在ubuntu中安裝好spyder後， 開啟spyder發現無法輸入。 
在開啟spyder的終端視窗，有如下提示:

QXcbConnection: Failed to initialize XRandr 
Qt: XKEYBOARD extension not present on the X server. 
Qt: Could not determine keyboard configuration data from X server, will use hard-coded keymap configuration. 
Qt: Failed to compile a keymap
 
! 
Current XKB configuration data search paths are: 
/home/xxx/anaconda3/lib 
Use QT_XKB_CONFIG_ROOT environmental variable to provide an additional search path, add ‘:’ as separator to provide several search paths and/or make sure that XKB configuration data directory contains recent enough contents, to update please see http://
 
cgit.freedesktop.org/xkeyboard-config/ .

解決方法

到自己的home目錄下（~），開啟資源配置檔案：

cd ~
vim .bashrc

然後在檔案末尾新增兩行：

export XKB_DEFAULT_RULES=base
export QT_XKB_CONFIG_ROOT="/usr/share/X11/xkb:$QT_XKB_CONFIG_ROOT"

然後重新載入環境:

source .bashrc

開啟spyder 問題解決
