HOWTO : Google Public DNS

Google Public DNS is a free, global Domain Name System (DNS) resolution service, that you can use as an alternative to your current DNS provider. It is faster and more secure than OpenDNS.

Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your primary and secondary DNS servers respectively.

HOWTO : Screen resolution on Ubuntu 9.10

When your display cannot report the correct EDID (Extended Display Identification Data), your X will not work properly. Usually, it will display 800x600 resolution or lower although your display is 1024x768 or higher.

Step 0 :
sudo service gdm stop
sudo Xorg -configure
sudo service gdm start

Step 1 :
If your monitor is 1024x768 at 60Hz, you can go to the following site and calculate the modeline.

Calculator for video timings

Select standard "1024x768@60Hz" mode and press the Calculate button.

The modeline will be as the followings :

Modeline "1024x768" 65 1024 1048 1184 1344 768 771 777 806 -hsync -vsync

Copy and paste the captioned "modeline" to "Monitor Section" of ~/xorg.conf.new.

Step 2 :
sudo cp xorg.conf.new /etc/X11/xorg.conf

Step 3 :
Go to "System" - "preference" - "Display"

Choose "Yes" and select the desired resolution then save.

Step 4 :
Reboot your system or restart X.

If you are using nVidia display card, you need to do the following.

Step a :
Install the nVidia driver from "System" - "Administration" - "Hardware driver".

Reboot your system.

Step b :
sudo nvidia-xconfig

Step c :
gksudo nvidia-settings

Select the desired resolution and save to the configuration file.

Step d :
Go to "System" - "preference" - "Display"

Choose "No" and select the desired resolution then save.

Step e :
Reboot your system or logout and login again.

That's all. See you!

HOWTO : HSDPA/HSPA modem on Ubuntu 9.10

When you are the first time using HSDPA/HSPA modem on Ubuntu 9.10, you will not encounter any problem. However, when you use the modem the second time, it hardly to get the DNS. As a result, you cannot surf the internet.

Therefore, you should write the DNS down when you insert the HSDPA/HSPA modem to the Ubuntu 9.10 the first time. Add the DNS to the Network Manager by editing "IPV4 Setting" - "PPP address only".

The following are some service providers in Hong Kong :

HOWTO : Ubuntu 9.10 on Gigabyte TouchNote T1028X

HOWTO : Ubuntu 9.10 on Gigabyte TouchNote T1028X

Hardware configuration

Intel Atom N280 1.6GHz CPU
2GB DDR2 677HMz RAM
250GB 2.5" Hard Drive (Changed to Intel X25-M 80GB SSD)
10.1" Touch screen
PC Express card slot
3 x USB 2.0
All-in-one card reader
Carrying bag

This tablet netbook is in good desgin and quality. It is purchased on 2009-DEC-11 at $4,700-HK with USB mouse and screen protector as gifts. However, the screen protector is a little bit larger than the screen. I also added a Hauwei EM770 3.75G HSDPA modem and changed the hard drive to Intel X25-M 80GB SSD. The total cost is increased to $7,260-HK. Although the price is more or less reached the mid-range notebook level, it is worth to buy. By the way, it is a little bit heavy when holding it with one hand using touch screen feature.

Make sure to update your BIOS to "FC" version as it will activate the Wifi by default. The machine comes with "FB" version of BIOS.

The machine almost works perfectly on Ubuntu 9.10 including HSDPA modem but except touch screen feature. We need to do something to make it work.

Installation of Ubuntu 9.10

Make sure to press F6 on the startup menu and choose "expert mode" and followed by "Esc". Otherwise, your mouse will not work after the boot up.

Append the following line at the end of the command displayed on the screen.

elevator=noop i8042.noloop=1

Install Ubuntu 9.10 as usual. After the first boot up your mouse cannot work. Just follow the steps below to make it work again.

Press Ctrl+Alt+F2. At the command prompt, enter your username and password.

sudo nano /boot/grub/grub.cfg

Locate "linux" tag and append the following at the end of the line.

elevator=noop i8042.noloop=1

Save and reboot your system.

** Note : you need to add the line on every kernel updated.

Configure touch screen

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

sudo apt-get install xserver-xorg-input-evtouch gnome-randr-applet

That's all. See you!

HOWTO : Why partitioning does matter on Ubuntu?

Ubuntu is one of the most user-friendly Linux distributions in the world. However, Linux distributions change a lot on every new release. Although we can upgrade to the newer release easily on Ubuntu, I suggest to have a fresh install on every new release.

In my opinion, it is a good practice to format your hard drive at least in four partitions. Such as

/boot (about 1GB)
/ (not less than 8GB)
/home (depends on your hard drive space reminded)
/swap (twice as your amount of RAM)

In this way, you can install and format /boot and / partitions and leave /home untouch on every new or re-install. All your settings at /home are reminded unchange as well as the data in that partition. Be keep in mind that you are NOT required to format /home partition.

You are also required to backup /etc/passwd and /etc/shadow when necessary if you have more than one user.

