Problem displaying GUI after update to ubuntu.

Taylrl · 11-16-2011, 12:38 PM

Hi,

I recently chose to download an update to what I think was ubuntu 10.10. Now when I reach the login screen and type in my details it keeps on bringing me straight back to the login screen. I can login to the terminal using ctrl+alt+F4 but apparently there is now no specified display. I was wondering if someone might be able to help me get back to the GUI?

Thanks in advance!

Read your ".xsession-errors" file in your user home directory, there should be answer.

Thanks.

When I type:

cat .xsession-errors

It says:

/etc/gdm/Xsession: Begining session setup...
/home/myname/.profile :23 :Syntax error: Undetermined quoted string

Any ideas what this means?

Error in "/home/myname/.profile" file, show it.

Ok, my .profile contains;

#~/.profile: executed by the command interpreter for login shells.
#This file is not read by bash(1), if ~/.bash_profile or ~/.bash_login
#exists.
#see /usr/share/doc/bash/examples/startup-files for examples.
#the files are located in the bash-doc pacakge.

#the default umask is set in /etc/profile; for setting the umask
#for ssh logins, install and configure the libpam-umask pacakge.
#umask 022

#if running
if [ -n "$BASH_VERSION" ]; then
#include .bashrc if it exists
if [ -f "$HOME/.bashrc" ]; then
. "$HOME/.bashrc"
fi
fi

#set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
PATH="$HOME/bin:$PATH"
PATH="$home/myname/Library/cuda/bin:$PATH"
PATH="$home/myname/Library/cuda/lib:$PATH
PATH="$usr/bin/gcc:$PATH$"
".profile" 25 lines, 802 characters
fi

I noted the missing " at the end of line 24 and corrected it but still not able to display anything or login. Can anyone see where there might be another mistake? Would a mistake in this file lead to me not being able to login? Thanks again :-)

You have following errors here:

Code:

PATH="$home/myname/Library/cuda/bin:$PATH"

Here you use "$home" at the start. If you want your home folder use "$HOME" (watch capital letters) and if normal path - use "/home/myname". "$HOME" is preferred.

Code:

PATH="$home/myname/Library/cuda/lib:$PATH

Same here, by the way, are you sure you have executable files in "lib" directory, I suppose there are only library files, and as I known PATH is not searched for libraries during compilation.

Code:

PATH="$usr/bin/gcc:$PATH$"

Here you should remove first and last "$" sign (I suppose you have no defined variable $usr anywhere), and once again, do you have this directory gcc, as in my system this is a file, and in PATH variable you specify directories to search - not files.

Code:

".profile" 25 lines, 802 characters

This line should not be in this file.

So the correct file should look that, but consider removing two last lines before "fi", as I noted ealier they are probably unnecessary:

Code:

#set PATH so it includes user's private bin if it exists
if [ -d "$HOME/bin" ] ; then
 PATH="$HOME/bin:$PATH"
 PATH="$HOME/Library/cuda/bin:$PATH"
 PATH="$HOME/Library/cuda/lib:$PATH"
 PATH="/usr/bin/gcc:$PATH"
fi

Also please use CODE tags around your code, beacause it is more readable than and we can see real file not parsed by forum. Also if you still can not login, look again in ".xsession-errors" and show contents - there will be another errors.
