testing time between the beta version and the final version than 
Ubuntu for a whole cycle.

Please, if the aim of LTS version is to provide a certified stable OS, 
do not advertise the other versions, especially when there still remains 
a critical crash for a widespread GPU.
Now, I'm obliged to tell all my friends I converted to Linux (namely : 
Ubuntu) to not update to Jaunty because there is a critical bug that 
makes the computer simply unusable.

I have nothing against the fact to *release* Jaunty with that bug, but I 
don't understand why there should be a big button "DOWNLOAD UBUNTU 9.04; 
enjoy an improved user experience" on the main page www.ubuntu.com.


A part of that, I'm sincerely grateful for all your work to make free 
software more human. I didn't paid for Ubuntu[1] and I know the first 
line of GPL : No warranty ;)


[1] Although, I paid for a Dell with Gutsy pre-installed.

true "human beings" could also just opt to stick to 8.10 or choose the 8.04
LTS release. "Human Beings" should read release notes. And the advantage of
fixed 6 month schedules is that you can easily fall back to an earlier
release...

The changelog sounds promising:

We have verified that several of the reported bugs of GPU crashes,
(mouse continues to move, but otherwise X is totally unresponsive), are
fixed with the commit by Keith Packard in 2.7.1 to correct the
computation of the batch space required. If you have previously reported
a GPU-crash bug in bugs.freedesktop.org, please test with 2.7.1 and
report your findings in the bug. If the crash is fixed, please celebrate
with us!

If the crash persists, please attach the output of intel_gpu_dump
available here (and hopefully packaged in your distribution of choice
soon):

git://anongit.freedesktop.org/git/xorg/app/intel-gpu-tools
(Requires Linux kernel >= 2.6.30)

Thanks to everyone who has helped to improve this driver!


Thanks for packaging it so quickly and lets hope we can celebrate with
the developers :)

Hi,

I just had to reply to you "off list", so to speak.  That answer was
very well put, thank you for taking the time to formulate and writing
it!

I have been sitting here, in my corner of the world, considering doing
the very same thing, but I guess I lack the proper words.

Thanks
 /Joachim - From Sweden, with the same bug, patiently awaiting the wizards to 
fix it. :)

YMMV, once per day here.

The problem here is, that 'we' don't know whether people are working on
it and also if there is anything 'we' can do to help. Please keep us
up-to-date.

The only thing to criticize here is that this showstopper was known
before jaunty was released, so IMHO it would have been worth delaying
jaunty (it now went through the press and might have caused more much
more damage).

[wirechief]

I realize that this bug is present across all linux platforms, it is a
tough nut to crack and am willing to
bear out these freezes, knowing that uxa is not completely ready for
me is not a issue, I am not ready
to change course, if i should of given more information on my latest
freeze I can try to get it to come back
and provide whatever reporting i can.

Matches my experience even with latest kernel (.30-rc5) and video-intel
from git (2.7.99+) - yes *with* uxa. Issue appears usually between 6 and
24 hours of use. I can still ssh into the machine etc...

@SebastianG: This has been fixed in 2.6.3-0ubuntu9.2 that hit
jaunty-proposed today. See bug 370777. If you don't want to wait until
it comes to your mirror, you can get a binary from

[wirechief]

It would make sense if someone could make a script that would test for
all the "proposed" fix's and those
users who are not meeting the test be advise that they are not running
the fix's and their results cannot be
judged valid against this bug. too many variables for an easy id of the fault..

zwaldowski, while I sympathize with the fact that your freeze is not
fixed by the tricks that have fixed other people's freezes, losing your
cool at Martin is not going to result in people wanting to help you.

For what it's worth, from the non-correlation of your freeze with the
workarounds others have found affected things for them, I suspect
whatever issue you have is unrelated.  Since we are focusing this bug on
the class of freeze which is mitigated by adjusting Virtual, if that
workaround does not affect your freeze, then you should look elsewhere
for a fix.
