Running Ubuntu 22.04 with the default Wayland session? You can switch your web browser’s backend to get even faster and smoother experience.

Firefox, Google Chrome and Chromium based web browsers do have native Wayland support, but they still use X11 as backend in Ubuntu desktop.

Since Ubuntu 22.04 by default logs into Wayland session, user can also change the web browser’s backend to get faster and smoother browsing experiences. I didn’t run any benchmark. But after switching to Wayland, my browser now has:

  • obviously better touchpad scrolling
  • 2-finger spread/pinch gestures to zoom in/out

Enable Wayland for Chrome/Chromium

For Google Chrome, Chromium and their based web browsers, e.g., Edge, Vivaldi, just type chrome://flags/ in address bar and hit Enter.

When the page opens, search for Preferred Ozone platform and use the dropdown menu to set it value to “Wayland“. Finally, click “Relaunch” button to apply change by restarting the web browser.

Chrome enable wayland

Native Wayland for Firefox

For firefox web browser, user need to edit the “/etc/environment” config file.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to open the file via gedit text editor:

sudo gedit /etc/environment

Replace gedit with your favorite text editor, such as gnome-text-editor for next Ubuntu 22.10 & Fedora.

When the file opens in text editor, just add a new line:

MOZ_ENABLE_WAYLAND=1

As the screenshot shows, you can also add more rules into this config file:

  • MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 – to fix a slightly laggy, slightly sloppy mouse response issue.
  • CLUTTER_PAINT=disable-dynamic-max-render-time to get a smoother frame rate.

After saving the changes in the config file, restart your computer to take effect!

This simple tutorial shows how to install the latest LXQt desktop 1.1.0 in (L)Ubuntu 22.04 via its official PPA.

The light LXQt desktop environment has reached version 1.1.0 for a few months, which LUbuntu 22.04 ships the 0.17 version by default.

Changes since LXQt 0.17 to 1.1.0 include:

  • Depend on QT 5.15 LTS.
  • Option to make desktop items sticky by default
  • Add ‘do-not-disturb’ mode.
  • Add “Custom Command” plugin
  • New wallpapers and themes.
  • New component xdg-desktop-portal-lxqt for non-Qt apps to use LXQt file dialog.
  • See more at the releases page.

Install LXQt 1.1.0 via PPA:

LUbuntu announced the official backports PPA few months ago, to provide the latest LXQt desktop stack.

1. Purge third-party PPA (if any)

For those who are using this unofficial PPA for the latest LXQt packages, LUbuntu team recommends to remove it first.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the ppa-purge tool:

sudo apt install ppa-purge

Type user password (no asterisk feedback) for sudo prompt and hit Enter to continue.

Next, use the tool to purge unofficial PPA which also downgrade all installed packages:

sudo ppa-purge ppa:severusseptimius/lxqt

2. Add LUbuntu backports PPA

Then, run the command below in terminal to add the official PPA instead:

sudo add-apt-repository ppa:lubuntu-dev/backports

3. Update LXQt Desktop:

Finally, use the command below to update LXQt to v1.1.0:

sudo apt full-upgrade

NOTE: apt full-upgrade is required rather than apt upgrade, or some core libraries will be kept back.

For non-LUbuntu but Ubuntu 22.04 based systems, use the command below to install LXQt 1.1.0:

sudo apt install lubuntu-desktop

In case you want to restore your system later, it’s better to written down what packages it’s going to install via terminal output

Uninstall LXQt 1.1.0 in LUbuntu 22.04

To restore your LUbuntu desktop, run the command below in terminal to install ppa-purge and use the tool to purge the PPA repository:

sudo apt install ppa-purge && sudo ppa-purge ppa:lubuntu-dev/backports

Finally, restart your system.

For KUbuntu 22.04 users, the KDE Plasma 5.25 desktop is available to install via official PPA repository!

New Features in KDE Plasma 5.25:

Plasma 5.25 was released a few months ago, with great user experience improvements for Laptop and Tablet users.

