Ubuntu 10.04 LTS 64bit on Sandy Bridge

[Goi]

Hi,

Wondering if anyone got this to work?

I have a HP desktop that has a i5-2400 and a Q65 Express chipset with Intel 3000 graphics. I've installed Ubuntu 10.04 LTS 64bit on it, and so far, it's not working very well.

At first, the graphics wasn't working - the max resolution I got was 1024x768, and the same desktop was shown in both my monitors(dual monitor setup). However, I downloaded glasen's intel drivers, and that fixed the problem.

However, my mouse and keyboard are extremely laggy right from the start when I installed the OS off the Live CD. The mouse cursor frame rate is abysmally low, and if I type at a normal speed or faster, it would not register keys regularly.

I've installed the same Ubuntu 10.04 onto another system with an older i5-750 system, and that works flawlessly, so it's probably a Sandy Bridge driver issue. I've read many people having problems with 10.04/Sandy Bridge.

Are there any chipset/USB drivers that I need to install?

Thanks.

Have you tried 12.04? 10.04 will be out of support next year. I dunno about the specifics, but the newer kernel with 12.04 may help.

Yes I've tried 12.04 and it works. However, I need to use 10.04 LTS as I'm building the Android source code and that's the only supported version.

I did some investigation - when plugged into the front USB ports (bus 002), no lag. It's only when I plug them to the rear USB ports (bus 001) do I get the lag.

/proc/interrupts shows the following:

Seems like ehci_hcd:usb1 is causing a lot of interrupts on CPU0, possibly slowing it down? How can this be fixed?

I'm not really sure how to to read that, but my /feeling/ is it isn't an issue. I don't think Ubuntu 10.04 is a hard requirement. It's widely used, so that's what they did their testing on. Any modern distro, or version thereof should work fine. If you REALLY need 10.04, you could run that in a vm inside a more modern distro.
