请注意帖子末尾的三个更新。
原始问题
我使用该forcepae
选件在旧版Acer Travelmate 4500上安装了Lubuntu 14.04.1,并根据/ubuntu//a/515909/288322调整了upowerd.py 。在运行更新管理器直到据说系统是最新的之后,我遇到两个问题:无法访问USB记忆棒,并且笔记本计算机在关机期间挂起。
该问题可能以某种方式与更新包“ common library libudev”和“ / dev / and hotplug background process”有关:我一次选择了一个更新;当选择“公共库libudev”作为倒数第二个(我想选择“ / dev /和hotplug后台进程”作为倒数第二个)时,状态栏将显示更新Setting up udev (204-5ubuntu20.5)
。它说在此之前的几行Adding diversion of /bin/udevadm to /bin/udevadm.upgrade by fake-udev'
;这可能也很有趣。除此之外,通常是准备拆包,拆包,处理和设置“ libudev1:i386(204-5ubuntu20.5)”。我不得不杀死更新管理器,然后重新启动笔记本电脑。
现在,即重新开机后,我可以访问USB记忆棒和系统关机工作优秀(显示All processes ended within 1 seconds...
,有关NetworkManager的消息[471],Deactivating swap
并且Will now halt
然后,关闭。到目前为止好,但无线不工作;没有eth1列出iwconfig
。我重新启动,但是按描述继续运行(USB完美,关机完美,无无线)。在那个阶段,我在问题/ubuntu//中发布了描述。q / 521402/288322(即使我关闭了这个问题,也许这种描述可能会有所帮助。)
然后,我再次打开更新管理器,它会自动运行一些任务并显示消息,表明系统现在是最新的。没有更多可用的更新,即我尚未选择安装的“ / dev /和hotplug后台进程”必须已自动安装。USB和关机有效,无线无效。
然后,重新启动后,情况发生了变化:现在,我...
- ...无法访问任何USB记忆棒;
- ...系统挂起,
Killing all remaining processes ... [fail]
在NetworkManager上显示消息,Will now halt
但从未关闭; - ...无线eth1工作正常。
关于关机期间的挂起,我在一个关于Lubuntu的问题中描述了一个稍早的阶段(仍然有效,但细节可能有所更改):关机或重新启动均无效。
关于USB记忆棒,我读取了USB识别但不可用的信息?。在这里,类似信息:
luke@humboldt:~$ uname -a

输入两个USB设备(一个记忆棒和一个外部硬盘,它们在另一台计算机上都可以正常工作)后:

但是,在PCManFM中无法访问任何USB设备,也未在/ media / luke下列出。
在两个USB设备仍然连接的情况下,fdisk

我重新启动了笔记本电脑几次。问题仍然存在。使用Lubuntu 14.04.1实时CD时,可以直接访问所有设备。
这个问题可能与udev有关吗?因为在第一次更新失败后重新启动与再次重新运行更新管理器之间重新启动之间,我可以访问USB设备以及正确关闭系统。但是,wifi / eth1丢失了。我将整个系统日志放在https://www.dropbox.com/sh/b1ghdxsq1x1v7wv/AAD05PcvzIY33SpbcsXoK0QKa?dl=0上,以防万一。我还添加了kern.log,易/ history.log,易/ term.log,安装/系统日志,安装/调试和输出lspci -nn
和demidecode
。
还有评论说内核可能无法正确映射到sd *,请参阅USB识别但不可用?。
预先感谢您的提示!
