From d850a2fac11e4dd45d1d3d493a5a071b06c58c99 Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Mon, 12 May 2008 14:02:39 -0700 Subject: [PATCH] vt/fbcon: fix background color on line feed Another addendum to commit c9e587abfdec2c2aaa55fab83bcb4972e2f84f9b ("vt: fix background color on line feed"). fbcon still was not doing the right thing (read: continued to do old behavior). fbcon_clear() seems to clear the new line (e.g. where your new prompt appears after doing echo -en "\e[42mfoo\n"), while scr_memsetw clears the previous one only (where "foo" appears). So just temporarily set the video_erase_char to the scrl_erase_char so that fbcon_clear does the right thing.
