I recently upgraded my laptop from Lubuntu 12.04 to 14.04.1 and the upgrade process seemed to go fine.

However, when I went to login as my normal user, I encountered an issue. The background loaded up, but none of LXDE or LXPanel showed up, leaving me with an empty desktop and nothing else except two errors.

I thought that this was weird, so I just figured something had been messed up and would be fixed by a reboot. But it wasn't. I then tried logging in as guest, and it's just fine. I checked the ~/.xsession-errors file (for my main user, not guest, did it via TTY1) and this is what I got:

Script for ibus started at run_im.
Script for auto started at run_im.
Script for default started at run_im.
init: Unable to register as subreaper: Invalid argument
init: lxsession main process (1649) killed by TERM signal
init: Disconnected from notified D-Bus bus
init: job dbus failed to stop
init: job upstart-dbus-session-bridge failed to stop
init: job upstart-dbus-system-bridge failed to stop
init: job upstart-file-bridge failed to stop

I also read the sometimes removing the ~/.Xauthority file can help, if the ownership is messed up. ls -l /home/MYUSER/.Xauthority tells me -rw------- 1 MYUSER MYUSER 60 Aug 16 09:57 /home/MYUSER/.Xauthority. Should that be root or something else, or should I try deleting that and ~/.profile.

Here's what ~/.profile looks like:

# ~/.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 package.

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

# if running bash
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"
fi

Should I post the output of dmesg?

I'll try and get a screenshot, but does anyone have any idea what could be causing the desktop (LXDE/LXPanel) not to display?

EDIT I attempted removing the ~/.XAuthority file, but that didn't seem to do anything.
