Adrenaline v2.5 stability fix

I’ve received several reports from users that Adrenaline Gnome freezes quite a lot. It’s true. It does. And we need to fix it right away!

Tracing the problem, I’ve come to the conclusion that it’s some way related to the Gnome Terminal. To check if I was right or not, I did a week long experiment. I removed Gnome Terminal entirely and replaced it with Terminator – a really powerful yet simple Terminal Emulator. And it worked! It’s been a week and my Adrenaline Gnome has not frozen even once. It’s as stable as Synergy!

Time to stabilize our beloved Adrenaline Gnome! Let’s do this!

Step 1: Remove Gnome Terminal

Start Root Terminal (Menu -> System Tools -> Root Terminal). Then give the following command:

aptitude purge gnome-terminal

Don’t close Root Terminal just yet. We’ve to install Terminator!

Step 2: Install Terminator

Let’s first update the repos. Give the following command:

apt-get update

Now let’s install Terminator:

apt-get install terminator

Wait for a moment as the system will download and install Terminator. Once the process is complete you may close the Root Terminal with the following command:

exit

Done!

Step 3: Update Adrenaline. (Not optional)

It’s important that you update Adrenaline to the latest packages. Follow this tutorial to update Adrenaline:

Step 4: Terminator preferences (Optional)

If you’d like to change colors and fonts in Terminator, it’s easy. Right click anywhere inside the Terminator window and select ‘Preferences’. A new window will open up where you can customize Terminator in any way you like. Here’s my Terminator customized to look like the standard Gnome Terminal:

Terminator - a powerful yet simple Terminal Emulator

Now when you select ‘Root Terminal’ from the menu, it will automatically start Terminator with root privileges as shown in the picture above.

All done! Adrenaline is now as stable as Synergy. No more freezes. No more irritations. No more loss of work!

Let me know if this works out for you. If you’re facing issues, email support is always available.

Namaste!

 

Enabling Auto Login in Adrenaline v2.5

Autologin, as the name suggests, logs the user in the system without asking the initial username and password. By default, this facility is disabled in Adrenaline. But it’s quite easy to set it up. Follow the steps below.

Setting up AutoLogin in Adrenaline Gnome:

1. Hit ALT + F2. In the text box that opens up, give the following command and hit enter:

gksu gedit /etc/gdm3/daemon.conf

Open the daemon.conf file in Gedit for editing
This will open up the gdm3/daemon.conf file in Gedit Text Editor. We’ve to make some changes to this file.

2. Now carefully find these lines:

[daemon]
# Enabling automatic login
# AutomaticLoginEnable = true
# AutomaticLogin = user1

Next, remove the ‘#’ symbol from the last two lines. Also add your username in place of ‘user1’. My username is ‘utkarsh’. This is how my code snippet looks:

[daemon]
# Enabling automatic login
 AutomaticLoginEnable = true
 AutomaticLogin = utkarsh

Take a look at the screenshot below. I’ve highlighted the lines for you.

Un-comment the lines to enable autoLogin

3. That’s it. Save the file, close Gedit and restart your computer. The system will log you into Gnome session automatically from now on. Just in case you wish to disable autologin, just add ‘#’ symbol to those lines again. Simple!

Setting up AutoLogin in Adrenaline Mate:

1. Hit ALT + F2. Then in the text box give the following command:

gksu pluma /etc/lightdm/lightdm.conf

This will open the ‘lightdm.conf’ file for editing in Pluma Text Editor (similar to Gedit).

2. Now search the line that says ‘autologin-user’. Remove ‘#’ symbol at the beginning of the line and after ‘=’ symbol add your username.

Example:

autologin-user=utkarsh

Here, ‘utkarsh’ is my username.

Refer to the screenshot below. I’ve marked the line for you.

Open the lightdm.conf file in Pluma for editing

3. Save the file and close Pluma Text Editor. Restart your computer. Auto login should work in Adrenaline Mate now.

Done!

If you need any help, please comment or send an email. I’ll be right here to help you out!

Namaste!

