Tilix terminal emulator released version 1.9.6 few days ago. Here’s how to install it in Ubuntu 22.04, Ubuntu 23.04, and Ubuntu 23.10.
Tilix is a tiling terminal emulator, which uses the VTE GTK+ 3 widget for various features, such as split horizontally or vertically, transparent background, background images, quake mode support, custom hyperlinks, experimental trigger and badge support.
The development of Tilix is moving slowly now due to lack of maintainers. The new 1.9.6 is released more than 20 months after the last stable. And, it only includes minor new features and bug-fixes:
Add close button to search box.
Replace variables in custom link commands
Follow system color-scheme for default theme-variant
Add compatibility with Nautilus 43
Avoid shell injection in open-tilix plugin
Fix GLib critical warnings on startup
Update to GtkD 3.10.0
Tilix search box has close button.
How to Install Tilix 1.9.6 in Ubuntu 22.04, Ubuntu 23.10
The new release provides prebuild package for Linux, which is available to download at the link below:
It’s ‘tilix-1.9.6_x86_64-linux-gnu.tar.gz‘ for 64-bit modern PC and laptop. Just download the package, extract, and run the executable to launch the terminal emulator.
Ubuntu PPA
The official tarball does NOT include run-time libraries. You have to manually figure out “error while loading shared libraries …” errors.
To make the life easy, I’ve upload the new packages into this unofficial PPA, build against the rules from Debian Unstable. So far, it supports Ubuntu 22.04, Ubuntu 23.04, Ubuntu 23.10, on both x86_64 and AArch64(arm64).
1. First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:ubuntuhandbook1/tilix
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Linux Mint 21 users need to refresh system package cache manually, by either running the command below or using “Refresh” button in Update Manager:
sudo apt update
3. Finally, either run command to install the terminal emulator:
sudo apt install tilix
Or, update it through Software Updater (Update Manager) utility.
NOTE: Upgrading from v1.9.5 may cause following error pop-up at launch, but I don’t know how to correct the issue.
Thanks to @oswald_c, you may fix the issue by enabling ‘Run command as a login shell’ to enable it‘ option under default profile of “Preferences” dialog. See the screenshot below:
Uninstall Tilix
To downgrade Tilix to stock version in your system repository, open terminal (Ctrl+Alt+T) and run command to purge the PPA:

Have multiple monitors connected to your Ubuntu 22.04 machine? There’s now an indicator to dim all or individual monitor screen brightness with sliders.
You can dim external monitor brightness with either physical buttons or ddcutil utility. However, an indicator applet in system tray can be more effective, and here’s one for Ubuntu 22.04 with default GNOME 42.
It’s a Gnome Shell extension, that adds a light bulb to top-right corner in panel. By clicking on it, will show you the slider to dim all the connected monitors, as well as individual sliders to dim certain screens.
And, by moving the slider to far right will make the screen totally dark, just like being turned off.
Besides dimming monitor screens, it can also change the colors with RGB sliders, which also can apply to either all or individual monitors.
As my laptop’s external HDMI port is broken, I can’t try out the multi-monitor support. But, the dimming and RGB color (need to at least move dim slider a bit to right) functions are working very well in my case in Ubuntu 22.04 Desktop PC.
My test without multi-monitors
How to Install the Dimming Control Indicator
First, launch Ubuntu Software, then search for and install “Extension Manager” app.

NVIDIA announced 545.29.02 graphics driver for Linux yesterday, as a new release series for its New Feature Branch Version.
For Ubuntu 22.04 + and Fedora Workstation with default GNOME on Wayland, as well as KDE on Wayland, the new driver adds support for the CTM, DEGAMMA_LUT, and GAMMA_LUT DRM-KMS CRTC properties, which, finally make the ‘Night Light’ and ‘Night Color’ feature work for NVIDIA users.
Night Light finally works on Wayland with NVIDIA driver
For desktop GPUs, the release adds initial experimental support for runtime D3 (RTD3) power saving mode. When all the PCI functions are idle, and all required conditions are satisfied, your GPU will go to the lowest power state resulting into maximum power savings.
The new driver also added experimental support for framebuffer consoles. On kernels with implement features, nvidia-drm will install a framebuffer console when loaded with both modeset=1 and fbdev=1 kernel parameters. Though, when an nvidia-drm framebuffer console is enabled, unloading nvidia-drm will cause the screen to turn off.
Other changes in NVIDIA 545.29.02 include:
Experimental HDMI 10 bits per component support
Support for virtual reality displays
CERTIFIED-quality support for GeForce and Workstation GPUs to open kernelmodules.

How to Install Linux Kernel 6.6
The Ubuntu Mainline Kernel PPA somehow stuck at v6.6 RC5. So, there’s no proper way to get the Linux Kernel 6.6 at the moment of writing besides building from the source code.
Though, you can keep an eye on the third-party trustworthy Zabbly repository, which should update for the 6.6 Kernel in next few days.
This simple tutorial shows how to display live earth as desktop wallpaper in Ubuntu 22.04 and Ubuntu 24.04.
Ubuntu has Wallch wallpaper changer in system repository, which has option to show live earth as wallpaper. However, the app is no longer updated and the feature is broken for all current Ubuntu releases.
If you’re interested in viewing high-resolution 3d real-time image of the earth in your desktop, then there’s another free open-source tool can do the job.
It’s liewa (Live Earth Wallpapers), that supports all known geostationary satellites for the high resolution sentinel images, Nasa Solar Dynamics Observatory images and NASA astronomy picture of the day (Apod)!
By default, it uses GEOS-16 satellite for the earth image, that display a small earth in center of your screen. Though, the app has setting options to add or edit satellites.
Add, configure satellites
So, you can have more than one real-time images of the earth from different satellites displayed on your screen at the same time, in different size, with either natural color or geocolor.
How to Install Live Earth Wallpapers (Liewa)
The tool provides .deb package for downloading in its Github releases page:
After downloaded the .deb package, right-click on ‘Downloads’ folder and select “Open in Terminal”. Finally, run command to install it in pop-up terminal window:
sudo apt install ./liewa.deb
Finally, launch it from either start/applications menu or the overview screen depends on your desktop environment.
When the app window opens, configure canvas size, satellites, etc in first tab, then click on “Create New Scheduler” in Scheduler tab should start the live earth wallpaper.
Though, it takes quite a few seconds to apply, waiting for automatically start the service. If you can’t wait, try to open terminal (Ctrl+Alt+T) and run command to manually start the service:
systemctl status --user liewa
Uninstall:
You can stop the live earth wallpaper by clicking on “Delete Scheduler” button in app window, then set another wallpaper via ‘Background’ settings.
To remove the software, simply open terminal (Ctrl+Alt+T) and run command:
