Frequently asked questions
Why do I need a dedicated screen capture app on Ubuntu?
Ubuntu's default GNOME screenshot tool can capture basic areas, but it lacks annotation tools, arrow markers, blur redaction, and text extraction. To mark up screenshots, you must open an external editor like GIMP. Screention lets you capture, draw arrows, redact sensitive details, and copy directly to your clipboard in one fluid step.
Does Screention work on Ubuntu 24.04 and 22.04 LTS?
Yes. Screention is tested and fully supported on Ubuntu 24.04 LTS (Noble Numbat) and Ubuntu 22.04 LTS (Jammy Jellyfish). It works with both the default GNOME Wayland desktop and X11 sessions.
How do I install Screention on Ubuntu?
You can install Screention with our 1-line terminal installer: curl -fsSL https://screention.gkernel.com/install.sh | bash, or download the official .deb package and install it via sudo dpkg -i.
Can I replace the default Ubuntu PrintScreen shortcut?
Yes. In Ubuntu Settings → Keyboard → Keyboard Shortcuts → Custom Shortcuts, you can bind Screention to the PrintScreen key or any shortcut combination you prefer.
How does Wayland capture work on Ubuntu?
Screention communicates with the native XDG Desktop Portal implemented in GNOME Shell. On first capture, Ubuntu prompts you for screen permission, and subsequent captures trigger instantaneously.
