--- Comment #49 from Paul Menzel paulepanter@users.sourceforge.net --- With the debug patch applied to your 3.14-wip branch (based on 3.13-rc4), the following is printed by the Linux kernel.
[ 12.005985] [drm:radeon_fixup_lvds_native_mode], Native mode: 1920x1080-138780
The clock looks strange to me, as I would have expected the refresh rate. But I guess I just do not know what it is supposed to do.
(I had to do eight xrandr off/auto cycles to get the display to work.)
