This was around 10 years ago and I was writing from fuzzy memory. Is it really wrong in an overall sense when you do not omit from the quote all that I wrote, in particular this part?: "and avoiding encountering a dastardly video mode switch known as "flicker" before a GUI login greeter appeared." Fedora wanted to get rid of a /horrible/ /demon/ called flicker, as well as move the GUI to tty1, and later in ancient history, Redhat instrumentality Leonnart's systemd incorporated TTYVTDisallocate=yes as a partial means to accommodate it.

Indeed the original thread's complaint's cause was/is clear_console, but only on Debian and whichever of its derivatives follow suit. AFAIK, none of the non-.deb distros I've used (e.g. Fedora, {open}SUSE) have ever utilized it. It's never bothered me on Debian or anywhere else because I like what shows up, when allowed, on tty1, leaving it remain uncleared, reminding me this is not Windows, and logging in intentionally only on tty2 and up. Thanks for the history refresh from "The world wants you to clean your screen" and mailing list links. I had no idea there were so many gettys, and Greg W's http://mywiki.wooledge.org/SystemdNoClear is now bookmarked so I can switch to accepted practice for overriding stupid settings when the urge strikes. -- Evolution as taught in public schools is religion, not science.
