Xorg log - without KMS

I have a benq monitor and a (RV380 3E50) PCIE card which if I understood correctly should be supported by the kernel 2.6.31-rc4 so I decided to try it.

As soon as the module auto-loaded the monitor was driven out of range.

I attached the Xorg log so you can take a look at the reported EDID info (I'm not sure about it but I think it should be ok since it works fine with a lot of cards without any "tuning" in X)

Let me know if you need anymore information and I'll see what I can do to get it.

Can you attach your dmesg and xorg log when kms is active?
Comment 2 Radu Benea 2009-07-28 14:12:10 UTC
I'll try tomorrow, should be able to ssh in from another machine

dmesg from KMS kernel

the log sends out an error about not finding i2c data, that's because there's nothing connected to DVI output, my monitor is connected to VGA connector

Xorg log - with KMS

I don't know if this is very helpful the log suggests that the driver went around KMS instead of using it and initialized succesfully (not for long though), maybe I should have recompiled some stuff?
if yes let me know what to recompile to work with KMS

Do you have fbcon loaded?  You won't get a frame buffer console without it.

as soon as I loaded fbcon it worked, thanks
