[Bug 564559] Re: URGENT for upcoming release: Resolutions requiring dual link DVI on radeon result in no display

[thehighhat]

OK.  I was unaware that "nomodeset" was deprecated.  Fair enough.

*.modeset=0 does not work for either the nvidia or radeon hardware.  I
actually tried this first before settling on nomodeset.

I do not see how this bug is marked fixed.   It seems that requiring a
user to add special boot options (when the display does not even work)
and depending upon PPA is not optimal.

Fixed to me would mean that the detection of problematic hardware
happens automatically and the appropriate boot option are added
transparently to the user.  Or, that the 2.6.34 kernel updates get
backported into the LTS kernel (this is approach redhat takes).

There are other bugs referencing this problem that are marked as
duplicate.  The general description here (dual-link DVI modes are
broken) is appropriate.  And this bug is not limited to radeon, but also
nvidia (I have not tested intel, matrox, etc.).    Also, the title
suggests it is a pre-release issue.  Lucid released a month ago.  The
bug persists.

Don't get me wrong.  I like the PPA tools.  And I am glad that a
knowledgeable user can add boot options.  I just think that these things
are not fixes per se.  They are tips to help a user deal with broken
product.
