系统挂起后就回不来了，只能强行关机，求助

McRonnie · **发表于 :** 2016-08-29 14:18

ubuntu16.04，每次合上盖子挂起后再翻开，就只有两句话

代码:

924.150038 NVRM:XID(PCI:0000:04:00):79 gpu has fallen off the bus
924.150038

然后别的什么也干不了，只能强行关机
我猜测可能跟gnome有关，这是我装了gnome以后出现的，但是现在进unity也是这个情况
希望各位大神给点意见

确实是nvidia显卡的问题，我把双显卡切换到集显就没这个问题了，在独显下就会这样

登入 Ubuntu 桌面
把下面指令複製貼進終端機執行
1. uname -r
2. sudo lspci -knn
3. sudo lshw -numeric -class video
4. sudo ubuntu-drivers devices
把結果全部直接選取/複製/貼上來

目的
想要看看你是否已經安裝合適的閉源驅動

我现在nvidia-prime里选择的是集显，跟这个有关系吗？

1. 這裡推薦的是 nvidia-370

2. http://packages.ubuntu.com/search?suite ... chon=names
Ubuntu 套件庫並沒有 nvidia-370
2-1. 你這裡的 nvidia-370 是從哪個 PPA 來的還是從哪裡來的 ?
2-2. 補充目前 nvidia-370 (370.23) 是 BETA 版
http://www.nvidia.com/Download/driverRe ... 5855/en-us

3. 把下面指令複製貼進終端機執行
nvidia-settings --glxinfo | grep "OpenGL version string"
要看看目前有沒有作用中的 nvidia 版本

4. 猜測應該沒關係但不是百分之百確定
你可以在 nvidia-prime 里选择獨顯再
sudo lshw -numeric -class video
確認看看

我重装了一遍ubuntu，包括/home也格了，发现还是这样，看来是驱动有问题，我在prime里显卡选集显或者选择nouveau的驱动就不会有问题。
370应该是我之前添加PPA下的，也是想解决这个问题所以试试看升级驱动行不行，不过我印象中好像只下了367，可能下错了，不过影响应该也不大。
现在我也不去想解决这个问题了，只是不知道用nouveau的驱动好还是prime里选集显好点

你有安裝 bumblebee 嗎？
如果沒有雙顯卡需要安裝閉源驅動 nvidia.

现在装了nvidia-367的，切到集显，没出现什么问题
谢谢大神的耐心教导
