Comment 22 for bug 1064924

Yes this bug remains an issue for me, the problem really is there is no solution that works for everyone.

Just to recap the problem with these machines is that they have an external HDMI encoder which is hooked up to the LVDS output of the GPU. Linux itself doesn't support configuring that encoder, so unless you're lucky enough that the bios/default hardware setup of the encoder matches the equipment hooked up to it HDMI output doesn't work. Which leaves two options:

0) Add a no-lvds quirk, which disables the LVDS output alltogether
1) Not adding a quirk, which does mean HDMI out works if the stars align just right but causes issues for those not using HDMI
     or those that are less lucky.

Linux upstream picked solution 1, as option 0 causes regression for those folks which have correctly aligned stars. Which means i'll keep seeing the issue as i'm not using the HDMI out.

The only real solution for this would be for someone to add support for the external encoder to the kernel, which is a non-trivial amount of work and is relatively unlikely to happen as it's a quite old chipset by now.