It introduced the multi-touch gestures support for PC with a touchpad device:

  • 3-finger swipe any direction to switch workspace.
  • 4-finger pinch to open overview.
  • 4-finger swipe down to open present.
  • And 4-finger swipe up to activate desktop grid.

By detaching the screen or rotating it 360° will enable touch mode automatically for laptops that support it.

User can also swipe on touch-screen from the screen edge to open Overview, Desktop Grid, Present Windows, and Show Desktop.

Other exciting features includ:

  • Automatic accent color that follow background wallpaper.

How to Install KDE Plasma 5.25 via PPA

The new desktop packages have been made into testing repository for a month. And, I was waiting for the updates to be made into the stable backports PPA until I see the new extra PPA.

The packaging team backported the Plasma 5.25 packages into KUbuntu Backports Extra PPA for (K)Ubuntu PPA.

1. First, either press Ctrl+Alt+T on keyboard or search for and open terminal (koncole) from start menu. When it opens, run the command below to add the PPA:

sudo add-apt-repository ppa:kubuntu-ppa/backports-extra

Type user password when it asks (no asterisk feedback) and hit Enter to continue

2. While adding the PPA, it should refresh the package cache automatically. In case it did not, run the command below to do it manually:

sudo apt update

3. Finally, update your desktop environment in KUbuntu 22.04 by running command:

sudo apt full-upgrade

NOTE: It must be apt full-upgrade rather than apt upgrade, or Plasma desktop 5.25 will be kept back due to dependency library change.

If you’re going to install Plasma 5.25 on non-KDE Ubuntu edition, use command:

sudo apt install kubuntu-desktop

It’s BETTER to make a backup of what it’s going to install via terminal output, in case you want to restore you desktop to previous status.

Uninstall Plasma 5.25:

To remove the new desktop environment and revert back KUbuntu 22.04 to previous status, run command to install ppa-purge:

sudo apt install ppa-purge

Then use the tool to purge that PPA, which also downgrade all install packages to the stock versions:

sudo ppa-purge ppa:kubuntu-ppa/backports-extra

This simple tutorial shows how to set custom names for your desktop workspaces, and replace “Activities” in the top-left with the current workspace name you specified.

Today’s desktop operating systems mostly have multiple desktops to group app windows in different screen. These virtual desktops in GNOME (default desktop environment in Ubuntu/Fedora Workstation) are called workspaces. And, each workspace can have its own name.

Step 1: Set custom names for your workspaces

1. First, search for and install “Dconf Editor” if you don’t have it from Ubuntu Software (or GNOME Software).

2. Next, search for and open the Dconf Editor tool from ‘Activities’ overview screen.

When it opens, navigate to “org/gnome/desktop/vm/preferences“. Scroll down and click on “workspace-names” to get into the setting page.

Finally, turn off the default value, and type your desired named in ‘custom value’ box.

NOTE: GNOME by default has 2 workspaces. It adds/removes workspaces automatically to keep only one extra empty workspace. To set fixed number of workspaces, open “Settings” and navigate to “Multi-tasking > Workspaces”

For those familiar with Linux commands, this can be done simply by running the command below in terminal:

gsettings set org.gnome.desktop.wm.preferences workspace-names "['name1', 'name2', 'name3', 'name4']"

Step 2: Replace “Activities” with current workspace name

By replacing “Activities”, you can take a glance at top-left to make sure which workspace you’re working on. Though the name changes, it’s still working like before. By clicking on it will open the overview screen.

1.) First, search for and install “Extension Manager” from Ubuntu Software.

Install Extension Manager in Ubuntu 22.04

2.) Then, search for and launch the tool you just installed from overview screen:

3.) Finally, navigate to “Browse” tab, search for and install the “Activities Workspace Name” extension.

For Fedora 36 user, just go to the extension web page and use the ON/OFF switch to install it:

NOTE: If you set workspace names after installed the extension, restart GNOME Shell it required to make it work. To do so, press Alt+F2, type ‘r’ and hit Enter on Xorg session, or log out and back in on default Wayland.
