Canonical has introduced that it is going to be enabling zswap, swap-based reminiscence compression, by default for its Raspberry Pi Ubuntu builds to deliver the total desktop expertise to the Raspberry Pi 4 Mannequin B 2GB — and has provided a information for setting it up your self if you cannot look forward to the following launch.
Canonical’s curiosity within the Raspberry Pi household of single-board computer systems when it launched Ubuntu 19.10 “Eoan Ermine” with official photos for the Raspberry Pi 2, 3, and 4, after pledging the platform would obtain “full official assist.” These server-centric photos had been adopted by Ubuntu 20.10 “Groovy Gorilla,” which provided, for the primary time, a desktop picture with full graphical person interface as commonplace.
The catch: “On a Raspberry Pi 4 (with 4GB or 8GB RAM) you are able to do every little thing the common desktop person would anticipate,” Canonical’s Rhys Davies stated of the discharge, tacitly admitting that the 1GB and 2GB fashions would not work fairly so nicely.

Now, Canonical is trying to prolong official assist to the 2GB mannequin — by enabling zswap, a method of enhancing efficiency by creating high-priority swap units which compress currently-unused reminiscence contents to save lots of area with out the prolonged delays and doubtlessly extreme write operations related to a swap file or partition on microSD.
“Considered one of our targets for the upcoming Ubuntu 22.04 LTS launch is to decrease [the] barrier to entry,” Canonical’s Oliver Smith explains. “This implies concentrating on a viable Desktop expertise on Raspberry Pi 4 2GB fashions. When Ubuntu 22.04 releases in April, these optimizations can be included by default for all Raspberry Pi 4 units, together with the 400!”
These working earlier releases, in the meantime, can observe the information on the Ubuntu weblog to allow zswap now — and, if desired, change its defaults out for these which can arrive in Ubuntu 22.04, together with the usage of LZ4 compression to spice up efficiency nonetheless additional.
