最近把本子换成ubuntu系统。但是开机的时候经常会碰到如下问题：

1、光标指针找不到。不能用触摸板，但是在设置里面可以看到触摸板设置部分，说明设备是认出来的。个人理解。
不明所以然，重启一下就正常了。

2、无线网卡没有启动。
右上角点开wifi发现，wireless is disabled by hardware switch。
lshw看一下，
*-network DISABLED
description: Wireless interface
product: Wireless 7260
vendor: Intel Corporation
physical id: 0
bus info: pci@0000:02:00.0
logical name: wlan0
version: 83

无线网卡没有启动，重启一下又ok了。

还有一个问题，ubuntu的驱动管理additional drivers里面，搜不到任何相关驱动，提示 no additional drivers available.
好久不用ubuntu了，好多东西都忘掉了，求帮忙。
系统是14.04版本的。

多谢

1. 原因可能很多
優先確認 顯卡驅動 是否已合適安裝/啟動
把下面指令 複製 貼進終端機 執行
1-1. uname -r
1-2. sudo lspci -knn
1-3. sudo lshw -numeric -class video
把結果直接 選取/複製 貼上來
不必擷圖

2. 查閱你的電腦使用說明書
有沒有 從 開機韌體 或 鍵盤 打開/關閉 的選項
是不是 雙重開機 (另外安裝了 Windows)

最后这个命令没有任何输出

檢查一下 藍芽裝置 是否處於被關閉狀態

蓝牙是关闭的啊，我自己关的。这个和我上面列出来的那些现象有关系吗？

1. r8169 不是合適的驅動
