Re: nv driver with HP 30" not getting 2560x1600 - only 1280x800
That's why I made that option disabled by default. At boot, your GPU is not running at a high enough clock frequency to be able to drive that mode. On some GPUs, the VBIOS aggressively underclocks the card to conserve power and reduce heat, relying on the nvidia driver to raise the clocks later as needed. Unfortunately, clock programming is very complex and slightly dangerous, so the nv driver doesn't even try. I'm afraid that if you want to use that mode, you'll need to use the full nvidia driver.
