HDMI shows only black/white static noise

[Tim Kornhammar]

More on the issue: For 1 second it shows the desktop, then goes into a black/white static noise, no errors or debug info can tell what is wrong. This is repeated every time I turn on the HDMI connection.

(hopefully this is the correct arena for this bug)

The problem has existed since I bought the computer but when I used Ubuntu 11.04 and 11.10 I could work around the display issues by setting the screen size to 4:3 and 1280x1024 px on my 40" Sony Bravia 1080p screen.

Now in 12.04 that does not work any more, the only thing that does work is by setting some options in xorg.conf and relying on the VGA connector.

$ lsb_release -rd
Description: Ubuntu 12.04 LTS
Release: 12.04

$ aptitude show libdrm-intel1
Version: 2.4.32-1ubuntu1

For the moment Iäm trying if linux-image-3.4.0-1-generic with edid_firmware loading solves the issue, it does not even though I have tried a lot of different approaches. Loading the edid from windows does not work either since it uses 1 edid cea extension.

In the logs I enabled as much as I could through xdiagnose (it set drm debug to 0x14, I guess that is ok over 0x06 which was recommended on intels debugging site). Even though I have looked in the logs I cannot figure out what is causing the noise.

If you would like me to create the logs with the stock kernel I can, but I don't think it will help much.

I found an earlier bug which I reported when it "worked", no static noise. Adds the link here because it shows some information on packages and logs when it did not behave in this manner.

[Lucid] External screen is reported to be 70" instead of actual size 40"

Hmm, can you please reproduce on an updated stack?
