升级后开机黑屏

我从 14.04 升级到了 16.04。启动后终端打开tty1，并重复显示一条消息：

brcmsmac bcma0:1: brcmsmac: brcms_ops_bss_info_changed: disassociated 
brcmsmac bcma0:1: brcms_ops_bss_info_changed: qos enabled: false (implement)

我有一个双启动系统（windows 引导加载程序仍在运行），我也有 nvidia geforce。

ifconfig显示wlan0和eth0都已启动，但没有ip。

您能找出问题所在吗？我该如何修复它？

谢谢。

答案1

您显示的信息只是无线配置本身的 dmesg。

尝试按Ctrl+ Alt+F7

除此之外，除了启动到 tty1 而不是 tty7 之外，您的系统似乎很好（根据您的描述）。

答案2

也许我没有说清楚，tty7 只是黑屏，这就是问题所在。

dmesg 中的 AGP 搜索结果：
