MacbookAir2,1 and 3007WFP

cputoaster · 04-08-09, 08:46 AM

Hi,

I am trying to get my new macbook air with 9400M gfx to work with the 2560x1600 dell 3007WFP display. It work perfectly in OSX, but I can only get 1280x800 in Ubuntu 8.10. Any ideas of a magical setting or similar? I played around a bit with manually entering the modeline etc, but as you can see, it fails with "Unable to construct hardware-specific mode timings". Naturally, I can try updating to the most recent nvidia driver, but I could not find anything in the changelogs related to this type of issue.

Cheers,
cputoaster

Code:

(--) NVIDIA(0): DELL 3007WFP (DFP-2): Internal DisplayPort

The 3007WFP doesn't have a DisplayPort input, does it? Are you using an active mini-DP to DVI adapter? If so, this seems to be the problem:

Code:

(II) NVIDIA(1):   Validating Mode "2560x1600":
(II) NVIDIA(1):     2560 x 1600 @ 60 Hz
(II) NVIDIA(1):     Mode Source: EDID

[...]

(WW) NVIDIA(1):     Mode is rejected: Unable to construct hardware-specific
(WW) NVIDIA(1):     mode timings.

Please clarify how you're connecting the monitor to the laptop and I'll try to reproduce the problem. Also, please try a newer driver. 177.82's DisplayPort support is a bit half-baked.

Thank you for your quick response. I am using the official Apple dual-link mini-DP to DVI adapter. http://store.apple.com/us/product/MB571, which works fine with OSX. I*will try the newer driver as soon as possible.

Cheers,
Andres

Hi again,

I just updated the driver, and everything seems to work fine now. Sorry for the inconvenience, you might want to put a note into the changelogs...

Thx a lot,
Andres

Thanks. I'm glad to hear it works!
