Netbook performance tip; Install kernel 2.6.30 or 2.6.31

Update: For those interested in the 2.6.31 kernel, the files can be found here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.31/

Download and install (in that order):

linux-headers-2.6.31-020631_2.6.31-020631_all.deb
linux-headers-2.6.31-020631-generic_2.6.31-020631_i386.deb
linux-image-2.6.31-020631-generic_2.6.31-020631_i386.deb

------------------------------------------------------------------------
Kernel 2.6.30 comes with a new intel graphics driver that has better performance than the 9.04 defult. More info and tech stuff can be found on google. I have no numbers to confirm the performance increase but I do feel as if flash (youtube etc.) runs smoother with less hickups. I recommend this to Atom Netbook users.

1. Go to this page: http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.30/

2. Download the following files to any location:

linux-headers-2.6.30-020630_2.6.30-020630_all.deb
linux-image-2.6.30-020630-generic_2.6.30-020630_i386.deb

3. Install the files by doubleclicking them or selecting them from the menu. Start with "linux-headers..."

4. Reboot and confirm update by typing "uname -a" in a terminal window. 2.6.30 should be visible in plain text.

Enjoy the performance boost smile

GL!

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

Nice.  Just upgraded my Eee 901 running  #! 9.04.01.  Have no comments on performance yet, but noted that I had to download and install linux-headers-2.6.30-020630-generic_2.6.30-020630_i386.deb to get the eeepc_laptop module to load.

So far so good.

cheers,

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

Hi, I just installed 2.6.30 on my Dell Mini 9, but my wireless (Broadcom wl driver) is no longer detected... any tips how to get it working with the new kernel?

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

for the mini 9 you'll need the restricted modules package as well. The broadcom card ended up being too much of a hassle for me and I just swapped it out for an intel, pretty easy to do and was only about 30 bucks if it's something you wanna look into.

just looked into it some more, apparently the modules will no longer be in restricted modules, they will be compiled by dkms. Try getting bcmwl-kernel-source.

Just installed on my 901. Booted fine, but my hotkey for changing CPU-Speed does not work anymore (have elmuratos script installed...) Do the 4 special keys work automatically, so that I should remove elmuratos... ?

@snowpine and Kuno: I never noticed any differences after installing the new kernel so I did not bother to "warn" people of what could happen if you decide to install. Will fix this, sorry that you are experiencing issues.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

OK, I got Broadcom wireless working on my Mini 9 with kernel 2.6.30.

Not wanting to spend a lot of time researching this, I decided to try the same solution that had previously worked for me in Debian. I simply followed the instructions in the first post of the following thread: http://forums.debian.net/viewtopic.php?f=16&t=30648

The only problem so far is that Network Manager wasn't smart enough to know eth1 was wireless. So I simply installed Wicd (which I might have done anyway) and changed its preferences so the wireless interface is eth1.  Also I added 'wl' to /etc/modules so it is loaded at boot.

Hope that helps my fellow Dell Mini/Broadcom users. smile

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

I dont know, but they should smile I need someone to confirm this, but I think you can configure grub to boot your old kernel if the new one dont behave. Just press Esc at boot.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

In my case, Ubuntu 9.04 doesn't recognise my Ati drivers. (Damn org)
Neither does it boot on my desktop PC. (Live 9.04)
That's why I've switched back to Crunchbang 8.10 at my laptop. Though it doesn't recognise the webcam on my Laptop, the ATI does work.

What I wonder is, is it due to just Xorg 1.6 or does this new kernels has anything to do with it?
(Still a newbie)

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

slight hijack...

Think its worth it to install on a ancient Compaq C500(Celeron 500mhz, 512mb ram,  Broadcom 4306 wifi running #!9.04 kernel 2.6.28-13)? I dont need most of the new features(link below) because performance/speed is good enough, but browsing FF/Swiftfox hit the CPU hard(even with ABP/No Script)... so if the new kernel helps alleviate that(maybe better management), it may be worth it for me.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

Hi all,

i've been using Debian sid with lastest kernels last six months in order to obtain better performance of intel graphics card (i own a Samsung NC10). It's extremely unstable code yet, and sometimes is subject of regresions in performance, but in general after 2.6.30 was released i could say it's quite acceptable user experience, though sometimes an upgrade of intel's driver led my desktop unusable with 2.6.20 and KMS/UXA enabled. It's also necessary to update to latest Xorg intel driver (i think 2.8 now, and #! has 2.6) and force X server to use UXA acceleration method and maybe disable tiling. Now i'm giving a try to this nice distribution (never would say it's ubuntu based!) and i'll post my results with this kernel you recommended, but without latest intel driver, it's not a recommended configuration.

