random system freeze when desktop-effects activated with X300 (X600 and X700 too?)

Do you use nvidia?

No, I don't. I have a DELL Inspiron 9300 laptop with an ATI Mobility Radeon
X300 graphics card with the open source driver.
Thanks!

I'm seeing the same thing with a radeon 8500LE. I can still ssh into the system so I'm attaching some debugging info. If you need anything else, please say so, I can obtain new traces etc when it happens again.

File contains:
- X backtrace
- X strace
- dmesg
- /proc/mtrr
- lspci -vvv

Unfortunately I already killed compiz before performing an strace etc.

That is with running an updated 64bit Gutsy:
compiz:
  Installed: 1:0.5.1+git20070712-0ubuntu4
xorg:
  Installed: 1:7.2-3ubuntu4

I also have EXACTLY the same problem with a ATI mobility radeon X300 card on a Dell Inspiron 9300 laptop.

Using Gutsy with all updates

compiz : 1:0.5.1+git20070725-0ubuntu1
xorg : 1:7.2-3ubuntu4

I also made a backtrace for X and Compiz by reproducing the bug with GDB attached to the X process and Compiz process from another computer through ssh.

I made a complete backtrace for X and Compiz and a strace for Compiz. Unfortunately, the X strace was about 147 Mb and still not finished while X wasn't crashed yet, so I don't have a valuable X strace.

I think that we can change the status to Confirmed has there's already 3 person having exactly the same problems. And I think that this bug is critical and should be taken seriously has I can randomly hard crash a computer and block access to virtual consoles.

This is mostly the same as I have experienced (and still do) on a Thinkpad x60s.

It all started after a "aptitude upgrade" sometime sunday (GMT+1) two weeks ago, and also after I (for other reasons) did a full reinstall with Gutsy (tribe5) yesterday.

I'm not quite sure if it is totally random because it happens almost everytime I try to resize a xterm window with the mouse, cursor is then "looked" in "resize mode", but I can still move it. I can't remember to have seen this when not resizing a xterm.

The only way I can get out of the "freeze" is by doing a hard shutdown (aka pulling the plug), when I start the computer again after that compiz is up but I have to do a "emerald --replace &" to get emerald up.

I have not tried to ssh in while in "freeze", I can try that next time it happens, but as I consider "pulling the plug" a pretty fatal action I don't want to do it more than absolutely necessary.

And yes it only happens with Compiz activated.

If you disable the 'resizeinfo' plugin does this still happen?

It is disabled, so yes.

After a bit more testing it appears that this might be a problem with Emerald, and not Compiz, because I've used Compiz with Metacity and had no more problems since yesterday....

Sorry, typo in last post, I ment "GTK Window Decorator", not Metacity...

Petter Aas : Can-you explain me how to do that as I can do the same with my laptop and test if this trick works?

Well the thing is after a few more upgrades, I couldn't start compiz at all, but then i read a post at ubuntuforums where a user had the same problem, he made a new "clean" user and with that he could get compiz running, this works for me on my x60s (intel card), but on two other laptops I've tried it (an older CL56 (ati card) and a brand new T61 (nvidia card)) making a new user and running "compiz --replace -c emerald &" just crashes in the same way as with the original user.

the error I get when compiz crashes is:

petter@*****:~$ compiz --replace -c emerald &

petter@*****:~$ /usr/bin/compiz.real (core) - Error: Couldn't load plugin 'emerald'

I think I saw something like this reported as another bug already, so I will lookup that again instead of going more o.t. here.

back on topic: as of yet I haven't seen the bug described in this thread when running compiz with the second user on my x60s, so I really can't give you anymore details than in my earlier posts on how to reproduce the "freeze"...

In my case, with ATI radeon X300 card, this bug isn't a emerald bug because it also happens in Ubuntu Gutsy with Compiz-Fusion which uses gtk-window-decorator.

The Backtrace that I made was with compiz-fusion and gtk-window-decorator.

There's two different bug that can happens :

Bug #1 : All the screen is freeze but the mouse still works. Typing CTRL + ALT + Backspace doesn't close the X server and it's also impossible to access another TTY, even when switching the keyboard in Raw mode with ALT + SysReq + R. The system can still be accessed through SSH

Bug #2 : Same has bug #1, except that the mouse doesn't even work.

This bug has been tested on Intel graphics, nvidia and ATI, and only happens with ATI.

I have same identical problem with my Dell laptop (intel 810 based card). When I upgraded Feisty to Gutsy I get in trouble with this problem (about one month ago) and I still have it.

I found only one method to always reproduce it otherwise it is very random (and of course only with compiz enabled (I use metacity not emerald)):
- open AWN (avant-window-navigator)
- then try to drag&drop an icon in the awn bar
- freeze

Same identical issues when it crashes, all the screen is freeze but mouse still works, no way to close X server or to switch in console.
Please ask me if you need other infos

I can confirm the same issue as Saivann Carignan reported as Bug #1. Freezing is completely random and the only thing to make computer usable is to press reset key or to open ssh session and restart it from there. Restarting just GDM does not help at all!

I have AMD64 kernel and nVidia VGA running Gutsy with lastest updates.

I can confirm the bug with Emerald too, please someone puts the bug in confirmed status, there's a lot of people with it (http://forum.compiz-fusion.org/showthread.php?t=3544)

I can confirm this bug too. with a radeon x700 mobile..
the screen freezes after some random mouse action and only the mouse pointer is available from then on. but no actions (mouse buttons or keyboard) get through. the only solution is to power down the machine.

On Ubuntu Gutsy with Compiz 1:0.5.2+git20070918-0ubuntu5 and xserver-xorg-video-ati 1:6.7.193-1ubuntu1

the problem seems to have disappear. Since two days, I use a ATI radeon X300 card with compiz fusion, I've experienced no crash and nothing unstable.

Happened to me again, just few minutes ago :-(

And again in such short time. Disabling desktop effects since it's not possible to work that way.

Robert Hrovat, can you specify what graphic card you are using and which version of Ubuntu, compiz and the Xorg drivers for your graphic card?

the bug is still present when compiz is enabled (if desktop effects are turned off, i haven't yet experienced such a freeze)
my graphic card is a ati x700 mobile
i have the latest ubuntu gutsy and xorg drivers installed

Of course. Altough I wrote that few comments before. Here is more detailed configuration:

VGA: nVidia Corporation NV43 [GeForce 6600] (rev a2)

I hope that helps. Normally I wouldn't bother but compiz has a really nice feature to make wine apps windows open in the right order which I really really like :-)

Right before freezing, I've noticed there was something added to system logs:

1st freeze (one line only):
kern.log:Sep 26 09:53:32 asgard kernel: [40564.951565] NVRM: Xid (0002:00): 6, PE0000 08b8 ffd38e47 00003640 00000000 ffc8823a

2nd shortly after reboot (I don't know if first two lines are because of compiz since it froze at 10:30):
kern.log:Sep 26 10:13:13 asgard kernel: [ 530.138908] NVRM: Xid (0002:00): 6, PE0000 1040 00efebe7 0000faa0 00ffffff 00ffffff

Gasp nvidia, that seems to clearly means that this bug affects different graphic card.

Can someone that uses a ATI radeon card can confirm if the problems are still there?

Also have the random freeze with an always up2date Gutsy and .... Nvidia 7300 GS on nforce 410 Chipset (mcp61)

The screen randomly freezes, sometimes I can move the mouse, sometimes not...

I experienced the problem once with desktop effects off. But have not reproduced since.

With latest update, the bug came back again with ati radeon X300

Bug gone for me with latest update.

In fact it still sometimes freezes but for 10 to 15 seconds....

With the latest Gutsy upgrade now I have another freeze type and may be the old one too (random freeze).
If I lock the screen, it just freezes when I enter the password and click unlock, the screen remains black, only mouse works and I have to shutdown the laptop. (intel i810)

I'm seeing this same issue on a Dell Latitude D610 with the following video adapter:

01:00.0 VGA compatible controller: ATI Technologies Inc M22 [Mobility Radeon X300]

The freeze occurs randomly, but the common theme seems to be when a dialog box is being faded in on top of other windows. For instance, I've had it occur when selecting from the dropdown list of URLs in Firefox, and also when using Alt-Tab to switch among windows.

As others have reported, some times the cursor will still responsd (always stuck with the "pointing hand" icon), other times nothing will respond. In both cases, Neither Ctrl-Alt-BackSpace, nor Ctrl-Alt-F1 switch out of X. I have gnome-power-manager set to power down when I press the power button, but that does not work either. I have to hold down the power button to reset the machine.

I just installed Gusty and I'm also experiencing exactly the same problem as MichaelElkins described above, but on a Dell D810 (with radeon card too). Ctrl-Alt-BackSpace doesn't work for me either, but Alt-SysRq-b does "work". It happens so often that there's no way to do any work with that enabled (why is it on by default I don't know), so I turned it off. I tried using the proprietary ATI driver to see if it has the same problem, but then I would just get a message saying the composite extension isn't available. Conclusion, desktop effects not usable on this laptop in any way.

Same has jmspeex, Ctrl-SysRq-b works and Ctrl-Alt-Backspace doesn't work.

I also noticed something special about this bug. I experienced the bug yesterday too but I noticed that one on my terminal windows wasn't freeze. It was pinging Google and the terminal didn't look like if it was freeze at all. I saw each answer from the Google servers in the terminal windows one by one like if it was working normally. However, I was still able to move my mouse but nothing was happening when I clicked somewhere. Ctrl-Alt-Backspace didn't work.

