Acer Aspire One

ilLorenz · 2008-12-26 16:43:56

hello...I never used arch before, and I've been trying to install archlinux on my AA1 the last few days, rather unsuccessfully... Now what I'd like to do is try Gothick's custom kernel, and my question is, is there a way to install it *during* the installation process, so that I can select it as the only kernel to be installed? I have tried before, but when I attempt to install it on a fresh installation I get many "already exists in filesystem" errors, which I tried to ignore with `pacman -f' but it didn't end well.... Somewhere in the wiki it is suggested to use `pacman -r /tmp/install kernel26-one', is this the correct way to do it?
I am sorry if the question has already been answered, the topic is 30 pages long and I probably missed that bit! ;-)
Thank you.

Yes, search this topic of ours...gothicknight provided a binary package for his custom kernel...download it and put it to you flashdrive. The downloading can be done via another computer...

After that, mount your fd. Search for the custom kernel...

pacman -U /path/to/your/fd/kernel26-one....

The kernel will be installed and you have to add it to your /boot/grub/menu.lst

#Custom kernel
title Arch Linux (kernel26-one)
root (hd0,0)  #if you had arch on that partition..
kernel /boot/vmlinuz-one root=/dev/sda1 ro

just check if your partitions corresponds to mine...:)

Anyone here using the latest kernel 2.6.28?

kaola_linux · 2008-12-27 09:45:17

Anyone here using the latest kernel 2.6.28 on their AA1? I'm looking forward to gothicknight's release of the kernel26-one 2.6.28 coz I'm no expert at kernel hacking yet...:P

I'm sorry for the double post, I had a mistake....:(
Gudluck!!!:)

I tried that, but as I said I got several file conflicts error (like "file already exists in filesystem") which prevented me from installing the kernel that way. To complete installation I had to force pacman with

pacman -Uf kernel26-one

but, since I never used pacman before, I doubt that is the correct way to do it. Plus, after doing that, I got several "fatal:module not found" errors at boot. So, is there any way to install the kernel *before* the installation is complete*?
Any pointers welcome, thanks!

Yes, you did it the correct way. Sometimes due packaging mistake, you have to force an upgrade with the -f switch. This is, of course, not recommend but is really the only way to overcome conflicting file errors.

I'm getting those errors as well but it doesn't seem to affect me at all so I haven't really cared to search what is the cause. Did your laptop boot up fine with the kernel, besides those module errors?

ichbinesderelch · 2008-12-27 12:13:59

i compiled kernel 2.6.28 for aa1 with sd-hd, since now up and running pretty good, if anyone wanna try it out
config http://mitglied.lycos.de/ichbinesderelch/config
PKGBUILD http://mitglied.lycos.de/ichbinesderelch/PKGBUILD
build without madwifi, not sure if working for the hdd version as well, better wait for gothicknights release

kaola_linux · 2008-12-27 12:26:12

I to have encountered those errors...What I did was delete each of them...It worked...Now I am using the kernel26-one..Helps shorten the bootup process because there are no modules to load at startup...Thanks gothicknighg!!!:D

Tera · 2008-12-27 13:35:57

Here is my slightly modified 2.6.28 kernel for you to try.

You can snatch the ready to "pacman -U"'d binary package from http://dolly.rulex.net/~giga/arch/kerne … pkg.tar.gz
Config is available at http://dolly.rulex.net/~giga/arch/config.kernel-2.6.28
No modifications done to the PKGBUILD, except version bump and the removal of Madwifi as it doesn't seem to compile and I don't have the energy to debug it more at this time.

Now the main differences from gothicknighg's official kernel26-one package are:
Ext4 filesystem support compiled in as module
Bluetooth support compiled as static
No Madwifi. WLAN is however working fine for me. Although I haven't had the possibility to test it with WEP/WAP.
Ethernet seems to be working fine. Someone has said that the BIOS version 3309 might have fixed some LAN troubles. I'm running 3309 myself as well, with gigabit network switch if it matters.

As ichbinesderelch said, you should probably wait for gothicknight's release

EDIT: I forgot to mention that I have kexec enabled this kernel as well. If you don't know what it is, and want to read more, check out http://www.ibm.com/developerworks/linux … kexec.html

There is this part on the AA1 wiki about "setting a proper framebuffer"

I've done it but it is for the stock kernel. Any ideas how to do it on the kernel26-one instead?:)

thanks...

additional: Anyone managed to turn the led on/off on their AA1 using arch?

It works the same way, you just have to adjust the mkinitcpio line to create an initramfs for kernel26-one. Read the man-page of mkinitcpio on the -k and -g options and be sure to adjust the initrd line in /boot/grub/menu.lst corresponding to your initramfs. However, one main advantage of kernel26-one is that you need no initramfs. You would have to use one just for uvesafb.

Zom · 2008-12-27 22:14:03

I've posted instructions on how to do it in this very thread quite recently kaola_linux, check this post.

gothicknight · 2008-12-27 23:30:54

Sorry about the lack of news. The holidays have got me even more work

I hope Monday I can make a release.

kaola_linux · 2008-12-28 09:04:08

Guys, good news!!! I've managed to connect to a wifi network..I'm using it now while posting it here...I've tried archassistant but it was not that succesful...Trying wicd, it worked flawlessly!!!Cheers...
I'm using gothicknight's kernel26-one...:lol:

This was helpful Zom..thanks alot..

