Search and remove duplicate files

Posted by cviorel on October 14, 2009 No comments | This post has 603 views.

Here a small piece of code which will search for the duplicates in the path you supply. It will generate a new file which contains the commands for deleting those duplicates.
Make sure you double check the resulting file!
The script requires that you have fdupes installed.
Install it in Ubuntu/Debian by running the following command in your terminal:

sudo aptitude install fdupes

1	sudo aptitude install fdupes

#!/bin/bash

OUTF='rm-dups.sh'
echo "#!/bin/bash" > $OUTF
fdupes -r -f $1 | sed -r 's#(.+)#rm '\"'\1'\"'#' >> $OUTF
chmod +x $OUTF

#!/bin/bash

OUTF='rm-dups.sh'

echo "#!/bin/bash" > $OUTF

fdupes -r -f $1 | sed -r 's#(.+)#rm '\"'\1'\"'#' >> $OUTF

chmod +x $OUTF

Karmic Koala Beta on ThinkPad T61

Posted by cviorel on October 6, 2009 No comments | This post has 539 views.

I just installed Ubuntu 9.10 Beta on my LENOVO ThinkPad T61 64608NG.
Here is what I found so far, in two days of intensive usage:

Quadro NVS 140M – 2D and 3D acceleration: tested and works.
Wireless switch: tested and works.
Sound: tested and works.
Enabling touchpad on/off key (fn-f8): not working.
Enabling Active Protection System: works by installing tp_smapi.
Read the complete guide here.
Fingerprint Reader: install thinkfinger-tools and libpam-thinkfinger from the repository and everything works.
Network Card Intel 10/100/1000: tested and works.
Wireless Intel PRO/4965AG: tested and works.
Card reader: not tested.

UPDATE: Power level of the fingerprint reader is set to on by default, so it gets hot pretty fast. Use one of the scripts here to set it to auto at boot time.
Note that the path /sys/class/usb_*/*/device is no longer working. Instead, use /sys/class/usbmon/usbmon*/device/usb*/*.
Here is the complete script for that, taken from thinkwiki.org and modified to reflect the new path.

#!/bin/bash

# find the fingerprint reader and change its power level to autosuspend
find_manuf=STMicroelectronics
find_prod="Biometric Coprocessor"

for devdir in /sys/class/usbmon/usbmon*/device/usb*/*; do
  [[ -r $devdir/manufacturer ]] || continue
  manuf=$(<$devdir/manufacturer)
  [[ $manuf = $find_manuf ]] || continue;
  prod=$(<$devdir/product)
  [[ $prod = $find_prod ]] || continue;
  # if we get here then we have the right device!
  plevel_file=$devdir/power/level
  old_level=$(<$plevel_file);
  # if it is already set properly then exit silently:
  [[ $old_level = auto ]] && exit 0
  # if we successfully change it then exit silently:
  echo auto >$plevel_file && exit 0
  echo "Failed to set the fingerprint reader's power level to 'auto'."
  exit 1
done

# if we make it through the for loop without exiting, the search failed
echo "Could not find the $find_manuf $find_prod (fingerprint reader)"
exit 1

#!/bin/bash

# find the fingerprint reader and change its power level to autosuspend

find_manuf=STMicroelectronics

find_prod="Biometric Coprocessor"

for devdir in /sys/class/usbmon/usbmon*/device/usb*/*; do

[[ -r $devdir/manufacturer ]] || continue

manuf=$(<$devdir/manufacturer)

[[ $manuf = $find_manuf ]] || continue;

prod=$(<$devdir/product)

[[ $prod = $find_prod ]] || continue;

# if we get here then we have the right device!

plevel_file=$devdir/power/level

old_level=$(<$plevel_file);

# if it is already set properly then exit silently:

[[ $old_level = auto ]] && exit 0

# if we successfully change it then exit silently:

echo auto >$plevel_file && exit 0

echo "Failed to set the fingerprint reader's power level to 'auto'."

exit 1

done

# if we make it through the for loop without exiting, the search failed

echo "Could not find the $find_manuf $find_prod (fingerprint reader)"

exit 1

How to fix menu icons in GNOME 2.28

Posted by cviorel on October 5, 2009 No comments | This post has 525 views.

