HOWTO: Jaunty Intel Graphics Performance Guide

[PatrickVogeli]

yeah, sure it is. I have an Intel x3100 (the 965 chipset) and compiz is working fine.

just do the following:

cd
touch .config/compiz/compiz-manager
echo "SKIP_CHECKS=yes" > .config/compiz/compiz-manager

Then go and try to activate compiz again.

Hello again. Still no answers since May. The guide didn't help me.

Now I updated to 9.10, and I have the following kernel & drivers:

Linux oleg-laptop 2.6.31-6-generic #25-Ubuntu SMP Fri Aug 14 16:25:04 UTC 2009 i686 GNU/Linux

oleg@oleg-laptop:~$ dpkg -l |grep intel

/proc/mtrr:

oleg@oleg-laptop:~$ cat /proc/mtrr

reg03: base=0x0de000000 ( 3552MB), size=   32MB, count=1: uncachable

And again, when I try to run fixmtrr.sh, nothing changes.

fixmtrr.sh:

#!/bin/sh
echo "Extracing base address and memory size from lspci -v"

# extract the base address for the video memory
address=`lspci -v \
    | grep -A 7 VGA\
    | grep -F " prefetchable"\
    | awk 'BEGIN{OFS="";ORS=""}
          {print $3
          i = length($3)
          while(i<8){
                  print 0
                   i++
           }}'`

# we extract the memory size as a decimal number from lspci from the correct
# line, we then convert it to hexadecimal and fill it up with the correct
# number of zeroes

hsize=`lspci -v \
    | grep -A 7 VGA \
    | grep -F " prefetchable" \
    | awk '{print $6}' \
    | sed 's/[^0-9]//g' \
    | awk 'BEGIN {OFS = "";ORS=""}
           { printf "%x" , $1
         i = length($1)
         while (i<8) {
             print 0
             i++
         } }'`

echo $address
echo $hsize
echo

# check if the mtrr range has already been set and, if it hasn't, set it up
echo 1
echo "Supplying corrected MTRR ranges to /proc/mtrr"
echo "base=0x$address size=0x$hsize type=write-combining"

Help me please!!! I really love Ubuntu, it works great on my second laptop and on office workstation, but it really bothers me with my Dell laptop...

[bearozo]

I have not found one but there might be one, 845 is the only one on the list now.

I reverted to the 2.4 intel driver to play in ubuntu. This has helped me alot. I only use the windows partition to use my printer or connect to my Blackberry.

According to your stats, you have a 945G chip. I have read success from others. I have to use 2.4 driver, since I have i865 chip. Have you followed this guide completely? Also, what's wrong with your printer? Most work without problems.

I updated my BIOS to the latest one from Dell website (A13)

Then I tried to boot with enable_mtrr_cleanup option, but there were no any changes, and the next messages were in log files:

Aug 21 20:01:16 oleg-laptop kernel: [    0.000000] mtrr_cleanup: can not find optimal value
Aug 21 20:01:16 oleg-laptop kernel: [    0.000000] please specify mtrr_gran_size/mtrr_chunk_size

Next I tried mtrr-uncover, and now my /proc/mtrr looks like:

reg00: base=0x000000000 (    0MB), size= 2048MB, count=1: write-back
reg01: base=0x080000000 ( 2048MB), size= 1024MB, count=1: write-back
reg02: base=0x0ddc00000 ( 3548MB), size=    4MB, count=1: uncachable
reg03: base=0x0de000000 ( 3552MB), size=   32MB, count=1: uncachable
reg04: base=0x0c0000000 ( 3072MB), size=  512MB, count=1: write-back
reg05: base=0x100000000 ( 4096MB), size= 4096MB, count=1: write-back
reg06: base=0x200000000 ( 8192MB), size= 8192MB, count=1: write-back

But I don't see video memory here.. According to my lspci -v it should be "e0000000"

And fullscreen flash video still goes ugly...

Optimal* Configuration

• This configuration is identical to "Safe", but includes the 2.6.30 kernel. Using this kernel will improve 3D performance for many users, but you will lose access to restricted kernel drivers. This configuration yields the best results for my system (an 855GM chipset), but of course, your experience may differ.

A week ago I installed 9.04. I am really enjoying using Ubuntu fulltime on one of my computers. In a way it is freeing not having to rely on Microsoft software.

I wanted to say Thank You for this article. I followed the Optimal Config, and my major issue was resolved.

FYI, the major issue was fullscreen video playback of Flash based video. Specifically, Hulu.com. I followed all the steps for Optimal, rebooted after the kernel install, booted into the 2.6.30xxx kernel, ran Hulu.com, fullscreen LOST S01E01 and w00t! No choppy video.

FYI, 3D performance wasn't my goal as my laptop (Dell Inspiron 6000) isn't that great. Just fullscreen flash video.

THANKS!!!!!!!

I've just ordered a new laptop with an Intel 4500MHD. Does anyone have any experience with this chipset? I'm curious to know which configuration works best with the 4500MHD.

thanks.
