Would like to change Login screen. Have LCARS-Desktop GDM (Widescreen)

Be careful what you try (unless in "impermutable mode", it's awesome for :madness: ) as:

  1. Some abandon-ware does not cater for amd64 ....requiring additional compatibility installments.
  2. Very old stuff is built on different deprecated libraries and/or require other deprecated software.
  3. Older abandoned software, not being watched/used much anymore, my contain vulnerabilities that weren't even known at the time of creation.

In general, most users run single user machines privately so auto-login on boot-up is the fastest and safest option IMO....the only caveat being a forgotten password which can easily be reset if needed (in the last part of):
