我從 14.04 升級到 16.04。啟動後，終端機tty1打開，並重複一則訊息：
brcmsmac bcma0:1: brcmsmac: brcms_ops_bss_info_changed: disassociated
brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: false (implement)
我有一個雙引導系統（Windows引導程式仍然工作），我還有nvidia geforce。
ifconfig顯示wlan0和eth0都已啟動，但沒有ip。
你能找出問題所在嗎？我該如何修復它？
謝謝。
答案1
您顯示的資訊只是無線設定本身的 dmesg。
試按Ctrl+ Alt+F7
除此之外，除了啟動到 tty1 而不是 tty7 之外，您的系統似乎很好（根據您的描述）。
答案2
也許我沒說清楚，tty7只是黑屏，這就是問題所在。
帶有 AGP 搜尋結果的 dmesg：
