For transport reasons I had disassembled and re-installed on a different case, my computer (with windows 10 and fedora 30).

The technician has successfully performed the reassembly operation, however, on booting Windows 10 the computer works correctly, while booting via fedora the procedure allows you to log in (with a previously registered user name) but after that, the graphical menu environment does not appear .

I can use still fedora in text mode (by Cntrl Alt F 1 -F3), however I cannot activate the graphical menu environment.

How to activate the disappeared graphic environment?

some advice ?
