I ran sudo apt-get dist upgrade. Apparently everything went well except that when it was done, in the terminal said there was an error. I didn't mind about it and shut system down. When I turn computer on again, everything was "ok" and then the screen sessions was in front of me... I selected my session, gave my password, pressed enter and it took me back to the sessions list. With every session happens the same: I can't log in. I noticed the mouse was not working. I connected one in another usb port and worked but nothing was clickable. There were some changes in the environment: different font, different bar color on top...
I don't know what to do. I tried to use a previous version (the one shown in the start) and happens the same. I really need to get this fix. Don't remember what was the error shown in terminal.
it's linux mint maya 12. I'm new using linux. Didn't know exactly what I was doing when I ran that in terminal.
