What can you do if your Ubuntu display screwed up

When I upgraded my Ubuntu Linux in my laptop from 8.10 (Intrepid) to 9.04 (Jaunty) using the "Upgrade to 9.04" option in Synaptic Package Manager, it didn't go smoothly.

After the packages download, upgrade, cleanup and restart, the login screen can't show up, and it jammed up in a distorted screen. My first tought was that the display driver or setting was not working well with the display hardware of the laptop.

Luckily, I managed to fix the problem within half an hour. And here is my solution:

  • Press the Esc key during Grub bootup to bring up the kernel menu.
  • Select the 2nd option "Ubuntu 9.04, kernel 2.6.28-11-generic (recovery mode)" to go to recovery mode.
  • When the Recovery Menu show up, you can try to select "xfix - Try to auto repair graphic problems". However this didn't work for me.
  • Therefore, I had to try another way and selected "netroot - Drop to root shell prompt with networking". I think you can also select "root - Drop to root shell prompt" as well.
  • Key-in the root password, and you will enter to the root's shell command prompt.
  • Key-in this command to manually configure the Xorg-server settings: "dpkg-reconfigure xserver-xorg".
  • You will need to configure for the input devices (eg. keyboard) as well as the output devices (eg. display and monitor).
  • When you get back to the command prompt, key-in "exit" to end the shell session and go back to Recovery Menu.
  • Now, select "resume - Resume normal boot".
  • If the display problem is fixed, you will see a beautiful reddish login screen with a stylish 3D Ubuntu logo on the bottom right.
  • Welcome to Ubuntu 9.04 (Jaunty Jackalope).

Cloud computing with Ubuntu Server Edition 9.x

One of the excitement from Ubuntu Server Edition 9.04 (Jaunty Jackalope) which just released on 23 April 2009 is new features in cloud computing.

Ubuntu Server Edition 9.04 provides 2 flavours of cloud, namely:

  • Ubuntu on Amazon EC2 which uses the publicly available Amazon's Elastic Computing (EC2) cloud computing service.
  • Ubuntu Enterprise Cloud for enterprises to build their own private cloud environment on their servers, which is powered by the Amazon EC2-like open source Eucalyptus system. Eucalyptus (Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems) is a cloud system with an EC2-compatible API, elastic block storage (EBS) equivalent and an S3 compatible storage manager.
Cloud computing transforms traditional server infrastructure into a dynamic environment that expands and reduces capacity depending on requirements.

A cloud computing environment combines the resources of a group of servers together over a network. This group of servers is the cloud that provides access to resources on demand.



Adopting a cloud-computing strategy helps businesses conduct their core business activities with greater efficiency and flexibility. It enables greater utilisation of existing hardware while also providing the ability to handle peaks in usage. Thousands of virtual machines and applications can be managed more easily using a cloud-like environment.

Canonical has announced that the next version of Ubuntu Linux 9.10 (Karmic Koala) is planned to be very cloud oriented. As such, we can expect more in the cloud to come.

Will Metro Kajang repeat the history of TSH?

Several years ago, I made some big bucks with TSH (陈顺风资源,9059) and its warrant, when they ventured into palm oil business. By that time, it was still well-known as a cocoa products manufacturer then classified in the Industrial sector in KLSE.

TSH's earnings improved significantly when its palm oil business started to bring in revenue, and hence pushed up its stock price as well as its warrant price. Later, it was reclassified under the Plantation sector, and the rest is history.

Now, Metro Kajang (METROK 美景控股, 6114) well-known as a property developer in Klang Valley has also ventured into palm oil business since December 2007 by acquiring 15,942.60 hectares of land in East Kalimantan to plant oil palm. It might take them 3 years until 2011 before the palm oil business begins to contribute to its revenue, and now the time has already gone halfway of the milestone.

East Kalimantan in Indonesia is a strategic location for oil palm plantation as it is expected to have better yield per hectare, lower labour cost, etc. In fact, several public listed plantation companies in KLSE also expanded their plantation business to Indonesia over the past few years.

The 15,942.60 hectares land bank of Metro Kajang is considered small, compared with other public listed plantation companies, such as:

  • ASIATIC (2291) - 80,000 hectares
  • CEPAT (8982) - 10,300 hectares
  • IJMPLNT (2216) - 29,797 hectares
  • IOICORP (1961) - 169,450 hectares
  • KLK (2445) - 210,000 hectares
  • KULIM (2003) - 82,730 hectares
  • TSH (9059) - 20,000 hectares
  • SIME (4197) - 531,300 hectares

however, it is a good size to start with, and probably will be expanded in the future.

It is worth to note that although plantation is considered a new business to Metro Kajang, it is not new to their executive chairman Dato' Chen Kooi Chiew who already has 18 years of experience in that sector.

Unlike TSH (which once troubled by their cocoa business), the core business of Metro Kajang i.e. property development and management remains strong and dynamic. This business has never fail them since commencing over twenty years ago, as they have uninterrupted profit track record from day one. Therefore, the new plantation business is not expected to override their property business like TSH, but would be another good revenue generator beside the property business.

Beside that, Metro Kajang has other kinds of businesses, which contribute not as significant as their property business. That include furniture manufacturing (in China), money lending, lifestock farming and food processing.

In the short term, their lifestock farming and food processing business is seen to be affected by the current swine flu incident. This might cause some effect on their stock price performance, which might provide some good opportunity for continue accumulation. In the long term, we have seen Metro Kajang has been aggressive in buying more land banks for their property development, and the plantation business should start to bring in revenue from next year (2010) onwards. The importance of this new plantation business can be sensed from the cover page of their 2008 Annual Report.

Despite its low share price at RM0.90 only, Metro Kajang has an NAB per share of RM2.73, net cash per share of RM0.20, cash flow per share of RM0.34, and debt/equity ratio at 0.31 only. These mean that they are financially strong. With the prospected EPS of 16 sen for the coming year, the estimated PE ratio stands at 5.62 by today's closing.
