Patching and compiling OpenOffice.org on Ubuntu Gutsy

If you noticed, I seems to disappear for 2 weeks because of freezing bug in OpenOffice.org. I spent 2 weeks for only one task; compiling OpenOffice.org on Ubuntu Gutsy.

Unfortunately, all Gnome dialog seemed to be broken. They were so long about 10 times of my screen.

My friend asked me to verify suspension of web hosting services which the domain name server has been changed to other hosting service. He just has a long file with a domain per line.

How to change keyboard layout in Ubuntu Server

I'm testing web hosting control panel inside virtual machine. The operating system I chose is Linux and the distribution is Ubuntu Gutsy Gibbon.

That's why I would like to change it right now.
