Hi everyone.
Currently I'm installing Linux Mint 17.1 Rebecca - Cinnamon on Microsoft Surface3.
(Not Surface Pro 3, but Surface 3 with Atom x7-Z8700 cherry trail and Intel HD Graphics)
I could install mint linux successfully. However, 3D graphics wasn't enabled.
So I tried other ways - change linux kernel to 4.1.0-rc4 drm-intel-next from http://cgit.freedesktop.org/drm-intel and update mesa version.
But it didn't show successful result. According to dmesg it seems i915 DRM driver isn't initialized correctly
So I'm wondering that the latest i915 DRM driver doesn't support Surface3 yet? or is there other solutions?
Below log is kernel dmesg when drm failed. Thanks in advance :)
