please reply that.Thank You

Ok...now how about telling us WHEN you got those messages, what you were trying to do, version/distro of Linux, and maybe we can help. All we've got so far is a list of error messages, with nothing to relate them to.

Have you checked disk space, as the error suggested? What desktop are you trying to launch? Does this happen with any other users? Can you log in as failsafe??

And please post your /etc/profile and /etc/bashshrc with line numbers. It's easier to read if you put it in code tags (that's a link to instructions or you may prefer to use "Advanced Edit" mode which has a # button for code tags). One way to show line numbers is to open the file with vim, enter :set number then copy-and-paste. You can get out of vim by pressing escape followed by :q!

i tried to log in my linux computer in VMware,after restarting it.but i couldn't do that.
etc/profile -line 51
etc/bashshrc -line 8

And you still haven't answered any of the questions we've asked. How do you expect any of us to help you?
