Ubuntu Karmic : Vodafone Dongles

Vodafone Mobile Internet Dongles used to work on previous versions of Ubuntu. Unfortunately Ubuntu Karmic 9.10 has issues and cannot connect to the Internet.


Fix Vodafone Dongle(only need to do this once)

1) Safely Unmount the Virtual CDrom and SSD card
  • Click Places->Computer
    If you see a virtual CD rom & a SSD card slot
    right mouse click on the Virtual CD rom (you don't need it, there windows drivers) & select safety remove device)
    Then when the SSD card reader & virtual CD rom has dissapered , close the computer browser box

2) Open a terminal up
  • Click Applications->Accessory->Terminal
    Then copy & paste these
sudo rmmod usb-storage
sudo modprobe -r option
sudo modprobe -r usbserial
sudo modprobe usbserial vendor=0x12d1 product=0x1001
sudo pppd ttyUSB0

Then every time you plug the Dongle into Machine
Double check that your virtual CD ROM AND SDD card is not mounted.
See step 1 of this resolution

Connected to Internet and No Internet still!?
Vodafone's Connection Service sometimes plays up giving information to your computer that enables you surf the Internet.

So keep just keep trying to connect and check your nameservers assigned by typing
cat /etc/resolv.conf

Ubuntu: Stuttering Sound

Stuttering sound
Sometimes the sound just doesn't and some times it does

Possible Reasons
I have seen odd sound effects sometimes on older hardware. I Believe as of 8.04, the Ubuntu team moved to "PulseAudio" instead of ALSA.

PulseAudio is still in development to support older sound hardware. Yet ALSA still supports the old.

Switching Safely from PulseAudio Back to ALSA (Ubuntu Karmic)
Run the following commands in this order:
$ sudo apt-get purge pulseaudio gstreamer0.10-pulseaudio
$ sudo apt-get autoremove
$ sudo apt-get install alsa-base alsa-tools alsa-tools-gui alsa-utils alsa-oss linux-sound-base alsamixergui
$ sudo apt-get install esound esound-clients esound-common libesd-alsa0 gnome-alsamixer
restart your computer!
Final Thoughts
It does kinda improve the sound quality, yet u may need to tinker with the PCM and Master volume to get the stuttered lowered to almost nothing.

ThinkPad and Linux

I've an old 'IBM ThinkPad T20 2647' and still wondering about how to improve my sound issues. I stumbled upon this place.

Anything related to ThinkPad issues and Linux is here.

Yet I still have yet to find an issue with my sound volume. I am starting to find clues...

My Sound Issues
  • Everytime I raise or lower the volume, the sound output corrupts
  • If I start another application with sound, it corrupts the output (Obviously it cannot handle more than one application playing sounds, probably driver)
FIXED!!!! see my new posting coming

Xubuntu 9.10 : Fix Muted Sound on Startup

Thanks to Ubuntu community they did it again for me ^^.

sudo mousepad /etc/init.d/alsa-utils

near the end of the file, comment out the line (Place a # character at the beginning of the line)

mute_and_zero_levels "$TARGET_CARD" || EXITSTATUS=1

Moments Later...
Due to my budget IBM ThinkPad with dodgy sound issues, think I'll keep it muted heh. [/me uncomments line again]
