Bug Description

During boot my screen goes blank. Instead of a normal plymouth screen I see something like this:

[drm:edid_is_valid] *ERROR* Raw EDID
[drm:edid_is_valid] *ERROR* Raw EDID
[drm:edid_is_valid] *ERROR* Raw EDID

this might be a problem with intel's i915 chipset. This bug comes new with 10.04 - it never appeared with ubuntu 9.10.

Not sure what the bug is here, reassigning to Yakui. Invalid EDIDs can be due to bad timing on the kernel side, flakey hardware or cables, or a real bad EDID in the monitor.

It's notebook Sony Vaio VGN-C2S_L, so I suppose it's bad EDID, and not cables ;)

Will you please add the boot option of "drm.debug=0x04" and attach the output of dmesg?

Thanks.

Now it only reports:

[ 23.903220] [drm] Initialized drm 1.1.0 20060810
[ 23.908682] i915: no symbol version for module_layout
[ 23.932410] i915: no symbol version for module_layout

(no symbol version probably due to my way of compilation).

Does this ignoring LVDS can make some problems or is it safe?

Since that change my X.org eats many CPU, and everything is working extremely slow.

At least I'm finally able to run Enemy-territory game, but it works so slow, that I have to try to select proper option to be able to exit from the game.
Before that patch I wasn't able to even run it (signal 11).

Seems there's something wrong with hardware acceleration after that patch.

Is there something else I can provide you to resolve these issues?

It seems that the slow issue is not related with this bug. And from the log it seems that the xorg will query the status of every possible outputs periodically.

Can you provide the info of "cat /proc/interrupts"?

Thanks.

Now the corresponding patch is already shipped. And after the patch is applied, it can avoid the warning message of "drm:edid_is_valid" perodically.

drm/i915: Ignore LVDS EDID when it is unavailabe or invalid

So this bug will be marked as resolved.

Thanks.

Hi Jan,

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.

Thanks in advance.

Hi Jeremy, are you still with me?

Maybe this is something: "i915 0000:00:02.0: LVDS-1: EDID" - I don't know, but to me it looks like that the kernel expects to handle an i915-Chipset (with a GMA 900 graphics core). In fact I have a Mobile Intel® 945GMS Express Chipset (GMA 950).

Jan,
I am. It appears that this is in the same direction as some of the other reports I have seen. I've set the bug to triaged for a kernel team member to take a look at, but sue to UDS this coming week, it may be a bit.

Thanks!

Hi Jeremy,

I asked Yakui Zhao from intel to have a look on this thread. He said, from the log it seems that his patch is not shipped in the kernel I used. He will send it to the stable kernel.

thanks to both of you.

I have similar issue early I sent comments to bug 536827 but now it has Fix Released status.

So here is my experience with upstream kernel.

Zhao's patch already is in upstream from 2.6.34-rc5-lucid ( http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc5-lucid/CHANGES )

With this kernel I see no "*ERROR* Raw EDID" when boot or shotdown.
Still there are several [drm:drm_edid_is_valid] messages in dmesg but only ones:
i915 0000:00:02.0: LVDS-1: EDID invalid

I suppose it is what mention patch must do.

Jan, try latest for now kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.34-rc7-lucid/

The main thing that I'm wondering (I also have this issue), is why is EDID information even needed by the kernel? Especially in Lucid Server? No gui installed, so I don't even see why it should care, as it not running an X server. Which begs me to ask, why is this not in Xorg, instead of kernel?

I have an Jujitsu Siemens external monitor connected to my Samsung laptop. Bevore I upgraded Ubuntu, the monitor worked fine. Now I'm stuck to my laptop monitor and can't use the external monitor. Got the same error:

[drm:drm_edid_block_valid] *ERROR* EDID checksum is invalid, remainder is 254
i915 0000:00:02.0: HDMI-A-1: EDID block 0 invalid.

This is a pretty annoying bug...

Bryce Harrington (bryce) wrote on 2013-01-18:

When the EDID provided by hardware is invalid or unavailable, there really is little the kernel can do to correct it. In some cases where there is a simple monitor-specific flaw, that can be quirked on a case-by-case basis, however the situation described here is outside that scope, since the EDID is just plain blank.

Disabling use of KMS modesetting (as described in the above comments, and as provided by the upstream bug report) works around the problem but doesn't really "fix" it. A proper fix would be to provide a tool for installing a corrected EDID into the kernel's /lib/firmware/edid. The kernel already supports this, but the tool needs to be provided on the userspace side, e.g. xdiagnose.
