I have installed F18 since late January, until then I used to work with Debian, I don't know a lot about linux, just the basics.
Besides Gnome 3.6, I also installed Cinnamon and Mate for test reasons and I ended up using cinnamon as my basic graphic environment.
Suddenly, last Friday, after the login screen, the system doesn't start any graphical environment.
I hard-rebooted and tried another session and it was the same situation.
No matter what graphical environment i tried, nothing starts and it only shows the classic blue gnome screen.
So, i press ctrl+alt+F2, and then I press
in the terminal and then it starts the Gnome.
It seems like something "broke" in the X windows manager and it can not start normally.
In all other ways the system works fine, it just can not start normally after the login screen.
I haven't found out how to start cinnamon manually.
I also installed xfce from terminal but nothing changed.
Is there any way I can start cinnamon manually from the terminal ?
Is there a command to remove and then reinstall the X windows manager?
Have you got any idea about what broke and how to fix it ?
thanx in advance for your time and your patience, this is my first post in the english language i have ever done
