Intel SNA vs. Modesetting GLAMOR - DDX Benchmarks

[geearf]

xorg.0.log most likely.

What about Ivy Bridge?
Anyone has tried modesetting? Is it even available?

Your distribution has to package and ship it. ON Debian, for example, it is bundled in the xserver-xorg-core package.

To verify, your Xorg log should look like:

IIRC, the biggest benefit with modesetting driver is the following:
