要變更設定,滑鼠按「開始鈕」右鍵,選 [面板]→[面板偏好設定]→[視窗按鈕],如下圖:
可以自定選項。例如 [排序] 改成 [無,允許拖放],即可按自己的順序,拖拉己開啟的 app 來排序。
$ sudo apt update一定要安裝的中文輸入架構,我慣用 fcitx
$sudo apt install fcitx fcitx-ui-classic fcitx-config-gtk安裝倉頡三、倉頡五、新酷音(就是注意輸入法)
$ sudo apt install fcitx-table-cangjie3 $ sudo apt install fcitx-table-cangjie5 $ sudo apt install fcitx-chewing
$ alias ll='ls -alh'
$ sudo apt-get install fonts-moe-standard-kai fonts-cwtex-yen改變桌面大小
$ lxrandr
$ http://ppa.launchpad.net/nemh/systemback/ubuntu/pool/main/s/systemback/
安裝系統備份 systembackNetworkManager-wait-online.service, 可以試著用「disable」指令把它取消:
sudo systemctl disable NetworkManager-wait-online.service

sudo hdparm -Tt /dev/sda
可以測 sda 硬碟速度。
/dev/sda:
Timing cached reads: 7406 MB in 2.00 seconds = 3704.50 MB/sec
Timing buffered disk reads: 374 MB in 3.01 seconds = 124.27 MB/sec
我的 128G SSD碟,測試結果:
#sudo hdparm -Tt /dev/sdb
/dev/sdb:
Timing cached reads: 7466 MB in 2.00 seconds = 3734.90 MB/sec
Timing buffered disk reads: 800 MB in 3.00 seconds = 266.45 MB/sec
