I was able to get my new h67-based sandy bridge system running on fedora 14 linux with graphics without much trouble.
Little more than:
yum --enablerepo=rawhide install kernel
yum --enablerepo=rawhide update libdrm
yum update mesa-dri-drivers mesa-libGL
yum install xorg-x11-server-devel
download xf86-video-intel-2.14:
configure
make
make install
cp the intel_drv.so from /usr/local/lib/xorg/modules/drivers to /usr/lib64/xorg/modules/drivers
change /etc/X11/xorg.conf to use the intel driver
That's not so hard is it? Don't even need to do a fresh OS install.

Intel Sandy Bridge Linux Graphics? It's A Challenge

I can not test sandy bridge, but most likely a daily build of u 11.04 might be able to use the internal gfx card already. When they would include a recent libva then xbmc or vlc (or a special mplayer which is not the default one) could use accelleration too. You definitely can forget distributions released 2010 for sb.

Nvidia as An Interim Solution?

I don't think that it will be a good gameing cpu. It is restricted to opengl 2.1 most likely on Linux. Usually win drivers are much faster for games (dx10 support would be opengl 3.x hardware). Libva support seems more interesting for Linux users, but those cpus are really powerfull too now...

I wonder if in the future it will be possible to buy a laptop with only a sandy bridge cpu (with integrated HD3000) and none discrete GPU and play to open source and Wine games.
Is the 3D acceleration already in the kernel driver?
Thank you,
Xwang

Yes, the code was not changed however since last year. When will you update your libva?

This week at the Consumer Electronics Show in Las Vegas (I'll be there looking out for Linux), Intel will officially launch their next-generation Sandy Bridge micro-architecture and CPUs. The NDA though expired at midnight on these first CPUs so there is now a stream of reviews coming out. Is there any Linux graphics test results for the Core i5 2500K and Core i7 2600K? Unfortunately, there is not...

Some tests:

that implies program error somewhere not hardware errata, someone should perhaps ask for clarity and post a test case to prove it on [email protected] as we are just assuming right now it seems!
The limitation is entirely in hardware, particularly in what?s supported by the 5-series PCH (remember that display output is routed from the processor?s GPU to the video outputs via the PCH). One side effect of trying to maintain Intel?s aggressive tick-tock release cadence is there?s a lot of design reuse. While Sandy Bridge was a significant architectural redesign, the risk was mitigated by reusing much of the 5-series PCH design. As a result, the hardware limitation that prevented a 23.976Hz refresh rate made its way into the 6-series PCH before Intel discovered the root cause.
Intel had enough time to go in and fix the problem in the 6-series chipsets, however doing so would put the chipset schedule at risk given that fixing the problem requires a non-trivial amount of work to correct. Not wanting to introduce more risk into an already risky project (brand new out of order architecture, first on-die GPU, new GPU architecture, first integrated PLL), Intel chose to not address it this round, which is why we still have the problem today.
