color corruption with openchrome on Fujitsu Siemens Amilo Pro V2030

[Rüdiger Kupper]

After update to Lubuntu 12.10, I experience color corruption with the openchrome driver on my Fujitsu Siemens Amilo Pro V2030 notebook.
From the Xorg log I see that the driver correctly loads and identifies my notebook as Amilo Pro V2030. However, I see color corruption on the graphics screen (see attached screenshot):
All contents of the screen are displayed, but screen is typically divided into three horizontal stripes, tinted cyan, red, cyan. Sometimes there are no stripes, but a ghost image of the last screen before reboot, in cyan/red.
The mouse pointer is a red square.

Attaching Xorg.0.log.
Please tell me what else you need.

Forcing vesa driver in xorg.conf yields correct, but slow display.

News:
1. Booting from Lubuntu 12.10 live CD: Same problem.
2. Clean install from this very Lubuntu 12.10 live CD: Problem is gone.

In a clean installation of Lubuntu 12.10, the openchrome driver works well. I cannot see a difference to my previous installation (which previously was Ubuntu, then package ubuntu-desktop removed, and lubuntu-desktop installed).

One thought though: My old installation had GRUB 1, which never got replaced during updates. The new installation has GRUB 2. Perhaps this does a better job initializing the graphics

Still, graphics are corrupted when booting the live CD, indicating there is a problem to be solved.

Hi, since updating openchrome on my Amilo Pro V2030 (running EL 6.4) to version 0.3.0-3.20120806git, image corruption appears. I have also tried the latest version from git, which did not fix the issue.
Xorg.0.log and picture are attached.

RHEL 6.4 (and clones) are using an openchrome snapshot between 0.3.0 and 0.3.1. RHEL 6.3 and earlier were using 0.2.904, this is a huge gap.
It would be nice if you can bisect the regression or at least try 0.2.905 and 0.2.906.
Also, can you please provide the X log from 0.3.2 (which is at this point similar to git master) ?

[magilus (magilus)]

hi, builds of 0.2.905 and 0.2.906 fail because of:
via_accel.c:37:22: error: xaalocal.h: No such file or directory

it seems as if the current version of xorg-x11-server-devel-1.13.0-11.sl6.i686 does not include xaalocal.h anymore. any help on building it anyway is much appreciated.

[Xavier-3a (xavier-3a)]

XAA has been removed from X server 1.13, that's why 0.2.905 and 0.2.906 are not building. It might be possible to backport some fixes to allow building without XAA, I'll try to take a look.

Meanwhile, can you try to run 0.3.2 without 2D acceleration ? You need to use Option "NoAccel" in your X configuration.

[magilus (magilus)]

NoAccel does not solve the problem.

So, I've now compiled a KMS kernel based on those instructions: http://www.freedesktop.org/wiki/Openchrome/TtmGemKms

Does not work, image corruption (different now) still appears.

I'll attach logs regarding this issue.

heres the picture belonging to the issue.
the cursor corruption can be probably solved by using swcursor

besides of that, colors are unreal (too much blue, too much red), there's a little bit of image corruption in the middle of the background and sometimes there also was a translucent scientific logo in the middle everywhere.

I just realized that you can even take normal screenshots of the issue. I found it interesting that you can't spot the red wheel in glxgears, here's another screenshot from it.

[Tomas (tomas-redhat-bugs)]

We unfortunately don't have such device in house, Martin will you be able to test once test package is available and I can get the way how to distribute it to you?

Thanks
Tom

[Martin (martin-redhat-bugs)]

Hi Tom, yes, I am able to test, but it may take 7-14 days until I can provide you with the results. Just send it via e-mail. Thanks! :)

[Xavier (xavier-redhat-bugs)]

FWIW, we don't have such hardware upstream either. However, I've just ordered a board with an IGP from the same family, so I'll hopefully be able to reproduce the issue in the coming weeks.

[Jsimmons-t (jsimmons-t)]

Hello.

  The image corruption deals with the hardware cursor. I have seen this issue as well on my VX900 laptop but it doesn't happen all the time. Because of this I haven't been able to track down the problem. If you run into this problem all the time then we might be able to solve it. Also I never seen it in UMS mode like you have which tells me the same cursor bug exist for both the KMS kernel and the xorg UMS code for the cursor. Does this show up only on the LVDS or when you have external monitor plugged in? As for the wrong colors that is a kernel drm bug for the second display. I have seen it recently with my multiscreen testing for KMS.

[magilus (magilus)]

I tried using an external monitor but it does not work in any scenario (black image) - either because of the VGA-port being defective or a bug in the driver.

Fix colors on second crtc

Can you try this patch against the drm-opernchrome tree. This should fix the wrong color issues you see. The cursor is still not fixed. I thing it is a initialization issue.

[magilus (magilus)]

drm-openchrome tree with that patch (via.modeset=0) shows the same behavior.

Can you try with modeset=1. This patch only impacts KMS mode setting

[magilus (magilus)]

with via.modeset=1: colors ok, image still blurry.

[Jsimmons-t (jsimmons-t)]

Can you post Xorg.log and dmesg.

Here is a patch for broke cursor issue. Let me know if you can now use the second cursor.

Test patch to see if LVDS is TTL

I have been thinking about why your LVDS is blurry. It could be a TTL based LVDS. Please try the test patch attached.

[magilus (magilus)]

applied the "Test patch to see if LVDS is TTL", and it works - great.

Not sure what the cursor patch is supposed to do (applied it, though), as far as I know the cursor issue only appeard with via.modeset=0 (I have taken out the swcursor option in xorg.conf)

FYI, James Simmons seems to have found a solution (at least for the issue in the drm kms tree of openchrome). Have a look at the upstream bug.

[Jsimmons-t (jsimmons-t)]

Much better. Could you post the output of dmidecode. I can use that output to handle your LVDS special case.

Hi. I was having this problem every time on Lubuntu Live CD/USB, but it also happens sometimes after installation.

Thanks. I updated the drm-openchrome tree to handle your case automatically.
