thankpad E420 ubuntu 双显卡配置

###首先卸载曾经的显卡驱动 sudo apt-get remove –purge fglrx fglrx-amdcccle fglrx-dev
###安装闭源前准备的库 sudo apt-get install build-essential cdbs fakeroot dh-make debhelper debconf libstdc++6 dkms libqtgui4 wget execstack libelfg0 dh-modaliases linux-headers-generic

###如果是64位ubuntu,安装32位库: sudo apt-get install ia32-libs

###然后下载最新催化剂驱动
wget http://www2.ati.com/drivers/linux/amd-driver-installer-catalyst-12.10-x86.x86_64.zip
unzip amd-driver-installer-catalyst-12.10-x86.x86_64.zip
chmod +x amd-driver-installer-catalyst-12.10-x86.x86_64.run

###创建deb安装包并安装
sudo sh ./amd-driver-installer-catalyst-12.10-x86.x86_64.run –buildpkg Ubuntu/precise
sudo dpkg -i fglrx*.deb

###生成配置文件:
sudo aticonfig –initial -f

###防止配置未生效: sudo aticonfig –input=/etc/X11/xorg.conf –tls=1

重启检查是否成功 fglrxinfo

以上来自Ubuntu Precise Installation Guide

实测后报错
X Error of failed request: BadRequest (invalid request code or no such operation)

有重新执行了一遍,删除了xorg.comf 文件 sudo apt-get install –reinstall libgl1-mesa-glx:i386 libgl1-mesa-dri:i386 xserver-xorg-core
sudo dpkg-reconfigure xserver-xorg

重启后成功了.
