[ Tutorial ] Reinstall Grub 1 and Grub 2 on Ubuntu

Windows bootloader will overwriten Linux GRUB bootloader if we reinstall windows on a computer with dual boot OS.Now follow this tutorial to restore GRUB1 and GRUB2

GRUB1
boot with livecd or liveusb
open terminal
follow this step

sudo grub
grub>find /boot/grub/stage1
grub>root (hdx,y)
grub>setup (hdx)
quit

*note x and y is the output of grub find /boot/grub/stage1.The output may different on different machine

GRUB2
boot with ubuntu 9.10 livecd/liveusb(the current version of ubuntu that using the newest grub2 version is ubuntu 9.10 when i am writing this article).
open terminal
write the following line on the terminal
$sudo -i
#mount /dev/sdax /mnt
#grub-install --root-directory=/mnt/ /dev/sda
#exit

note:x is your root linux partition

GRUB2 didn't recognize another OS automatically so we have to do that manually.It's not that hard just type the following command in terminal

$sudo update-grub

This will reconfigure the list of title and detect another OS like Windows.

[ Tutorial ] How to make Ubuntu sound better

I am using Ubuntu 8.10 when writing this tutorial.

The default sound driver on ubuntu 8.10 and other major linux distribution is ALSA(Advanced Sound Linux Architecture). ALSA has a standard sound quality and has embedded generic sound driver.If you need high quality sound for multimedia computing such gaming,HTPC(Home Theater PC),Sound Editing,or listening music with more detailed sound, you should replace the ALSA driver with OSS(Opensound System) which provide a better sound for multimedia computing

What is OSS(it's Opensound System so don't mispronounced it with OSS opensource sofware ) ? OSS is a digital audio solution that provide a better sound in Unix varian that developed by 4front technologies, and thanks to them my experience in listening music is become enjoyable. If you ever experienced that the output of your sound in Ubuntu is small and weak you should try this amazing audio replacement.

Well, that's enough for the chit chat now let's get to the tutorial how to install it.
You need to disable your ALSA before you can install OSS,here is the steps:
Type this following text on terminal:

sudo chmod 776 /etc/modprobe.d/blacklist
sudo cat /lib/linux-sound-base/noALSA.modprobe.conf >> /etc/modprobe.d/blacklist

This following text is one command so make sure you type it correctly ! :

sudo echo "blacklist snd_hda_intel
blacklist snd_mixer_oss
blacklist snd_pcm
blacklist snd_timer
blacklist snd_page_alloc
blacklist snd_hwdep
blacklist snd
blacklist soundcore" >> /etc/modprobe.d/blacklist

if you done now you can download the OSS from here and choose the debian package file .deb
and then you can install it by simply double click that package file or from terminal type :

sudo dpkg -i theOSSfileyoudownload.deb

There is alot of people who have a mute Ubuntu system after installating the OSS, this problem occur simply because they are not running this following command to test their output sound:

osstest

Note: The login and logoff jingle will never be exist anymore after you installing OSS.If you use ubuntu 8.04 or older you can install ESD(Enligtment Sound Daemon) to get back the jingle sound.In terminal you type(must be connected to internet):

sudo apt-get install -y esound esound-clients esound-common libesd0

Unfortunately when i am writting this post for Ubuntu 8.10 and newer you must wait for it's compatibily to use ESD.

That's all for now,i hope you are enjoying your new multimedia sound experience.
See you in the next tutor.

ROMINUX LAUNCHING !