Creating a Live USB – Adrenaline v2.5

We’re going to view two of the best programs available to create Live USBs – Unetbootin and YUMI. Unetbootin is a cross platform app available for Windows, Mac and Linux. YUMI is Windows-only. To create Live USB of Rebellin Adrenaline, there are some important considerations:

1. A flash drive with 4 GB capacity or more is recommended

2. Flash drive should be formatted with the FAT filesystem

3. Your computer should be able to boot through USB devices

That’s about it. The process is very simple. So I’ve provided only a single screenshot for each app.

Unetbootin:

1. For Windows and Mac, you can download Unetbootin from its official SourceForge Page. If you wish to use Unetbootin on Linux, it is recommended that you install it via the official repositories of your distribution. In Rebellin, you may give the following command in Root Terminal

apt-get update
apt-get install unetbootin

This will install Unetbootin and all the required shared libraries. Unetbootin should turn up in the ‘System Tools’ section of the menu.

2. Launch Unetbootin and in its bottom section, select the following:

Select ‘Disk Image’. Then click on the button with ‘three dots’ and select the iso image of Rebellin Adrenaline.

Then below, in the first drop-down, select USB Drive. And in the next drop-down, carefully select your flash drive.

Rebellin DOES NOT work well with persistence storage. Make sure the text box says ‘0’ in the ‘Space used to preserve files across reboots’ option!

Now click on the ‘Ok’ button

3. Done! Unetbootin will now write the ISO image to your flash drive. Reboot your computer once the process is complete.

Unetbootin Live USB creator

YUMI:

YUMI (Your Universal Multiboot Integrator. Phew!) is a Windows-only app. But this one can create a multi-boot flash drive. That is, you can write multiple Linux distro ISOs in the same flash drive. For simplicity we will be creating a simple Live USB with the Adrenaline ISO image. Follow these steps:

1. Download YUMI executable from the PenDriveLinux.com and launch it.

2. Now make sure your selections are as follows:

In the first drop-down, select your flash drive. Also tick the ‘We will format’ checkbox.

In the distributions drop down list, select ‘Debian Live’.

Hit the ‘Browse’ button and select the Adrenaline ISO image on your computer.

3. Hit the ‘Create’ button below.

YUMI will start the process. It takes some time for the process to complete. Once that’s done, you may use this flash drive to launch Rebellin Adrenaline.

yumi multiboot creator

That’s it! You may now use this flash drive to run Rebellin in live mode or for installations.

If you’re facing any difficulties, write a comment or shoot me and email!

Installing NVidia Drivers in Adrenaline v2.5 (DKMS Method)

DKMS Method is a ridiculously simple way to install NVidia drivers in Adrenaline and it takes hardly 10 minutes! The process is painless, even for newbies and is therefore highly recommended. We will use DKMS – Dynamic Kernel Module Support for installing these drivers. DKMS allows adding new kernel modules on-the-fly with no need to compile the kernel from source. This way even if the kernel gets an upgrade, the modules are compiled automatically. You don’t have to install the drivers again.

Yes, since we’ll be using packages from the repo, the drivers won’t be the most recent ones. But trust me, they work very well and you don’t really need the latest drivers unless it’s for some specific task.

Fire up the Root Terminal (Menu -> System Tools -> Root Terminal) and we’ll begin the process.

Step 1: Update the repos:

Let’s update the repos first. Give the following command:

apt-get update

Step 2: Install NVidia Drivers and related packages

IMPORTANT: This will install NVidia drivers for a discreet graphics card. If your computer is powered by NVidia Optimus, do not install drivers this way. Driver installation for Nvidia Optimus is covered immediately after this section.

So, to install NVidia drivers just give the following command:

apt-get install nvidia-kernel-dkms nvidia-glx nvidia-xconfig nvidia-settings

This command will install the NVidia Drivers and other related packages. If the system gives you a message about ‘Conflicting Nouveau kernel module loaded’, just press the OK button.

