How to Install OBS Studio 30.0 in Ubuntu
The release page (see the link above) provides Windows .exe, Mac OS .dmg, and Ubuntu .deb packages for downloading under ‘Assets’ section.
For Ubuntu and Linux Mint, there’s also an official PPA available to make it easy to keep the software up-to-date.
The PPA supports the new release for Ubuntu 22.04, Ubuntu 23.04, Ubuntu 23.10, and their based systems. While, Ubuntu 20.04 does not longer supported due to FFmpeg version mis-match.
1. Firstly, press Ctrl+Alt+T on keyboard to open a terminal window. When it opens, run command to add the PPA:
sudo add-apt-repository ppa:obsproject/obs-studio
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Then, either use Software Updater to update the software package (if an old version was installed).
Or, use apt command to install/upgrade the software package:
sudo apt install obs-studio
NOTE: Linux Mint may need to run sudo apt update first to update package cache.
Once installed, search for and launch OBS Studio from ‘Activities’ overview or start menu depends on your desktop environment and enjoy!
NOTE: OBS Studio in Ubuntu 22.04 and higher with Wayland, looks kinda borderless, due to Qt theming issue. If you prefer the classic header-bar and window border, see this tutorial to enable xcb plugin
Uninstall OBS Studio
To downgrade the software to the stock version that your system repository provides, run command:
PTBatcherGUI can now also queue user defined assistant and user defined output sequences.
PTBatcherGUI: Added option to generate panorama sequences from an existing pto template.
Assistant: Added option to select different output options like projection, FOV or canvas size depending on different variables (e.g. image count, field of view, lens type).
Allow building with epoxy instead of GLEW for OpenGL pointer management.
Several improvements to crop tool (outside crop, aspect ratio, …).
For all current Ubuntu releases, including Ubuntu 18.04, Ubuntu 20.04, Ubuntu 22.04, Ubuntu 23.10, and their based systems, I’ve made the unofficial package into this PPA repository, not only for x86_64 but also 32-bit/64-bit ARM support!
I also sync the packages into the apps PPA, use either one as you prefer.
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/hugin
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Update system package cache for Ubuntu 18.04 and Linux Mint, though it’s done automatically while adding PPA in Ubuntu 20.04+:
sudo apt update
3. Finally, either run the command below in terminal to install the panorama photo stitcher:
sudo apt install hugin
Or, upgrade the software (if an old version was installed) via Software Updater (Update Manager) app:
Uninstall hugin:
To remove the software package, simply run command:
sudo apt remove --autoremove hugin hugin-data
And, remove the PPA either by running command in terminal:
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:
GIMP image editor now is at version 3.0.x, and I’ve made a PPA for those who prefer the native .deb package format.
If somehow you need to install the old GIMP 2.10.38 in Ubuntu, then this tutorial may help!
First of all, GIMP 2.10.38 includes Windows Ink drivers support for better tablets support on Windows. It also backports some small features from GTK3 to GTK2, with some improvements for Windows users. They include:
Use native Windows API for converting keystrokes to characters,
Fix keyboard input when using IMEs,
Fix mouse events in presence of transparent windows on the desktop,
Win32 IME Fixes, and more.
Besides the improvements for Windows users, the release also includes various bug-fixes, including that GIMP crashes every time on exit in my case in Ubuntu 24.04. See release note for more about GIMP 2.10.38.
(Old content for GIMP 2.10.36) The new release also has some new features. They include Adobe Swatch Exchange (ASE) and Adobe Color Book (ACB) palettes support.
Gradient Tool now has an “FG to Transparent (Hardedge)” option, to generate a gradient from the foreground color to transparency, with hard-edge transitions between the 2 colors. Which, as well includes a “Repeat” option to alternate repetitive colored shapes.
As time goes on, the old commit will be removed! At that time, this command will no longer work.

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.
Support for PRIME render offload to Vulkan Wayland WSI
Support for HDR signaling
Add support to NVIDIA VDPAU driver for running in Xwayland
Support EGL_ANDROID_native_fence_sync EGL extension.

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.