So maybe that this strange behaviour can give some clues about the bug! The X server doesn't look like being completely freeze.

The X700 [1002:5653] seems to be affected too. We may have to blacklist it.

The same things happens for me (lockup, mouse works, ctrl-alt-fn doesn't, magic sysrq does):

ASUS G1 laptop:
01:00.0 VGA compatible controller [0300]: nVidia Corporation GeForce Go 7700 [10de:0397] (rev a1)
Gutsy was installed from the beta DVD, but I'm using my old home directory (and therefore old settings).

Without compiz it works fine. From my perspective I don't think compiz (at least on nvidia) is quite ready for prime time yet.

(I should note that I tried it with a "clean" home directory as well and saw the same issues...)

Bug, witch was gone, came back with latest updates.... and worst than ever....

After each freeze and so, each reboot, it seems that my ubuntu tries to detect the screen resolution.
And the result of that detection is not always the same!

Can't believe it:
My Linux is getting human! It is getting more and more imprevisible!
(Can it think?!?)

Just a note, the card with which the problem happens is a Radeon Mobility X600, so you'd have to blacklist that as well. Let's put it the other way. Has anyone had any success with any Radeon Mobility card?

> Just a note, the card with which the problem happens is a Radeon Mobility X600

Not true.
If you read the bug comments you'll notice Nvidia cards are concerned too! (including me)

Since last week updates, my nVidia based computers no longer freeze.

I've run into a similar problem as everyone else here, running compiz-fusion with Feisty Fawn. Same type of freeze, the mouse will move but not respond to clicks or keybaord input, and sshing in still works. However I've only had it occur while resizing windows (though sometimes I can resize without any problems). I've got an Intel Mobile 945GM graphics card.

I have an ATI Mobility Radeon X300 and I haven't have any random-freeze
since I updated my Gutsy one week ago.

Sorry, do you think that it's necessary to blacklist all these 3 cards?
There's a way to unlock them?
I have an ATI X600 and I haven't had any freezes in the last 3-4 weeks so there's a way to unlock compiz by myself?
Thanks

Same here

I have an ATI X700 Pro, and I think I'm having freezes in Gutsy since one of the last updates. Everything was ok during the previous two weeks.

Please either provide an override for the blacklist, or don't add the X700 to the blacklist. I have an X700, and I've been using compiz-fusion heavily since it got included.. but I've never had it freeze up on me, and I'd like to continue using it.

i second the request to provide an override for the blacklist at least!
i haven't had any problems with my X700 for the last 2 weeks. so it would be nice to continue using compiz

Never had a problem with my mobility x600 and compiz-fusion under Gutsy.

To override the blacklist do this:

mkdir -p ~/.config/compiz && echo SKIP_CHECKS=yes >> ~/.config/compiz/compiz-manager

Since the latest Compiz updates, I can't get to reproduce the crash with my ATI radeon X300 laptop. Everything suddenly seems fine.

I still sometime get a backtrace from X ( but not from compiz.real ) when closing one or more windows, but it doesn't crash the computer. I can not even see if the computer freeze for a milli-second, I just get the backtrace in gdb through ssh session and the computer doesn't crash.

I attached the backtrace, in case this would help.

Saïvann:

SIGPIPE is a normal signal. If you want to be running X under gdb, you should probably run this command in gdb:

"handle SIGPIPE nostop noprint pass"

to ignore SIGPIPE and pass it through to the slave program. Otherwise you'll have false "crashes" that are just the result of hitting the debugger.

Thanks for this information! If I get a real crash, I will report it.

I have an HP nw8240 with a PCIE ATI FireGL v5000 (r420, lspci lists it as X700) that is blacklisted too. The SKIP_CHECKS workaround Travis posted works for me. I haven't had any crashes in the Gutsy beta with compiz enabled.

I have a HP Pavilion zd8000 with a ATI Mobility X600.
I use the xorg-driver-fglrx package and activated the driver in the Restricted driver manager.
Compiz-Fusion works fast, nearly without crashing and with almost all functions. I have no problems at all.
And for sure it runs alot faster with this restricted drivers.

Seems last update corrected the bug for a couple of hours and then it came back again...

Nvidia 7300 GS on nforce 410 Chipset (mcp61)

Same issue here, after the last fix, the systems freezes on Screen Saver Activation, then after restart again stops randomly. ATI RADEON.

Forcing SKIP_CHECKS=yes, and everything appears to be working perfectly.

