[i945gm] Xorg assert failure: X: ../../src/i830_batchbuffer.h:79: intel_batch_emit_dword: Assertion `pI830->batch_ptr != ((void *)0)' failed.

[mrtof]

I put the laptop to sleep by closing its lid (this feature did not work in Ubuntu Jaunty).
When I tried to restore it, by toggling the power button, I heard the Ubuntu "ready" sound, but the screen staid black/blank. I could still move the mouse.

When I tried to switch to a terminal with CTL+ATL+F1, the screen would appear with weird bars running through it, but I could not access the prompt.

Same bug for me... Need to boot with last Kernel to be able to use my Acer laptop with Ubuntu 10.04

[Ilya Almametov (ilya-almametov)]

The same problem happens occasionally on my ordinal desktop with Intel 845G integrating graphic card. It may or may not happen during different scenarios like browsing in Firefox, working in AutoCAD 2008 in Wine, playing with different desktop settings etc...

[Daniel Voina (dvoina-deactivatedaccount)]

The same behaviour on 2.6.32-16 kernel + DRM from 2.6.33 on x64 architecture

[ratatuia (ratatuiamail)]

How can i be sure that is the same bug?

[Robin.He (hechu)]

I got this bug !!!

[Matt Toups (mtoups)]

Happens on my Intel 845G graphics also (this is a common chipset). Like people above said, it happens somewhat randomly. Sometimes it happens during heavy use, sometimes it happens while i'm away from the computer. The system is unreachable via the network and must be hard-reset.

[jimlovell777 (jimlovell777-yahoo-deactivatedaccount-deactivatedaccount)]

This has happened to me a few times in the past couple days. I have a Sony Vaio i686 running Lucid Alpha 3 with integrated Intel Corporation Mobile 915GM/PM/GMS/910GML graphics. Also happened when I closed the lid of my laptop to suspend. The computer comes back in graphics safe mode.

[Oybon (oybon)]

Same cause, similar effects.

instead of corrupted screen, I get bumped back to logon.

Manually selecting sleep appears to work fine, only closing the lid kicks of the problem, and doesn't set the system to sleep. Big problem if you don't notice as you get cooked laptop in bag.

[Oybon (oybon)]

Also, I just remembered, it worked fine with the live DVD of alpha3.

[Ilan (ilan)]

Recently upgraded from Karmic to Lucid, at which point I began experiencing this issue.

[mukesh agrawal (launchpad-net-mukesh)]

Happened for me when switching from X to virtual console and back.

It sounds as if this is related to bug 462939 so this link may help:

Booting with the kernel option 'nomodeset' might help until kernel version 2.6.33 is released.

[Victor (v-simankin)]

some bug in 10.04b1

[Sebastien Bacher (seb128)]

The bug is still happening on lucid and has over 100 user affects and quite some duplicates, would be nice to fix in lucid

[cberry1982 (flisk)]

Bug is happening with me. I cannot use the 2.6.32-16 kernel. This is one of a few display bugs I am reporting. I just moved up from Karmic which worked pefectly displaywise. I am testing on a Macbook 2,1. Booted into a previous kernel, disabled compiz effects.

[Dick Thomas (xpd259-deactivatedaccount)]

I'm not really sure what i was doing when this happened as I had closed the lid

[Stephen Monteith (stephen-monteith)]

I just finished an update, rebooted, logged in, closed the laptop lid. When I opened the lid, I was at a login prompt and not an unlock prompt. After login in again, all open apps were no longer running, but I no longer get a crash report.

[Dick Thomas (xpd259-deactivatedaccount)]

ok it did it again :)
I closed the laptop lid and it went in to power saving
When i opened the laptop lid again i was greeted with the safe-mode gfx menu (as per bad xorg.conf / missing gfx module)

[Chris Halse Rogers (raof)]

Thank you for your comments. The X team is pretty sure we know what the
problem is here, and that the fix for it got accidentally dropped from
the 2.6.32-16 kernel.

