sudo apt-get install mdbtools-gmdb

1. Extract the source of the application in a folder.
2. Run : ./configure
3. Run : make
4. Now run : sudo checkinstall

checkinstall will ask for some information most of which you can skip except the version of the package being created.

Once finished a .deb file would be created which can be used to install the package by simple double clicking. Packages installed from deb files will get listed in Synaptic Package Manager and can also be uninstalled very easily.

Fix :

1. Get the modeline for the required resolution + refresh rate using the gtf command.

desktop:~$ gtf 1440 900 75

<span id="more-62"></span>

  # 1440x900 @ 75.00 Hz (GTF) hsync: 70.50 kHz; pclk: 136.49 MHz
  Modeline &quot;1440x900_75.00&quot;  136.49  1440 1536 1688 1936  900 901 904940  -HSync +Vsync

The modeline is to be added to the xorg.conf file at /etc/X11/xorg.conf
Take a backup of the file before editing it.

On a fresh Ubuntu installation the file may look small like this :

#Some comments on top
Section "Monitor"
 Identifier "Configured Monitor"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor  "Configured Monitor"
 Device  "Configured Video Device"
EndSection

Section "Device"
 Identifier "Configured Video Device"
EndSection

Section "ServerFlags"
 Option "DontZap" "True"
EndSection

Simply add the modeline to the monitor section like this :

Section "Monitor"
 Identifier "Configured Monitor"
 Modeline "1440x900_75.00"  136.49  1440 1536 1688 1936  900 901 904 940  -HSync +Vsync
 Option          "PreferredMode" "1440x900_75.00"
EndSection

Section "Screen"
 Identifier "Default Screen"
 Monitor  "Configured Monitor"
 Device  "Configured Video Device"
EndSection

Section "Device"
 Identifier "Configured Video Device"
EndSection

Section "ServerFlags"
 Option "DontZap" "True"
EndSection

The option “PreferredMode” “1440×900_75.00″ is used so that it becomes the default resolution on gnome, KDE desktops and GDM and KDM i.e. the login screen. If this option is not used then there may be issues such that resolution after reboot or relogin reverts to a default like 1280 x 1200 as discussed here Bug.

Another fix could to be reconfigure X like : sudo dpkg-reconfigure xserver-xorg.

So using gftp or filezilla or fireftp in this case is a better option.

Switching the speed to 10 and turning off autonegotiation was found to be the solution like this :

sudo ethtool -s eth0 duplex full speed 10 autoneg off

Apart from this the internet connection may be slow due to many reasons like hardware problem , same IP given to 2 machines , IPv6 issues etc.

The above line may be added to /etc/rc.local so that it gets executed every time the system starts.

#!/bin/sh -e
#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.

ethtool -s eth0 duplex full speed 10 autoneg off

exit 0

sudo apt-get install postgresql
sudo apt-get install phppgadmin
sudo apt-get install pgadmin3

After installation the postgres password of postgresql can be changed like this :

ALTER USER postgres WITH ENCRYPTED PASSWORD ‘<***password***>‘;

To exit :
\q

Also create a database :
sudo -u postgres createdb mydb

Now to access localhost/phppgadmin a link needs to be created which points to /usr/share/phppgadmin :

?ln -s /usr/share/phppgadmin /var/www/phppgadmin

Now localhost/phppgadmin should open up

Trying to login with user : postgres and password : created above might give the error :
Login disallowed for security reasons.

To fix this edit /usr/share/phppgadmin/conf/config.inc.php
and change :
$conf['extra_login_security'] = true;
to
$conf['extra_login_security'] = false;

and then login again from phppgadmin and it should work fine.

Alternatively pgadmin3 can also be used to work with postgresql.
Start pgadmin and create a new connection using the icon on top left and it should work fine.

The menu can be added as an applet to the panel in Ubuntu gnome desktop also by installing the package :

gnome-main-menu

sudo apt-get install gnome-main-menu

After installation right click on a panel and Add to Panel. Add ‘The main gnome menu’ from the list which shall be a start menu like the one on openSuse

1. Control Center > KDE Components > File Manager > Previews & Meta-Data for the Maximum File Size in the slider. If it is too low then increase it to say 5 MB.

2. Open Konqueror. In the menu View > Preview check whether previews are enabled or not. If disabled then enable them. Various file types can be selectively enabled or disabled for preview.

1. tomcat5.5
2. tomcat5.5-webapps
3. sun-java6-jdk

They can be installed from command line using the command sudo apt-get

After synaptic finishes installing them open /etc/default/tomcat5.5 and edit it as follows :

Find :
#JAVA_HOME=/usr/lib/jvm/java-6-sun

Change : Remove the # so that it is uncommented.
JAVA_HOME=/usr/lib/jvm/java-6-sun

It points to the java home which can be java-6-sun or any other java .

Then restart tomcat5.5 from command line like this :

enlightened@enlightened-desktop:~$ sudo /etc/init.d/tomcat5.5 restart
* Stopping Tomcat servlet engine tomcat5.5 [ OK ]
* Starting Tomcat servlet engine tomcat5.5 [ OK ]

Now open in your browser the url :

http://localhost:8180/

And the welcome page of Apache Tomcat should appear.

The file
/usr/share/tomcat5.5/conf/tomcat-users.xml
has the default username and password listed which is username : tomcat and password : tomcat.

On the tomcat welcome page Tomcat Administration link is on the left :
http://localhost:8180/admin

Opening this page might show the error message :
HTTP Status 403 – Access to the requested resource has been denied

To fix the above issue open the file
/usr/share/tomcat5.5/conf/tomcat-users.xml

sudo gedit /usr/share/tomcat5.5/conf/tomcat-users.xml

and add a role called admin and user called admin with that role :

<role rolename=”admin”/>
<user username=”admin” password=”tomcat” roles=”tomcat,admin”/>

Restart tomcat from command line as shown above.

Now log in to the administration panel :
http://localhost:8180/admin

with username : admin and password : tomcat.
The login should take you to the admin panel without any error.

To the left is another link of Tomcat Manager :
http://localhost:8180/manager/html

which might still show the error of Access denied.

To fix this issue simply login to the admin panel and create a role called manager (if it doesnt exist) and assign this role to a non-admin user like tomcat or create a new user.

Then log in to the Tomcat Manager page and it should open fine without any errors.

Now /usr/share/tomcat-webapps is the folder that contains the jsp files/webapps which are accessible from localhost:8180 url.

To change the directory of webapps to say one in /home/username/tomcat

Open : /usr/share/tomcat5.5-webapps/ROOT.xml

Look for :
Context path=”/” docBase=”/usr/share/tomcat5.5-webapps/ROOT”
and change the docBase value to the folder where the tomcat webapps would be.
e.g.

Context path=”/” docBase=”/home/enlightened/tomcat”
or
Context path=”/” docBase=”/var/www/tomcat”

Save the file and restart tomcat.

One more thing you can do is copy the contents of the /usr/share/tomcat5.5-webapps/ROOT directory to this new directory and then open the url localhost:8180 to check that everything is working fine. The admin and manager pages on the left and the jsp examples also should all open fine as previously.
