我的笔记本电脑上的 xserver 有问题。安装了 Ubuntu 12.04.1。首先，我只能在终端模式下启动。当我尝试使用命令启动 xserver 时，startx它失败了。

看来我的 AMD/ATI 驱动程序有问题。可以修复吗？
谢谢。
答案1
尝试卸载 fglrx 驱动程序 （当前版本的 fglrx 不支持 ATI Radeon Xpress 1250 卡）。
sudo apt-get purge fgrlx
或
sudo apt-get purge fglrx-updates（发布后更新）
之后，确保radeon驱动程序已安装。OSS 包包括：xserver-xorg-video-radeon，libdrm-radeon1。
