Ubuntu – Does 11.04 support Sandy Bridge

This is Michael Larabel of Phoronix. Sandy Bridge CPU and Cougar Point chipset support under Linux is quite good, sans the graphics bugs and small other hiccups (as pointed out in my articles and already in this thread, don't expect your motherboard to necessarily have LM_Sensors support, there may be some SnR problems, USB3 is generally fine but under some scenarios can be iffy, etc).

In terms of the graphics problems I have noted that some people say is due to a system mis-configuration on my part, that is not the case. Intel's Jesse Barnes is able to reproduce the most severe issue I reported of stability problems / tiling corruption when the system endures enough load. This doesn't seem to happen to everyone or they don't realize it as the system must be under lots of load, but it's happening with at least select ASUS motherboards. I'm waiting on a new board from Intel to see how that goes and how the Linux graphics performance is once everything is working.

I remember logging in and logging out after plugging in the HDMI device and changing the sound settings to HDMI Output seemed to help in my case.

Additionally, running 'alsamixer' in terminal seemed to have made a difference before.
