Sorry but is the same effect. I attach the Xorg log. I manage to make radeonhd (atombios based) driver to "work" on debian sid/experimental with 2 options. Option "UseAtomBIOS" "yes" Option "NoRandr" "yes"
For more info please take a look at https://bugs.freedesktop.org/show_bug.cgi?id=16892 Thanks for you comment. ** Attachment added: "Xorg log ia4" http://launchpadlibrarian.net/16851200/Xorg.0.log -- [RV635] Gray screen https://bugs.launchpad.net/bugs/252927 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
