Why is Ubuntu 18.04 halting after login since upgrade from 17.10?

Question

I have an Acer Aspire VX 15 (Intel Core i7, NVidia Geforce GTX 1050, 32 Gb RAM, HDD 1Tb).

I had Ubuntu 17.10 installed and everything was working fine. Then I upgraded to Ubuntu 18.04 and now, after I login via GDM (in graphics mode) the system halts. It becomes completely frozen.

However, if I press Ctrl+Alt+F2, switch to text mode, and then login in the console, the system works fine (in text mode) and do not halt.

Does anybody else has a similar problem?

Do you know how to fix this or how I can diagnose the problem?

Answer 1

I seems the problem was with the graphics driver. The default installation uses the Nouveau driver. After I installed the NVIDIA recommended driver (nvidia-driver-390) everything seems to be working fine.