In the latest release of GNOME, they decided to turn off icons in menus by default. This is ugly and if you ask me, not practical at all.
However, you can get those icons back by going to System → Preferences → Appearance, and under the Interface tab, you can check the box “Show icons in menus”. The new GNOME also removes stock icons from buttons. The the above option does not put them back.
To enable icons in menus and butttons, run in your terminal:

gconftool-2 --set /desktop/gnome/interface/buttons_have_icons --type bool true
gconftool-2 --set /desktop/gnome/interface/menus_have_icons --type bool true

1 2	gconftool-2 --set /desktop/gnome/interface/buttons_have_icons --type bool true gconftool-2 --set /desktop/gnome/interface/menus_have_icons --type bool true

Fix Google Earth 5.0 user interface font on Linux

Posted by cviorel on September 2, 2009 3 comments | This post has 861 views.

I installed Google Earth 5.0 and the ugly UI font from the beta is still here.
Based on the comments from Google Earth Help page from here I’ve created the following script wich will fix the user interface font issue.

#!/bin/bash

sudo aptitude -y install libqt4-webkit

HOWTO Force fsck on the Next Reboot

Posted by cviorel on August 19, 2009 No comments | This post has 586 views.

fsck is used to check and optionally repair one or more Linux file systems.
By creating /forcefsck file you will force the Linux system (or rc scripts) to perform a full file system check.
Create a file called forcefsck:

sudo touch /forcefsck

1	sudo touch /forcefsck

Thinkpad HDAPS in Ubuntu 9.04 Jaunty

Posted by cviorel on July 29, 2009 No comments | This post has 865 views.

One of the cool features in a Thinkpad is IBM Active Protection System.
The system consist of two parts. The driver that enables reading the acceleration data and some sort of userspace software that does the actual parking of the harddrive heads, usually hdapsd.
The hdaps driver is part of the kernel but the driver maintainers actually recommend using the tp-smapi driver instead. So that’s what we’ll do.
Make sure you have the necessary tools installed:

sudo aptitude install build-essential module-assistant

1	sudo aptitude install build-essential module-assistant

The tp-smapi is in the package repository (universe):

sudo m-a a-i tp-smapi

1	sudo m-a a-i tp-smapi

This will fetch and install the tp-smapi-source package, unpack the source and then compile and install the kernel module.

Try loading it:

sudo modprobe tp_smapi
sudo modprobe hdaps

1 2	sudo modprobe tp_smapi sudo modprobe hdaps

The kernel log should show something like this:

[ 4504.896887] tp_smapi 0.40 loading...
[ 4504.897178] tp_smapi successfully loaded (smapi_port=0xb2).
[ 4532.702289] hdaps: initial mode latch is 0x05
[ 4532.702442] hdaps: setting ec_rate=250, filter_order=2
[ 4532.702674] hdaps: device successfully initialized.
[ 4532.702788] input: ThinkPad HDAPS joystick emulation as /devices/virtual/input/input22
[ 4532.728212] input: ThinkPad HDAPS accelerometer data as /devices/virtual/input/input23
[ 4532.756552] hdaps: driver successfully loaded.

[ 4504.896887] tp_smapi 0.40 loading...

[ 4504.897178] tp_smapi successfully loaded (smapi_port=0xb2).

[ 4532.702289] hdaps: initial mode latch is 0x05

[ 4532.702442] hdaps: setting ec_rate=250, filter_order=2

[ 4532.702674] hdaps: device successfully initialized.

[ 4532.702788] input: ThinkPad HDAPS joystick emulation as /devices/virtual/input/input22

[ 4532.728212] input: ThinkPad HDAPS accelerometer data as /devices/virtual/input/input23

[ 4532.756552] hdaps: driver successfully loaded.

