Just upgraded from LM13 to LM14 (64 bit) and now I can't get my dual monitors working right again. Here's the setup:
Release 14 (nadia) 64-bit,Kernel Linux 3.5.0-17-generic
Intel® Core™ i7-3770K CPU @ 3.50GHz × 8
GeForce GTX 550 Ti/PCIe/SSE2
Currently running nvidia driver 304 but I've tried several others with the same results.
O have one monitor @ 1920 x 1080, and one @ 1680 x 1050. Both are connected via HDMI. All I can get is mirrored displays at 1024 x 786 though. the nVidia settings daemon lists lower resolutions, but the highest available is 1024 and that's what selecting AUTO chooses. I would like to get each monitor set to it's native resolution and have the right one be an extension of the primary display.

It was a pain to set up in LM13 as well, but this time the process is different. Before, I had to use the onboard video and install the driver then reboot, change the BIOS to use the video card and activate the driver. Now the video card works right off the bat, but I can't get anything other than mirrored displays. Any ideas?
