I'm looking at getting an Intel NUC in combination with a high resolution monitor and want to run Linux (Ubuntu) on it. It's quite difficult to discover what resolutions and refresh rates are supported by the i915 driver for each GPU.
In general my question is: given an Intel CPU/GPU combination and a desired resolution/resfresh rate, what's the best way to discover whether it will work (without trying it out :))?
Thanks for any help! (PS. I tried adding links for the documents mentioned in 3a/b, but they couldn't get past the spam filter.)
Edit: In the meantime, I have discovered some relevant documentation very close by: the Documentation-link on the left! If I choose a platform there (for example, "2013 Intel Core Processor Family") I can then select "HSW - Volume 11a: Display", which contains a lot of information (starting on page 147).
The problem there is that the information is quite cryptic: I would have to know realistic values for primary plane, sprite plane, panel fitting and down scale amount... But maybe the table on page 154 shows a baseline to derive values from?
Interesting question - I don't know the answer, to be honest, but if I were you I'd try the #intel-gfx channel on freenode irc - some of the developers hang out there and they're the mostl likely people to know.
