（整理していないメモ）携帯ディスプレイを流用した機械にFreeBSDを入れる

最終目標

課題

一段下げた目標

当面の対策

最新の進行状況と課題

1 scfbで画面を右に回転させる

2 Intel-driverに代える

3 UEFIの段階でなんとかする

Linuxのインストール

FreeBSDのインストール

グラフィカルなインストールが可能なBSDの検討

結局普通のFreeBSDを入れることにする

ubuntu側のX関係のファイルの状況

/etc/X11/xinit/xinitrc

. /etc/X11/Xsession

/etc/X11/xinit/xserverrc

exec /usr/bin/x -nolisten tcp "$@"

/etc/X11/xorg.conf.d/10-amdgpu.conf

Section "OutputClass"
	Identifier "AMDgpu"
	MatchDriver "amdgpu"

まずは単純に起動させてみる
