Wortmann Terra Mobile 1450 II running Ubuntu!

Today I got my new ultrabook 'Wortmann Terra Mobile 1450 II' with Intel i7-3517U, 8GB and 240GB SSD. This is a great ultrabook! 

I installed Ubuntu 12.10 64bit. Works great out of the box. Only one issue concerning the missing TouchPad functionality. As explained in this forum this problem can be easily fixed with the following changes of linux kernel options. (Please note that you should have already worked with Linux before you change your configuration - If it goes wrong you can make a refresh install ;-).

  1. make a copy of the grub boot loader configuration '/etc/default/grub'
  2. edit the configuration file '/etc/default/grub'
    for example from a terminal with the command:
    >sudo vim /etc/default/grub
  3. change line GRUB_CMDLINE_LINUX="" into GRUB_CMDLINE_LINUX="i8042.noloop"
  4. save your changes
  5. from a terminal run the command: 
    >sudo update-grub 
  6. finally reboot your system

Now the touchpad should work. You can enable/disable it also with key 'Fn+Esc'

Optimize the SSD

In addition I changed the settings of my SSD in the '/etc/fstab'. If you edit this file you can add the options 'noatime,nodiratime'. For example the mountpoint can look like this:

UUID=[ID] /               ext4    errors=remount-ro,noatime,nodiratime 0       1

Note that '[ID]' means here your! partition-id - don't change it!

 

Update 19.12.2012

After I had some randomly system freezes, I installed manually the kernel version 3.6.10.
With this kernel the system runs now stable. I think the kernel update is mandatory.

postfix and no worthy mechs found

Today I configured postfix on my unbutu machine to test some improvements sending out mails to a smtp mail server.

I followed this introductions: 

http://wiki.ubuntuusers.de/Postfix

My smtp server / relayhost needs an authentification. So I configured my main.cf with the following smtp params:

smtp_sasl_auth_enable = yes
# noplaintext weglassen, wenn Passwörter im Klartext übertragen werden müssen:
# (nicht empfohlen, nur wenn's anders nicht funktioniert)
smtp_sasl_security_options = noplaintext noanonymous
smtp_sasl_password_maps = hash:/etc/postfix/sasl_password

But now I received the following error message on my mail.log 

Feb 28 00:25:44 xxx postfix/smtp[8756]: warning: SASL authentication failure: No worthy mechs found
Feb 28 00:25:44 xxx postfix/smtp[8756]: 2794717E510: to=<xxa@xx.com>, relay=www.xxx.com[xxxxxxx]:25, delay=21, delays=0.05/0.01/21/0, dsn=4.7.0, status=deferred (SASL authentication failed; cannot authenticate to server xxx[xxx]: no mechanism available)

To solve this problem I found this thread:

http://www.zimbra.com/forums/installation/1240-cannot-sasl-authenticate-server.html

So the solution for me was to set the following two smtp params to an empty string:

smtp_sasl_security_options =
smtp_sasl_mechanism_filter =
smtp_use_tls = no

Now postfix works fine and is able to send out mails to my relayhost.

Ubuntu - MySQL - Glassfish

To install MySQL on Ubuntu to be used in a Glassfish JEE App is very easy. 

You can download and install MySQL Server using the Synaptic Tool in Ubuntu. During Setup you will be asked for a root password. this is a password for the user "root" inside the mySQL Server. So its not your Linux root password.

After intalling mysql server you can easily start and stop it with

 > sudo /etc/init.d/mysql start

 > sudo /etc/init.d/mysql stop

To get into the mysql console use

 >mysql -u root -p

There you will be ask for the mysql root password.

To create a new database use the following command form the mysql console:

mysql> create database my_database;

Now you can setup the JDBC Pool inside Glassfish server.

First download the JDBC Driver form mysql download page and put the 'mysql-connecto-java-5.1.x.jar' into glassfish/domains/domain1/lib/ext

use the following Class Name to configure you JDBC Pool:  com.mysql.jdbc.jdbc2.optional.MysqlDataSource

Use the additional params:

  • databaseName : [you_database_name]
  • user: root
  • password : [you mysql admin password]
