登陆Ubuntu的时候出现如下问题,搜了下,没发现和我的一样的,特来求助
问题如下:
You session only lasted less than 10 seconds.If you have not logged out yourself,this could mean that there is some installation problem problem or that you may be out of diskspace.Try logging in with ont of the failsafe sessions to see if you can fix this problem.
点开下面的详细消息,如下:
/etc/gdm/Xsession:Beginning session setup
export:3: bad variable name
不过用failsafe session可以登陆进去,求助啊.. 我试过把我在Windows下虚拟机中的这个文件拷过去,可是一样没用
下面是我的/etc/gdm/Xsession这个文件的全部内容:
#!/bin/sh
#
# This is SORT OF LIKE an X session, but not quite. You get a command as the
# first argument (it could be multiple words, so run it with "eval"). As a
# special case, the command can be:
# failsafe - Run an xterm only
# default - Run the appropriate Xclients startup (see the code below)
# custom - Run ~/.xsession and if that's not available run 'default'
#
# (Note that other arguments could also follow, but only the command one is
# right now relevant and supported)
#
# The output is ALREADY redirected to .xsession-errors in GDM. This way
# .xsession-errors actually gets more output such as if the PreSession script
# is failing. This also prevents DoS attacks if some app in the users session
# can be prodded to dump lots of stuff on the stdout/stderr. We wish to be
# robust don't we? In case you wish to use an existing script for other DM's,
# you can just not redirect when GDMSESSION is set. GDMSESSION will always
# be set from gdm.
#
# Also note that this is not run as a login shell, this is just executed.
#
