Hello friends from all over the world 
I am having a strange boot problem with Cinnamon on a Lenovo Thinkpad T440 laptop. Indeed, after the grub screen I have a black screen! By adding the option nomodeset in the edit mode of the grub at startup, I can start and I have the login screen!
Strangely, I installed the DE Gnome and the boot is done without problem!
If you have an idea? A problem with Cinnamon?
I am posting the result of the inxi -Fxxxz command, the integrated graphics chipset is Intel Haswell-ULT.
