From 95d67bb1ca82dc8bd75304bda891e7ad81ecd935 Mon Sep 17 00:00:00 2001 From: "Antonino A. Daplas" Date: Tue, 8 May 2007 00:38:40 -0700 Subject: [PATCH] fbcon: delay screen update when setting the mode of all consoles If the current framebuffer console is rotated (rotate != 0), doing an "fbset -a" will corrupt the current console. Fix by updating the current console only after all non-visible consoles have been updated.
