[systemd-devel] [PATCH] login: rerun vconsole-setup when switching from vgacon to fbcon

[Ray Strode]

From: Ray Strode <rstrode at redhat.com>

The initialization performed by systemd-vconsole-setup is reset
when changing console drivers (say from vgacon to fbcon), so we
need to run it in that case.

See

This commit adds a udev rule to 71-seat.rules to make
systemd-vconsole-setup get run when the fbcon device becomes available.
