我前兩天將Linux換成 14 的 LTS 除了剛開使沒WiFi可用外
其他都還算穩定,約莫在昨晚更新了WiFi Driver讓WiFi復活
之後有登出一次,沒什麼大礙,但昨晚蓋上電腦後今天打開出現
快淹出來的Consle 畫面
我查國外論壇有看到有人討論 WiFi Driver 造成的 Null Pointer
不過主要都看到在秀 erro Message 所以我還是不太知道要怎麼修復
這個問題 ,提供一些資料給各位大大參考 , 我待會會繼續測試有哪些
error 如果還有什麼需要的資訊也請各位大大告訴我
感謝

ps: 我剛 repeat 一次 crash , 是在google chrome 開啟
Netflix 網路電影服務時,直接關上筆電讓他自動logout的話
會crash , 而 chrome 沒有開啟的狀態可以正常logOut
