Yet another option might be not using any display manager and instead use
startx (or its wayland equivalent).
For that purpose RAM Adjusted Desktop Starter - Kicksecure (
rads) could be modified.
(Whonix is based on Kicksecure.)
If no display manager is installed and if there is enough RAM and if
startx is available, start it.
How about Whonix-Host?
(Would equally apply to Kicksecure host.)
- Pre-configured style: Should have display manager and no default autologin? Also for logon password at every boot required.
- Minimal style: autologin using startx by default. Display manager installation, logon password setup should be left to the user?
Display manager login password has limited use anyhow when already using Full Disk Encryption - Kicksecure → Protection against Physical Attacks.
