LaCie 321 DFP: mode misdetected - EDID misinterpreted?

[Mourad De Clerck]

Hi,

I've got 2 LaCie 321 DFPs, but can't seem to drive them at the native
resolution (1600x1200) with the open "nv" driver. The maximum resolution
I'm able to use is 1280x1024.

I don't have any problems driving both at the native resolution with the
closed "nvidia" driver. In addition, I seem to remember having the same
problem with the DVI output of an ATI Radeon 9200 and the corresponding
open "radeon" driver - though I can't verify and confirm this at the moment.

Attached are the logfiles and conffiles of the "nv" and "nvidia" drivers
resp., to highlight the difference.


In the xorg-nv.log you'll notice:

(II) NV(0): Supported VESA Video Modes:
...<snipped lower resolutions>
(II) NV(0): 1280x1024 at 75Hz
(II) NV(0): 1152x870 at 75Hz
(II) NV(0): Manufacturer's mask: 0
(II) NV(0): Supported Future Video Modes:
...<snipped>
(II) NV(0): #7: hsize: 1600  vsize 1200  refresh: 60  vid: 16553
...<snipped>
(--) NV(0): CRTC 0 is currently programmed for DFP
(II) NV(0): Using DFP on CRTC 0
(--) NV(0): Panel size is 1280 x 1024
...<snipped>
(II) NV(0): Not using driver mode "1600x1200" (exceeds panel dimensions)
(WW) NV(0): Shrinking virtual size estimate from 1600x1200 to 1280x1024


I don't have the logfiles of the Radeon 9200 with the same screen(s),
but the symptom was the same: instead of displaying at 1600x1200, the
maximum resolution was 1280x1024.

Does anyone have any idea how to solve this issue?

Thank you,
