Bug Description

== SRU Justification ==

Impact: On some machines with an Ibex Peak PCH, SSC will be enabled on the clock source used for analog outputs. This results in poor quality output (described as "wavy") on the external display.

Fix: A series of upstream backports to the i915 driver. With these backports, i915 will check for the existence of a CK505 clock source, and if present this is used as the clock source for analog outputs so that SSC can remain enabled. Otherwise SSC is disabled. The PCH refclk update code is also split out so that it can be called from additional locations where the refclks should be updated.

Test Case: Running with backports on an affected system will fix quality issues on VGA outputs. Verified for oneiric on LP #614238.

---

A similar problem with Lucid was reported mainly by users of ATi Radeon graphics hardware. I also experienced the "wavy" output in Lucid, although the graphics h/w is the integrated intel that comes with the Core i3 processors.

It is easy to reproduce. Just plug in an external monitor or projector. The output is not stable/solid and has waves that make it unusable.

I tried the Maverick Alpha3 to see if it had been addressed in the 2.6.35 kernel but the problem is still apparent.

The LCD display of the Laptop is rock solid and sharp. This only affects the external VGA from what I can tell. I do not have any hdmi devices to test with so cannot confirm if the symptoms are just VGA or any external monitor connection.

Similar bug reports from Lucid include: 537640, 541501, 557814, 562138 although these all seem to relate to the ATI chipsets, the description of the problem sounds the same.

I am happy to try upstream kernels and build/patch/compile if necessary.

Here is a similar sounding bug# 600407 although this one refers to a desktop by the sound of it and the reporter indicates it might be a regression after 2.6.31-16.

Alan Lord (theopensourcerer) wrote :

I found a 2.6.31-13 Karmic kernel image in http://kernel.ubuntu.com/~kernel-ppa/mainline/ and tried that.

Unfortunately the wavyness was still present.

The whole desktop also locked-up shortly after logging in so it wasn't much of a test I'm afraid. Booted into the Maveric kernel and disabled Compiz. Then rebooted back into the 2.6.31 kernel. The desktop no longer locks up but the external display still has the wavyness.

One other point to note is that neither kernel is correctly detecting the external monitor via EDID. The maximum resolution I can set for the external monitor is 1360x768. My monitor is a native 2048x1152 Samsung 2343BW. Although the wavyness also occurs on an external 1024x768 projector too.

Any other suggestions to help track this down?

Alan Lord (theopensourcerer) wrote :

Further update. I went out and bought an HDMI cable as my new TV has HDMI.

I've just booted my laptop on the current Lucid kernel and plugged it into my TV using HDMI. The supported screen resolutions are detected and the display on the TV is rock solid.

So it looks like it's a VGA output issue.

Hope this helps.

Hi Alan,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Hi, I have the same problem with a Dell Vostro 3300, i3 processor, Intel

I have this issue since June that I bought my Dell. The problem appears with my Acer
projector and also with a new Packard Bell flat screen, only that with this last one
sometimes the image flicker and sometimes doesn't appear, just I get a blank screen.

I was looking for on internet and there are a lot of reports of this problem, not
only with Dell also with other brands. Tthere is a guy that says that he have a solution but to apply it he
suggest to download and install a special 2.6 kernel version , I don't like a
lot the idea, this is the link:

http://beyondteck.blogspot.com/2010/05/flickering-monitor-in-ubuntu-1004-for.html

Could be possible that it's a solution?

I'm working with the latest kernel that I can download from the update manager: :

Release 10.10 (maverick)
Kernel Linux 2.6.35-22-generic
GNOME 2.32.0

If you need more information, just let me know. I'm relatively newby in linux
but I have a lot of years in IT.

#12 The link you refer to is for issues with ATI graphics cards.

I am not sure if that is the same or a different bug to this one which is for intel Core i3 & what looks like Core i5 chips.

If you have a DVI or HDMI output these seem to work fine. The problem appears only on the VGA output.

I have the same problem on a Thinkpad R60 with ATI card, but in that case the "nomodeset" or "radeon.modeset=0" kernel parameter helps!

If I try to set "nomodeset" or "i915.modeset=0" for Intel i5, than X server crashes immediately!

I can see installable packages in the standard repository related to intel core i5 microcode. Do you think that installing those microcode packages could help? I dont think so but who knows?

Anyway, the vga output problem is related to this kernel bug:

Setting the screen refresh rate from 60 to 75Hz has brought a little improvement, nevertheless it's unusable.

Have this issue with Ubuntu 11.04. Toshiba Satellite L645 laptop and Intel Integrated Graphics display.

I can get a temporary workaround by doing the following:

1) Open the laptop lid
2) Fn + F5 to scroll vid-modes, switches to "duplicate display", output fine on both heads but not desired res. on external.
3) Monitors > uncheck duplicate display, move external to primary position > Apply

5) Turn off laptop display > Apply. Everything OK.

if 3, 4 and 5 are done in one step, it seems to hang X in a black screen state w/ only mouse cursor visible.

When I reboot or detach/reattach the external monitor, I get a purple wobble or blank screen on the external monitor and have to repeat steps 1 through 5. Sometimes I have to kill X to get back up. Is this an issue only w/ 64-bit Ubuntu? I'd happily switch to the 32-bit version to avoid it.

Thank you for the info T Martin. I have tried Fedora and had the same issue so I did not try any other Distros out. I will give xubuntu a try tonight and see if the problem persists.

Hi,

I remember you that I have a Vostro 3300, i3 with a Intel card. At the moment, the VGA screen was waving.
Yesterday I updated my Ubuntu to the version 11.04 (natty), kernel version 2.6.38-8-generic, and now the external screen doesn't work at all.