For NVidia Optimus:

Nvidia Optimus powered computers can switch between Intel and NVidia graphics cards on-the-fly. This conserves battery when performance is not needed. To install drivers for such a system, give the following command:

sudo apt-get install bumblebee-nvidia primus

Bumblebee is the driver that does the trick. It will automatically switch to the discreet graphics card if performance is needed, for example, while playing Full HD videos. At other times, your onboard Intel GPU will be used.

IMPORTANT: Optimus installation is over right here. DO NOT follow the steps given below. DO NOT run nvidia-xconfig. You’re done with the installation. Just restart your system.

Step 3: Update xorg.conf file:

We will now update your ‘xorg.conf’ file so that the system uses the new NVidia Driver. Before that, let’s back up your old ‘xorg.conf’. Very useful, just in case the new xorg.conf doesn’t work then we’ll need our old settings back! Give the following command:

mv /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

If you get an output saying – ‘No such file or directory’, no problem. Just go ahead with the following command:

nvidia-xconfig

The NVidia Utility will create the new xorg.conf file for you which will point to Nvidia Drivers we just installed! Great!

And you’re done! Restart your computer. Congratulations! Adrenaline is now using NVidia Video Drivers.

Step 4 (Optional): Install VDPAU library:

The Video Decode and Presentation API for Unix is a library used to decode video on the graphics card, thus improving the overall video playback performance. This library works only on GeForce 8 series or higher graphics cards from NVidia. Roughly, the VDPAU is equivalent to Microsoft Direct X Video Acceleration (DxVA). If you wish to install it, give the following command:

apt-get install nvidia-vdpau-driver vdpau-va-driver

That’s it. A reboot is recommended.

Let’s wrap it up here. If you need any help, just ask! I’m always happy to help!

Namaste!

Installation: Adrenaline v2.5

While most other Debian based Linux distributions have their own custom installers, we decided to go with the standard Debian Installer. There are several advantages of this method. The most obvious one being the ‘Easy Mode’ and the ‘Advanced Mode’ depending upon the available install-time customizations to the OS. This tutorial shows you the easiest way by which you can install Rebellin Adrenaline on your computer.

The Adrenaline installer is bundled out of the ‘live’ mode. This enables you to install Adrenaline on a system with very low system resources as you need not boot into live mode. Here’s the process. We assume you have Windows installed on your computer, so this tutorial teaches you to install Adrenaline alongside Windows. We also assume that you have at least 10GB of contagious free space or an empty partition, which can be used to install Adrenaline.

IMPORTANT! Please disable your internet connection – WiFi/Ethernet/USB before you proceed.

Step 1: Boot the DVD

Put the DVD in your computer and reboot. You will come across the Rebellin Adrenaline DVD boot screen. If not, you may have to adjust your BIOS settings to boot through the DVD. Once you are here, select GUI Install

Adrenaline Boot Menu

Step 2: Choose your language

In the next screen, choose your language. And then click continue.

Choose language for the installed system

The language you choose here will be the default language for the installed system.

Step 4: Configure the keyboard

In this screen, choose your keyboard layout. If you’re unsure about your keyboard, choose ‘American English’. It’s the most standard form of layout available all over the world.

Configure your keyboard

Step 5: Network Configuration

Depending on your computer hardware, the installer may ask you if you wish to load missing firmware from the removable media (additional DVD/USB)?. The answer is no! Adrenaline is designed to configure automatically on first boot. There is no need of any spoon feeding from the installer. And as such, there is no additional ‘firmware disk’ shipped with Adrenaline anyway! ;)

So select ‘No’ on the next screen and hit ‘Continue’.

There is no need to load missing firmware

If your computer has multiple network interfaces, such as wifi and ethernet, the installer would ask you to choose the default interface to be used. In such a  situation, select the ethernet interface (eth0 in this case) as the default one.

Choose default network interface

The installer will then attempt to configure the network automatically. This configuration may fail and the installer will display the following on the screen. Even otherwise if you are confused at this step, you can safely skip it. Just click on continue if the screen looks something different than what is shown below:

Network configuration may fail. It is normal.

When you click ‘Continue’ here, you will be taken to the following screen. On this screen select ‘Do not configure the network at this time’ and click ‘Continue’.

