ログインループ–「badvalue（整数パラメーターが操作の範囲外）」– 16.04？

手動でインストールされたNVIDIA361ドライバーを使用してUbuntu16.04LTSを実行していました。ドライバをv367にアップグレードした後、ログインループでUnityからロックアウトされ、 .xsession-errorsに次のエラーが表示されます。 ：

X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  154 (GLX)
  Minor opcode of failed request:  3 (X_GLXCreateContext)
  Value in failed request:  0x0
  Serial number of failed request:  32
  Current serial number in output stream:  33

このエラーメッセージをWebで検索しても、関連する結果は多くありません。

関連：ログイン時にダイアログを表示しますか（bashスクリプト）？

v364にダウングレードしてから、v361に戻して無効にしました
xserver-xorg、xserver-xorg-core、nvidia *、lightdmを無効にしました
ubuntu-desktopを再インストールしました役に立たない

完全な再フォーマットと再インストールは非常に混乱を招くため、絶対に避けたいと思います。

.xsession-errorsのエラーメッセージ 常に同じままです。設定やパッケージ、ライブラリを完全に再フォーマットして再インストールせずに、パージ/復元/リセットして正常な状態にするにはどうすればよいですか？

承認された回答：

+iglxを追加する /usr/share/lightdm/lightdm.conf.d/50-xserver-command.confのxserver-commandに 。

[SeatDefaults] 
# Dump core 
xserver-command=X -core +iglx

その後、再起動するか、Ctrl-Alt-F1でログインし、sudo service lightdm restart 。

チャームのように機能します
