从16.04lts升级到18.04无法进入桌面

[zzugyl]

小米笔记本13.3air Intel i5-6200U,Nvidia 940mx
在16.04的时候一直使用集成显卡，偶尔使用nv显卡，因为经常出问题，所以基本上是使用集显。
昨晚用命令行升级到18.04后，无法进入桌面。tty可以登录，尝试过xdm,lightdm都无法进入桌面，recovery模式也无法进入桌面。
尝试安装系统推荐的nv显卡驱动 nvidia-driver-390,切换成nv驱动模式也无法进入桌面。
现在进系统如下图，闪烁4下，然后静止，进不去桌面。麻烦大家帮看看。

好像没有使用上NVIDIA的驱动，仍然使用了系统自带的nouveau，怎么切换？

我现在安装了nv显卡驱动 删除了系统自带的nouveau

@poloshiao
从16.04使用nv显卡驱动，不管开源闭源，都很折腾。我一般改用Intel集成显卡。
卸载了所有nv相关驱动，使用Intel驱动启动。现在用文字模式启动裸X没问题。然后安装gdm或者lightdm，还是进不来桌面。
有什么检测方法？

卸载了所有nv相关驱动，使用Intel驱动启动。现在用文字模式启动裸X没问题。然后安装gdm或者lightdm，还是进不来桌面。

1. 雙顯卡 除非你的 Bios 有 關閉 集顯 (Intel) 或 獨顯 (Nvidia) 否則 無法變成單顯卡 此時 只能使用 軟件程式操控
1-1. 文字模式 一般對於 3D 支援 要求不很高
1-2. 也有一些桌面或圖形環境進程 對於 3D 支援 要求不很高 例如
https://wiki.ubuntu.com/BionicBeaver/Re ... 8.04.1_LTS
Lubuntu
Ubuntu Budgie
Ubuntu MATE
Xubuntu
1-2-1. 你可以額外安裝其桌面或進程套件 然後重開機 選擇該進程 登入
1-3. Ubuntu 預裝的 ubuntu (on Xorg) 及 unity, Gnome, Kubuntu. Ubuntu Kylin
對於 3D 支援 要求很高
需要安裝/啟用合適顯卡驅動

01:00.0 3D controller [0302]: NVIDIA Corporation GM108M [GeForce 940MX] [10de:134b] (rev a2)
Subsystem: Device [1d72:1602]
Kernel driver in use: nouveau

2. 目前 作用中驅動 還是 開源驅動 nouveau
2-1. 如果你已安裝好 nvidia-driver-396 通常 它應該會自動把 開源驅動 nouveau 加入 載入 黑名單
2-2. 否則 你需要手動 把 開源驅動 nouveau 加入 載入 黑名單

3. 你還有另一個選擇 試試安裝第三方軟體 bumblebee
3-1. 不要把 開源驅動 nouveau 加入 載入 黑名單
3-2. 新手 建議 把已經安裝過的閉源驅動 nvidia 全部清空

4. 歡迎再貼文 同時 補上
4-1. sudo lshw -numeric -class video
4-2. sudo ubuntu-drivers devices
4-3. sudo efibootmgr -v
4-4. echo $DESKTOP_SESSION
4-5. nvidia-settings --glxinfo | grep "OpenGL version string"
4-6. lsmod | grep nouveau
4-7. lsmod | grep vulkan
4-8. lsmod | grep nvidia
4-9. sudo dpkg -l | grep nvidia
4-10. sudo prime-select query
把指令及結果直接 選取/複製 貼上來

谢谢版主，已经解决了。
问题出在unity-greeter的依赖libatk---> glib。
我安装meld的时候，升级glib，导致原来unity-greeter的依赖函数变更。

[onceonce]

请问，是如何解决的呀。谢谢了。
现在是刚从16.04升级到18.04，然后桌面什么也没有