This should be fixed in a kernel update soon.

[Raymond Hill (rhill)]

Just had this crash happened to me. In my case, it appears that whenever I use VLC player, the system will crash sooner or later. Using Lucid Alpha 3 + all updates.

[Jesse (sbjesse)]

this bug is also present in lucid beta 1 (plus all updates) amd64 on a HP Compaq CQ20.
Steps to reproduce: log in, run a few apps (gvim, firefox), close lid (power settings: suspend), and then open. voila: a login prompt instead of screen lock prompt.
/jesse

[Vitaliano Ricca (elirik)]

Same with 2.6.32-17 kernel.
Not a big problem: a bump to the login prompt, with the server restarting

[ajacx (anjo-antony)]

I've also got this on beta 1, 2.6.32-17, desktop intel P4...
Steps to reproduce: log in, open multiple tabs in web browser and system crashes. Keyboard doesn't respond, monitor switches off and I have to reset. Sorry, if this wasn't as helpful or descriptive, will be happy to explain in further detail if asked. Lucid looks awesome!

 just did an update to 2.6.32-18-generic #27-Ubuntu SMP Fri Mar 26 21:13:44 UTC 2010 x86_64 GNU/Linux
 and I am still going back to the login screen whenever I close the laptop lid. When I manually suspend and resume normal lock screen is there and I can return to my active session.

[Ilya Almametov (ilya-almametov)]

I can confirm that bug is still here on the latest 2.6.32-18 kernel. I don't have any laptop lid issues because I use desktop PC, but it continues to crash randomly, leaving system totally unaccessible via console or network.

[Milan Bouchet-Valat (nalimilan)]

That's a very annoying bug I've been tracking for some time. I had already reported it separately some time ago, and provided upstream with some additional debugging information there. I really hope they are going to investigate this further.

[Jared Klingenberger (itsjareds)]

It is still occurring for me in the 2.6.32-18 kernel as well - no change.

[Milan Bouchet-Valat (nalimilan)]

You know, I've reproduced it with the Intel development branch of 2.6.33 too, so it's clearly not gone...

[Robert Hooker (sarvatt)]

The fix is commited and will be released in the 2.6.32-19 kernel shortly.

[Milan Bouchet-Valat (nalimilan)]

Robert: I've been able to reproduce the same kind of crash with the new kernel 2.6.32-19. See bugs 553174 and 553176 - now I'm not sure that's the very same bug. Should I keep them separate and meave this one as fixed?

[Ilya Almametov (ilya-almametov)]

Confirm - it is still crashing on 2.6.32-19

[Milan Bouchet-Valat (nalimilan)]

So let's reopen it for now, waiting for more informations from developers...

[Neil Hauser (neil-hauser)]

I had X crash with this error message upon opening (not closing) my lid, and 2.6.32-19 fixed it - so it looks like there are certainly 2 issues here. Is there more information I can provide to help determine the difference?

[Milan Bouchet-Valat (nalimilan)]

Hmm, I wouldn't like to hijack your report. If other people can confirm the new kernel fixed their crash here, we should just mark it as fixed and continue with other reports. Seems the error message is very generic, and may come from different bugs in the kernel. So, sorry, I'm closing again. I'll track my crash on the reports I quotes above.

[Ilya Almametov (ilya-almametov)]

Milan, if you close this bug then could you please indicate bug # where I can post my feedback concerning this (or similar in symptoms) crash? I can say nothing about laptop's lid close/open issue because I run Lucid on desktop PC with Intel 845G integrated graphic. But I still continue to get those crashes on and on

[Milan Bouchet-Valat (nalimilan)]

dicka: Personally, I've opened bug 553176 as I said above, since I'm tracking this bug for quite a long time now. You may have a look there and see whether that seems to be the same bug, but the best would be to get Apport upload necessary information to a new report, and explain there why you don't mark it as a duplicate of this one.

Often, this kind of X crashes seem to come from a kernel bug; so best would be that Apport detects a kernel oops and report it that way...
