ubuntu中编译新内核后nvidia-common出错

昨天我手动编译了新的内核，linux-kernel-2.6.28.4.编译后我的系统并没有出来什么大问题，可是今天我更新系统的时候出现了我以前没有遇到过的问题。代码附在后面。在网上并没有找到解决方法。于是自己来分析一下原因。我注意到，程序关键出错在执行到run-parts: executing /etc/kernel/postinst.d/nvidia-common时。而nvidia-common是N卡的驱动相关的软件包。而我自己的是A卡。我想这个跟我的系统应该没有多大关系。所以选择删除。
执行：
sudo apt-get purge nvidia-common
删除之后再继续安装刚才的软件。这次没有再报错顺利执行了。呵呵！好高兴，之后我再把nvidia-common重新装上。
