Adam Hill (sidepipe) wrote : URGENT for upcomming release: Resolutions requiring dual link DVI on radeon result in no display

Please see

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!
