HOWTO: Jaunty Intel Graphics Performance Guide

[Cimi86]

who could port this packages to the lpia arch?

[jcapitan]

Um, I'm taking a step back... This is a wonderful fix. Thank you for making it available! But this for a relatively standard video card, not a "vostok-omsk 3". Can/Should a "regular" user who is trying U-9.04 for the 1st time be expected to do this? Just curious.....

Anyone with i845 had success with these workarounds? I mean, success in making Compiz to work? 'Cause I had everything running well here when testing a Jaunty LiveUSB, except by Compiz.

Can you tell me if the Intel integtrated graphics controller 915GM/GMS/910GML is affected?
I ran the live-CD and display was kind of a wreck, though it didn't crash. I have not upgraded. Intrepid is working so well.

edit: on 06-01-09 I did a fresh install of Jaunty--it's flawless out of the box.

The 2.6.30-rc2 kernel gives approximately 4-5fps extra in ppracer for my 855GM chipset (the MTRR fix is necessary for maximum performance). I assume this is because there have been some bugfixes/optimizations in the DRM/i915 kernel modules.

Other chipsets may not see the same performance gains, though it's worthwhile at least to check the newer kernel.

This is correct for 2.6.30rc2 but on rc3 I experienced a regression with my card. Anyway I'm stay fine with 2.6.29-11 with videoram option (I forgot to mention that my box is on EXT4, but maybe is not important for video configuration/performance)

It would be nice if someone could explain the MTRR fix in simple terms. I got a bit lost on those links. The other tweaks worked fairly well but i still get some tearing and slowness particularly with HD video. I'm using this graphics card.....

You didn't give enough information to help you. What you need to do is check the check the memory regions of your graphics adaptor using "lspci -vvnn", and find the "prefetchable" memory range.

Look at this post. In the aforementioned post, the important line in the lspci output of the "VGA compatible controller" section is as follows:

Region 0: Memory at e8000000 (32-bit, prefetchable) [size=128M]

Keep in mind:
128MB = 0x08000000
256MB = 0x10000000

In this example the base memory address is at 0xE8000000, and the memory size is 0x08000000. Therefore, the fixmtrr.sh script contains the line:

echo "base=0xE8000000 size=0x08000000 type=write-combining" >| /proc/mtrr

All you need to do is follow the steps of that post, while remembering to write the correct base memory and size for your system.

Does there exist a PPA that has xserver-xorg-video-intel version 2.7 64-bit for 9.04 (Jaunty)?

I made a script that adds the mtrr entry, and added it to /etc/sudoers so I can perform it without needing a password. Then I just added a symlink in ~/.kde/Autostart and now it gets run even after an X restart.

Lastly, I added that 2.4 repository to get the old driver. And damn. Now I can watch flash again.

Drivers compiled from git semi-daily. Latest is from 22/04. If you want fresher than that, you'll have to compile them yourself (which isn't hard, though).

All launchpad ppas compile packages for i386, amd64 and lpia.
