!Xubuntu16.04 on X280
X280にインストールしていた Ubuntu 18.04 (MATE) を消して,
Xubuntu 16.04をインストール.
手元の環境がxfce4なのは久しぶり.
いい感じのショートカットキー設定ができて,いい感じ.


インストールメモ
* 日本語入力はfcitx-mozc.IMEのオン/オフはAlt+`に.
* メニュー表示は,xfce4-popup-whiskermenuという命令.SuperLに割当て.
* remminaはaptでそのまま入れるとゲートウェイ対応してないので最新版を
 sudo add-apt-repository ppa:remmina-ppa-team/remmina-next
* chrome,mono,skype,slack,dropbxo,Java8なんかはsource.list.dを追加してインストール.
* lid closeがsuspendじゃなくてswitch off displayだったのでsuspendに.

!ベンチマーク @ X280

Streamだと,

 STREAM version $Revision: 5.10 $
 -------------------------------------------------------------
 This system uses 8 bytes per array element.
 -------------------------------------------------------------
 Array size = 100000000 (elements), Offset = 0 (elements)
 Memory per array = 762.9 MiB (= 0.7 GiB).
 Total memory required = 2288.8 MiB (= 2.2 GiB).
 Each kernel will be executed 10 times.
  The *best* time for each kernel (excluding the first iteration)
  will be used to compute the reported bandwidth.
 -------------------------------------------------------------
 Number of Threads requested = 1
 Number of Threads counted = 1
 -------------------------------------------------------------
 Your clock granularity/precision appears to be 1 microseconds.
 Each test below will take on the order of 152873 microseconds.
    (= 152873 clock ticks)
 Increase the size of the arrays if this shows that
 you are not getting at least 20 clock ticks per test.
 -------------------------------------------------------------
 WARNING -- The above is only a rough guideline.
 For best results, please be sure you know the
 precision of your system timer.
