我从root登陆后，请问从终端窗口将root切换至我的另一普通用户如kkk[已解决]

adsl9999

我知道从kkk到root用su命令
反过来？谢谢！

su kkk

su - 用户名           --切换到另一用户，且夹在该用户的环境配置
su 用户名            --切换到另一用户，但不加在该用户的环境配置
所以，一般切换用户，如果不退出当前用户，可以直接用su - 用户名方式更好些

请问高手，root下我的gmplayer播放视频文件时图像倒置.

原来都正常，root下gmplayer播放视频文件时，我点击调节图像比例16:9后图像倒置，再也改不过来了，但root下mplayer无此问题，非root下(ma)gmplayer无此问题.
