Default Re: Issues with Dual Screen on Thinkpad W700ds & Linux

Thank you, desperadus, that's very helpful. It appears that the driver is unable to read the EDID if your "sidekick" monitor, so it's using the refresh ranges in your "Monitor1" section. You'll need to start X with "startx -- -logverbose 6" as described in the sticky post to tell for sure, but I would suspect that either there is no built-in 1280x768 mode, or it's getting rejected because it has a hsync frequency of around 47 kHz and the valid range you specified is 61 - 73.2. Also, the +1920 is not necessary in the MetaModes line unless you're using TwinView. You should be able to just remove the "metamodes" option from the "Screen1" section, because the Modes line in the Display subsection should take care of selecting the modes for that screen.
