I had an issue with my hardware setup (ATI Radeon HD4770 + Dell
3007WFP-HC) regarding KMS.
This issue got solved by Alex Deucher in fdo bug 27001:
It has been verified to work and has been committed to upstream:
The problem was that during an Evergreen code merge in the 2.6.33 kernel
(from which you pull the DRM/KMS stuff) support for dual-link DVI
monitors got completely broken on DCE3.2/4.0.
So I have backported the commit to the Lucid kernel 2.6.32-21 and
verified that it works (although DCE4.0 support is missing there).
There is also an appropriate launchpad bug containing my patch:
Please have a look and integrate that patch into the Lucid code base.
