[R350] screen corruption on 9800SE

[SlimJim]

Binary package hint: xserver-xorg-video-ati

There seems to be a problem with the Ubuntu ATI driver and my ATI Radeon 9800 SE card. When I boot Ubuntu 9.10 (installed on HDD) or Ubuntu 10.04 (beta 2 from CD) certain elements of the desktop contain artifacts (see screenshot "visual_effects_disabled.png"). If I enable in System > Appearance > Visual Effects the amount of artifacts increases dramatically and cover the desktop completely (see screenshot "visual_effects_enabled.png").

This is what lspci tells me:
01:00.0 VGA compatible controller: ATI Technologies Inc R350 AH [Radeon 9800]
01:00.1 Display controller: ATI Technologies Inc Radeon R350 [Radeon 9800] (Secondary)

I'm happy to assist further investigations!

[Tormod Volden (tormodvolden)]

Thanks, that's very good.

[Tormod Volden (tormodvolden)]

More out of curiousity, which version of 9800SE do you have? Can you recognize the card on these pictures: http://www.digital-daily.com/video/ati-radeon9800se/

[Tormod Volden (tormodvolden)]

These SE cards have only one quadpipe AFAIK, but 2 are detected by the drm:
[drm] radeon: 2 quad pipes, 1 Z pipes initialized.

Can you please reattach the Xorg.0.log and dmesg from 9.10?

[Tormod Volden (tormodvolden)]

Can you please try the 10.04 live CD, there install the packages from https://edge.launchpad.net/~xorg-edgers/+archive/radeon
(at least the libgl1-mesa-dri package) and log out and in again?

This is to verify a possible fix I am working on, so in the first case you should see the same issue with these packages. Later I will post updated packages with the fix and we can compare.

[Tormod Volden (tormodvolden)]

BTW, this should eventually be fixed in the kernel, and I have a patch ready for it, but it is much easier to patch and test the mesa drivers instead, especially on a live CD...

[Tormod Volden (tormodvolden)]

Now, 7.9.0~git20100416+gallium+r300.f91a06ee-0ubuntu0tormod does not have the fix, but 7.9.0~git20100418+gallium+r300.0490116f-0ubuntu0tormod will have the fix to test. If you don't see these versions in the PPA, choose "Any status" in the search filter.

[SlimJim (tobias-dh1tw)]

I checked the pictures on http://www.digital-daily.com/video/ati-radeon9800se/ against the card I have in my PC. I do have a card based which seems to be based on the Radeon 9500 Pro design.

[SlimJim (tobias-dh1tw)]

I set up the PPA and installed the 7.9.0~git20100418+gallium+r300.0490116f-0ubuntu0tormod version on the Ubuntu 10.04 beta2 liveCD. I logged out and again in. Unfortunately, it does not solve the problem. I purged the PPA and reinstalled it a second time, but without any effects.

[Tormod Volden (tormodvolden)]

Hmm, maybe my hypothesis is wrong. However, these test packages from the PPA use gallium drivers as default instead of the classic drivers, and I am less confident about my fix for gallium, so please test classic this way:
After installing the packages:
 cd /usr/lib/
 sudo mv dri dri-gallium
 sudo mv dri-classic dri
and then log out and in again.

[SlimJim (tobias-dh1tw)]

Okay, I will give it a try when I return to home this evening.
Thanks

[SlimJim (tobias-dh1tw)]

I installed the 7.9.0~git20100418+gallium+r300.0490116f-0ubuntu0tormod version on the Ubuntu 10.04 beta2 LiveCD from the PPA. After installing the packages from PPA I executed these commands:
   cd /usr/lib/
   sudo mv dri dri-gallium
   sudo mv dri-classic dri
logout & login

Unfortunately nothing has changed. The entire screen is still overlayed by artifacts.
Any more ideas? Was there anything I could have done wrong?

[Tormod Volden (tormodvolden)]

It sounds like you did it right, so I am not sure my fix makes any difference for you. The fix for gallium was definitely wrong, but I have uploaded a better version in today's PPA packages.

Can you please instead (in 10.04) copy this file to /usr/lib/dri and after logout/login, run this to verify that the new file is in use:
 glxinfo > /dev/null
It should list the number of (quad)pipes detected.

