Are you running it on a 6593g Laptop?
Can you extract it as a .ROM file ?

i noticed that your bios extracted with GPU Z is 512 byte bigger than mine.

is working on a 5920g, I extracted with gpu-z, if you tell me how to copy vbios.rom you upload it without problem

@Hycks: Install kernel sources & necessary compiler tools.

Then, edit drivers/gpu/drm/nouveau/nouveau_bios.c, and delete the line "if (conf & 0x2)".

Then, recompile the nouveau module.

This should allow nouveau to pick up the EDID. (This is not the "right" fix; ACPI EDID should be used depending on the relevant MXM structure field. I've suggested that to nouveau's developers, but they won't fix it because "this (i.e. the current behavior) is what the nvidia proprietary driver does" and "we do not support or condone aftermarket MXM upgrades".)

.NetRoller 3D, i've downloaded the 62.94.7A.01.06 bios + a backup from this one and NVFlash 5.95.0.1.

Flashing a GPU is a procedure that i've never done before and it seems my brother isnt really into it either (even though he's done it, he doesnt wanna mess up) ... We were wondering if you(or anyone) could point us to any page/guide out there explaining what are the parameters needed to flash this thing. >_>

Many thanks in advance...

@NetRolller : Thank you for your answer. But I must admit that I have never recompiled a kernel source or module... I know how to compile programs and even how to write them, but using ubuntu and linux is very new for me...

So, could you indicate me the main steps of how to proceed in this driver mod? I tried to read tutorials on the web, but things are not so clear. Here is the ubuntu version I use : 3.0.0-17-generic... Sorry for asking you things like this, but this would really help me....

By the way, is it just the very line "if (conf & 0x2)" I have to comment? So I should letthe following line "entry->lvdsconf.use_acpi_for_edid = true;" uncommented, right?

Many, many thanks for the help, and sorry again for my "noobiness", but I am really want to learn and help others for future cases... To think perhaps I'm only one step away for using again my 9920g makes me eager to make this attempt soon! héhé

@Hycks: Only the "if" line needs to be commented out.

Unfortunately, you are using Ubuntu, a distribution that actively discourages using self-compiled kernels or modules. The kernel sources are packaged only to conform the GPL; Ubuntu actually takes steps to prevent you from compiling those sources. The usual response to kernel compile questions on the official Ubuntu forums is "Don't compile anything, use only prepackaged binaries".

With that said, try asking someone with more experience dealing with Ubuntu - I've abandoned it in favor of OpenSUSE precisely due to the aforementioned "Use precompiled binaries" attitude, which is IMO runs counter to the spirit of F/LOSS.

A tutorial that may help can be found @ How to compile a new Ubuntu 11.10 (Oneiric) kernel - this actually rebuilds the whole kernel, as apparently Ubuntu doesn't allow compiling modules for kernels that you didn't compile yourself.

NetRoller, just did the flash to the 62.94.7A.01.06 bios. Didnt resolve the issues though... Any other ideas? I'm guessing this card just wasnt made for this Acer. (still, doesnt make sense) Lucky me.

PS: i have the 1.21 Acer bios. Suppose its the newest one around?

Check if there is newer SBIOS available, and update as needed.

Been searching for a while and cant seem to find anything newer than this one (dated 03-03-2011). On the official acer website they only have 1.10, 1.13 and 1.20 aswell.
I'm presuming that doing a SBIOS rollback wouldnt solve anything either. *sigh*
