ALL IN 1 HDD Docking (Unitek) in Linux

Vegard — Wed, 26 May 2010 22:31:37 +0000

Since my external HDD`s adapter died and I found out that these Western Digital`s adapters are bad all over through Google. I threw the contoller away and bought a new instead of another faulty adapter. There were little information about this controller, but it has tons of features at a low cost. My main concern was support in Ubuntu, but I found some defuse info about Linux support after some heavy Googling. I gave it a shoot and this post is my blessing for it`s plug`n`play comparability with Linux. I can now use the WD SATA disk and an old IDE disk laying around!

Ubuntu network install (PXE)

Vegard — Sat, 24 Oct 2009 23:11:03 +0000

sudo apt-get install tftpd-hpa tftp-hpa xinetd dhcp3-server sudo pico /etc/xinetd.d/tftp

Then write following
service tftp { protocol = udp port = 69 socket_type = dgram wait = yes user = root server = /usr/sbin/in.tftpd server_args = /var/lib/tftpboot disable = no }

Edit TFTP config
sudo pico /etc/default/tftpd-hpa

Make it look something like
#Defaults for tftpd-hpa RUN_DAEMON="yes" OPTIONS="-l -s /var/lib/tftpboot"

Create TFTP directory and get latest netboot image
sudo mkdir /var/lib/tftpboot cd /var/lib/tftpboot sudo wget -np -r http://archive.ubuntu.com/ubuntu/dists/karmic/main/installer-i386/current/images/netboot/ sudo mv archive.ubuntu.com/ubuntu/dists/karmic/main/installer-i386/current/images/netboot/* . sudo rm -rf archive.ubuntu.com

Now restart TFTPD
sudo /etc/init.d/tftpd-hpa restart

To check if running@
netstat -uap

For DHCP, make sure you have a fixed ip for your device
pico /etc/dhcp3/dhcpd.conf

I did use firestarter as a DHCP generator since I used my desktop as PXE-server.

# DHCP configuration generated by Firestarter ddns-update-style interim; ignore client-updates; authoritative;

subnet 192.168.66.0 netmask 255.255.255.0 { option routers 192.168.66.9; option subnet-mask 255.255.255.0; option domain-name-servers 130.67.60.68, 193.213.112.4; option ip-forwarding off; range dynamic-bootp 192.168.66.10 192.168.66.20; default-lease-time 21600; max-lease-time 43200; next-server 192.168.66.9; # important for PXE filename "pxelinux.0"; # important for PXE }

After the DHCP change we must restart DHCP
sudo /etc/init.d/dhcp3 restart

You should now be able to boot PXE of this machine.

Ubuntu 9.04 on MacBookPro5,3

Vegard — Thu, 20 Aug 2009 20:56:30 +0000

How I installed Ubuntu Jaunty Jackalope 9.04 on my MacBook Pro 5,3.

After you have installed Ubuntu on your MBP and connected to internet. We need to add some lines in sources.list to be able to get special packages developed for apple products.

WARNING: be carefull with all the ” when pasting, they tend to change into a similar sign!

Update
echo deb http://ppa.launchpad.net/mactel-support/ubuntu jaunty main | sudo tee -a /etc/apt/sources.list echo deb-src http://ppa.launchpad.net/mactel-support/ubuntu jaunty main | sudo tee -a /etc/apt/sources.list sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 7A6BC20C4FE04DADD10837608DB7F87A2B97B7B8 (DONT WORK)

sudo apt-get update sudo apt-get upgrade

REBOOT (recommended)

Get hardware packages
sudo apt-get install mbp-nvidia-bl-dkms applesmc-dkms hal-applesmc bcm5974-dkms lm-sensors

Reboot if you want it to work right away or just continue below.

Keyboard
Apple keyboard backlight and Fn-keys should now work.
If you want to change the fn-usage buttons.

echo options hid_apple fnmode=2 | sudo tee -a /etc/modprobe.d/hid_apple.conf sudo update-initramfs -u

I like to use gnome-do and usually use the Menu key for this. You will be prompted for next login, make sure you load the file.te
keycode 252 = Super_R echo keysym Super_R = Menu | tee -a .xmodmaprc

If you`re having problems getting the $ or brackets (and more) we need to do edit your keyboard layout. Go to Gnome menu -> preferences -> keyboard -> layout and change keyboard model to apple and make sure you have the right layout selected.

Sensors
For using sensors and fans we need to load apple modules:

echo coretemp | sudo tee -a /etc/modules echo applesmc | sudo tee -a /etc/modules

Reboot (optional).

Caps lock
By default the green caps-lock does not work. ItÂ´s a easy fix.

sudo apt-get remove mouseemu

Monitor
If you don`t like the way your MBP auto dim your screen, you can disable it.

gconftool -s /apps/gnome-power-manager/ambient/enable -t bool false

Touchpad
To get multitouch we need to do a little trick.

echo bcm5974 | sudo tee -a /etc/modules echo usbhid | sudo tee -a /etc/modules echo blacklist usbhid | sudo tee -a /etc/modprobe.d/blacklist.conf

Open /etc/hal/fdi/policy/x11-synaptics-bcm5974.fdi and paste.
sudo gedit /etc/hal/fdi/policy/x11-synaptics-bcm5974.fdi

Reboot (optional).

Sound
Follow this recipe and your sound should work.

sudo apt-get install linux-headers-generic linux-image-generic linux-restricted-modules-generic wget ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/snapshot/alsa-driver-unstable-snapshot.tar.gz tar xf alsa-driver-unstable-snapshot.tar.gz cd alsa-driver-unstable sudo ./configure --enable-dynamic-minors --with-cards="hda-intel" --with-oss sudo make sudo make install cd .. sudo rm -rf alsa-driver-unstable alsa-driver-unstable-snapshot.tar.gz

REBOOT (recommended)

Now, donÂ´t forget to unmute sound channels.

If youÂ´d want a automatic fan program, I wrote one in bash. It requires lm-sensors (installed above) to work. I will write it in C some day.
#!/bin/bash

# we don`t want to go all the way up to critiacal temp, safe_temp is substracted from critical temp SAFE_TEMP=10


# AUTOMATIC VALUES BELOW, DON`T EDIT
# CPU critical temp

CPU_CRIT=`cat /sys/devices/platform/coretemp.0/temp1_crit`

FAN1_SPEED_MAX=`cat /sys/devices/platform/applesmc.768/fan1_max`

FAN2_SPEED_MIN=`cat /sys/devices/platform/applesmc.768/fan2_min`

FAN2_SPEED_MAX=`cat /sys/devices/platform/applesmc.768/fan2_max`

CPU_CRIT=`expr "(" "$CPU_CRIT" "/" 1000 ")" "-" "$SAFE_TEMP"`
echo 1 > /sys/devices/platform/applesmc.768/fan1_manual

echo 1 > /sys/devices/platform/applesmc.768/fan2_manual
# dynamic values

while [ 1 ]; do
# CPU TEMPS

CPU_TEMP0=`cat /sys/devices/platform/coretemp.0/temp1_input`

CPU_TEMP1=`cat /sys/devices/platform/coretemp.1/temp1_input`

CPU_TEMP=`expr "(" $CPU_TEMP0 + $CPU_TEMP1 ")" "/" 2000`
# calculate

FAN_SPEED=`expr "(" $CPU_TEMP "-" 34 ")" "*" 200`
# if CPU reaches critical - SAFE_TEMP, shut off

if [ "$CPU_TEMP" -gt "$CPU_CRIT" ]; then

shutdown -h now

fi
# don`t go below min limit

if [ "$FAN_SPEED" -le "$FAN1_SPEED_MIN" ]; then

FAN_SPEED=$FAN1_SPEED_MIN;

fi
# don`t go above max limit

if [ "$FAN_SPEED" -gt "$FAN1_SPEED_MAX" ]; then

FAN_SPEED=$FAN1_SPEED_MAX;

fi
# only write if speed has changed

if [ "$FAN_SPEED" != "$FAN_SPEED_OLD" ]; then

#echo $CPU_TEMP $FAN_SPEED

echo $FAN_SPEED > /sys/devices/platform/applesmc.768/fan1_output

echo $FAN_SPEED > /sys/devices/platform/applesmc.768/fan2_output

fi
# store old speed

FAN_SPEED_OLD=$FAN_SPEED;

sleep 5 done

Pommed
If you would like to install pommed on this machine at this time we have to modify pommed. I have notified creator of pommed about macbook5,3 support. If you have version above 1.27 you can skip this how to.

wget https://alioth.debian.org/frs/download.php/3084/pommed-1.27.tar.gz tar zxf pommed-1.27.tar.gz cd pommed-1.27/pommed/ pico pommed-mpb5,3.patch

Then paste following.
--- pommed.c-old 2009-08-22 20:23:21.796989322 +0200 +++ pommed.c 2009-08-22 20:22:42.270020918 +0200 @@ -677,6 +677,7 @@ * MacBook Pro 13" (June 2009) */ else if ((strcmp(buf, "MacBookPro5,1") == 0) || (strcmp(buf, "MacBookPro5,2") == 0) + || (strcmp(buf, "MacBookPro5,3") == 0) || (strcmp(buf, "MacBookPro5,5") == 0)) ret = MACHINE_MACBOOKPRO_5; /* Core Duo MacBook (May 2006) */

Now apply the patch
patch -p0 < pommed-mpb5,3.patch

Install required packages
sudo apt-get install pommed libdbus-1-dev libalsa-ocaml-dev libaudiofile-dev libconfuse-dev libpci-dev

Compile
cd .. make pommed sudo cp pommed/pommed /usr/sbin/pommed

Reboot.

Download youtube/flash in Ubuntu (Linux)

Vegard — Fri, 05 Jun 2009 20:31:20 +0000

Ever seen a cool movie on the Internet? embedded in flash, unable to download it? who haven’t..

Solution is quite simple and here is it quick for you: Open a page with flash. Wait till it’s completely downloaded, then fetch if from /tmp/.

A longer explanation would be to a youtube page and load the entire movie like so:

When you see the movie has loaded fully, without interruptions from the user (you). You can find it in /tmp/:

Now you just copy it to where ever you’ll like. If you want to convert it, you can open it with avidemux or Kino and then export it to .mpeg or whatever format you’d want.

Using ffmpeg:
ffmpeg -i "/tmp/Flash8CRIFL" "mechanical hand.mpeg"

HP Photosmart C4380

Vegard — Sat, 09 Aug 2008 22:54:06 +0000

Got my new printer today. Shortly after unpacking it I hooked it up and setup it on my windows-partition. Basically because I didn’t have time to see if HP or anyone else had setup software for it on Linux.

The cool thing about this cheap printer is WiFi. It has WLAN which can be turned physically on/off. After it was connected to my network, I did like 5 mouse-clicks and the printer was wirelessly installed in Ubuntu.

Scanning did also work (in Ubuntu) wirelessly, which was pretty cool. It’s a joy to see Ubuntu managing these things just as good and in my opinion; easyer than windows.

Thumbs up for HP Photosmart C4380. Don’t be frighten to buy, even if you’re a tux.
