Can you post your xorg log and dmesg output? There are several possibilities: 1. Your panel does not provide an EDID. The driver is still able to determine the native mode timings from tables in the vbios. 2. Your EDID has a bad checksum/etc. and the kernel drm EDID validator rejects it: https://bugs.freedesktop.org/show_bug.cgi?id=31943 You can try the patch on that bug and see if it helps. > > The driver is Radeon-1.3.0 build from git master 80ba041a . > Here some more details: > https://bugzilla.novell.com/show_bug.cgi?id=615740#c21 That bug just looks like a random collection of things vaguely to EDIDs.
