Installing true type fonts in Ubuntu

Even we are using Ubuntu we may sometimes want to or need to use some Microsoft true type fonts. For that we can follow the following steps to install true type fonts in our Ubuntu.

We can install the MS core fonts by installing the msttcorefonts package.
To do this, enable the “Universe” component of the repositories.
Then run the following command in the terminal:

$sudo apt-get install msttcorefonts

This will give us the core fonts, but if there are other TrueType fonts that we want installed, it is as easy as copying the font files to the ~/.fonts/ directory.

After installing new fonts, we will have to log out and log in again to be able to see and use the new fonts. If we want to avoid this, we can regenerate the fonts cache by issuing the following command:

$sudo fc-cache -fv

Using Mobile as USB Modem in Ubuntu

Now I am at Chittagong, enjoying my eid vacation here. Normally I use broadband at my home at Dhaka. But I am so much addicted in Internet that I can’t pass a single day without it and also I can pass all my time without eating or drinking if I get Internet. So, I faced a problem here that is my sister use GP Edge and I have to use this as alternate here. But I use Ubuntu Hardy 8.04 in my laptop and I don’t have any other OS. I never used any phone as modem in Ubuntu. I could have used my sister’s laptop but I didn’t feel comfortable as I will miss all my personal settings in which I am used to. So I started looking for how I can install the mobile set in my laptop. It’s a Nokia 6280 phone. I have searched over internet and finally by taking help from two site I have succeeded using it. The steps I have followed to install it are as follows:

1. Connected the phone using USB cable.
2. Open the terminal.
3. Check the USB detection:-

$ lsusb

Bus 003 Device 003: ID 0421:045a Nokia Mobile Phones
Bus 003 Device 002: ID 04f3:0210 Elan Microelectronics Corporation
Bus 003 Device 001: ID 0000:0000
Bus 004 Device 001: ID 0000:0000
Bus 002 Device 001: ID 0000:0000
Bus 001 Device 001: ID 0000:0000

4. Autodetect the modem using WVDial:-

$ sudo wvdialconf
Found an USB modem on /dev/ttyACM0.
Modem configuration written to /etc/wvdial.conf.
ttyACM0<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"
ttyACM1<Info>: Speed 460800; init "ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

5.

 sudo gedit /etc/wvdial.conf
[Dialer Defaults]
Init1 = ATZ
Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
Init3 = AT+CGDCONT=1,”IP”,”gpinternet”
Modem Type = USB Modem
Baud = 460800
New PPPD = yes
Modem = /dev/ttyACM0
ISDN = 0
Phone = *99***1#
Username = gp
Password = gp

6.

 sudo ifdown eth0 

[it will disable your LAN connection]

7. finally execute

$ wvdial

Now I am connected to GP Internet.

Special thanks to Mr. Hasan for the step 6. Without this I tried again and again but couldn’t get connected.