That's all. See you!

HOWTO : MyGica D689 USB HDTV Dongle on Ubuntu 9.10

We can watch digital TV including HDTV on Ubuntu 9.10 with MyGica D689 USB HDTV dongle. You may also require to buy a new nVidia series 9000 or up display card. Since series 9000, nVidia display card supports hardware acceleration for playing HD video.

In order to keep my Ubuntu box easy for update and secure, I prefer to install software packages from official and PPA repositories. However, I need to compile the MyGica driver in order to make it works. Only gXine works out of box without compilation.

Hardware and software used in this tutorial :

CPU - AMD Athlon 64 x 2 4200+
RAM - 8GB DDR2 800
Hard Drive - 320GB x 2 on Hardware RAID 0
HDTV - MyGica D689 HDTV USB dougle (v3.0)
Display card - XFX nVidia GT240 with 1GB DDR3 RAM and HDMI
Operating system - Ubuntu 9.10 Desktop AMD64 with Kernel 2.6.31-16-generic

The following procedures are for installing PPA nVidia display driver.

Step 1 - Add essential repositories :

(A) Add medibuntu repository (for general multimedia codecs and plugins)

sudo wget http://www.medibuntu.org/sources.list.d/karmic.list --output-document=/etc/apt/sources.list.d/medibuntu.list &&
sudo apt-get -q update &&
sudo apt-get --yes -q --allow-unauthenticated install medibuntu-keyring &&
sudo apt-get -q update

** Note : If you are using Ubuntu Samiux Remix, you are not required to add this repository as it is already added.

(B) Add nvidia-vdpau repository (for related VDPAU libraries)

echo "deb http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu karmic main" | sudo tee -a /etc/apt/sources.list.d/nvidia-vdpau.list
echo "deb-src http://ppa.launchpad.net/nvidia-vdpau/ppa/ubuntu karmic main" | sudo tee -a /etc/apt/sources.list.d/nvidia-vdpau.list

Add key of nvidia-vdpau repository to the keyrings.

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys CEC06767

sudo apt-get update
sudo apt-get upgrade

** Remarks : Or, you can use this command
sudo sh -c 'echo "Test I want to write" > /path/to/file'

Step 2 - Install all related softwares, codecs and plugins :

sudo apt-get install x264 gxine gxineplugin mencoder mplayer-nogui

** Note : If you are using Ubuntu Samiux Remix, you are not required to install the following codecs and plugins.

sudo apt-get install ubuntu-restricted-extras quicktime-utils quicktime-x11utils libdvdnav4 libdvdread4 libdvdcss2 non-free-codecs faad

** Note : If you are using Ubuntu Samiux Remix, you may need to uninstall mplayer as it cannot work properly.

Then, reboot your system.

Step 3 - Install nVidia display driver

Select "System" - "Administration" - "Hardware driver" from the menu on the desktop.
Choose nVidia display driver 190 version as prompted. After the install, you are required to reboot your system.

After the reboot, you should install the following package.

sudo apt-get remove nvidia-settings
sudo apt-get install nvidia-settings-190

Step 3a - Alternative way to install nVidia display driver (Optional)

** Note : Choose Step 3 or 3a only but not both of them.

Uninstall the following package.

sudo apt-get remove nvidia-settings-190

Download the latest beta nVidia display driver 195.22 (as on 2009-11-28).

x86 version :
wget ftp://download.nvidia.com/XFree86/Linux-x86/195.22/NVIDIA-Linux-x86-195.22-pkg1.run

x86_64 version :
wget ftp://download.nvidia.com/XFree86/Linux-x86_64/195.22/NVIDIA-Linux-x86_64-195.22-pkg2.run

Install nVidia latest beta driver (195.22)

sudo apt-get remove nvidia-settings-190

sudo service gdm stop

It will go to command mode.

sudo sh NVIDIA-Linux-x86-195.22-pkg1.run

or

sudo sh NVIDIA-Linux-x86_64-195.22-pkg2.run

Follow the instructions on the screen to complete the installation.

sudo service gdm start

Reboot your system to make the driver activate.

For uninstall nVidia display driver :

sudo sh NVIDIA-Linux-x86_64-195.22-pkg2.run --uninstall
sudo sh NVIDIA-Linux-x86-195.22-pkg1.run --uninstall

** Note : If your kernel is updated, you should install the nVidia again.
** Note : Manual install of nVidia driver will overwrite some of the PPA's files. When you uninstall the driver, you need to reinstall the PPA's driver and libraries.

***The following procedure is for reinstall the PPA's driver after uninstalled manual installed official driver.

sudo service gdm stop
sudo apt-get --reinstall install nvidia-settings-190 nvidia-190-libvdpau nvidia-glx-190 nvidia-common nvidia-190-kernel-source xserver-xorg-video-nv nvidia-190-modaliases

sudo reboot

Download links for latest nVidia driver :

* This "channels.conf" is for HONG KONG only.
** The first entry of the "channels.conf" will be played once it is activated.

