Hi ,
try to login from Console. When login screen comes up , press Ctrl+alt+F2 and login with username & password.

Write down (maybe to a paper or mobile photo) below commands and run them one at time.

=================================
sudo service lightdm stop
sudo apt-get install -f
sudo dpkg --configure -a
sudo apt-get update
sudo apt-get dist-upgrade
unity --reset
sudo serivce lightdm start
================================
6th command will reset your unity settings (include Dash) . Wait for 10-15 minutes and if not complete then stop it with Crtl+C .
Then give next command.

I hope this helps to solve your problem.
Thanks

When I log out, then use ctrl/alt/f2 i enter my user name and my password, and they are not recognized. i assume that is the console that you mean, i used the log out inder the gear thingee. so i don't get to a terminal and can't enter the commands that you listed.

i guess it is just broken and can't be fixed.

Ctrl+Alt+T will bring up terminal. If I use Ctrl+Alt+F2, I have same problem you have. It will not accept the correct user name and password. Only way to get out of that place is to (Press and Hold- Alt+Print screen/Sysrq+slowly spell R E I S U B) I Googled, difference between Console and Terminal in Linux. Got different answers, some said they are same thing, some said they are different things, some said it is correctely called Terminal Console. ???? Try putting NiklTh's commands in terminal. Ctrl Alt T will bring up terminal. i guess it is just broken and can't be fixed. Your statement. May be broken, but there will be someone here that can fix it.

got a bunch of "warn: this should not happen maybe you should submit a bug
report"

now i get a bunch of internal error statements and do i want to send in a
report, etc.

Hi ,
imagine this Console as a big terminal without Desktop Environment(others say Virtual Terminal or Virtual Shell) . It is another shell and must login there with your username and password. Username & password must be accepted . Try to write them more carefully.
You can always return on Desktop Environment with Ctrl+Alt+F7. But i want you to write above commands with order. After that no need to press Ctrl+alt+f7. Last command will bring up the Login screen you know and I believe your problems will solved.

Thanks

My user name and password do not bring up the terminal from console, I just keep getting the enter user name/password combo over, and over, and over ad nauseum. Dash still does not show any applications either installed or available ; Ubuntu Software Center opens then turns dark grey and stops working. I can not do the cure that was offered above.

Hi ,
Your username & password will let you to login to the Console , it will not bring up anything. I mentioned above (#5) that Console is like a big terminal, so you don't need to bring up anything. Only thing you must do is to login (to Console) and run the commands from #1st answer.
But because you will not have any environment you must run the commands carefully. Write them on a paper of take a photo of #1st answer with your mobile phone.

If you cannot login to the Console then either you give a wrong password or something is going on with your password.

Look, it exists another way to run above commands . Pay attention

1. Boot from recovery mode (usually is the second entry in grub menu) . If you don't have a grub menu then during pc boot hold "shift" key down until grub menu appears.

2. select root

3. First of all , give this command
+++++++++++++++++++
mount -o rw,remount /
+++++++++++++++++++

4. then give these commands
++++++++++++++++++++++++
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install -f
sudo dpkg --configure -a
reboot
++++++++++++++++++++++++

Thank you

I booted from recovery mode, entered root, entered commands; all sorts of lines of print were scrolled on screen. Dash still does not show applications, Ubuntu software center opens and grays out and becomes unresponsive. Sorry, i do know how to type and checked the commands before hitting enter.

Hi ,
can you boot again from recovery mode and select "FailSafeX" to boot in
environment with low graphics mode ?

If you boot in such environment you can run the command
++++++++++
unity --reset
++++++++++
in a terminal (ctlr+alt+t) and see if unity settings restored.

Another option might be to boot to the regular Ubuntu and choose Ubuntu-2d
from the login screen and see if things work there.

Thank you

This may help. My user name and passwork never worked. Tried many times. Since my password has letters and numbers, I used keypad and numberpad. Will not work. Look at this site, will tell what to do.
