[Wolfgang Griech <wolfgang.griech@xxxxxxxxxxxxxx>]

I'm seeing this problem too, since I moved from Kubuntu 8.04 to 9.10.
HW: Fujitsu Siemens Lifebook E4010D and a intel 955 GPU, all the latest
patches for xorg and kde loaded, also from PPA. Kernel 2.6.31-20, but
same problems from on -14. KDE 4.4.1, xserver-xorg-video-intel -
2:2.9.01-1. Basically 3 types of graphics errors with different severity
and effects:

the little tabs or hints with detailed info from the task bar don't
always show up at the right place, and don't always get removed right. A
bit annoying, but not too serious. One way to reproduce: left click on
the network manager icon after bootup, the info shows up in the top left
corner of the screen. Right click on the icon, info directly next to it,
left click from from on then on the same. Every other effects alike are
random, couldn't find a way to reproduce.

video from a webcam (Logitech C300) on skype or cheese never worked for
me on 9.10. No streaming of any video data in anyone of the 2 apps, but
mplayer worked fine! I almost gave up on this, but the latest xorg intel
driver update around the frame buffer alignment bug made it happen, and
everything perfectly works now, thx!

the third bug is about the one mentioned everywhere above, a complete
lockup of the screen, randomly, maybe 2 days in a row fine, then 3 times
a day. Always in conjunction with some heavier graphics activities, like
opening some new windows, selecting a bigger text etc., and only a
complete shutdown helps. I'm still not that deep into all the tools, but
after such a lockup we still can get onto the laptop with ssh, and I
think it was ksysguard showing the "i915_gem_retire_work_handler" status
for the i915 driver. This bug is extremely annoying, and I've lost quite
some work due to it already..

OK, a few days ago I found just by coincidence the 100% killer for my
system, it's Google Earth, the latest downloadable version. Just start,
and within a few seconds my laptop graphics is dead. Perfectly works on
another system with all the same os and graphics versions as on my
laptop, but with a ATI radeon GPU, could verify this today, so it's not
like I thought a bug in Google Earth, but apparently in the graphics
driver.

this other PC also doesn't experience the lockups, and never did so. But
it had this "hints location" problem too, which disappeared since we've
changed in the BIOS (!!!) the default settings for the graphics card
from PCI to PCIe, which it really is.

sorry if I messed up a little bit here and maybe put too many things
into this thread, but I think most or all of the bugs are clearly
related and come down just to the intel i915 xorg driver.

could anybody with more linux knowledge than me please verify the Google
Earth i915 killer, and publish the appropriate info, or tell me what
exactly to do in order to provide the necessary info.

TIA
