升级到18.04后发热严重

[arthurfk]

在16.04时关闭独显后基本不发热，风扇也基本听不到声音，更新同样关闭独显后风扇声音很大，续航下降了50！难道是gnome的原因吗

把下面指令 複製 貼進終端機 執行
1-1. uname -a
1-2. sudo lspci -knn | grep -A2 -i "3d\|display\|vga"
1-3. sudo lshw -numeric -class video
1-4. sudo ubuntu-drivers devices
1-5. sudo efibootmgr -v
1-6. echo $DESKTOP_SESSION
1-7. sudo cat /etc/os-release
把指令及結果直接 選取/複製 貼上來

1. 雙顯卡 可以獲得 Ubuntu 自己編譯的 kernel 支援
但是 必須安裝 閉源驅動 nvidia
1-1. 目前 nvidia 顯卡
GM204M [GeForce GTX 970M] [10DE:13D8]
作用中 顯卡驅動 是 開源驅動 nouveau

sudo ubuntu-drivers devices
...
model : GM204M [GeForce GTX 970M]
driver : nvidia-driver-390 - distro non-free recommended
...

1-2. 安裝 nvidia-driver-390
sudo apt install nvidia-driver-390
1-2-1. 參閱
https://packages.ubuntu.com/bionic/nvidia-driver-390
1-3. 把 開源驅動 nouveau 加入載入黑名單
1-3-1. 方法參閱
https://askubuntu.com/a/868209
1-4. 然後 重新開機

2. 補充
網路上 有許多 Ubuntu 18.04
把 開源驅動 nouveau 加入載入黑名單 會有問題的貼文
還沒看到 徹底解決方案

[foxbabymm]

正式版还没发布啊，官网没动静啊 ~

把 開源驅動 nouveau 加入載入黑名單 會有問題的貼文
還沒看到 徹底解決方案

我按照上述贴文操作后还是有问题，明明已经加入黑名单了，看起来nouveau还在工作

我按照上述贴文操作后还是有问题，明明已经加入黑名单了，看起来nouveau还在工作

1. 看看 nouveau 是否還被載入
lsmod | grep nouveau

2. 看看 GeForce GTX 970M 是否還被 nouveau 佔用中
sudo lshw -numeric -class video

或

笔记本掉电厉害是因为这个吗？我的也是双显卡的本本，重新安装了再测试一下！
