That essential feature that was > stripped out of the kernel at around 5.4.x has returned! It is commit 087b6cb17df5834d395ab72da3f937380470ba15, between v5.4.65 and 66. Perhaps also 0d123a8c64fde433a, cf5a7ded53652c3d63d72, and possible other stuff. > Only this time, it's even better! Instead of one scrollback buffer > shared between all tty's, there's now a buffer for each tty. Great, no more missing data when switching vts. Btw, wasn't that added in commit aabd31c421ddc730edf6d89c4ed3885e4fca5e30 but turned off by default. ... > One ord two features haven't (yet) been implemented - having a > single scroll buffer shared amongst all tty's isn't there, ... Is there any reason to share the buffer ? > Bug reports and other comments are welcome, of course. git log drivers/video/console/vgacon.c etc. can give some ideas what one is up against.
