[Bug 657509] Re: DRM: Invalid EDID Checksum - External Monitor DVI -D not recognized by Kernel / Intel Graphisc Driver

[Corné Verbruggen]

It seems that the VGA connections does not work properly either. Maybe
this is a separate problem, maybe not? When trying to attach a 1600x1200
Samsung  SyncMaster 204Ts i get:

Oct 25 09:15:48 legato kernel: [  179.148134] i915 0000:00:02.0: VGA-1:
EDID block 0 invalid.

I can only choose from some low resolutions, not the 1600x1200.

When connecting this panel to the DisplayPort (trough the DP to dual-
link DVI adapter), i get again:

Oct 25 09:28:11 legato kernel: [  920.293647] i915 0000:00:02.0:
DisplayPort-2: EDID block 2 invalid.

So not exactly the same message about an invalid checksum that I get
when I connect the 2560x1600 panel, but I assume related to the same
bug.
