Recently, I have replaced my old motherboard Giga G41M + Pentium 5500 CPU with the new Giga B75M + Celeron G540 CPU.
The old motherboard has an on-board GPU, Intel GMA X4500.
The new motherboard has no on-board GPU, but the new CPU has an on-die GPU, Intel HD Graphics.
I'm running Debian testing, without reinstall after upgraded the hardware. Command
lspci -vk shows the driver
i915 is in use for the video:

Now the problems,
i915works, but it seems a bit of too slow. For example, it can only play the video "Ducks take off 1080p" less than 1 fps.
2nd generation...lspci reported the right generation? In the Wikipedia it shows my Intel HD Graphics is the 6th generation.
i915the right driver for my Intel HD Graphics? It seems the module name for HD Graphics is
intelfrom some Ubuntu sites. If so, I can't find the
inteldriver for Debian. Should I use the ubuntu sources.list? Where to get the
- Or, maybe I can simply let Xorg to rescan the hardware and re-pick the right driver for me?
