Yesterday I got my new shiny Acer aspire one 722 netbook, it comes with windows 7 starter and I’m not going to stick with it for long but before I start with my experiments I thought of creating a recovery image for it. Having one is particularly useful if things go wrong and you want to use Acer’s warranty, trust me it’s a pain in the rear to explain to the customer support that you use linux or another operating system. Fortunately acer ships with Acer E Recovery Management which is an excellent utility to create a startup disk. I used my USB drive to create a restore disk and also to store my drivers. The only problem is that it took a total of about 12GB out of the 16GB available on my USB drive. I keep using the pendrive for other things too so this couldn’t be a permanent solution.

After installing the 12.04 LTS version of ubuntu I was quite happy with the performance of the system, there was however one thing that bugs me. It’s unity of course, if you like unity then don’t bother reading further but if you don’t like it then Cinnamon is for you.
I switched to ubuntu after the new LTS release and was having some problems with my MTS Mblaze connection. Sometime’s it’d work and sometimes it wouldn’t. There seems to be a bug in modem-manager which constantly keeps crashing so I decided to use wvdial instead. We need to install the wvdial package
sudo apt-get install wvdial
and then create the file /etc/wvdial.conf
[Dialer mts] Stupid Mode = 1 Inherits = Modem0 Password = mts Username = email@example.com Phone = #777 [Modem0] Init1 = ATZ SetVolume = 0 Modem = /dev/ttyUSB0 Baud = 115200 FlowControl = Hardware (CRTSCTS) Dial Command = ATDT
Then we can connect to the internet using
sudo wvdial mts
This is the output that I get when the dialer is run. Occasionally it will have some problems you can just disconnect and try again.
