Hi I Found myself with this weird issue that after installing Cinnamon desktop environment on a Debian-based linux distro, with
apt-get install cinnamon, at the log-in moment even selecting cinammon or cinammon 2D the PC ends loading LXDE (wich was the first desktop-enviroment that I have installed).
Logging in as any user I have the same problem, even as root. Tried solving the problem in a "windows like style" (I am pretty new to linux) removing the software with
apt-get purge cinnamon
apt-get clean and then re-doing the same thing updating and reinstalling with
apt-get install cinnamon, however this did't work for me.
The only thing that I think that may be causing the problem is the distro I am using is just a distro created at my university and I think that may not have enough maintennance or also I know that the packages that I installed from cinnamon come from a repository in my university so maybe there are not the same packages that everybody else uses. anyways I am just guessing, I don't know exactly how the repositories works, so any advice, or idea is welcome thanks.
