登录之后无法进入桌面，一直停留在紫色的界面，startx有如下的信息：
Using system config directory "/usr/share/x11/xorg/.conf.d"
The XKEYBOARD keymap compiler (xkbcomp) report:
>Error: can't find file "default" for symbols include
> Excting
> Abandoning symbols file "default"
Errors from xkbcomp are not fatal to the X server
(II) AIGLX:Suspending AIGLX client for VT switch

有人遇到过这种情况吗，好像是在更新了软件之后出现的这种情况

this problem was caused by someone or something modifying my copy of /usr/share/X11/xkb/rules/evdev. Reinstalling the xkb-data package fixed it.
