我的台式机原来安装的
win10系统,跑起来嗖嗖的,硬件没有什么问题,自从使用Ｕ盘安装了Ubuntu14.04之后，进入Ubuntu就会出现各种各样的死机情况,写代码会卡,打字会卡,上个网也能卡。电脑卡的时候任何设备都不能使用,也不能ctrl+alt+F1跳转到tty。请问我要如何解决?是显卡驱动的事么？网上给了一些答案但是太不靠谱了。这个是我最近一次死机的日志,是按alt+table键的时候死机的,当时电脑只开了sublimetext编辑器和chrome(chrome里也没有视频和flash)。
打开 /var/log/syslog

从U盘启动运行看卡不卡
如果卡就是硬件驱动的问题 选15.10等较新的版本再试
如果不卡就是原来的win分区问题 可以选着重装 装的时候选择装到整个硬盘 覆盖掉运来的win
对LVM不了解的话安装时不用选LVM 不然由于系统安装到LVM中 后期不能从U盘升级或恢复这个系统
