[i945gme] enabling visual affects causes graphics glitches for netbook remix (Jaunty Beta)

[Daniel Beckham]

Binary package hint: compiz

Enabling visual effects under appearance preferences causes graphical glitches. Foreground windows disappear as well as the app bar. Moving the mouse across the screen will cause widgets and parts of the screen to appear. Tab swtiching to an app will usually redraw the screen correctly.

Using Ubuntu Jaunty Release 9.04
Hardware: Dell Mini 9
Graphics Card: 00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GME Express Integrated Graphics Controller [8086:27ae] (rev 03)

I can confirm that bug on my EEE PC 901 (945GME) with netbook remix (Jaunty Beta).

[bazookatooth (wesley-hall)]

Confirmed here as well w/ Dell Mini 9 .

Also, I would think that this issue would be much higher priority than it seems to be currently. This issue is going to be *the* issue in the netbook OS war if it isn't fixed *soon*.

[Neil J. Patel (njpatel)]

Removing UNR team from assignment, this isn't a UNR bug. It isn't a Compiz bug either, it just can't be done with the current Intel graphics drivers. You can try using the latest rendering engine by enabling UXA in xorg.conf, but that is it's own can of worms. This should be much better by karmic.

Is this bug a duplicate of https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/158415

Hi danbeck,

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 all,

I can confirm the same problem on my eee pc 900

The problem only occurs to me when using the netbook remix launcher. If I switch back to gnome everything seems to bee working fine.

[Morjgus (m-ullmann)]

I confirm this bug on Lenovo S10e for Jaunty UNR (final). I've attached the wanted files and output.

[Doug Holton (edtechdev)]

I saw this with an Acer Aspire One - trying to upgrade it from regular Ubuntu to UNR.

Perhaps some check could be run (graphics memory <= 8mb) and disable visual effects if you install the ubuntu-netbook-remix package.

The other problem is that now both nautilus and the UNR interface are running. I don't see any docs on how to upgrade from regular Ubuntu to UNR and have it be just as if you installed the UNR .img. (I saw the UNR wiki page)

(the UNR .img doesn't install on Acer Aspire One - it can't boot to an SDHC card and if you copy it to a USB flash drive it gives ErrNo 5 no matter what. I would request an ISO version of UNR too, that would have fixed the problem for me.)

[Bryce Harrington (bryce)]

We are moving to the UXA acceleration architecture for Karmic, and this bug needs to be re-tested to see if it still occurs there. Would you please install and test the 2.7.0 driver and reproduce the bug, and let us know ASAP? A PPA with a Jaunty version of this driver is available at: https://edge.launchpad.net/~ubuntu-x-swat/+archive/x-updates/, or you can update to Karmic and test that. Thanks ahead of time, and let us know either way.

[Omegamormegil (omegamormegil)]

I upgraded xserver-xorg-video-intel to 2.7.1 from the PPA and I can still reproduce the bug. I have exactly the same issue as described by the original reporter using the Jaunty UNR interface with desktop effects enabled on my Dell Mini 9.

I have an Acer Aspire One netbook with ubuntu 9.04 remix edition ΟS and when I open emerald i take this http://img297.imageshack.us/my.php?image=screenshotemeraldthemer.png

I tried installing the xserver-xorg-video-intel from your PPA, logged out then logged back in. Sadly, I could still produce the error same as the original poster. Attached is my lspci output

[Jeffrey Patrick Lui (punong-bisyonaryo)]

And here's my xorg log file

If it helps, I also have the following graphics card:

[Bryce Harrington (bryce)]

(==) intel(0): Using EXA for acceleration

It seems you're still testing against EXA, which is known to have graphical glitches (and no longer is supported upstream)

Please see if you can reproduce this using UXA. In your xorg.conf set Option "AccelMethod" "UXA" in your device section. If you can still reproduce, reopen the bug and attach your Xorg.0.log, and if possible a photo showing the corruption. Or alternatively, test it against Karmic Alpha-2 or newer.

[Omegamormegil (omegamormegil)]

This bug appears to be fixed in Karmic Alpha 2. I tested the the Live image, and I could set my desktop effects to Normal without any tearing. I took a screenshot while one of the transparent notification bubbles was on the screen for good measure.

[Omegamormegil (omegamormegil)]

Under Jaunty, setting Option "AccelMethod" "UXA" like you suggested does actually fix the tearing problem for me with xserver-xorg-video-intel 2.7.1, but the performance was absolutely awful. Performance running the Karmic Alpha 2 Live image was fantastic.

[Jeffrey Patrick Lui (punong-bisyonaryo)]

Where should I put the AccelMethod option if I don't have any "Device" section in my xorg?

[Jeffrey Patrick Lui (punong-bisyonaryo)]

Hi,

Request help on where to put the UXA if there is no Device section in my xorg.

Thanks!

[Bryce Harrington (bryce)]

Thanks for letting us know the issue is resolved.

[El Toozero (eltoozero)]

After running with the Intel Accelerated PPA, and adding the UXA acceleration option to xorg.conf, the tearing issue is resolved however the sluggish performance on the netbook-launcher happens, I have removed the acceleration line since.

I'm content to run without video acceleration until 9.10 is released.
