I have Ubuntu on my PC installed and also windows. Every OS is on another Partition of my HDD - I worked like this the last few months and everything was fine.

An hour ago I was on Linux, then restarted to get to windows to do smth than restarting to get back zu Ubuntu - and here is the problem ... the login does not appear!

I tried it 5 times with restarting and restarting an wait a while and so on ... nothing helped me out.

When Ubuntu starts the background appears (the login background. Its a purple background color. In the normal way now the Login will appear and a sound is playing. But it doesnt appear.

I found a few information with like the same problem and I read to press CTRL+ALT+F2 to get to the console. But when pressing these buttons nothing happend. I tried this with: CTRL + ALT + (F1 - F12) Never anything happend ...

What can I do ? The data on my linux system are necessery for my work and it would be very very sad if I would loose them ...

Edit: I installed Ubuntu with wubi

I do not know about LightDM Ubuntu uses, but in KDE that would happen if you have no write permissions to your own home folder. Did you do something to permissions? –  Barafu Albino Aug 10 '14 at 17:23
Is your PC is laptop? If answer is 'yes', next question is: Do You have connected second monitor to PC? I have similar situation whec 2'nd display is connected, but when there is black screen I type my password and press enter, OS behave in normal way. –  wmarchewka Aug 10 '14 at 17:47
I have a PC with 2 Monitors and this worked good for me but I will try to disconnect the second monitor and type in my password. Another information (maybe necessery: I installed Ubuntu via Wubi) –  Timo Rütten Aug 10 '14 at 17:48
No, nothing. I started Windows to upload smth from my Windows partition via FTP and then restarted to Ubuntu ... :/ I installed Ubuntu with Wubi and in there FAQ they said that repairng the partition where Ubuntu is installed could help but nothing changed. –  Timo Rütten Aug 10 '14 at 17:49
Tell what will happen in Your case with one monitor, I'm very interested in ;) –  wmarchewka Aug 10 '14 at 17:55
