Public bug reported:
Please see https://bugs.freedesktop.org/show_bug.cgi?id=27001
I assume that this is now ( as of yesterday ) in the upstream kernel.
However, all kernels so far shipped with lucid have the issue and it
would be good if it could be patched in the Ubuntu Lucid kernel before
release.
The net effect is that anyone who has a monitor requiring dual-link DVI
will have no display on upgrade or install of a version of lucid - and
given the simplicity of the fix it is probably an annoyance that could
be avoided!
