Kubuntu 15.10 开机故障

开机后长久停留在Logo界面，强制重启进入RecoverMode后，重新安装Nvidia显卡驱动后能正常进入，而重新启动后问题依旧。

英伟达对unix类操作系统的显卡驱动的开发向来还是重视的，其专有驱动遇到问题的时候不多，不像amd的显卡驱动，装上以后，悬停、扭曲、花屏和黑屏等等异常现象层出不穷。很久以前，在ubuntu+gnome2+wine+mysql+php+n卡的环境中，就能搭建出魔兽服务器，能同时容纳1000人在线游戏，从不宕机，几乎无瑕疵。开源显卡驱动分四个层次，nouveau是第三层，edge才是第四层，性能已经很强了。试试如下命令，看有没有效果：

代码:

sudo update-alternatives --display gl_conf
sudo update-alternatives --config gl_conf
sudo ldconfig
sudo update-initramfs -u
reboot

3D加速应该是没有疑问的，因为各种特效都是正常的，而且VC1解码用vdpau时的CPU占用只有不足6%。

除了重启需要重新安装驱动（我用的是官方的闭源包）而外，显卡性能真的没有任何异常。这个现象出现在ubuntu的某一次更新之后。我想这个应该无关显示卡驱动。

英伟达对unix类操作系统的显卡驱动的开发向来还是重视的，其专有驱动遇到问题的时候不多，不像amd的显卡驱动，装上以后，悬停、扭曲、花屏和黑屏等等异常现象层出不穷。很久以前，在ubuntu+gnome2+wine+mysql+php+n卡的环境中，就能搭建出魔兽服务器，能同时容纳1000人在线游戏，从不宕机，几乎无瑕疵。开源显卡驱动分四个层次，nouveau是第三层，edge才是第四层，性能已经很强了。试试如下命令，看有没有效果：

代码:

sudo update-alternatives --display gl_conf
sudo update-alternatives --config gl_conf
sudo ldconfig
sudo update-initramfs -u
reboot

3D加速应该是没有疑问的，因为各种特效都是正常的，而且VC1解码用vdpau时的CPU占用只有不足6%。

vc1解码器，确定吗？太老的词，不在这儿看到，都快不记得有这东西的存在了，库里早已不提供w32codecs或w64codecs的软件包。gstreamer或ffmpeg随便一个，就能解决几乎所有格式的音视频编解码，更何况ubuntu-restricted-extras将这两者基本装全？不提这个了，还是说说显卡驱动的事情。既然是wily 15.10，那内核应该更新到4.2了，对付最新驱动障碍不大，ppa上的版本已经到355，装上试试。
没有卸载n卡驱动的话，输入:

代码:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get dist-upgrade
reboot

已经卸载n卡驱动的话，输入：

代码:

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install nvidia-graphics-drivers-355
reboot

jmb363？grub没报错？偶尔想起来的，能不能把过程写出来分享分享？
