求助，14.04 U盘安装后，只有桌面壁纸和鼠标，没有工具栏，没有启动器栏。求助

[vickycq]

最简单的修复尝试 重新安装私有驱动
选择带 recovery mode 的启动项启动，再选择 failsafeX
进入桌面后，重装 nvidia-304

代码： 全选

sudo apt-get install --reinstall nvidia-304

或使用三部曲：卸载，重启，安装
注意两点
1. 卸载时使用 apt-get purge nvidia-304* 连配置文件一起清除，否则开源驱动 nouveau 会维持黑名单状态
2. 卸载后重启需编辑GRUB内核参数加入 nouveau.modeset=0


若不能进入桌面 按楼上建议 在登录界面按 Ctrl + Alt + F1-F6 进入字符界面 登录 运行上述指令
因为若干小时前刚安装过nvidia-304，缓存的deb包还在。所以预计不需要联网即可重装

回复vickycq：
选择带 recovery mode 的启动项启动，再选择 failsafeX，无法进入桌面重新安装nvidia-304.
在tty1中，sudo apt-get install --reinstall nvidia-304,重启依然无法进入桌面。

[poloshiao]

在tty1中，sudo apt-get install --reinstall nvidia-304,重启依然无法进入桌面

這個只是安裝程序
還有 啟用/設定/阻擋開源驅動 等等 需要在圖形界面 才能自動完成
否則必須手動一個一個進行
意思是 先想辦法 登入桌面

真的沒辦法 再從 tty1 ～ tty2 手動補救

[polau]

还有进入桌面的办法吗？

[polau]

在tty1里，
sudo apt-get purge nvidia-304*
sudo reboot

开机是按F11或者esc进入GRUB界面，按e 编辑启动项
在linux行尾添加 nouveau.modeset=0
ctrl+x 启动
顺利进入桌面。
接下来怎么解决启动的问题？

[poloshiao]

顺利进入桌面。

1. 恭喜你
在還沒完全安裝/啟用/設定顯卡驅動以前 都需要使用這個有效的方法 登入桌面
等到完全安裝/啟用/設定顯卡驅動以後 才不需要加開機參數

接下来怎么解决启动的问题？

2. 把下面指令 複製 貼進終端機 執行
2-1. uname -r
2-2. sudo lspci -knn
3-3. sudo lshw -numeric -class video
4-4. sudo ubuntu-drivers devices
4-5. sudo dkms status

3-1. 如果只有這兩項 表示 你安裝的 Linux kernel 有缺損
3-2. 等下再確認

4-6. sudo dpkg -l | grep linux-generic
4-7. sudo dpkg -l | grep linux-headers
4-8. sudo dpkg -l | grep linux-image
4-9. sudo cat /boot/grub/grub.cfg | grep menuentry | grep Ubuntu
4-10. sudo update-initramfs -u -k all
把結果直接 選取/複製 貼上來

[polau]

两台电脑，不知道怎么贴那么一大段的结果。

1. 目前沒有合適的驅動作用中

sudo ubuntu-drivers devices
driver : nvidia-304 - distro non-free recommended

2. 建議安裝 nvidia-304
2-1. 你已經會安裝了 所以安裝方法省略

3. lsmod | grep nouveau
看看 開源驅動 nouveau 有沒有成功被阻擋

4. lsmod | grep nvidia
看看 閉源開源驅動 nvidia 有沒有成功被載入

进入GRUB后，只有ubuntu, with linux 3.13.0-23-generic (recovery mode)选项
还有一个是ubuntu,linux 3.13.0.32-generic

4-6. sudo dpkg -l | grep linux-generic
4-7. sudo dpkg -l | grep linux-headers
4-8. sudo dpkg -l | grep linux-image

6. 你貼上來的 Linux kernel 版本 還看不出有何問題

帮我看看

闭源驱动nvidia 有没有成功载入？

1. 開源驅動 nouveau 仍然被載入
1-1. 安裝 nvidia-304 以後 重新開機前 需要把 nouveau 加入 載入黑名單
否則重開機 會阻擋 nvidia 發揮作用
1-2. 加入 載入黑名單 方法 參考
https://help.ubuntu.com/community/Binar ... ibernation
3. Blacklist the intel_agp module from being loaded by the kernel.
把 intel_agp 改為 nouveau

接下来呢？

2. 整個安裝完整程序 詳細參閱
https://help.ubuntu.com/community/Binar ... wto/Nvidia

3. 如果還有疑問 請再貼文

nvidia-304_304.128-0ubuntu0.0.1_amd64.deb 驱动已经包含 /etc/modprobe.d/nvidia-304_hybrid.conf 文件
其中含有 blacklist nouveau 相关内容
先检查究竟有没有 /etc/modprobe.d/nvidia-304_hybrid.conf 文件
再检查内容
标准内容为

代码： 全选

# This file was installed by nvidia-304
# Do not edit this file manually

blacklist nouveau
blacklist lbm-nouveau
alias nouveau off
alias lbm-nouveau off

具体命令 参考楼下

若 nouveau 仍处于载入状态 是否 nvidia-304 未正确安装？

[poloshiao]

是否 nvidia-304 未正确安装？

lsmod | grep nvidia

1. 沒有回應
表示沒有載入 nvidia 閉源驅動模組

2. sudo dpkg -l | grep nvidia-304
可以看看有沒有成功安裝 nvidia-304 套件

3. sudo ls -al /etc/modprobe.d | grep nvidia-304_hybrid.conf
可以看看有沒有安裝
/etc/modprobe.d/nvidia-304_hybrid.conf
3-1. 如果有
sudo cat /etc/modprobe.d/nvidia-304_hybrid.conf
可以看看有沒有
blacklist nouveau
blacklist lbm-nouveau
這兩行
