I've forwarded this bug upstream for you to https://bugs.freedesktop.org/show_bug.cgi?id=23387 - please subscribe yourself to this bug, in case they need further information or wish you to test something. Thanks ahead of time!

Also, I notice you have a lot of parameters set in your xorg.conf; it is possible one of them could be putting the driver in a state that causes the artifacts. Can you see if disabling one or some of them make the artifacts go away? In particular, I'm suspicious of using greedy migration since it often has been seen to cause corruption problems.

ok removed the options from Xorg.conf. It does not matter for the AccelMethod as I suspect the PPA ati driver is using EXA anyway. Now the corruption is less likely, but it is different one, mostly text font tearing.

Does

    Option "EXANoDownloadFromScreen"

work around the problem?

[Gytis Raciukaitis (noxxious)]

EXANoDownloadFromScreen only helped when no OpenGL app was runnning at least for the time I tested. Once I started Auteria (http://www.auteria.com)game in the window, the font tearing and artifacts started appearing again. Also the text inside the game is flickering.

A similar mechanism as for DownloadFromScreen is used for evicting buffer objects from VRAM, so this indicates that VRAM -> AGP transfers are generally unreliable on your system. One thing I notice in your dmesg is

[35162.662996] [drm] AGP mode requested: 4

Maybe you can try different values for the radeon.agpmode parameter, including 1, 2, not specifying any explicitly or -1 to disable AGP.

If none of that helps, maybe you can try booting the kernel or loading the radeon kernel module with radeon.test=1 and see if that gives any interesting results.

> Also the text inside the game is flickering.

That could be a separate issue.

[Gytis Raciukaitis (noxxious)]

using radeon.agpmode=1 and EXANoDownloadFromScreen still results in font tearing. I'll try with agpmode=-1 to be sure.

attaching dmesg with radeon.test = 1 output.

I cannot test for long as using EXA causes random hard freezes if EXANoComposite is not set.

dmesg log

[Gytis Raciukaitis (noxxious)]

Testing now with radeon.agpmode=-1 so far no tearing/artifacts or hard freezes with EXA running for 6 hours.

If the AGP transfers are borked, how come the fglrx driver worked with AGP 4x and why are both tearing and hard freezes only showing up with ati driver ?

[Gytis Raciukaitis (noxxious)]

hi,

following the recommendations on the other defect on freedesktop I have force the card into the PCI mode using the radeon driver option radeon.agpmode=-1 in karmic.

After that I'm running with no problems for one week.

Do we really need an AGP Quirk ?

[Stefan Nagy (stefan-nagy)]

I can confirm this bug (with another ATI card - see below). Forcing the card into PCI mode using the driver option 'radeon.agpmode=-1' is the only solution for me (even though performance suffers); I tried AGP modes 1, 2, 4 without any results; option 'EXANoDownloadFromScreen' didn't work for me either.

I was affected by bug #444139, so I used boot option 'radeon.modeset=1' to turn on KMS. Since then I'm affected by this bug. The only way to get rid of screen artifacts and font tearing (as shown by Gytis Raciukaitis) is boot option 'radeon.agpmode=-1'.

I attach the output of dmesg without option 'radeon.agpmode=-1'

I can also confirm this bug on an Radeon 9800 PRO AGP. Running the ddx from git, I would get massive corruption all over the screen, but putting the card in AGP mode with the kernel parameter proposed here makes it all go away.

I can also confirm this bug on a thinkpad T42 laptop running arch linux.

Grapics card (lspci):

Some random characters start to look very weird after some random time (2 minutes to several hours) of operation (see screenshots above)

[Olivier (olivier-lacroix)]

I got the same issue on Archlinux and solved it patching the kernel with a fedora patch. see http://<email address hidden>/msg44253.html

it is now working with KMS without any corruption.

Hope that helps

the location and the navgator bar are corrupted

The fonts used inside the epiphany are here okay yet. after quite some working with apps, the fonts get weird in xterm/gnome-terminal/browser.
But changing the fontsize (ctrl++) in browser or in the gnome-terminal dies help
until these font(sets) are also corrupted.

Are things any better with the radeon drm modules from drm-next?

> Are things any better with the radeon drm modules from drm-next?

I have compiled today the drm-2.6/drm-next branch (2.6.31-rc9) with my configs and I noticed no chars looks weird anymore (until now) xD

Than I have dumped all radeon regs,lspci, dmesg and suspended to disk from Xorg.
The resume fails here after the message "Loading Console Fonts [OK]"

When I s2disk at the console with a running xorg and resume, the resume and teh boot are okay, but I cannot get into a working Xorg as with the 2.6.32-rc6 (resume comes up with different IB schedule errors, restarting Xorg does not help, the schedule fails -> https://bugs.freedesktop.org/show_bug.cgi?id=23103 will post there my logs in a few minutes).

Since today I have also merged linux-2.6
commit 6b46362c0ea472b174c336786fd406c504326ad4

And one good message from today: I have to mention that I do not detect the weird chars in 2.6.32-rc6 anymore, too. I will stress testing some apps on the desktop now.

Is this still an issue on a newer kernel from lucid or http://kernel.ubuntu.com/~kernel-ppa/mainline/ ?

[bjaglin (bjaglin)]

I had the problem in 2.6.31, but I can't reproduce it in 2.6.32, so I guess this should be closed.

[Minimec (minimec)]

As I am also affected by this bug with that same ATI Radeon 9600 Mobility, I would like to add some experiences I made with kms and the 9.10 kernel.

After multiple karmic installations with ATI GPU's, I was surprised to see this bug with my ATI Radeon 9600 Mobility. I also suffered from performance problems with that Radeon 9600 Mobility without kms enabled (regression 9.04 --> 9.10).

Following the advice posted here I get best performance using kms and forcing the card in pci mode.

My card setup is done via a radeon.conf in /etc/modprobe.d/ with the following two lines:

options radeon agpmode=-1
options radeon modeset=1

(Don't forget to run 'sudo update-initramfs -u -k all' after you made the changes.)

Other ATI devices like the FireGL V3200 Mobility (IBM ThinkPad T43p) or even a normal Radeon 9600 (Desktop computer) are not affected by this bug. I would rather say that I have some quiet decent performance with these cards (kms enabled). A little bit more problems with my ATI x1250, but the performance of the x1250 is getting better and better too, and the card is not affected by this bug...

Following the advice posted in this bug I get best performance using kms and forcing the card in pci mode.

Don't forget to run 'sudo update-initramfs -u -k all' after you made the changes.

Kudos to all the people that work on the new ATI driver, as the OpenSource driver generally performs better than the fglrx driver ever did, when I used it on that HP/Compaq nc8000... ;)

I can confirm that - since I installed lucid's kernel (linux-image-2.6.32-13-386) the screen artifacts disappeared (& KMS is enabled by default). Besides, the performance of my ATI card is really amazing now... It's like I got a new notebook :) Thanks!!