Then, copy the channels.conf to ".xine" directory.

cp .config/gxine/channels.conf .xine/channels.conf

Or, you can scan your own.

sudo apt-get install dvb-apps

scan /usr/share/dvb/dvb-t/hk-HongKong > channels.conf

Step 7 - Further configure gXine :

(A) Select "File" - "Configure" - "Perference" on the gXine control panel. Make changes as is.


gui : experience_level (Expert)

audio : a52 : dynamic_range (enabled)
audio : a52 : surround_downmix (enabled)
audio : a52 : level (200)
audio : volume : mixer_volume (100)
audio : volume : remember_volume (enabled)

media : dvb : tuning_timeout (3500)
media : dvb : remember_channel (disabled) *Enabled if you want
media : dvb : channels_conf (select .config/gxine/channels.conf)

engine : performance : memcpy_method (libc)
engine : buffers : video_num_buffers (519999)
engine : buffers : video_num_frames (50)


** Other settings be keep them untouched.

(B) Select "Audio" - "Configure Plugins" - "Audio Post-processing" on gXine control panel.

Add/Change "volnorm" - "properties" - "method" (1) and apply the change.

(C) Select "Video" - "Configure Plugins" - "Deinterlace" on gXine control panel.

Add/Change "tvtime" - "properties" - "method" (use_vo_driver) and apply the change.

(Ca) Select "Video" - "Configure Plugins" - "Deinterlace" on gXine control panel.

Add/Change "pp" - "properties" - "quality" (39) - "mode" (vb) and apply the change.

(Cb) Select "Video" - "Configure Plugins" - "Deinterlace" on gXine control panel.

Add/Change "pp" - "properties" - "quality" (39) - "mode" (ha) and apply the change.

(Cc) Select "Video" - "Configure Plugins" - "Deinterlace" on gXine control panel.

Add/Change "pp" - "properties" - "quality" (39) - "mode" (va) and apply the change.

*If you find video playback chopping, you should applied this setting. Step 7 (Ca) to (Cc) are useful for an old CPU.

(D) Select "Video" - "Configure Plugins" - "Video Post-processing" on gXine control panel.

Add/Change "tvtime" - "properties" - "method" (LinearBlend) and apply the change.

Step 8 - Watch HDTV :

Run gxine from the "Application" - "Mutimedia" - "gXine".

Click on "File" - "DVB" or "Playlist" to watch TV on gxine. If you just start the gXine, you should click "DVB".

(A) Watch HDTV :
On the control panel, select "Video" and uncheck "Post-processing" and check "DeInterlace". Otherwise, the video and sound cannot be synchronized.

e.g. Jade HD and aTV HD

(B) Watch Digital TV and Standard TV (analog) :
On the control panel, select "Video" and check "DeInterlace" and "Post-processing". Otherwise, the playback will be chopping.

Step 9 - Test your MyGica D689 (Optional) :

Insert your MyGica D689.

lsusb

The output should be :
Bus 001 Device 002: ID 0572:d811 Conexant Systems (Rockwell), Inc.

The following is for testing purpose.

sudo apt-get install dvbsnoop dvbtune

dvbsnoop -s signal

If there is some output but not error, your MyGica D689 works.

Step 10 - Streaming TV on LAN and recording TV programmes (Optional and not tested by me) :

This is work of "ksng".

Download ksng's scripts (dated 2009-NOV-26)
Download ksng's scripts (dated 2009-DEC-05)
Download ksng's scripts (dated 2010-FEB-04)

Known Issue :

(1) Make sure your signal strenght of digial TV is strong enough and your MyGica D689's antenna should be placed near or at the window. It is because signal strength detection does matter. Otherwise, your playback will be chopping and lagging as well as stuttering and distorting or even channels shifting. An amplifier is required at my area of testing.

(2) Xine decoder is coded by Xine team and the CPU power consumption is very high. Thus, more powerful CPU is required. The playback of HDTV (such as Jade HD and aTV HD) (1920x1080) is chopping under the testing hardware (Athlon 64x2 4200+ CPU). This CPU is launched around 2006. Another test with version 195.22 driver also has the same problem on my testing hardware.

**The chopping playback is solved by applied Step 7 (Ca)-(Cc). My Athlon 64x2 4200+ is too old to run the modern technology! The playback is just acceptable only.

(3) nVidia display driver version 190.42 does not support video post-processing and multi-threading. However, the beta driver (195.22 or later) may solved the multi-threading problems.

(4) Compiz runs flawless while watching HDTV, superise?!

(5) Mplayer (from official Ubuntu repository and nvidia-vdpau repository) does not work properly.

(6) Standard channels does not work properly at my side. May be the signal is not strong enough. However, when an amplifier is applied, the problem is solved.

(7) Me TV cannot record the TV programmes and HDTV may not play properly.

(8) When the kernel is updated, you need to delete the driver directory and build as well as re-install again.
