Very likely X/driver problems.

Yes, it may be problem with X/driver, but on 11.2 with GNOME and Compiz everything worked great with no problems. Greetings.

Could you attach the output of 'hwinfo --gfxcard'? Thanks.

Honestly, with 855GM you can be happy if video output and 2D acceleration work. :-(

Why you think lilke that? I have been using OpenSUSE (SUSE) and Ubuntu for about 5 years on this hardware and there was NO problems with 3d support on 855GM. Compiz worked perfectly even on OpenSUSE 11.2... there were some changes in api/abi of kernel? I though that this is problem with KWin, but I am suprised that's problem with drivers or X.org and there is no solution...

Well the intel driver has been rewritten (using KMS now) as you might know and guess what, the newer chips have much more priority for Intel developers than the older ones like 855GM. We have various reports where not output is detected at all
on 855GM/915GM with the new shiny KMS-based intel driver ...

One option would be to try "intellegacy" driver (/etc/X11/xorg.conf.d/50-device.conf), but I believe in your case Mesa/libdrm or Kernel DRM driver is the culprit here.

Oh, I see... I didn't know about new version of intel driver. Thanks a lot for help and piece of both information and knowledge. I downloaded 11.3 milestone7 so after upgrade I will try to make more tests and to report every problem which is not reported. Regards!

I believe it would be worth a try to update to latest Mesa, libdrm and 
xorg-x11-driver-video packages from obs://X11:XOrg.

I have the same exact card in my Thinkpad X40 and am experiencing the exact same problems.  KDE4 Kwin effects worked perfectly in openSUSE 11.2 but not in openSUSE 11.3.

I decided to try using "intellegacy" driver in the 50-device.conf file and it worked!  Now I can enable desktop effects and there is no issue, even with suspend.  

Because using "intellegacy" driver worked, that means there is something wrong with the new driver.  A quick Google search shows that many distros suffer from this so this isn't an openSUSE issue.  How do we submit or check for a bug submitted upstream?

Also, what is the difference between the new driver and intellegacy ?  Since it is a laptop, does anyone know if there is any performance or battery life increases with using the new driver?  If so, I'll forgo the desktop effects for better performance (I know that there is better performance without desktop effects in general).

Mateusz, still waiting for a response for more than 3 weeks now. Please reopen once you can provide the requested feedback. Thanks.

Hello,

Sorry for long time with no response. So lets go with this - I have 3 notebooks with Intel graphic card (from 855MG to newer GMA chipsets) - all my notebooks are suffering from problems with Intel drivers - on 2 from 3 laptops on Compozition 3d mode (for ex. KWin) OpenSUSE 11.3 is often freezing to death sometimes even playing in 3d games. On ACER with 855GM there are additional problems with artefacts. 

The solution for all is as I wrote on official Polish SUSE Wiki: 
a) set NO_KMS_IN_INITRD="yes" in /etc/sysconfig/kernel file (or from YaST -> /etc/sysconfig editor). 
b) as Anthony Simonelli wrote we can change driver to "intellegacy" 
c) reboot X server - but better "for sure" to reboot system (I still have it after using Windows :P )

After that everything even with KWin seems to be OK. 

I don't like to wait - but I think I have to wait for new drivers - me, my brother and other using OpenSUSE 11.3.

Bug is still present in new OpenSUSE and I hope this is last version of this distribution with such kinds of problems. I will try tomorrow with update like  Stefan Dirsch wrote. 

Greetings
Mateusz (Matthew)

Reopenning comment - sorry for that but I just forgot to do that when posting latest post.

I didn't even have to disable KMS to get it to work when I used the "intellegacy" driver.  Just setting that driver allowed me to enable Kwin effects so it seems purely as a driver issue to me.

I've tried upgrading the libdrm, mesa and xorg-x11-driver-video packages from the X11:Xorg repository and it didn't help.

Anthony: I know that :) I just have 3 notebooks with different Intel graphic chipsets - all are suffering and I wrote some kind of solution which gave good effects on all 3 notebooks. I didn't tried to just switch to Intellegacy driver without second operation with NO_KMS_IN_INITRD. 

greetings

Updating to libdrm, Mesa, xorg-x11-server and xorg-x11-driver-video 
of obs://X11:XOrg might be worth a try. Hope this update doesn't 
make your issues worse.

Still waiting for a response for at least a week. Please reopen once
you can provide the requested feedback. Thanks.