I've posted instructions on how to do it in this very thread quite recently kaola_linux, check this post.

# (0) Arch Linux
title Arch Linux One [/boot/vmlinuz-one]
root   (hd0,0)
kernel /boot/vmlinuz-one root=/dev/sda1 ro vga=789 quiet elevator=deadline usbcore.autosuspend=1 splash
initrd /boot/kernel-one.img

What's the the purpose of

elevator=deadline and usbcore.autosuspend

?:)

Will this improve performance of the ssd? I've seen a tweaking guide for the linpus lite and it was stated to include

elevator=noop

on the menu.lst...:)

Thanks..:)

i'm assuming you don't have the flash version then? You shouldn't be using a journalled filesystem with flash.

Also xfs is after reiser4 the most cpu heavy of the filesystems. You really don't have a lot of extra cpu to play with on a netbook. I'm running ext2.

I really wish nilfs2 were further along, I really think that would be the choice for SSDs. Any way to add nilfs2 to kernel-one ?? (probably not likely as it's not production ready as far I know).

Thanks on the info bnolsen, I'll keep an eye in nilfs2 but this is still in development and only ready to 2.6.27 AFAIK (thank god they didn't pick "Modern" to "New" in NILFS2 )

Anyway... kernel26-one is right now under compiling and after some tests I hope I can release the first draft of it.

As I cannot follow every change in the kernel this days, if anyone has found a new feature added in 2.6.28 that would benefit all of us, please post it here.

UPDATE: Madwifi won't compile (v0.10.5.6-r3879-20081204)... I'll have to leave this to tomorrow

I'm using the SSD version..Xfs was one of the 3 fs mentioned on the wiki...Can someone confirm that on ext2 fs the AA1 SSD version do some random pausing?

@Zom: I tried your guide but whenever I do the command it says about "file does not exist"...What should I do?

gothicknight · 2008-12-29 11:33:24

kaola_linux, the SSD versions are really bad for heavy I/O, and when browsing I do experience the system hanging specially when starting firefox. This is ___regardless of the filesystem___ you're using, I for myself would got a better SDHC card with respectable speeds to get some performance.

There was some improvements to firefox so it would be more gentle in the I/O a "few" posts back though.

kaola_linux · 2008-12-29 13:44:57

So it's just ok to use xfs? Just like you I had problems with firefox as well...Now I'm using opera and my browsing with the AA1 improved...:)

gothicknight: do you have any ideas on how to set the proper framebuffer on the AA1? I have tried what's said on the wiki on the stock kernel but to your customized kernel I don't know how..:( Zom, posted about this but I had problems...

Does including the "elevator=noop" on your menu.lst helps?

Thanks to all...:)

gothicknight · 2008-12-29 14:16:50

I've been using XFS in my /home for integrity reasons and changed to ext2 to check if got any kind of performance enhance, it may have gotten better, but no real data to prove that.

I've never encountered/noticed any framebuffer problem... what's the issue?

Using elevator=noop does boost several write or read operations speed but declines severly when using read and write operations when multitasking (stagnation problem) I think a new elevator should be placed, one that handles only starvation issues and ignores sector awarness, the closest one right now is the deadline for starvation issues and it is the default in kernel26-one.

Now, for kernel26-one.

Madwifi simply doesn't compile, it's possible to be something that I miss in the Kconfig, but as the madwifi site explains the developers are now focused in ath5k so for this release I'll make ath5k inkernel and drop madwifi, at least for now.

Also, I've also put ext4 as a module now, although I think there isn't still support for it in GRUB package to use it as root filesystem, I for once will try it in my /home partition

kaola_linux · 2008-12-29 14:22:19

I mean the "Setting a proper framebuffer" it was located on the AA1's wiki...I wish to apply it to your kernel26-one as well...I'm glad your online now...:D I'm looking forward to your latest release...

do you have any idea how to make the wifi led work on arch? It does function but there is no light on the led...;)

Thanks

thomasd · 2008-12-29 19:33:46

I did provide the answer to your framebuffer question above. You have to modify the mkinitcpio step. Probably nobody using kernel26-one is using uvesafb as it requires an initramfs. You will have to do some research on your own if nobody has done it. Posting the same question four times does not help here.
If you search on the wiki for "custom kernel" and "mkinitcpio" you will probably find the answer. If you solved it, post it to the AA1 Wiki entry to help others.

The Wifi LED is not working with ath5k. It does with madwifi with some additional rc.local entries posted somewhere in this thread.

Zom · 2008-12-29 23:14:25

@kaola:
The "elevator=deadline" was a tip I picked up somewhere for boosting the performance of the SSD, I think it works better than noop.
The usbcore.autosusped was a tip I got from powernowd on how to improve battery lifetime.

What file doesn't exist by the way? Which command fails?

Also, I can confirm that both wired, wireless and 3G modem works with gothics kernel and networkmanager >7. You could try updating the networkmanager packages from the testing repository.

@gothicknight:
If the latest madwifi doesn't compile, why not try the second latest?

Second latest!?

I've already uploaded it to my usual FTP but haven't tried yet on my own AA1 sorry folks