[SlimJim (tobias-dh1tw)]

Somehow the ppa repository doesn't deliver the new version. It's still the 7.9.0~git20100418+gallium+r300.0490116f-0ubuntu0tormod one. Is there a way to force the ppa to download the new (419 built) ?

[SlimJim (tobias-dh1tw)]

Somehow purging and reinstalling the ppa did the job. Now I have installed your new built 7.9.0~git20100419+gallium+r300.7dfde3aa-0ubuntu0tormod on the freshly rebooted Ubuntu 10.04 beta 2 LiveCD.

This is the output of glxinfo > /dev/null

[Tormod Volden (tormodvolden)]

I meant, just copy the file, without installing from PPA. Anyway, the number of fp pipes is now 1 which should be "safe" for these cards. If you still have corruption, there must be another reason for it.

Some of these cards have only one functional pipe, or one that passed the tests at the fab, so they disabled the second in the window driver and spec'ed with 1 and called it "SE". Then this series got so popular that they continued shipping it like that even if the cards actually had two perfect pipes. The linux drivers run all cards with 2 pipes, so I thought that was the problem. But you are maybe one of the lucky ones with two working pipes. And the corruption is due to something else.

[SlimJim (tobias-dh1tw)]

Thanks for your help in investigating the problem. Somehow I'm still not sure where the problem lies. On WindowsXP the card works just perfectly and is recognized without any problems by ATI driver / ATI Cataylst. Yesterday I went back to my Ubuntu 9.10 installation and tried to install the proprietary ATI fglrx driver, but it was not possible. Linux ATI catalyst doesn't recognize the card. As a result of removing the ati ragoen driver and not being able to install fglrx the artifacts disappeared on the screen. However it's painful slow and I assume Ubuntu is using some kind of generic driver which doesn't use the 9800SE hardware at all.
It almost impossible to watch a video on youtube or similar stuff which would makes use of the graphic card.

Do you have any other ideas what could be the problem? Is there anything I could do to further investigate the problem?

Thanks, your help is really appreciated!

[Tormod Volden (tormodvolden)]

Yes, if you do not remove fglrx properly, it will keep the ati radeon from running with hardware accelerated 3D. With no acceleration you won't get the corruption, which only was visible when acceleration was in use (compiz and 3D apps). See
https://wiki.ubuntu.com/X/Troubleshooting/FglrxInteferesWithRadeonDriver

[SlimJim (tobias-dh1tw)]

Yes, this is understood. However the artifacts appear when the radeon driver installed. Even with having the Acceleration disabled (System > Preferences > Appearance > Visual Effects > None) the screen has some artifacts (see screenshot visual-effects-disabled.png). However they don't cover the whole screen.
I suppose, I need to buy another graphic card for this computer in order to use it properly with Ubuntu.
Thanks again for your attempts fixing the problem.

[Tormod Volden (tormodvolden)]

Even without Visual Effects, the radeon driver uses acceleration on the card (EXA, composite etc), so some corruption can be seen. This acceleration is not used if fglrx is blocking, or if you are using the vesa driver ("failsafe").

With compiz it will use hw acceleration for the whole screen, that's why you see it all over.

Did you have any corruption with an older version using fglrx? If not, there is probably a bug in the ati radeon driver. If you did not see corruption in older releases with ati radeon, it could be because it did not use much hw acceleration features at the time.

[Tormod Volden (tormodvolden)]

Can you try turning off RenderAccel, as suggested here: http://www.ubuntu.com/getubuntu/releasenotes/1004

[SlimJim (tobias-dh1tw)]

Thanks for the explanation! I tried to disable RenderAccel but X seems to dislike it and only allows startup in Low Graphics mode. Well, finally I'll visit my local PC shop and purchase another graphic board. Those old AGP cards aren't expensive anymore.
Please sent me in a private message your paypal email so that I can pay you at least a beer! Thanks a lot for your help and your willingness to help me with this problem!

[Bryce Harrington (bryce)]

Based on the description of the symptoms, it sort of sounds like this might be caused by an incorrect AGPMode setting, which is relevant when DRI is enabled. You should test if changing this makes the issue go away.

