Re: Arch on Eee PC

Has anyone gotten encrypted drives working with the new kernel?
i'm trying to create an initrd that includes an encrypt hook using
sudo mkinitcpio -g /boot/vmlinuzeee.img -k 2.6.24.4eee
however all i get at boot is:

root (hd0,0)
Filesystem type is ext2fs, partition type 0x83
kernel /vmlinuzeee root=/dev/sda2 ro

Error 13: Invalid or unsupported executable format

so i guess the problem is with my image
"This error is returned if the kernel image being loaded is not recognized as Multiboot or one of the supported native formats"
when i make the image i get these errors at the beginning:
ERROR: module 'ata[-_]generic' not found
ERROR: module 'ahci' not found
ERROR: module 'ata[-_]piix' not found

and my menu.lst looks like
kernel /vmlinuzeee root=/dev/sda2 ro
initrd /vmlinuzeee.img

Re: Arch on Eee PC

I compiled it, but the one i've installed is from the eee repo. i've tried removing everything but the default arch kernel and reinstalling, but at the time it doesn't seem to help. by the way, as long as i am the only one who's having this problem (and i do not need the ethernet device most of the time), this can remain a curiosity.

Just make sure you are really booting /boot/vmlinuzeee kernel and not the generic one from kernel26 package.

initrd /vmlinuzeee.img

At least those ERRORs while creating the initrd image are caused by missing modules which are already built in the kernel-eee so you can safely remove them from /etc/mkinitcpio.conf's MODULES array.

I don't use encryption at all so sadly I can't help you with this but you can at least try running  hwdetect --hooks and update your HOOKS array in /etc/mkinitcpio.conf (don't forget to include the encryption stuff). There's also a possibility that we are still missing some kernel features.

By the way has somebody got the intelfb working? I always end up with "intelfb: Cannot reserve FB region." error.
I have been running some tests with all three framebuffer drivers and it seems that only special feature with the uvesafb is native 800x480 resolution but that can't be done without 915resolution-tweak and uvesafb built as module.
So for now I suggest removing the intelfb from the kernel (less annoying errors at the boot time) and compiling uvesafb as module. General vesafb driver is working just fine. :E

Re: Arch on Eee PC

i've installed v86d and used the vga option of 640x480  at 256 colors in grub. what i got is a black screen after grub until x starts.

@ighea: yes i'm sure i'm booting the right kernel, otherwise i would have a different output on uname and i could modprobe the modules that are no longer built in, right?

Yes, we are still missing the framebuffer console support I mentioned before.

@ighea: yes i'm sure i'm booting the right kernel, otherwise i would have a different output on uname and i could modprobe the modules that are no longer built in, right?

Well, you are at least having really strange errors there. I hope reinstalling the kernel-tuff would fix them, but dunno.

Re: Arch on Eee PC

UPDATED: acpi-eee-8-1

Here is once again amazing update for one of the best acpi-script packages available!
http://kapsi.fi/~ighea/eee/acpi-eee/acp … pkg.tar.gz

So what's new in this release?

* In /etc/acpi/eee.conf
** one can now specify screen position for the asusosd (I always thought the left top corner was weird >p)
** set optional commands to be run once wlan is turned on/off with Fn-F2
* minor tweaks in wlan.sh

Tip: As the wlan on/off scripts something similar to http://kapsi.fi/~ighea/eee/wpa can be used if you use wpa_supplicant for you wlan management.

If you happen to have any improvement ideas feel free to tell them!

Wow, nice update ighea!

Will try this out as soon as I can.

PS. Is there a way to have my screen turned off when closed the lip instate of suspend?

Sure, just set COMMAND_ON_LID_CLOSE=yes to COMMAND_ON_LID_CLOSE=no.
Make sure you have the XUSER entry set and turning off the screen should work just fine.

This is great,  Is it possible to have lid closure do different actions depending on power status (if ac on turn off screen, if ac off turn off eee)?

Does anyone have any suggestions on a battery monitor app?  I would also like something to give me low battery warnings and maybe even be able to issue a power down command when power gets to a certain level.  I have tried several apps with no luck.

Also, I have been trying to get a bluetooth headset working.  I read the wiki but was unable to load snd-bt-sco.  It would really cool to get this working.

Thanks

At this point it is best to start writing your own acpi event handlers- then you can do most of this kind of stuff. Take a look at ighea's and I's acpi scripts (mine are still not in an 'official' package but they are in my GIT repo) to see how to do this sort of thing.

Re: Arch on Eee PC

Ok i got toofishes kernel to boot sorta but when i get to the "enter luks passphrase:" part and enter my password it says

device-mapper: table: 253:0: crypt: Error allocating crypto tfm
device-mapper: ioctl: error adding target to table
device-mapper: ioctl: device doesn't appear to be in the dev hash table.
Command failed: No key available with this passphrase.

The fallback image with the stock kernel still boots fine. Can anyone guess whats going on here?