HP nc8230
ATI Radeon X600

Same thing happens to me when using feisty or gutsy. only happens if I use avant-window-navigator though. If I use the regular panel it doesn't happen, I have NVIDIA 7600 GS 512MB. It doesn't happen at all using opensuse 10.3 even using avant-window-navigator so it must be something related to ubuntu. I remember when first using feisty it didn't happen until a few months ago after an update pushed. so it must be something in the latest ubuntu dirivitives.

I can confirm this behavior with latest update: computer ran fine after it until I left my computer for lunch.
When I came back, I found it "freezy" on the screensaver.

Rebooted (Ctrl+Alt+Print Sceen+B), used the computer for ten minutes and it freezed again when I resized a window.
No Avant-Window-Navigator running at all.

I was tracing syslog using ssh, here what the freeze gave me:
Oct 13 15:30:49 gromit kernel: [ 2326.662649] NVRM: Xid (0002:00): 26, Ch 000001ff M 00001ffc D ffffffff intr ffffffff

Then ssh server went down.

I pressed ctrl+alt+print screen+A: the computer "unfreezed" and I got the logs attached

@ Martijn van de Streek and Konrad Paumann

I am also using the X700 under Gutsy and are sometimes experiencing this error and I suspect I could have something to do with one or more of the plugins for compiz. Right now I have overrided the blacklisting and are back on track, but I do fear the error will return.

Could you perhaps provide a list of what plugins you have active, since it does not crash in your cases? I might then try to rule out what plugins might cause the crashes.

I use the "Normal" effects setting from the Appearance dialog.

Martijn

I identified that using aiglx was the problem for me. I switched back to
using xgl and everything is fine again. Thanks

I've switched back to xgl, but it didn't work for me, IT lasted something like 12 hours before de las freeze.
PLZ can anybody help us? it's a sham that the Radeon X300 card must be banned when on feisty compiz work like a clock.

I have the suspicion that it is the "Animations" plugin that causes the freeze when one of the effects are activated (perhaps some pointer goes spoink). If this is the case, then further investigation would be to identify which animation is to blame.

So far I have deactivated the animations plugin and it seems to go ok :-)

This makes a lot of sense, I will try to investigate this too with X300
in few days

@Arngren
That's an interesting observation. But then the problem would probably be visible with all video cards, since there is nothing specific to these cards in the plugin.
Oh, and while you're at it, can you also try with Animations enabled, but with focus effect set to "None" in settings manager?

That's true with the videocards that it should be common - but there must be something which is common for these few cards to cause the freeze (specific interface, buffer size perhaps etc.). I mean pointers in sw can make even the best code screw up - it's a long shot I admit it, but it's my best guess.

So far I have not had any freezes with the animations off, but I'll give it a try with the animations enabled and I assume you mean the "focus animation" effect inside the animations plugin should be cleared - at least that's what I have done :-)

 Problem still persists in Gutsy 7.10 release. I have a Dell Optiplex GX280 with a VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]. Enabling Extra desktop effects caused UI to lock up after an unspecified amount of time (usually within 10 minutes).

 I disabled the animations plugin as suggested in this ticket. Lockups have NOT occurred for over a day.

  A confirmed functional workaround seems to be to disable the animations plugin.

Scratch my above statement. All was fine for about a day. I logged in today (still w/ animations plugin disabled) and my display froze up as described in this ticket (mouse worked but I couldn't click anything....keyboard was unresponsive) shortly after I started working.

 I disabled effects as this is my work machine. For what it is worth, I had compiz-fusion manually installed on Feisty for several months without a single incident on the same workstation.

  Using the ATI commercial driver that one gets through Ubuntu repos cannot be used for Desktop Effects because when installed via the Restricted Drivers Manager it states when trying to activate Desktop Effects that "the composite extension is not available". So until now, I had to use the free Radeon xorg driver (which locks my desktop up).

  However, on a whim I tried using Envy to install the latest commercial ATI driver. I did and I enabled desktop effects. There was no composite extension complaint. All went as expected. YAY!!

   I've been using desktop effects (incl animations plugin) with this Envy installed commercial driver for my X300 for 2 days now with no hangs.

Hi,

Using latest radeon driver from Tuomod Volden's PPA on X600 XT (RV380), it works fine. I do have some freeze on gutsy while resizing nome-terminal.

Regards,
Étienne.

After a bit more testing it appears that this might be a problem with Emerald, and not Compiz, because I've used Compiz with Metacity and had no more problems since yesterday....

i think i have the same problem. When i use emerald, system freezes in about 1 min. after startup. even mouse doesn't move. and i don't get any errors. but when i use gtk-window-decorator there is no problem. i am not sure that this is the right place to post this issue but sorry this is my first bug report. by the way i am using gutsy with latest updates and ati x500

Exact same thing happens on my system. Has this bug been fixed yet? Is it possible to update/upgrade something to get it to work?
