I have a administrator account in which if i open the terminal, it like shows up for a fraction of a second and then vanishes. i tried with guest and other user accounts (created from this one). I was able to open terminal. What is the problem? How to open terminal properly from my main account? I am not even able to do anything on the screen that comes on Ctrl+Alt+F1. Over there, i put my login id and then password then suddenly some text comes there and the next second, vanishes. Asking me to login again

sorry , updated my answer. – Raja Nov 16 '13 at 17:00
I'd suggest logging in to a TTY (ctrl+alt+F1) then running DISPLAY=:0 gnome-terminal. See if there are any error messages. – minerz029 Nov 16 '13 at 21:04

Press CTRL+ALT+F1 and login there with your name and password and then type below command

sudo apt-get install --reinstall gnome-terminal

then try again with relogin/restart.

@rajadenupula Please read the question carefully, i cant access the terminal, so how can i write a command in it? Do u mean from other account (but that wont be of any use will it?) – Ayush Nov 16 '13 at 16:57

you giving right info ? – Raja Nov 16 '13 at 17:07
Yes i am @rajadenupula – Ayush Nov 17 '13 at 14:16

Hmmm. Check the file permissions of new user ( you are logged in as new-set user ! ) for the files of terminal. I assume you have bash as terminal set ? So do find out, where bash is located:

whereis bash

When there is output like /usr/bin/bash - then do:

ls -al /usr/bin/bash

Only in case the output at beginning of line is DIFFERENT than this here: -rwxr-xr-x

... then you should do:

sudo chmod 755 /usr/bin/bash

The directories /usr and /usr/bin should be in permission-state of chmod 755 too.

Hope this helps.
