目前到手一款新机器,准备测试一下性能
结果ubuntu 12.04.2 对该机器的CPU支持不好(主要是显示有问题, 集成显卡是肯定的)
CPU : N2807 几年年初才出的
问题是无法正确识别屏幕分辨率
我单独装了14.04 分辨率能够正常识别
因为定制工作特别多, 所以希望不要升级到14.04, 而是在12.04上升级驱动
我尝试 apt-get upgrade 装了好多东西, 在 lspci 里看 pci设备名字也变了
但是还是不识别
我也按照帖子:
http://askubuntu.com/questions/336527/h ... enablement
升级了Xorg的东西
还是不行
在askubuntu问也没有人回答
只能回老家问啦, 希望大家不吝赐教
有可能发错区是么, 我可以去另一个区发同样的帖子么?
