r/Crostini

Hey everyone,

I finally made the jump to ChromeOS’s next-gen Linux environment, Baguette.

To do this, I completely deleted Linux from my settings and turned it back on. The newly created VM now comes default with a pure, container-less VM architecture running Debian 13 (Trixie) right out of the box. An update from Bookworm is currently in the works for the future.

The biggest change you will notice immediately is how much RAM is freed up:

• No LXD Container: The old Crostini setup wasted roughly 800 MB to 1.1 GB of RAM just idling because of heavy background container daemons. Baguette sits at just 200 MB to 300 MB at idle. That instantly hands over 700 MB+ of RAM back to your Chrome browser tabs. If you are running an 8 GB Chromebook definitely consider the change.
• Smart Resource Balancing: It uses modern cgroups v2 and dynamic memory ballooning. It shares RAM gracefully with Chrome OS and throttles background tasks before your system panics or crashes from an Out-of-Memory error.
• Direct KVM Access: Since the middleman container layer is gone, you can run nested virtualization smoothly. Running Docker, Podman, and Kubernetes clusters works natively without permission hacks.
• Zero-Lag GPU Sharing: UI artifacting, graphical flickering, and window glitches are completely gone. Flatpaks and modern GUI apps render flawlessly.
• Faster Disk I/O: It uses a single, direct virtual disk mapping. Package installations (npm install, apt, etc.) and code compiling are significantly faster.
• Better System Sleep: Closing the laptop lid no longer causes the Linux network routing to freeze or crash.

The Bad:

• No UI App Installers: You can no longer double-click a .deb file in the ChromeOS Files app to install software. You have to use the terminal now (though this feature was being phased out regardless of the container-less change).
• No Multi-Containers: The #crostini-multi-container flag is completely deprecated.

wl-copy no longer works on Chromebook. Any replacements? xclip doesn't work either.

I am using 3 containers. I have been aware that multi-container support is going away.

I have started receiving the following message upon starting up any linux container.

My preparations:

• I have moved my files and applications from my secondary containers into my penguin container

My questions

1. is there anything else I should be doing to prepare? (I have no ability to remove the abandoned containers through the settings, because container management was removed from settings)
2. will my penguin container remain intact?
3. when will this change occur?
