From HowtoForge, here come the guides to makes a perfect desktop using Ubuntu 8.04 LTS

The guides really simple and straight forward, just follow the steps provided and you’ll have a great Desktop.

Finally Ubuntu 8.04 is OUT!!! I’ll download the desktop and server edition and play with both. Especially the server edition because someone ask me how to install and configure Ubuntu for Web, Database and File server.

He is server is using AMD 64bit but I am just download the 32bit as my test bed, and if everything ok! I can do the same thing with Ubuntu 8.04 Server 64bit.

VGA card ATI X200M. Error “composite extension is not available” when I try to activate Desktop Effect.
Found on UbuntuForums.com a thread about it. Using below instruction, now I can activate Desktop Effect.

“In order to get the desktop effects to work I first had to install the ATI driver using the Restricted Drivers Manager.
Then I had to install xserver-xgl using the Synaptic Package Manager located under System–>Administration–>Synaptic Package Manager. Just do a search for xserver-xgl in the Synaptic manager to find it.
While you are there you might want to install the compizconfig-settings-manager as well.
After those are installed reboot and then you should be able to select Extra in the Visual Effects tab under System–>Preferences–>Appearance.”

My LCD screen is 14.1 widescreen but monitor resolution is 1024×800
Everytime I change resolution with Screen Resoluion above 1024×800 (say 1280×800) my screen is garbled
Then I try to re-create again file /etc/X11/xorg.conf using command
$ sudo dpkg-reconfigure xserver-xorg
and answer all question in there by default
note: my VGA card is ATI Radeon Xpress 200M so I choose ati as the driver
after succesfully creating new /etc/X11/xorg.conf I restart my Ubuntu
(as I dont know how to activate new configuration)
Login again, and try Screen Resolution from System > Preferences and choose 1280×800.
Whala…. my screen can switch into 1280×800 without garbled…
Oh I love it, more in love with Ubuntu. Now I can see it in Widescreen monitor

note: after I re-create the /etc/X11/xorg.conf, now I can use the scroll button on my mouse and side-scrool on my touchpad without have to installing Synaptics…. yoo hoooo…

Ok now my screen resolution already 1280×800, but still I need more enhanment, need more love from Ubuntu. I want to enable Desktop Effect. last time I tried with Fedora 6 and 7, it can enable Desktop Effects although already installing ATI-drivers
so I am trying again now with Ubuntu.

Go to http://ati.amd.com/support/drivers/linux/linux-radeon.html
download the driver

$ chmod +x ati-driver-installer-8.42.3-x86.x86_64.run
$ sudo su
# ./ati-driver-installer-8.42.3-x86.x86_64.run

After succesfull installation, restart the notebook.
But it seems it only copy a file, not configuring the xorg.conf
Run ATIConfig
$ sudo aticonfig –initial –input=/etc/X11/xorg.conf

restart notebook again.
My screen still good at 1280×800, now try to enable Desktop Effects.
Waiting…. the screen goes blank………
then it succesfully enabling Desktop Effects, wow!!!! More,… more beatiful…
I begin to think to use Ubuntu for my daily use.
I want my Ubuntu prettier, more softwares, more powerfull….

yooohooo….

Make sure your PC is safe when you leave it and forget to lock it

Dont forget to tickmark “Lock screen when screensaver is active”
