前几天升级到15.04之后发现在安装NVIDIA的显卡驱动（使用体系自带的“附加驱动”安装）之后，系统在启动时会显示Starting Version 219，然后就一直卡在这儿无法进入图形界面，但是可以使用别的电脑ssh到这台机子上。因为工作原因又不能不安装NVIDIA驱动，我把系统自带的各个版本的NVIDIA驱动都尝试了一个遍（系统自动的最新驱动和NVIDIA官网上的最新驱动是同一个版本），全都是这个样子。从网上搜了好多，发现似乎是ubuntu15.04版本的通病，但是找到的解决方案在我这儿都不管用：
1. 升级Linux内核到4.0：不管用，照样显示Starting Version 219，无法进入图形界面
2. 使用 ：不管用，显示Failed to execute operation: No such file or directory
3. 后来发现我的显示管理器是lightdm，改用：不管用，显示如下：
Synchronizing state for lightdm.service with sysvinit using update-rc.d...
Executing /usr/sbin/update-rc.d lightdm defaults
Executing /usr/sbin/update-rc.d lightdm enable
The unit files have no [Install] section. They are not meant to be enabled
using systemctl.
Possible reasons for having this kind of units are:
1) A unit may be statically enabled by being symlinked from another unit's
.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,
D-Bus, udev, scripted systemctl call, ...).
问题依然如故

目前按照临时解决方案，在GRUB引导时使用recovery mode，倒是可以进入正常启动并进入图形界面，但是这样每次开机实在太麻烦了。
不知有哪位大神能帮忙解决一下

這應該是 systemd 的版本號
http://packages.ubuntu.com/vivid/systemd

ssh 應該是 連接到 tty1 的 console
跟圖形 tty7 無關
但是可以用來下 console 指令

这个我知道啊，但是我想知道怎么才能进入系统。

既然你可以使用 ssh 登入 tty1

如果試用 root 登入 tty1 下述指令 不必 加 sudo
(但是 不建議 使用 root 登入 tty1)

1. sudo apt-get install pastebinit

1-1. uname -r | pastebinit
會回應 http://paste.ubuntu.com/xxxxxxx # xxxxxxx 是一組數字
把 http://paste.ubuntu.com/xxxxxxx 貼上來

1-2. 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

1-3. 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

1-4. sudo ubuntu-drivers devices | pastebinit
會回應 http://paste.ubuntu.com/xxxxxxx # xxxxxxx 是一組數字
把 http://paste.ubuntu.com/xxxxxxx 貼上來

2. 試試 能否從本機 登入 recovery mode

這個指令 你希望達到什麼目標

1. 顯卡
GeForce GTX 460
1-1. 目前作用中驅動 閉源驅動 nvidia

1-2. xserver-xorg-video-nouveau 提供 開源驅動 nouveau
1-2-1. lsmod | grep nouveau
看看 開機 開源驅動 nouveau 有沒有 被載入
1-2-2. 要讓 閉源驅動 nvidia 有作用 必須把
開源驅動 nouveau 加入 開機載入 黑名單
http://askubuntu.com/questions/619902/i ... 290#620290
1-3. 15.04 雙顯卡
如果安裝 閉源驅動 nvidia 一直不成功
看看 有沒有 gallium 開源驅動模組 在作怪
如果有 也把它列入 載入黑名單
http://discourse.ubuntu.com/t/vivid-ver ... phics/2114
http://askubuntu.com/questions/614128/1 ... 219#614219
1-4. 在 Ubuntu 從 Ubuntu 或 PPA 套件庫 安裝 閉源驅動 nvidia 參見
https://help.ubuntu.com/community/Binar ... wto/Nvidia


2. Intel 顯卡 沒有 被驅動
2-1. Ubuntu 預裝 xserver-xorg-video-intel 提供 Intel 顯卡 的 開源驅動 i915
2-2. 看看 開機 開源驅動 i915 有沒有 被載入
lsmod | grep i915
