startxしても全くnouveauが立ち上がらなかったので問題を解析する
Xorg.log
まずLinux使いであればあまり見たくはないXorgのログを見ていこう。

dmesg
次にdmesg、grepすればnouveauが立ち上がっていることが確認できるはず
# dmesg | grep nouveau
何も出ない…、modprobeを実行する
modprobe nouveau modeset=1
再びdmesg、今度はうまく動いた
# dmesg | grep nouveau

modprobeを次回起動時も有効にする
/etc/modprobe.d/以下を見に行く
# ls /etc/modprobe.d/
alsa-base.conf.dpkg-bak dkms.conf modesetting.conf oss-compat.conf
blacklist.conf fbdev-blacklist.conf nvidia-installer-disable-nouveau.conf radeon-kms.conf
ん？
# cat /etc/modprobe.d/nvidia-installer-disable-nouveau.conf
# generated by nvidia-installer
blacklist nouveau
options nouveau modeset=0
ファイルが存在しません。
nvidia-installer-disable-nouveau.confに邪魔されていたようです。削除します。
