关于上次升完级USB键盘鼠标不能用。用了几位达人的方法还是不能解决

[iphonewifi]

我原来安装的是ubuntu9.1昨天升级到10.04lts但升级过程中，碰到断电。我用dpkg --configure -a修复了一下然后把又用apt-get dist-upgrade重新升了一次。可以进系统了。但出现几个怪问题
第一就是我用的是USB键盘鼠标，但每次到登录窗口的时候其中一个设备就要罢工。从重新插到前置USB就好了。如果重新启动不拨掉前置USB中的设备，到登录界面两个设备全部不能用。
第二就是进入系统后用ctrl+alt+f1或者f2不能进入终端马上死机
第三就是进入系统每次都要提示一次系统崩溃报告。
在系统日志有些错误我贴出来请各位达人帮忙看一下。

现在我已经删除了所有配置文件但还是老毛病，我是删除完后没有重新启动。用apt-get dist-upgrade重新升了一次这样操作对不对，还有就是我没有在firefox操作界面里面备份书签，但用tar备份了所有文件，我想知道火狐的书签是放在那个文件夹里我覆盖现在的文件夹能不能找回书签？系统现在老是提示崩溃报告，输完密码后在系统日志里面又不知道到底是什么东西引起系统崩溃？拜托各位达人能给帮我解决