Skip the network configuration step

Step 6: Enter a hostname

Enter a hostname for this computer. Hostnames are used to identify your computer over a network. For example, if this computer is part of a LAN. Don’t think too much, ‘rebellin’ would do fine in the text box. ;)

Enter a hostname

Step 7: Set up users and passwords

On this screen, enter a root password. ‘Root’ user is the administrator of the system and has the privileges to alter any system settings. Each time a users attempts to make important changes, he will be asked for this root password. If no root password is supplied, a normal user can use ‘sudo’ command to gain temporary root-level privileges. We recommend you to create a root password and do not share it with anyone, unless you want them to make significant changes to the system. Mind you, users fooling around with root privileges can screw up the whole system.

Choose a root password

Step 8: Enter your full name

Enter full name for the user in this screen.

Enter your full name

Step 9: Username and Password for your account

Here, provide a username. By default, the installer may select your first name as the user name. If you are fine with it, select continue. If not, make something up here and click continue.

Enter a username

In the next screen, create a password. This is not the root password. This will be the password for YOUR account, and can be used for logging into the system. However, if no root password was selected in the previous step and your account is the first account on the system, you can get temporary root privileges by using the ‘sudo’ command. You will then be asked for your password, which if found to be correct, you will be granted temporary root privileges.

Set password for the user

Step 10: Partition set up for Adrenaline

This is a very important step. Once you are done creating users for the system, the installer will start the inbuilt partition manager. We assume you have Windows installed on your hard drive and you wish to install Adrenaline alongside it. For this purpose select ‘Manual’ in the options below. Selecting ‘Guided’ may completely wipe your entire hard drive!

Choose manual partition mode

As you can see in the image below, I’ve got 33.7 GB of free space. We have to create 2 partitions in this free space. So ‘double click’ on the free space.

Create partitions in free space

You will then be taken to the next window. Here select ‘Create a new partition’ and click ‘Continue’.

Create a new partition

The partition we are about to make, will be used for installing the Operating System. This means, it has to be sufficiently big. Therefore, of the 33.7 GB of Free Space I have selected 33 GB for this partition. You can enter a comparable value in the text box, just make sure it’s sufficiently large. But don’t use the entire partition as we have to create one more! For example, if you have 10GB of Free Space, you can use 8.5 – 9GB for this partition. Enter a value here and click ‘Continue’.

Parititon size for root partition

In the next window, select ‘Beginning’ and click ‘Continue’.

Create partition at the beginning

You will then be taken to the next screen. Double click to change settings here. Set the values as follows:

1. In ‘Use As’, select ‘Ext4 journaling file system’

2. In ‘Format the partition’, select ‘yes, format it’ (This option may not be visible if partition is new)

3. In ‘Mount point’ select ‘ / ‘

Leave everything as it is. Select ‘Done setting up the partition’ and click ‘Continue’.

Create Root Partition

All done? Excellent! Just a little more patience, and we’ll be through with the installation. On to the next screen then, here’s what you should find –

Select the remaining free space

As you can see, a new 5th partition was added, the one we just created. Now have to create just one more, the last one. Double click on the ‘Free Space’ to start the process of partition creating again. Select ‘Create a partition’. I’ve 669.3 MB remaining. Let’s use all of that. So keeping the numbers in the textbox unchanged, just click on ‘Continue’. Then select ‘Beginning’. For me, this will be a logical partition as well.

Select all remaining space

In the next screen. double click to change settings. Use the following value:

1. In ‘Use As’ select ‘swap area’

Let everything else be as it is. Select ‘Done setting up the partition’ and click ‘Continue’.

Create Swap Partition

A new ‘Swap Partition’ will get added to the list of your partitions. Swap area is used when the amount of RAM in your computer is low for the programs to run. Yes, it’s similar to ‘Virtual Memory’ in windows. We’re finally done with all the partitioning. Now select ‘Finish Partitioning and write changes to disk’ and click on ‘Continue’.

