Introduction to qView

qView is born with a clear objective to be a practical and minimalist image viewer. That is to say that we will only have the image as the central protagonist and without even a menu bar, it’s just you and the image. It is created with QT technology and is OpenSource which allows us to verify the source code of the application.

About this the developers say

qView was designed from the very start to be as visually minimal and space-efficient as possible. No cluttered interface, just your image, and a title bar.

This makes it a very light and easy-to-use application on our system. It has proven that its load times are quite short and the use of computer resources is quite low.

Despite being so light and having a minimalist graphical interface, it is not lacking in features such as rotating, flipping, zooming, opening images from a URL, recent images, from another location. All of them can be accessed by right-clicking on the main interface.

And what about supported formats? Don’t worry about that because qView supports all common image formats including bmp, gif, jpg, png, tiff, and webp.

Install qView on Linux

The support provided by this application is great and there are many options available to install it.

For Ubuntu 20.04/ 18.04 as well as any distribution based on any of these versions, we have available a PPA:

sudo add-apt-repository ppa:jurplel/qview
sudo apt update

And finally, install the application:

sudo apt install qview

For Debian 10, we have to download a DEB file from the download site or by running

https://github.com/jurplel/qView/releases/download/4.0/qview_4.0-2_amd64.deb

And install it by running

sudo apt install ./qview_4.0-2_amd64.deb

Every time a new stable version is released, you will have to update the command.

For ArchLinux it is available from AUR.

For OpenSUSE you can run

sudo zypper in qview

In the case of any RPM package based distribution, you can download the package

wget -c https://github.com/jurplel/qView/releases/download/4.0/qview_4.0-2_amd64.deb

and install it with your distribution’s package manager.

Finally, you can download the APPImage format which is compatible with any Linux distribution. For many, it is the best way-

wget -c https://github.com/jurplel/qView/releases/download/4.0/qView-4.0-x86_64.AppImage

Conclusion

qView is an application whose main concept is minimalism but without losing functionality. Thanks to it we have an alternative to other image viewers more complex to use.

For those who don’t know, KaOS is a Rolling Release distribution inspired by Arch Linux and focused on KDE Plasma. So, you will always find recent versions of this desktop environment, as well as programs related to QT and others. Being Rolling Release it is constantly updated and this makes it unnecessary to reinstall it. However, new ISO images are often released so that those who wish to install it do not have to update many packages.

So now this new image of KaOS is available and now we will see the main news.

KaOS Image (2020.07) features

The first thing you’ll notice is that Calamares, this great universal Linux distribution installer, has started a migration of its modules to QML. For example, the keyboard module is also rewritten in QML, which now gives a much clearer overview of possible keyboard models, languages, and variants.

Moreover, this new image of KaOS includes new firmwares. This will make it much more compatible with more hardware without the need for user intervention.

While all of these new features are very important, it is also true that the most notable is the inclusion of KDE Plasma 5.19. This version, which is loaded with new features, makes the system live up to its promise of providing a satisfying experience with this desktop environment. Also, Frameworks is at 5.72.0, Plasma at 5.19.3, and KDE Applications at 20.04.3.

Many packages have been updated e.g. Guile 2.2.6, Mesa 20.1.3, NetworkManager 1.26.0, Perl 5.30.3. All this with Linux kernel 5.7.8 as engine and QT 5.15.0. Also, The Midna theme used for KaOS has been redone for 2020.

Conclusion

KaOS is one of those rather special Linux distributions. It has earned its reputation and is perhaps the best for enjoying a full-blown Plasma KDE.

If you are interested you can download it from this link. You can also check the release notes for more information.

However, for all the gloss and polish, KDE Plasma is a resource-heavy desktop environment. If your system is low on hardware resource, then running other desktop environments is strongly recommended.

Over time, you may feel like your KDE Plasma is becoming slower and slower. If you’re being annoyed of a slow KDE Plasma environment, consider the following tips for refreshing the environment and enjoy the full potential of your system!

Note that all the following steps were performed on my Kubuntu 18.10 system. However, these tricks should work perfectly on any other Linux distros using KDE Plasma.

