or Haswell? Both names appear in the log...

Graphics used to work on this device (beta3, and some nightlies until halfway to beta4 at least), but I do not remember whether that was running on framebuffer automatically.

So this may be a regression.

Broadwell is correct. No edid is found, only the resolution in the VBt is found. The driver isn't really able to switch to a non native resolution it seems. So it's supposed to be connected with eDP.

What's the exact PCI id for the graphics de vice?
