HOWTO: Jaunty Intel Graphics Performance Guide

......
And fullscreen flash video still goes ugly...

Also X.Org constantly consumes 25-30% of CPU. User interface is very slow (I used Gnome and now use Xfce). When I reboot my laptop, this problem is temporary solved, but then it goes high again after some period of time.

Finally, I added the next lines to kernel boot options:

enable_mtrr_cleanup mtrr_chunk_size=256M mtrr_gran_size=256M

And after reboot /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=0x0c0000000 ( 3072MB), size=  256MB, count=1: write-back
reg03: base=0x100000000 ( 4096MB), size= 4096MB, count=1: write-back
reg04: base=0x200000000 ( 8192MB), size= 8192MB, count=1: write-back
reg05: base=0x400000000 (16384MB), size=16384MB, count=1: write-back
reg06: base=0x0e0000000 ( 3584MB), size=  256MB, count=1: write-combining

And Flash fullscreen video goes smoothly! So the problem is solved.

Yes, that's Linux way - spent a lot of time to solve issues that Windows users do not have at all

BTW, there is a bad effect also: now system detects only 3355 MB...

i followed the steps to update the kernal, but it still says i have 2.6.28.15... im fairly new, but not brand new here. It still works the same, but not better.... any1 know why i dont have the most recent kernal?

I used the Optimal instructions

This sounds like perhaps you have inadvertently installed the 32-bit kernel rather than the 64-bit kernel.

When you say "it" says you have 2.6.28.15, what do you mean by "it" exactly? What is the output of the

uname -a

command? Did you get any errors when you performed the steps in part C? What is the output of

dpkg -s linux-image-2.6.30-02063003-generic | grep ^Status

? If it says "Status: install ok installed", what is the output of

cat /boot/grub/menu.lst | grep "^title\|^default"

?

I installed the "Safe" method and it wasn't safe. Ubuntu is now EXTREMELY laggy and sluggish; it's effectively unusable. It took me ~five minutes to navigate to this page, and then I just gave up and booted into Windows. I'm using the Intel 965 chipset. Does anyone have any idea what this is related to? I searched the thread and found nothing.

(This isn't what "tiling" would do to an 800 series, is it? I did everything exactly as it said for the "Safe" method and enabled tiling.)

Your chipset may still have performance regressions with UXA, or may required the newer kernel modules from the 2.6.30 kernel onwards to perform properly (which is equivalent to the Optimal configuration).

Make sure you read the guide properly - there are instructions to revert changes.

it says it is not installed...

2.6.28-15-generic #49-Ubuntu SMP Tue Aug 18 19:25:34 UTC 2009 x86_64 GNU/Linux

and

Package `linux-image-2.6.30-02063003-generic' is not installed and no info is available.
Use dpkg --info (= dpkg-deb --info) to examine archive files,
and dpkg --contents (= dpkg-deb --contents) to list their contents.

You didn't follow the guide properly, then. Are you aware that for the lines which are prefixed with "$", that symbol only signifies that commands are to be entered in the terminal? In other words, paste the lines without the dollar symbol prefixed.

[FreezWay]

hmm i did it and did not paste the $, i'll try again....
