Firefox causes massive Xorg CPU usage

Friday, May 18th, 2007

OS: Xubuntu 7.04 (Feisty)
Firefox Version: 2.0.0.3
Xorg Version: 1: 7.2-0ubuntu11
Problem: Sometimes, Firefox is running very slowing, though it is not always slow. Running “top” tell me that Firefox plus Xorg takes up of 90% CPU usage.
Solution: 1. add this line to the “Device” section of my /etc/X11/xorg.conf:

Option “AccelMethod” “exa”

2. add MOZ_DISABLE_PANGO=1 to /etc/environment

It looks like an often problem to many people. A few articles give more details:

Saturday, May 12th, 2007

Nvu isn’t available in the official Ubuntu repositories, but fortunately backports.org has an Nvu package for Debian Etch which works on Ubuntu Feisty Fawn, too. It can be found on http://backports.org/debian/pool/main/n/nvu/. Go to that address with your browser and download the latest Nvu package, e.g. nvu_1.0final-0bpo1_i386.deb.

In the Firefox download window, select Open with GDebi Package Installer (default).

A Package Installer window comes up. Click on the Install Package button to install Nvu.

You must provide your password to start the installation.

The installation begins.

Afterwards, you can close the Package Installer window.

Nvu is now installed already.

Wednesday, May 9th, 2007
Bibus is a bibliographic and reference management software. As with other such tools, Bibus allows one to search, edit, and sort bibliographic records. In addition, Bibus contains features that makes it unique among open source and even commercial bibliographic databases:

* Hierarchical organization of the references with user defined keys
* Designed for multiuser environments
o You can share the database between an “unlimited” number of users
o Each user will have its own classification
o You can define read-only and read-write users
* Live queries; that is searches that update as the database changes
* On-line PubMed queries
* On-line eTBLAST queries
* Insertion of references and formatting of bibliographies into two widely used Word Processors (OpenOffice.org and Microsoft Word)
* Foreign language support through Unicode and gettext. As of version 1.2, Bibus is available in English, French, Portuguese, German, Spanish and Chinese.
* Bibus works on most modern platforms:
o Gnu/linux with OpenOffice.org
o Windows98/2000/XP with OpenOffice.org and Microsoft Word
o On other platforms (MacOS X, …) Bibus works with Microsoft Word but styles cannot be created at this point (this should change soon for MacOS X)

Add the following two apt source into your system

deb http://switch.dl.sourceforge.net/sourceforge/bibus-biblio ./
deb-src http://switch.dl.sourceforge.net/sourceforge/bibus-biblio ./

You can do this by editing the file “/etc/apt/sources.list” or using GUI software provided by Xubuntu default.

then

apt-get update

install the following three packages:
“python-pysqlite2″ “bibus” “bibus-doc-en”
only these three and their dependences are enough. Do not install “openoffice-pyuno”, which is outdated and Openoffice have install a new version by default.

Note: If you want Bibus run smoothly without any further configuration, make sure you install all components of Openoffice including excel, writer, database, drawing and etc.
