Ubuntu power users are able to accomplish amazing things with their system by changing settings and internal aspects inside of the operating system. It’s not too hard if you know you’re way around the system but for beginners, these skills are a little more difficult to master. To make up for this, consider using a tool like Ubunsys. It’s an advanced system tool that allows users change Ubuntu system settings. With it, users can easily modify the sudoer file, turn the firewall on and off, make passwords visible when typing in terminals, manage system updates and even clean up old kernel files.
Ubunsys is available for Ubuntu version 17.04 specifically. To install this program, you’ll need to add it to your PC via a custom repository. This custom repository is called a PPA. It allows developers to easily (and independently) deliver programs without consulting with Ubuntu developers. By adding this PPA to your system, you’ll be able to get constant updates from the developers.
Open up a terminal window, and enter the following commands:
If the PPA method doesn’t work, head over to this page and download the latest Debian package. Double-click on the package to start the installation process in the Ubuntu app store.
When it comes to using Ubunsys, there are many different options. It is because of this, we’ve decided to go over the most important options only. If we covered every single esoteric option in the program, it’s quite possible that this article would never end!
Enable Passwordless Sudo
One thing that new Linux users often complain about is how annoying it is to enter a password to do anything to the system. Want to install a program? Enter a password. Want to update your PC? Password, please. And that’s how it goes. For some, this is a great feature, as it prevents unauthorized changes.
Still, if you’re a beginner Linux user, and you’re coming from an operating system that allows you to do whatever you want to your system without the need for passwords, this can get a little annoying. Luckily, this is easily fixed with Ubunsys.
Open Ubunsys, click on “Tweaks”, look for the option to “enable sudo without pass” and click on it. Turn this tweak back off by clicking “disable sudo without pass”.
Enable Sudo Password Feedback
Another annoying thing about entering passwords on Linux is the way it happens in the terminal. If you’re new user, you might have tried to enter a command in the terminal, only to have to enter a password. When you type out the password, you notice that the terminal isn’t doing anything.
Those not used to the terminal and Bash, may think that the password didn’t work. This is because Bash has no password feedback. With Ubunsys, there’s an easy way to fix this:
Go to Tweaks, and find “Terminal passwords”. Click the option to enable visible passwords.
Ubuntu has a great Firewall, but for some reason it isn’t turned on by default. Normally, doing this is a bit of an involved process. Luckily, Ubunsys has made turning on the firewall much easier. To do so, find “Tweaks”, then look for “System”. To enable the Ubuntu firewall, click the Enable firewall button.
Want to turn the firewall off? If so, click the “Disable firewall” button.
Most Linux distributions have a suspend function. It allows the user to suspend the current session to disk, and places the PC in a low power mode. For most people, this works great. However, there are some real drawbacks. When a PC is suspended, it never truly turns off. It only goes into low-power mode. This means if your laptop battery dies, so does your PC, even in suspend.
Luckily, Linux users have another option: Hibernate. Unfortunately, this is turned off by default. Want to turn it back on? Look in “Tweaks” for “Power”, and click the “enable hibernate” button. Turn it off again by clicking the disable button.
As Ubuntu updates, so does the Linux kernel. As a result, many different versions of the Linux kernel are installed concurrently. This is great because if one version breaks, users can quickly switch to a different one. However, it probably isn’t a good idea to have 15 different Linux kernel versions installed at one time on a PC, as it takes up space.
Not to worry! With Ubunsys, it’s easy to get rid of the versions you don’t need. First, click the “System” tab, then click the “Advanced user” tab. Look for the option to “clean ancient kernels” and click on it. This will remove all outdated, and unnecessary Linux versions from your PC.
When you’re not sure what is going on, it can be pretty scary to change Ubuntu system settings. That’s why it’s great that tools like Ubunsys exist. This tool can single-handedly give beginners looking to get more out of their system the power to do so, without having to search through manuals and complex forum posts.
