Comment 54 for bug 127008

Soren,

Ah, well an edidfail could explain it. This doesn't leave us too many options, but possibly the best of the worst is to simply skip xprobe.sh entirely for Intel laptops. I suspect this may result in various other issues, but all much less severe than a hang during installation.

Here is a debdiff and .deb for this. Can you test this to verify it fixes the hang issue, using the approach from comment 30?

As to the edidfail issue, bug 94994 already describes that. My suspicion is that there are multiple versions of EDID, and ddcprobe only supports one version. However, that's something that I'm going to have to leave til later to sort out.