For some reason some configuration for udev is missing. Fix this by running:

echo 'KERNEL=="event[0-9]*", ATTRS{phys}=="hdaps/input1",ATTRS{modalias}=="input:b0019v1014p5054e4801-*",SYMLINK+="input/hdaps/accelerometer-event"' | sudo tee /etc/udev/rules.d/51-hdaps.rules

1	echo 'KERNEL=="event[0-9]", ATTRS{phys}=="hdaps/input1",ATTRS{modalias}=="input:b0019v1014p5054e4801-",SYMLINK+="input/hdaps/accelerometer-event"' \| sudo tee /etc/udev/rules.d/51-hdaps.rules

Now for the userspace stuff. First let us test if APS is actually working.

sudo aptitude install hdaps-utils

1	sudo aptitude install hdaps-utils

This will install hdaps-pivot or hdaps-gl which you can use to verify that the sensors are working.
You can also test this by running this in your terminal (stop it with pressing CTRL + C):

sudo hdapsd -d sda -s 15 -a -v -y

1	sudo hdapsd -d sda -s 15 -a -v -y

Next we need to update the hdapsd. The one provided in Jaunty is old. There is a PPA with newer versions.

cat | sudo tee /etc/apt/sources.list.d/hdapsd.list << EOF
deb http://ppa.launchpad.net/jonasped/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/jonasped/ppa/ubuntu jaunty main
EOF

cat | sudo tee /etc/apt/sources.list.d/hdapsd.list << EOF

deb http://ppa.launchpad.net/jonasped/ppa/ubuntu jaunty main

deb-src http://ppa.launchpad.net/jonasped/ppa/ubuntu jaunty main

EOF

Add the PPA key:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 45EA2DEACE74152B61554DE4036A90F2BEFC6EB4

1	sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 45EA2DEACE74152B61554DE4036A90F2BEFC6EB4

Update the package list and install the package:

sudo aptitude update
sudo aptitude install hdapsd

1 2	sudo aptitude update sudo aptitude install hdapsd

Install gnome-hdaps-applet (optional).
There is a PPA for this. You can add it like this:

cat | sudo tee /etc/apt/sources.list.d/gnome-hdaps-applet.list << EOF
deb http://ppa.launchpad.net/whoopie79/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/whoopie79/ppa/ubuntu jaunty main
EOF

cat | sudo tee /etc/apt/sources.list.d/gnome-hdaps-applet.list << EOF

deb http://ppa.launchpad.net/whoopie79/ppa/ubuntu jaunty main

deb-src http://ppa.launchpad.net/whoopie79/ppa/ubuntu jaunty main

EOF

Add the key:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com e1c344a23bb057ff1d4d80cf8c236986e1ecdbb2

1	sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com e1c344a23bb057ff1d4d80cf8c236986e1ecdbb2

Update the package list again and install the packages:

sudo aptitude update
sudo aptitude install gnome-hdaps-applet

1 2	sudo aptitude update sudo aptitude install gnome-hdaps-applet

Enjoy!

Random crash of the X server in Jaunty

Posted by cviorel on May 21, 2009 No comments | This post has 559 views.

I experienced a lot of random X server crashes using the proprietary driver for the NVIDIA graphic card on my Thinkpad T61 running Ubuntu 9.04 x86 with Compiz activated.
I managed to fix the problem by installing the lastest NVIDIA driver. I wrote a little script to automate the process and save time. I recommend you to run this in command line mode. Here it is:

#!/bin/bash

# Check if the X server is running
pid_of_X=`ps aux | grep X | grep -v 'grep' | grep root | awk '{ print $2 }'`

if [ -z "$pid_of_X" ];
  then

    echo -e 'X is not running! - Good!\n'
	# Stop the xserver (GDM)

Custom usplash resolution in Ubuntu

Posted by cviorel on May 11, 2009 No comments | This post has 515 views.

Recently I made a clean install of Ubuntu 9.04 on my Thinkpad T61.
I configured the figerprint, the accelerometer is reporting correct values.
I did not like the default resolution at boot. So I created a custom usplash.conf file:

sudo joe /etc/usplash.conf

1	sudo joe /etc/usplash.conf

I should contain these lines:

xres=1680
yres=1050

1 2	xres=1680 yres=1050

The next step was to update the “initial RAM disk”, that is used when the system boots up:

sudo update-initramfs -u

1	sudo update-initramfs -u

Next, I modified my /boot/grub/menu.lst file.
I added as a parameter for the current kernel the value vga=872:

kernel		/boot/vmlinuz-2.6.28-11-generic root=UUID=7281a5b5-6dd5-4011-beff-27339b4b9693 ro splash vga=872

1	kernel /boot/vmlinuz-2.6.28-11-generic root=UUID=7281a5b5-6dd5-4011-beff-27339b4b9693 ro splash vga=872

Nice and clean!
