Invisible login screen

[heavenleft]

When I boot Mint I cannot see the logon screen but it is there because when I type my password and hit enter I can logon. On the other hand if I connect an external monitor the logon screen is shown on the monitor.

So far I tried setting nomodeset on GRUB_CMDLINE_LINUX in in /etc/default/grub but that resulted in a black screen with cursor (non blinking) after boot. Also secure boot is disabled on my PC (for other reasons). So secure boot enabled or disabled changed anything.

My system details:
RELEASE=19.1
CODENAME=tessa
EDITION="Cinnamon"
DESKTOP=Gnome
TOOLKIT=GTK

I have Nvidia driver nvidia-driver-390 (also tried switching to xserver driver to no avail).

Grateful for any help.

Please generate an overview of your system like this:
- Launch a terminal window (this is how to launch a terminal window);
- make the terminal window full screen, to avoid chopped lines;
- Copy/paste this command into the terminal:

Code: Select all

inxi -Fxz

(if you type: the letter F is a capital letter)

Press Enter.

Copy/paste the output in your next message.
