Running the desktop/X11 is very resource intensive, you probably don't want to do it all the time or on production server. Follow the instructions here to start your ubuntu in text mode only.

By default, Ubuntu server 10.04 LTS is text mode only. Follow the stesp below to install X11 (or full desktop).

1. sudo apt-get update
2. sudo apt-get install ubuntu-desktop
3. sudo reboot

After restart, the login screen should show up.

Enable Alfresco JavaScript Debugger

Reference http://aboutalfresco.blogspot.com/2009/11/enable-javascript-debugger.html
The debugger will open in a Java swing window. So it won't work if the server doesn't have GUI, for example, ubuntu without X-windows.

2. Open node browser
3. workspace://SpaceStore > children categoryRoot > children taggable

Alfresco Tomcat JVM Tuning

I have an Alfresco installation with Tomcat server. Which file shall I use to setup JAVA_OPTS for tomcat?

The JAVA_OPTS is not set in alfresco.sh or catalina.sh. Instead, it is in tomcat/scripts/ctl.sh. Stop tomcat, make necessary changes and restart tomcat. You can verify it by

sudo ps -ef | grep java

Start CentOS without GUI

I have a VM with CentOS 6.0. It runs quite slow. To speed it up, I decide to turn off X11 GUI. Following the instructions here, this can be done by editing /etc/inittab. Just change from 

id:5:initdefault:

to

id:3:initdefault:

and restart.
