Unclutter is a small but unique package for X11. What it does is very simple: if you aren’t using the mouse, it hides the mouse…
After the ugly-cheap-o-dongle-microtune I bought on Ebay for 20€ inc P&P a PCMCIA 3Com bluetooth card:
The main advantage is the retractable antenna and the PCMCIA small size doesn’t protrude from the laptop ( very interesting, compared to the usb stick)
I assume you already install all the previous software needed in the previous topic.
You should install all this packages:
sudo apt-get install gnome-bluetooth obexserver bluez-utils bluez-passkey-gnome
And add bt-applet in start up session, to allow pairing.
Start the blutooth service.
sudo sh /etc/init.d/bluetooth start
Insert the PC card, and type:
tail /var/log/syslog
You will probably get that:
pccard: PCMCIA card inserted into slot 0
pcmcia: registering new device pcmcia0.0
bt3c_open: Firmware request failed
You need to download the 3Com firmware as detailed to the bluez website:
3com pcmcia driver
The driver for the 3Com and HP Bluetooth PCMCIA card is called bt3c_cs and to make this device working a firmware download is needed. Due the licence issue the firmware is not distributed with any of the BlueZ packages. The firmware file can be found at the Windows driver distribution or on the driver CD-ROM. The following command will extract the BT3CPCC.bin file into the right place on the local file system:
sudo sh
unzip -p btp1_1en.exe \
Drivers.W2k/BT3CPCC.bin > /lib/firmware/BT3CPCC.binThe 3Com Bluetooth card 3.0 (3CRWB6096B) will not work with this driver. This card is a simple serial port based Bluetooth PCMCIA card and must be used together with the hci_uart driver.
And it works straight , that means, you can scann the service available.

Then you can install Phone Manager to send SMS from your PC.
Or also Wammu is a very good phone manager, compatible with nokia to manage sms, contact , sms, todos and also calendar.
Select in device settings, the mac address and bluephonet as connection.
Here appear a problem, the need of pairing the device, when you try either from the phone or from the computer, it fails after asked you for the PIN.
To solve it, edit the file to enable and set a new pin:
sudo gedit /etc/bluetooth/hcid.conf
And in the file, be sure to have:
# Automatically initialize new devices
autoinit yes;
# Pairing mode
pairing multi;# Default PIN code for incoming connections
passkey “1234”; # or the pin you wish

Still running with a Toshiba Satellite M60-103 embbeding a ENE CB-712/4 card reader who doesn’t work with Ubuntu
To check the model of your reader:
lspci -v | grep ENE

And If you get this error while hibernating:
[17233006.828000] mmc0: Got command interrupt even though no command operation was in progress.
[17233006.828000] mmc0: Please report this to.
[17233006.828000] mmc0: Card is consuming too much power!
[17233006.828000] mmc0: Unexpected interrupt 0x00800000. Please report this to.
So needed to disable the mmc_core: sdhci module
sudo rmmod sdhci
sudo sh -c ‘echo blacklist sdhci >> /etc/modprobe.d/blacklist’
I’m running with a laptop and Ubuntu 6.10, and during the night a very small access to the HD every 3-5 sec is annoying, plus can maybe shorten the hdd life time.
This is a bug is oppened:
https://launchpad.net/ubuntu/+source/dbus/+bug/17878
You can check if your are involved, type:
sudo hdparm -y /dev/hda
or (for sata)
sudo hdparm -y /dev/sda
to stop then hard drive wich should spin down and up just after a while.
A temporary solution is to enable the laptop_mode, but the hdd stop after 5sec, a bit annoying.
sudo laptop_mode start
and then edit this file:
/etc/laptop-mode/laptop-mode.conf
To makes it start on boot and set the halt drive time at 10 min