See you

PS: Also enabling KMS disables backlight control, and desktop tools are unable to change it. However, there's a workaround using setpci command.

Kdawgca:

I browsed for you laptop, and if yours has this card

Intel GMA 950 integrated graphics

it is one of the supported chipsets.  However, i don't know if it is yet a good option, but you can give it a try.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

if the new kernel doesn't behave, just delete it with dpkg -r or apt-get remove. If menu is hidden, need to press ESC to be able to select other entry. If you want to keep the newly installed kernel, grub has a option "default" which sets the default menu entrance to boot from (starting form 0) in /boot/grub/menu.lst
murak, do you know of repositories with the newest X server packages for ubuntu?
Thanks

Thank you for the information, micerinos. No, I dont know of any repos with the newest x server. But please do post if you know something. Anything that will up the performance is good smile

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

New kernel behaves correctly in NC10, but no KMS/GEM by default. To check it

cat /sys/module/i915/parameters/modeset

Also need to activate UXA explicitely in /etc/X11/xorg.conf

Section "Device"
        Identifier      "Configured Video Device"
        Option          "AccelMethod"           "UXA"
        Option          "Tiling"                "No"     # It was a workaround for a bug, should be solved as of 2.6.30
EndSection

Although without KMS doesn't make many sense. You can check it in Xorg logs. Tried to activate it by rebuilding initramfs and sistem hangs on loading X. Tried passing parameters to module i915 in /etc/modprobe.d/i915.conf (need to create it)

options i915 modeset=1

and system also hangs on loading X. None of the methods finally activated KMS. Now i'm recompiling kernel to build-in intel_agp, drm and i915. As i never compiled a kernel for Ubuntu, don't know if debian way will do the trick. I'll post my advances...

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

you could try kernelcheck http://kcheck.sourceforge.net/ . It makes compiling the kernel a lot easier.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

How can I install the linux-source packages of the main line kernel?
Downloading the .deb and installing neither via gdebi nor dpkg will work, it says it's installed, but dkms keeps telling it cannot be found.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

After installing the kernel, you have to reboot, go into the GRUB menu (ESC button) and choose the new kernel.

Thx for the post. Unfortunately, The C500 is also a really old desktop(deskpro EN series) which is the variant I have. GMA950 would suggest a Intel 945 chipset(way too new for a computer with a 500mhz processor)...

My Celeron 500mhz(Mendocino family most likely) would indicate a Intel 810 chipset, so I would have an older integrated GPU(specs say 4mb/8mb so IDK if they even named it back then).

Anyways, I now have a decent browsing experience thanks to Opera 10 beta and modified host files(to take care of the cpu hungry flash ads/fast page load), so I can put the new kernel on the backburner.

Re: Netbook performance tip; Install kernel 2.6.30 or 2.6.31

Hi all,
finally got it working! I recompiled the kernel (the debian style works perfect in ubuntu, but thanks for the link iggykoopa) and had to install newest Xorg intel driver version. Is it possible to upload here the kernel packages? If not, i'll try to upload to my university during the week. They are supposed to work mostly in atom based machines. The basic procces is as follows:

- Download and install the hearders and kernel (need to upload yet, sorry!)
- I would recommend a reboot in single user to check if all hardware is recognized (i remove some unnecessary stuff for atom based) If it is not the case, just delete it.
- Edit your /etc/apt/sources.list to include this repository

deb http://ppa.launchpad.net/xorg-edgers/ppa/ubuntu jaunty main

- Install the key of the repository, update and upgrade. This will install newest intel driver (2.8)

apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 165d673674a995b3e64bf0cf4f191a5a8844c542
apt-get update
apt-get upgrade

- Edit your /etc/X11/xorg.conf to include

Section "Device"
    Identifier    "Configured Video Device"
    Driver         "intel"
    Option          "AccelMethod"           "UXA"
EndSection

And that's all. As expected, backlight control is lost, but the following command can solve it:

setpci -s 00:02.1 F4.B=XX

as root, where XX is a hexadecimal value (00-FF).

I'll let you know when i upload the packages. Also, recommend reading this page about intel graphics in ubuntu to decide your best option. For me this combination works very good (we'll see how stable it is!)