KDE Plasma speed-up hacks

• Update the KDE Plasma

KDE Plasma is a fine and well-maintained project. It gets updated and tweaked on a regular basis for proving the freshest feel and features to the users. If you’ve been using your system for a quite long time, it’s highly likely that your KDE Plasma is out-of-date.

From the menu, type “Discover” (without quotes) –

Discover is the default software center of KDE Plasma desktop.

From the bottom-left corner, select the “Updates” tab.

Hit “Check for Updates” >> update all the software possible. In my case, all my software are up-to-date.

• Desktop effects

In the KDE Plasma, there are numerous desktop effects. All the effects force a heavy load on the hardware. If your system is low on hardware resource, turning down the effects is a good place to speed things up.

From the menu, type “effects” >> select “Desktop effects”.

As you can see, there are tons of effects ongoing in my system. In your case, the selections may be different.

Once you’re done, hit “Apply” >> “OK”.

• Remove Akonadi

Akonadi is a robust service of KDE Plasma that allows apps to directly interact data with the KDE Plasma. It doesn’t make a noticeable difference in the case of high-end computer systems but it can definitely hurt low-end machines.

Run the following command(s) according to your Linux distro –

• Ubuntu

sudo apt remove akonadi --purge

• Debian

sudo apt-get remove akonadi --purge

• Fedora

sudo dnf remove akonadi

• OpenSUSE

sudo zypper remove akonadi

• Arch Linux

sudo pacman -Rsc akonadi

Then, restart your computer.

• Changing window managers

By default, KDE uses its own window manager. The window manager is greatly responsible for putting all the loads on your CPU and GPU. In that case, you should switch to a lighter one like Openbox. Openbox is a great one that’s easily compatible with KDE Plasma without any tweaking!

Run the following command(s) according to your Linux distro –

• Ubuntu

sudo apt install openbox openbox-kde-session

• Debian

sudo apt-get install openbox openbox-kde-session

• Fedora

sudo dnf install openbox-kde

• OpenSUSE

sudo zypper install openbox-kde

• Arch Linux

sudo pacman -S openbox

Then, restart your system and login using the KDE/Openbox session.

Voila! Your system should perform like brand new again!

KDE Plasma is also full of powerful and useful widgets. The huge collection offers even more customizability and other features. However, for new users, this huge collection is nothing like a big mess. It only makes it harder for them to find out the proper one. That’s why there are some of the best and essential ones to try out.

Note that you can customize as much as you want in the default setup to make it suitable for your needs as well.

• KDE Connect

This powerful widget allows you keep the track of all your things in one place. For example, you can see your smartphone notifications, battery warning, and all other kinds of stuff in just one place.

This widget enables KDE to stand out of all other choices. KDE Connect is available on Android. For KDE fans, this is a must-have.

Learn more how to install KDE Connect. After installing, you have to install KDE Connect Indicator. Get KDE Connect on Android.

• Win7 Volume Mixer

If anyone has ever used Windows 7, you’ve definitely noticed the volume section. It allowed you to control the sound of different apps differently. This feature isn’t commonly available on Linux desktops because all the sounds are played as one sound. You change the volume altogether, not separately.

Thanks to this superb widget, you can now get the feeling of Windows 7 volume mixer back on your KDE Plasma. Check out Win7 Volume Mixer!

• KSmoothDock

If you’re a fan of the elementary OS or the dock system, KSmoothDock is your most suitable choice. KDE offers this great widget to give you the best feel of macOS. It’s extremely customizable and simple to understand. Whenever you hover your cursor on the apps, they even zoom, just like macOS.

Despite acting like macOS, this widget also bears the inheritance of Linux apps and mimic the panel functionality. This is also refreshing to switch from the traditional to the new look. Get KSmoothDock now!

• Simple Menu

Minimalistic themes are the most powerful ones in the present days. They offer simpler interface and workflow, thus allowing more focus on the work. Moreover, simplistic & minimalistic designs consume less hardware resource, leaving plenty of room for other tasks.

If you’re a fan of the classic system, you will obviously love Simple Menu. This widget is very simplistic app launcher for the Plasma desktop.

I personally love this widget for its usability. Just try it out, you won’t regret. Get Simple Menu today!
