[gm45] 3D image image ghosting

Sony VAIO VGN-FW140E/H notebook with Intel Mobil Series 4 chipset.
Centrino 2, 3GB RAM, 1600X900 display with "Full HD 1080p"
I am running the 2.6.30 kernel and the launchpadpaa intel video enhancements steps which utilize the UAX mode. Here is my entire xorg.conf file, which includes the modifications suggested by the "bleeding edge" configuation. These enhancements increased my fps in SecondLife from and average of 4fps to an average of 25fps.

Most applications which use accelerated video work fine: GoogleEarth, Tux Racer, LinCity-NG, Stellarium, gl-117, FlightSim, Pinballs, Billard-gl and foobillards.

SecondLife works well, except when I take a screen snapshot or attempt to edit the avatar. Any editing in SecondLife is impossible because the image is too distorted. The screen snapshot of my avatar in SecondLife shows the problem and I have attached a pgn file of it.

TORCS runs, but the image is garbled in the same way my SL avatar image is.

Penumbra's three Linux role playing games are unusable. Their introductions work fine, but when in the tutorial mode trying to learn how to grab objects or move them the images are similar to my SL avatar snapshot, only worse. In the actual game mode the scenes are indecipherable so the games are unplayable.

lspci -vvnn gives:

Hi greygeek,

Thanks for including an image to demonstrate the issue. Could you also please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log or Xorg.0.log.old file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hi Bryce!
The output of "lspci -vvnn" is already in my original report, as is the
xorg.conf contents.
I have attached /var/log/xorg.0.log to this email, along with
xorg.conf. I attached these right after running SecondLife and taking
another snapshot to disk. It is 10:33PM CST but the timestamp on
xorg.log is 9:05PM CST. In other words, taking the snapshot did not
trigger any additions to the xorg log file.

The entire snapshot is only 1.4MB. If that is not too big for your
email service do you want me to send it?

“They’ll get sort of addicted, and then we’ll somehow figure out how to collect sometime in the next decade.”

–Bill Gates

“Bill Gates looks at everything as something that should be his. He acts in any way he can to make it his. It can be an idea, market share, or a contract. There is not an ounce of conscientiousness or compassion in him. The notion of fairness means nothing to him. The only thing he understands is leverage.”

–Philippe Kahn

I don't think it's any coincidence that Microsoft achieved dominance in the American market during the same period that bottled water became omnipresent. In both instances, clever marketing convinced the general public that something that was clean, safe and free was inferior to a product encased in plastic.

Attached is the entire image of the SecondLife snapshot to disk. Although SecondLife plays fine and I get up to 35 fps, depending on what I am doing, other applications which use 3D acceleration give screen images which look exactly like the SecondLife snapshot to disk, making them impossible to play, as I pointed out in my orginal post.

I've attached the entire SecondLife snapshot to disk to show you what the entire screen looks like.

Another anomoly has appeared on my SecondLife screen.

Also, a sold black line about 1/2" wide at about 3/4" from the right margin of my 100X900 display, began appearing. First it was light grey and somewhat transparent, but eventually it got solid black. Strangely, other objects could appear on top of it and they would cover it. Other 3D accelerated programs, like Stellarium, do not exhibit that black line. Only SecondLife.

Xorg.log (via dmesg) gave the following:

[ 6054.721593] [drm:i915_gem_evict_something] *ERROR* inactive empty 1 request empty 1 flushing empty 1
[ 6070.956792] [drm:i915_gem_object_bind_to_gtt] *ERROR* GTT full, but LRU list empty

preceded the breaking of the xserver, causing it to reboot as if I had pressed Ctl+Alt+Bkspc

Bryce,
I have been experimenting with 64bit Ubuntu 9.10 Alpha4 and 64bit Kubuntu 9.10 Alpha4.

Both give excellent 3D acceleration without using the PPA "bleeding edge" patches, etc...

AND, both give good snapshots and good avatar images while editing the appearance of the Avatar.

Since I am moving to the 64bit Kubuntu 9.10 when it is released the graphic problem on the 32bit Kubuntu 9.4 will be moot.

Okay, sounds good. Thanks for letting us know the issue is resolved in Karmic, we can consider that the solution.
