如题，点一些应用也黑屏，比如说点亚马逊的快捷方式会黑很久，有时候还不会自动唤醒，要按电源键屏幕才亮。
升级过内核也不能解决，只有重装的3.19.0-X 之后的版本才不会出现黑屏现象，从原有内核升级到前面所述版本也不会解决黑屏问题。
有大神知道原因么？

1. 是 UEFI 或 Legacy Bios 開機韌體 ?
2. 雙重開機 ?
3. 把下面指令 複製 貼進終端機 執行
3-1. uname -r
3-2. sudo lspci -knn
3-3. sudo lshw -numeric -class video
3-4. sudo ubuntu-drivers devices
把結果直接 選取/複製 貼上來

第四条没有运行结果

1. 一般安裝 linux-image-3.16.0-44-generic
只有音樂方面需要 realtime 即時設定的功能 才需要 linux-image-3.16.0-44-lowlatency
1-1. http://packages.ubuntu.com/search?suite ... chon=names
1-1-1. 套件 linux-image-3.16.0-44-generic
Linux kernel image for version 3.16.0 on 32 bit x86 SMP
1-1-2. 套件 linux-image-3.16.0-44-lowlatency
Linux kernel image for version 3.16.0 on 32 bit x86 SMP
1-2. http://askubuntu.com/a/401416
What exactly is generic version of ubuntu ? how it differes from other versions?
linux-image-lowlatency: I think this is intended for eg, audio editing where low latency is important (see Why to choose low latency kernel over generic or realtime ones? ).

1. 安裝
linux-headers-3.16.0-44-generic
linux-image-3.16.0-44-generic
linux-image-extra-3.16.0-44-generic
1-1. 重開機
選 3.16.0-44-generic 開機

2. 只有 音效方面的專業 才會選用 3.16.0-44-lowlatency
2-1. 下面兩個套件 可以保留 也可以移除
linux-headers-3.16.0-44-lowlatency
linux-image-3.16.0-44-lowlatency

3.16.0-44-generic
按照上面操作都处理了一边，切到上述内核了，也是开机黑屏几秒钟，打开设置又黑几秒钟。

1. 可能是顯卡硬件/驅動軟件 沒有合適配對 引起的
能夠登入 tty1 嗎

2. 按一下 ctrl + alt + F1
登入 tty1

3. 如果可以
3-1. sudo apt-get install pastebinit
3-2. sudo lspci -knn | pastebinit
會回應 http://paste.ubuntu.com/xxxxxxx # xxxxxxx 是一組數字
把 http://paste.ubuntu.com/xxxxxxx 貼上來
3-3. sudo lshw -numeric -class video | pastebinit
會回應 http://paste.ubuntu.com/xxxxxxx # xxxxxxx 是一組數字
把 http://paste.ubuntu.com/xxxxxxx 貼上來

3.2返回结果 http://paste.ubuntu.com/13843484/
3.3 返回结果 http://paste.ubuntu.com/13843502/

1. 顯卡 Intel Corporation Xeon E3-1200 v2/3rd Gen Core processor Graphics Controller [8086:0152]
目前 作用中驅動 i915 看起來 已經正常作用中

2. 請增加
uname -a

我也遇到同样问题。楼主解决了吗？

我换了一台显示器就好了