Creating partitions is complete

The installer will ask for confirmation whether all the changes are correct or not. As you see in the screenshot above, the partitions we created were numbered 6 and 7 (though chronologically they are 5th and 6th). The same numbers are represented in the following screen. This shows everything is okay. Go ahead, select ‘Yes’ and click ‘Continue’.

Write partitions on the disk

Done? Awesome! The installer will now create the partitions and will begin installing the Operating System on your computer. This process make take about 20-25 minutes. Make yourself a cup of coffee and relax.

Step 11: Package Manager Configuration

Once the installer has copied all the files to the partitions we made, it will scan and attempt to configure a network mirror for the package manager. Network mirror is basically the Debian repository closest to your location from where you can download software packages. It’s not gonna work. Why? Cos I’d asked you to disable your internet! Don’t worry. Rebellin will set itself automatically on first boot and there is no need of this spoon feeding from the installer. So when the installer asks you to ‘Continue without a network mirror?’, select ‘Yes’ and click on ‘Continue’.

Continue without a network mirrorStep 12: GRUB Configuration

In the next screen you will asked whether to install GRUB in the master boot record of your hard drive. GRUB is the boot loader used for starting up the systems installed on your computer. GRUB will provide you with a menu where you can select your desired OS to start – Adrenaline or Windows.

Go ahead, select ‘Yes’ and click on ‘Continue’.

Install Grub bootloader

Step 13: Installation complete. Reboot!

Once GRUB installation is finished, the installer will check whether all the steps have been completed and will display the ‘Installation Complete’ screen. Congratulations! You have successfully installed Rebellin Adrenaline in your computer. You are now ready to fire up the new system. Click on ‘Continue’ to reboot. Adrenaline disk will be automatically ejected. Remove it so that the installed system starts.

Installation Complete

Step 14: Help us! 🙂

Oops! Thirteen is an unlucky number and we’re quite a superstitious lot! So here’s step 14. Do tell all your friends about Rebellin Linux. Help us grow! Cheers!

I hope all my instructions were clear. If you still have any problems, please feel free to comment. I will definitely solve all your troubles. Enjoy your new Linux world.

Namaste!

Updating Adrenaline (v2.5)

Adrenaline has to be updated manually. Now that’s a little disappointing. But if you look at things our way, it’s actually a better move. Sometimes a step back is necessary. Here are the main reasons why we decided to go for the last-century-not-so-cool-manual-update-mechanism:
1. Update manager runs its own process in the background, and this process may interfere with manual installations being carried out by the user via the root terminal.
2. The process consumes some resources and slows the system a bit. The slowdown is pretty apparent on low powered systems.
3. Prompts asking for root password come up randomly and this may confuse the user as nothing really happens on screen when you give the password!
4. Update manager may actually fail to properly update the system leading to breakages. This does happen!
5. Users like me who prefer sticks to automatics – when things are in our total control, they run better!
6. Save internet resources – for regions where bandwidth is pricey and scarce.

Well, now let’s get on with the process. It’s ultra simple. It’s highly recommended to update Adrenaline via the Synaptic Package Manager.

Start Synaptic Package Manager

For Gnome Shell: Menu -> System Tools -> Synaptic Package Manager.

For Mate: System -> Administration -> Synaptic Package Manager.

Enter your root password in the prompt and Synaptic starts.

Synaptic in Adrenaline Mate

Now it takes just 3 steps to update Adrenaline:
1. Click the ‘Reload’ button. This will update the repos.
2. Click the ‘Mark All Upgrades’ button. This will mark the packages that will be upgraded.
3. Click the ‘Apply’ button. Synaptic will display a summary of the update process.
That’s it. Synaptic will download and apply the updated packages. A reboot is recommended.

If you wish to go via the command line way, then here’s the process:

Fire up the Root Termianl (Menu -> Accessories -> Root Terminal) and give the following commands:

apt-get update

apt-get dist-upgrade

Apt will show you a summary of the process and will ask for your permission to continue. Enter ‘Y’ and let the process complete. Once done, a reboot is highly recommended. That’s it.

Manual update of Adrenaline is complete. You can update Adrenaline any time you wish: once a week should be perfect! If you have face any difficulties, email support is always available.

Namaste!