Here's acpi-eee-8-2 with new ON_AC_LID_CLOSE_ACTION and ON_BATTERY_LID_CLOSE_ACTION variables which can be used just like you wanted.
See /etc/acpi/eee.conf for more details.
http://kapsi.fi/ighea/eee/acpi-eee/acpi … pkg.tar.gz

For battery monitoring I use gkrellm and gnome-power-manager. Gkrellm is much more than just a battery monitoring app, but it can be used only for that. You can also specify warning and alert states/messages in it.
The gnome-power-manager is mosty only for show because one can't specify low and critical battery status values or at least I couldn't find anything useful with geconf-editor. :E

Are you sure that the driver really is "snd-bt-sco" and not just "sco"? I think you should try out that one, if you have not already.

Re: Arch on Eee PC

xfce4-battery-plugin with xfce4-panel. You can juste have a window to popup when your battery is running low, or you can execute a specific command.

For those who want to play (don't know if there's many here), juste download the PKGBUILD for wesnoth on AUR (devel version, the one in community is outdated), Add "--enable-smallgui" and you'll be able to launch the game in 800x480

Now I will update my acpi-eee, thank you ighea !

Crypto works perfectly fine here, maybe the algorithm you used for encrypting your partition isn't in twofishes kernel? Try comparing zgrep CONFIG_CRYPTO /proc/config.gz from twofishes kernel with the stock kernels config.

How do i test that command against toofishes kernel? i can run the command but i can only boot using stock kernel. Assuming i figure out a way to test this can i use the results to fix this myself or is this just a test to see if need to start over again using supported encryption? (if its the latter then could you let me know which algorithims ARE supported?)

for reference i encrypted using the algorithms specified in the luks wiki here.

Thanks for pointing me in a direction! can't wait to get back on toofishes kernel again!
Any additional help is still much appreciated thanks!!

Thanks but i just wiped and encrypted with aes256 so now everything works perfect. turned out lrw wasn't supported by your kernel. But no matter, every install has been a learning experience. thanks for the help guys

Thanks ighea!!

This is exactly what I wanted.

I tried gkrellm but did not like it and I'm now using gnome-power-manager for now.
However I am taking toofishs advice and  I'm trying to make a acpi battery event.  This is what I have so far:

In /etc/acpi/events/battery

event=battery.*
action=/etc/acpi/battery.sh

In /etc/acpi/battery.sh

#!/bin/sh
if grep -q on-line /proc/acpi/ac_adapter/AC0/state; then
  exit 0
  fi
  
  BAT_DIR=/proc/acpi/battery/BAT0
  FULL_BAT=`grep 'last full capacity' ${BAT_DIR}/info | awk '{ print $4 }'`
  CUR_BAT=`grep 'remaining capacity' ${BAT_DIR}/state | awk '{ print $3 }'`
  AVG=`expr $(expr ${CUR_BAT} \* 100) / ${FULL_BAT}`
  
  if [ "$AVG" -le "90" ]; then
    /usr/bin/showbatt
    fi

Wright now battery.sh seems to works, it will call showbatt (part  of osdbattery) only when ac is off line and battery is below 90%

I just cant get it to work as an event, nothing happens.

This seems like this should be easy but I'm new to scripts and acip.  btw, I did not make these scripts I just found them and adjusted them. 

I know the script needs work but I think this might be great way of having low battery warning while running a light weight desktop.

Thanks,
brncmp

Re: Arch on Eee PC

Am I the only one to have trouble with toofishe's trick concerning alsa & shutdown?

It was working fine a few days ago, but since a fresh install, the system is simply freezing at shutdown (hanging at "the system is going to halt NOW!"), and the only solution is to hold the power button, which of course produces inconsistent fs at reboot.

[eko@nodrom ~]$ cat /etc/rc.local.shutdown
#!/bin/bash
#
# /etc/rc.local.shutdown: Local shutdown script.
#

#/etc/rc.d/alsa stop #tried with and without this line: same results.
echo -n "0000:00:1b.0" > /sys/bus/pci/drivers/HDA\ Intel/unbind

I think the pci bus is the same:

[eko@nodrom ~]$ lspci | grep Audio
00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 04)

I've also tried to execute the echo -n... command before halting and after stoping alsa, but without succes, the system is still hanging at shutdown.

that doesn't work for me too. actually my eee shuts down normally most of the times, but freezed with that command.

Re: Arch on Eee PC

In latest version of acpi-eee, file suspend2ram.sh, I suggest to save current vt instead of always switching to 7th:

        # change virtual terminal to not screw up X
        vt=$(fgconsole)
        chvt 6

...

        chvt $vt #Back to old vt

I'll do something about that soon.

And there's a new bios version 910 available: http://forum.eeeuser.com/viewtopic.php?id=21711 .

@toofishes:
could you please set CONFIG_FRAMEBUFFER_CONSOLE=y in the eeepc kernel? It is required for uvesafb to work.
