[RV350 9600] suspend causes corrupt window decoration

[jcdutton]

Graphics card:
01:00.0 VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]

To reproduce the problem:
With compiz enabled in intrepid (Ubuntu 8.10).
Suspend to RAM.
Restore from RAM.
All the window decoration is corrupted.

To workaround the problem:
Go into compiz settings, untick "window decoration", retick "window decoration". The window decoration is then OK again, until the next suspend to RAM.

Description: X.Org X server -- ATI Radeon display driver
 This driver for the X.Org X server (see xserver-xorg for a further description)
 provides support for the ATI Radeon and FireGL series. It provides the 'radeon'
 driver.
 .
 Note that this is not the same as the ATI-provided, binary-only, 'fglrx'
 driver, which provides additional 3D functionality for some newer Radeon
 cards, but is not supported.

 This driver provides support for Radeon and FireGL series ATI cards.

Your issue seems to be related to Bug #90740.

follow link:

https://launchpad.net/ubuntu/intrepid/hppa/xserver-xorg-video-radeon/1:6.9.0+git20081003.f9826a56-0ubuntu2.1

and download the .deb under Downloadable Files:
 xserver-xorg-video-radeon_6.9.0+git20081003.f9826a56-0ubuntu2.1_hppa.deb

[jcdutton (james-superbug)]

I have i386 and not hppa CPU so it will not install.

[jcdutton (james-superbug)]

Managed to find and install the i386 version.
Window decorations are still corrupted after resume.

[jcdutton (james-superbug)]

I think the problem is not so bad as it was.
The individual windows seem to be OK now, the problem remains with the "root" window. I.e. The desktop has the top line (where a windows decoration might be) corrupted.
Toggling the compiz decoration fixes the problem.

[Bryce Harrington (bryce)]

Thanks for testing that jc, I think we can forward this bug upstream but need a bit more information first, that upstream requires.

Can you please attach your /var/log/Xorg.0.log while running with the newer driver, and then run `lspci -vvnn > lspci.txt` and `lshal > lshal.txt` and attach both of those files? Thanks.

Also, if you have a digital camera, attaching a photo of the screen couldn't hurt (I think the description is clear enough though, if this is difficult.)

[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. In your /etc/X11/xorg.conf set AGPMode to various values like this:

 Section "Device"
      ...
      Option "AGPMode" "2"
 EndSection

Possible values include 1, 2, 4, 8. You can see what it's currently set to by looking in /var/log/Xorg.0.log. It's worthwhile to test all four values even once you find one that works. If this takes care of it for you, we may be able to establish a quirk to set it for your hardware combo

For more details on this, please see the "ATI AGP Mode Quirk" section at https://wiki.ubuntu.com/X/Quirks

[jcdutton (james-superbug)]

Regarding AGPMode
The linux driver defaults to using 4x.
Under windows, the setting used is 4x.
I have tried 1x and 2x in Linux but neither help.

[jcdutton (james-superbug)]

Another symptom:
When the corruption happens I do the following steps:
1) I press ALT-F1 to switch to the dumb terminal screen but it has no display at all.
2) I press ALT-F7 to switch back to X terminal screen and the corruptions have been removed.
3) I press ALT-F1 to switch to the dumb terminal screen and it displays as normal.

My conclusion to this is that when suspending, the full state of the graphics card is not being saved.

[Bryce Harrington (bryce)]

I notice from your last posted log that you tested against hardy. Could you please re-verify this bug still exists in Jaunty? You can get an ISO image from http://cdimages.ubuntu.com/releases/jaunty/. If you install Alpha-4 make sure to apply the latest updates so you test against -ati version 6.11.0. Thanks ahead of time.

[jcdutton (james-superbug)]

Testing from ISO image is not easy for me for various reasons.
Any chance of back porting the fix to intrepid or providing a .deb for me to try.

[Bryce Harrington (bryce)]

Oh nevermind actually -- I notice you're using XAA (the default for Intrepid), which had several known corruption/artifact issues esp. relating to suspend/resume. These issues go away when using AccelMethod EXA; there were some performance regressions with EXA on Intrepid which is why we didn't move to it. We use EXA as the default on Jaunty now, and don't see the performance issues.

So I'm not sure what you'd find testing the newer drivers on Intrepid, but the problem should be gone on Jaunty so I'm closing the bug.

[jcdutton (james-superbug)]

You are correct. EXA on the normal Intrepid drivers has major performance issues. I.e. Pauses while scrolling an xterm window.
Would EXA work better on intrepid using the backported driver you mention?

[jcdutton (james-superbug)]

I have installed Jaunty on the Laptop.
EXA has the same performance problems as Intrepid. Pauses while using xterm, Xorg taking more CPU.
So, I am currently back to using XAA on Jaunty.
XAA on Jaunty still has the same suspend problems as it did on Intrepid.

[This is an automatic notification.]

A new version of the -ati driver is now available in Karmic.

This is a significant update to -ati which brings in kernel mode-setting
(currently disabled) and scores of fixes for DRI2, EXA, etc.

I've posted the new version of this driver to the following PPA,
would you mind testing it and seeing if it resolves the bug you
reported?

  https://edge.launchpad.net/~bryceharrington/+archive/ppa/+sourcepub/709908/+listing-archive-extra

If you're not running this release of Ubuntu, you can try booting the Karmic
LiveCD and loading the PPA onto it, and then log out/in to restart X.
ISOs are available at http://cdimages.ubuntu.com/releases/

After testing Karmic, report back here whether it's still an issue or not,
and if it is please post a fresh Xorg.0.log and 'dmesg' output.

Note there could be new bugs... please file these as new reports using
the command 'ubuntu-bug xorg'.

[jcdutton (james-superbug)]

Problem still present.
Only reproducable with compiz running.

[jcdutton (james-superbug)]

I do not seem to be able to reproduce the problem with latest karmic update.

[Bryce Harrington (bryce)]

Thanks for letting us know the issue is resolved.
