Xlib: connection to ":0.0" refused by server
Xlib: No protocol specified
Error: Can't open display: :0.0
这是老问题了,不过这次对我来说却有些不同。想在自己的本本Ubuntu上安装Oracle 10,结果新增加的用户Oracle不能运行X程序。
查了查资料和手册,以日常工作用的那个用户登录,在shell中运行
xhost local:Oracle
non-network local connections being added to access control list
然后Oracle身份就可以运行X程序了。
man xhost中有这样一段
A complete name has the syntax ‘‘family:name’’ where the families are as follows:
inet Internet host (IPv4)
inet6 Internet host (IPv6)
dnet DECnet host
nis Secure RPC network name
krb Kerberos V5 principal
local contains only one name, the empty string
si Server Interpreted
其中local那个是用来解决同一台机器的不同用户访问X的问题的。
