Canonical's Ubuntu Desktop Team is adjusting Ubuntu 26.10's OOM behavior to ensure critical desktop services are less likely to be killed under memory pressure, improving system stability.
Ubuntu is changing how it handles running out of memory to keep important parts of the computer running so you can use it.

{"heading":"Critical Services Protection","subheading":"Ensuring Critical Services Are Not Terminated","content":["Canonical's Ubuntu Desktop Team is implementing changes to Ubuntu 26.10's OOM policy to protect critical desktop services from being terminated under memory pressure.","The new policy lowers the OOM score for critical desktop services, making them less likely to be selected by the kernel OOM killer.","Applications and background services will keep a higher default score, ensuring they are terminated first when encountering significant memory pressure."]}
Key points
- Ubuntu 26.10 is changing its OOM policy to protect critical desktop services
- Critical services will have a lower OOM score to prevent them from being terminated
- Background services will have a higher score to ensure they are terminated first
This change should help keep the Ubuntu desktop running smoothly even when the computer runs low on memory.
While this change should improve stability, the Ubuntu desktop may still need to terminate some applications to free up memory.
