xx Acer ES1-531 - getting Linux to boot
July 08, 2017, 02:34:03 pm by Lotta Lumina
I decided to install Xubuntu 17.04 today, and if anyone here has an Acer ES1-531 computer (which is what I use), or similar modern Acer that uses UEFI and cannot get Linux to boot after restarting (and the installation process completing) follow these instructions:

1. Boot into BIOS. You may be prompted for a password, enter it.
2. Enable 'Secure Boot' in 'Boot' setting if it is not enabled already.
3. Go to 'Security' and click 'Select an UEFI file as trusted for executing'.
4. (In the case of Ubuntu+GRUB) find HDD0 > ubuntu > shimx64.efi
5. Name it something relevant such as 'Xubuntu'
6. Restart, saving changes, and boot back into BIOS
7. Push 'EFI File Boot 0' to the top of the listing in 'Boot' setting.
8. You should be able to boot into GRUB.

You can turn Secure Boot off again if you wish to after step 8. It does not remove the additional boot entry that you added.
thumbup What is Redis
March 21, 2016, 05:42:54 pm by dr10hiten
It's a "NoSQL" key-value data store. More precisely, it is a data structure server. The closest analog is probably to think of Redis as Memcached, but with built-in persistence (snapshotting or journaling to disk) and more datatypes

    xx How To Install VirtualBox Through PPA In Ubuntu 14.10/14.10 Or Other Distributio
    January 14, 2015, 12:51:59 pm by MohdSohail
    Recently I posted a video in our video tutorials page on "How To Install Genymotion And Run Android Apps (Whatsapp) On Ubuntu 14.10/Linux Mint Or Others Video Tutorial".  I was asked for simpler way of installing VirtualBox instead of downloading package from website and depackaging it through dpkg. So here you can also install it from ppa. Although you can directly open .deb file in software center that will install quickly but those who are familiar with repository then you can do it with adding ppa also.

    VirtualBox is used to install another virtual operating system inside one operating system. If you want to know more about VirtualBox then read here.

    Install VirtualBox using ppa

    First of all install dependency for VirtualBox.

    Code: [Select]
    sudo apt-get install dkms
    Add ppa

    To add ppa and key use the following commands -

    Code: [Select]
    wget -q -O- | sudo apt-key add -
    Add the public key to your repository that you just installed

    For Ubuntu 14.04

    Code: [Select]
    sudo sh -c 'echo "deb trusty contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 13.10

    Code: [Select]
    sudo sh -c 'echo "deb saucy contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 13.04

    Code: [Select]
    sudo sh -c 'echo "deb raring contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 12.10

    Code: [Select]
    sudo sh -c 'echo "deb quantal contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 12.04

    Code: [Select]
    sudo sh -c 'echo "deb precise contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 11.10

    Code: [Select]
    sudo sh -c 'echo "deb oneiric contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    For Ubuntu 11.04

    Code: [Select]
    sudo sh -c 'echo "deb natty contrib" >> /etc/apt/sources.list.d/virtualbox.list'
    Now its time to update  your repositories

    Code: [Select]
    sudo apt-get update

    Now Its Time To Install VirtualBox

    Code: [Select]
    sudo apt-get install virtualbox-4.3

    If you want to install any other version then just replace 4.3 with whatever the version you want, like, 4.2 or 4.1

    It's all done! You've installed VirtualBox open it from dash by typing 'virtualbox'.

    xx How To Use 'Sudo' And 'Su' Commands In Linux : An Introduction
    January 11, 2015, 09:42:26 am by MohdSohail
    How To Use 'Sudo' And 'Su' Commands In Linux : An Introduction

    Today We're going to discuss sudo and su, the very important and mostly used commands in Linux. It is very important for a Linux user to understand these two to increase security and prevent unexpected things that a user may have to go through. Firstly we will see what these commands do then we'll know the difference between both of them. So let's get started.

    Introduction to Linux command 'sudo'

    In Linux there is not root account configured by default. If users want root account password then they can manually set it up oo can use 'sudo'. As we all know, Linux in many ways protects users' computer being used for bad purposes by some nasty people around us. Using sudo is one of those good ways. Whenever a user tries to install, remove and change any piece of software, the user has to have the root privileges to perform such tasks. sudo, linux command is used to give such permissions to any particular command that a user wants to execute. sudo requires the user to enter user password to give system based permissions. For example user wants to update the operating system by passing command -

    Code: [Select]
    apt-get update

    The above command will give following error-

    This error is due to not having root privileges to the user 'sandy'. The root privileges can be required by passing sudo at the very beginning, like below-

    Code: [Select]
    sudo apt-get update

    The above command will execute command and the operating system will update-

    As you can see when I used apt-get update that is a packaging management tool and through that I tried to update my system but it failed because to make this command work for me, I must have root privileges. So the next time I used the same command along with 'sudo' and this time sudo command asked user password to have root privileges to update system. After entering user password it system updated.

    But there may not be all the user accounts able to use sudo. As a system administrator, he has to give the rights whether any particular user can sudoer to do particulars admin tasks. To read that in description jump over here on the official page.

    Some more examples of 'sudo' -

    Code: [Select]
    sudo apt-get install {package-name}

     This command will install packages with the root privileges.

    Code: [Select]
    sudo apt-get remove {package-name}

     This command will remove packages with the root privileges.

    Code: [Select]
    sudo apt-get update {package-name}

     This command will update packages with the root privileges.

    Introduction to Linux command 'su'

    The Linux command 'su' is used to switch from one account to another. User will be prompted for the password of the user switching to.

    Code: [Select]
    $ su linuxandubuntu
    [email protected]:~$

    Users can also use it to switch to root account. If user ty
    pes only 'su' without any option then It will be considered as root and user will be prompted to enter root user password.

    Using 'su' command to have functionality similar to 'sudo'

    If user only uses 'su' command and want to use 'su' as 'sudo' then it can be done. (here root password is assumed to have been configured because user is familiar with 'su'.)

    To achieve same sudo functionality to execute any single command user has to use '-c' option of 'su'. Here is how to do it -

    Code: [Select]
    $ su -c apt-get install vlc

    After hitting enter user will be prompted for password and obviously it's for root password because we're using 'su' command.

    Using 'sudo' command to have functionality similar to 'su'

    Above we have seen 'su' having similar functionality as sudo and it's time to see how we can do same with the command 'sudo' and achieve same 'su' functionality.

    To achieve same 'su' functionality in 'sudo' just use '-i' option of 'sudo'. Here is how we can do it -

    When user hits enter, it will ask password its the user password not the root password.

    It's all done!

    You can learn more about these commands through man pages.

    Code: [Select]
    $ man sudo
    $ man su

    Congratulation! You now have the basic knowledge the mostly used commands in Linux.

    We'll learn more about these commands in our another post, like to create/configure root password manually etc.