For KMS configurations, agpmode is a kernel module parameter. Enter the grub interface during boot and append radeon.agpmode=X to the kernel boot line, where X = -1,1,2,4,8

1-8 are the agp modes,
-1 uses the onboard gpu gart (PCI, PCIE, etc.)

For details about this with UMS (non-KMS), please see the "ATI AGP Mode Quirk" section at https://wiki.ubuntu.com/X/Quirks

[Tormod Volden (tormodvolden)]

Right, I was too obsessed by the pipe numbers to think about this classic issue. Slimjim, your card runs with 8x out of the box, so please try 4x (the only other option for these AGP v3 cards): radeon.agpmode=4

[SlimJim (tobias-dh1tw)]

Hey Bryce and Tormod, thanks for the advice. I did so and included radeon.agpmode=4 as a boot parameter, but it has no effect. I even included it as a fixed boot parameter in /etc/default/grub as GRUB_CMDLINE_LINUX_DEFAULT="radeon.agpmode=4"
GRUB_CMDLINE_LINUX="radeon.agpmode=4" but without success. I'll just buy me a new AGP card tomorrow. Thanks again so much for your help!

[Tormod Volden (tormodvolden)]

We still want to fix your old card :) Actually I found out now that the pipe number mismatch has to be fixed in the kernel as well as the Xorg driver. With the wrong number here, the corruption that you see is mighty possible.

This has now been fixed upstream, and the fixes are good candidates for a SRU in Ubuntu 10.04. So even if you buy I new card, it would be great if you could try test packages and verify that they fix your problems.

[Bryce Harrington (bryce)]

Hi SlimJim, if I read your comment correctly, you are not interested in pursuing this bug further? If that's the case could you set the bug report to Invalid?

If you're interested in continuing doing testing and troubleshooting, the next step is to send the bug report upstream, and they'll probably suggest additional things to test.

[Tormod Volden (tormodvolden)]

I have uploaded a test package for xserver-xorg-video-ati in https://launchpad.net/~xorg-edgers/+archive/drivers-only
Please try it, although I am not sure if the kernel must be fixed as well for you to see a difference.

Reference to kernel patch: http://lists.freedesktop.org/archives/dri-devel/2010-April/000214.html

[SlimJim (tobias-dh1tw)]

Ok - no problem. I will postpone the purchase of the new card and keep on investigating together with you guys. I set up the PPA in my Ubuntu 9.10 to https://launchpad.net/~xorg-edgers/+archive/drivers-only but apt-get does not retrieve the latest version. Maybe it takes some time until the repository is updated. I left the radeon.apgmode=4 in /etc/default/grub. In case I should remove it, please advice. Tomorrow I'll try again to install your patched version 1:6.13.99~git20100422.1ad41054-0ubuntu0tormod.

[SlimJim (tobias-dh1tw)]

Guys, how do I tell apt-get to download the latest xserver-xorg-video-ati driver (1:6.13.99~git20100422.1ad41054-0ubuntu0tormod) ? Whatever I do (install, purge, update, upgrade) my Ubuntu 9.10 does not want to download the latest version. It only uses xserver-xorg-video-ati driver 1:6.12.99+git20091125.0061c4db-0ubuntu0tormod2

[Tormod Volden (tormodvolden)]

The newest version is only for lucid. I will have to update the karmic version if you want to test in karmic. Anyway, we can wait a few days for the new kernel release which hopefully will have my fix included.

[SlimJim (tobias-dh1tw)]

Okay, just booted again the Ubuntu 10.04 beta 2 Live-CD. I fetched 1:6.13.99~git20100422.1ad41054-0ubuntu0tormod from the ppa archive, logged out and and again in. Unfortunately, there are no changes. The screen is still cluttered with exactly the sam artifact pattern.
Will the change in the kernel have additional effects?

[Tormod Volden (tormodvolden)]

The fix is now in Linus' kernel tree, and should be in today's snapshot here: http://kernel.ubuntu.com/~kernel-ppa/mainline/daily/2010-04-28-lucid/ You can install this kernel in your Karmic system to try out (unless you have a Lucid system). The updated -ati driver for Karmic in https://launchpad.net/~xorg-edgers/+archive/drivers-only has been uploaded, but wait for the -tormod3 version to be built. The mesa packages from https://launchpad.net/~xorg-edgers/+archive/radeon are for lucid and I don't know if they can be installed in a Karmic system. so try first without. But to fix the corruption in all situations, all three packages must be updated.

