I’ve been using 16.04 64bit for more than two years on my Intel i3, 3.6GB memory laptop with traditional interface (Application, Places) and the idle memory usage was 500MB. But now after fresh install of 18.04, I’m seeing the idle memory usage has been doubled to 1GB. Also other noticeable change was fcitx instead of ibus as the default input method which is consuming more memory.
Is there a way to considerably reduce memory usage in 18.04 64bit like it was in 16.04 64bit?