If I plug it at the begging, the behaviour is similar as it was, waving and sometimes a line with strange colours. But after I login in, I can't see anything, just the mouse cursor, only part of it, a frozen screen or the system tray (but I can move windows to my external screen).

The flickery/wavy screen is allways there. May be is it a new bug?

Kind regards,
Fernando Hidalgo

Jesse,

I was just checking up on the status of these patches. Looks like the first one made it to Linus's tree, but Keith backed out the second because it causes a regression:

https://bugs.freedesktop.org/show_bug.cgi?id=40031

Any idea on what needs to be done to address this?

Thanks,
Seth

Does this bug will be fixed in kernel 3.1?

I recall that it was first reported over a year ago, only as the old report was closed and opened new, it always looks better error for two months than in over a year.

Is the regression more important than this bug ? I mean, with the patch my computer is working perfectly.

Chris, whether this patch will be submitted in merge window kernel 3.2 ?

Sorry, I forgot to tell you.

This issue was discussed in intel-gfx recently. Keith wrote a series of 9 patches on the code that is used by this bug.

I believe the patches landed here:
http://cgit.freedesktop.org/~jbarnes/linux?h=fix-pch-refclk

And the one that solves our problem is:
http://cgit.freedesktop.org/~jbarnes/linux/commit/?h=fix-pch-refclk&id=99eb6a01e5ac6cf28aadc64e6ff346939874dfd2

The root-cause is that on our machines we need to use DREF_NONSPREAD_CK505_ENABLE instead of DREF_NONSPREAD_SOURCE_ENABLE when setting the PCH_DREF_CONTROL register.

I don't think this will come for 3.1, but at least now distros can try to backport something :)

More information to help:

If we're going to do a "minimal" backport we need:

- this patch: http://lists.freedesktop.org/archives/intel-gfx/2011-September/012172.html
- follow the comments here: http://lists.freedesktop.org/archives/intel-gfx/2011-September/012198.html

The first link on this comment is the patch that "caused" Keith's rewrite. If you want to fully understand the problem, I recommend you to read all messages on that thread and also all replies to Keith's patch series (sent a few days after the discussion).

Thank you very much for answer :)
I'm currently using the patch from comment #12 this discussion and it works well, but every now and then I have to recompile kernel on ArchLinux (7 times, v3.0.7 :), so I want to know if the amendment shall enter into a stable kernel release, in version 3.1 is probably not possible, but maybe in version 3.2?
The bug has been over a year, whether he is a chance that once it goes into the stable kernel relase, it was not necessary to create backports?

Hi,

I am trying to get use the 3.0 patch. I have downloaded the patch above to my home directory, downloaded the 3.0.0 source using apt-get. i've also have libncurses5-dev and gcc installed and updated and upgraded everything with apt-get.

can anybody tell me what i'm doing wrong? I'm sure after i've patched it properly the compiling/installing of the new kernel will be no problem.

Cheers,

Louis

When you type :
"sudo cat /home/louis/patch.diff | patch -p1"

You run cat as root and patch as louis. Then the error message should become clear to you. Anyway, you should do everything in your home and avoid touching the files in /usr/src.

Please avoid using this bug report ticket to ask how to apply a patch, you should use a forum for this kind of question.

Can you share patch for kernel 3.1? I tried the above but do not match.

Is there a chance that the bug is fixed in kernel 3.2?

Yes, a pull was already requested.

See:
http://lists.freedesktop.org/archives/intel-gfx/2011-October/012856.html
http://cgit.freedesktop.org/~keithp/linux/log/?h=drm-intel-next

Please test drm-intel-next. I hope Linus will pull this soon.

Created attachment 52870
drm-intel-next patch in kernel 3.1 (fix waves)

Thank you Paulo

Currently I test drm-intel-next and it works perfectly, no waves.
Previously, when switching screens sometimes appear gray screen and had to switch again, now drm-intel-next yet this did not happen.

I created a patch for kernel 3.1 on drm-intel-next, the file in the attachment.

I hope that this can be included in kernel 3.2 :)

Fixed in Linus' 3.2 tree.

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=commit;h=99eb6a01e5ac6cf28aadc64e6ff346939874dfd2

Fixes my machine. Closing bug. Reopen if that doesn't fix your machine.

how do I apply this patch. I'm not really good at these things ? I've had this error for ever and I can't get it fixed... can it get merged into update or something ? Thanks

I have come across this, howev.er:

and post it here in case it is relevant.

Thanks, Martin

Output on an external monitor is wavy with either Seth's image or 3.2.0-5 from precise.

The hardware is different -- i7-2720M, Sandy Bridge. Should I file a new bug?

Sergey: I'm fairly certain that yours is a different issue. According to
the comments in the code at least, the SSC shouldn't impact the analog
outputs for the chipsets used with Sandy Bridge or later. So please go
ahead and file a new bug by running 'ubuntu-bug linux' in a terminal.

It means I've started the process of getting these into a future oneiric
update. We're still several weeks from having a release containing the
fix.

This bug is awaiting verification that the kernel for Oneiric in -proposed solves the problem (3.0.0-15.24). Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-oneiric' to 'verification-done-oneiric'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

This means no blury display on a IBM Thinkpad i410s with Intel iCore5 and intel graphics adapter.
Somehow I don't have a 3.0.0.15.17 but updated the kernel from the proposed sources.

Hope that helps.

Problem solved in Dell inspiron n4030.

Hi,

the problem came back with linux kernel 3.5.3 (using Archlinux with latest intel 2.20.6 drivers).

Whoops please ignore my last comment, wrong kernel version.