[Eugenio123 (diagosta-e)]

hi guys! i think that i have the same problems even with lucid linx now and before with Karmic.. desperation! :(

I updated today my system to Lucid. After the update I performed the following actions:
1. installed the kernel you recommended (linux-image-2.6.34-999-generic_2.6.34-999.201004281008_i386.deb)
2. install the ati driver (1:6.13.99~git20100422.1ad41054-0ubuntu0tormod) (what do I have to do to install tormod3 version?)
3. install mesa package (7.9.0~git20100429+gallium+r300.f7cf8b46-0ubuntu0tormod)

Now, the artifacts are gone, but acceleration (System > Preferences > Appearance > Visual Effects > Normal) still doesn't work. I'm not sure if the current system is really using the ati driver. How can I verify if the system is really using the ati driver?

Thanks

[Tormod Volden (tormodvolden)]

Sounds like you have got the right packages (the -tormod3 version was for Karmic). Can you please attach dmesg and glxinfo output and your Xorg.0.log? With that mesa package (+gallium), please try as I described in comment 53 to use classic drivers.

The kernel looks good (dmesg), but you must have got the mesa packages messed up. Please try reinstalling the normal ones, then try again. I am running Lucid with kernel 2.6.34-020634rc6-generic and mesa packages 7.9.0~git20100429+gallium+r300.f7cf8b46-0ubuntu0tormod (from radeon ppa) and ati/radeon 1:6.13.99~git20100422.1ad41054-0ubuntu0tormod (from drivers-only ppa) and both classic and gallium work fine.

[SlimJim (tobias-dh1tw)]

Okay - I reinstalled the mesa package as instructed.
I also renamed the dri folders as requestes in #53

Compiz still does not work, however as mentioned the artifacts have disappeared.
Find attached the logs

[Tormod Volden (tormodvolden)]

It is strange, because the dmesg confirms that the radeon kernel module is loaded and KMS is initialized, but the Xorg log indicates that the module was not loaded in time. Can you please try booting with "text" as an extra boot parameter, then log in on the console and start X with "startx"?

[SlimJim (tobias-dh1tw)]

I did so. Find attached the Xorg.0.log

Still can't enable compiz.

[SlimJim (tobias-dh1tw)]

This is the syslog. In case you might find some useful informations in it.

[Tormod Volden (tormodvolden)]

It seems like you are now hit by another, unrelated bug. Can you please revert to the standard Lucid packages and see if everything is fine (except the original corruptions of course). Only then can we move on, step by step with our test packages.

[SlimJim (tobias-dh1tw)]

Okay - I purged the ppa:xorg-edgers/radeon and ppa:xorg-edgers/drivers-only and reinstalled the standard drivers.
I'm using now again Kernel 2.6.32-22-generic. Can't see any artifacts but the 3D acceleration doesn't seem to work.
Find attached my logs.

[SlimJim (tobias-dh1tw)]

So currently while having downgraded to the standard lucid packages I can't see any difference to our tests performed on the development kernel and your test packages. It's exactly the same behaviour - No more artifacts but also 3D acceleration (e.g. enabling compiz) doesn't work

[SlimJim (tobias-dh1tw)]

Sorry - please disregard Comment #97. After rebooting I have now again the artifacts (probably as it should be)

[Tormod Volden (tormodvolden)]

Good, start with only upgrading the kernel and see if 3D acceleration is still working.

[SlimJim (tobias-dh1tw)]

Today I finally have given up. I went to the local PC store and got a new Graphic Card. It's already installed and everything works as expected. I hope we could at least verify the patch you have written successfully. If you don't mind I would close this bug report. Thank you again so much for your help! I still you like to buy you a beer!

[Tormod Volden (tormodvolden)]

OK, maybe at a later point you can try the old card again and verify everything works in a Ubuntu 10.10 alpha release. Anyway, thanks to your bug report this got fixed and I guess there are many Linux users on 9800 SE out there who will appreciate it.
