I have a Lenovo P53 which has hybrid graphics (Intel and Nvidia). I have
chosen to use "discrete graphics" which means that I am using the Nvidia
card.
Until a recent update everything was working fine. After the automatic
update and the upgrade from kernel 5.3.0-28 to 5.3.0-40 (and possibly an
upgrade of the Nvidia drivers) the opearing system hands after I enter
the login credentials. I have tried to get some output from the startup
screen by removing the "quite splash" from the grub file but it does not
give any error information. It just hangs.
I am using Nouveau to login to the computer, but with Nouveau I the HDMI
port is not working
I can try to add more debugging information if one helps me to collect
it
I am using Ubuntu 18.04.4
