不要说把 swrast_dri.so和 r600_dri.so 删了。没用。下面是删了的结果。

显卡驱动就没有装成功过…

我的是A卡。。
1.添加源sudo gedit /etc/pacman.conf
[catalyst]
SigLevel = Optional TrustAll
Server = http://mirror.rts-informatique.fr/archlinux-catalyst/repo/catalyst/$arch
Server = http://mirror.hactar.bz/Vi0L0/catalyst/$arch
Server = http://catalyst.wirephire.com/repo/catalyst/$arch
Server = http://70.239.162.206/catalyst-mirror/repo/catalyst/$arch
sudo pacman -Sy
catalyst-hook
catalyst-utils
catalyst-libgl
opencl-catalyst - 可选,OpenCL支持
lib32-catalyst-utils - 可选,64-bit系统上32-bit的OpenGL支持
lib32-catalyst-libgl - 可选,64-bit系统上32-bit的OpenGL支持
lib32-opencl-catalyst - 可选,64-bit系统上32-bit的OpenCL支持
pacman-key --lsign 653c3094 （KEY的导入）
2.装驱动。sudo pacman -S catalyst-hook catalyst-utils catalyst-libgl opencl-catalyst lib32-catalyst-utils lib32-catalyst-libgl lib32-opencl-catalyst mesa-demos
3.安装完毕后，要配置 X，让其使用Catalyst。要确保fglrx模块在启动阶段加载，而且要禁用kernel mode setting.
配置 Catalyst. 若只有一个显示器，运行:
# sudo aticonfig --initial -f
启动时加载模块
禁用radeon以防其自动加载. 在/etc/modprobe.d/modprobe.conf里禁用radeon,同时保证它不被/etc/modules-load.d/里的文件加载. 详见kernel modules#Blacklisting.
sudo gedit /etc/modprobe.d/modprobe.conf
添加
blacklist radeon
fglrx
接下来,使模块fglrx自动加载. 添加fglrx到/etc/modules-load.d/下已有的模块文件的新一行,或者创建一个新的模块文件并添加fglrx.
禁用KMS，我用的grub.别的不一样哦。sudo gedit /boot/grub/grub.cfg
添加GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
然后
sudo grub-mkconfig -o /boot/grub/grub.cfg
检查安装是否成功
重启电脑并登录, 运行下列命令可查看fglrx是否正确运行
$ lsmod | grep fglrx$ fglrxinfo
若两者均有输出, 安装成功。进行桌面环境并运行以下命令检查直接渲染模式是否启用:
$ glxinfo | grep direct
若显示"direct rendering: yes"，恭喜你，到位了!
注意: 对于glxgears,你也可以使用:
$ fgl_glxgears
来测试fglrx.
工具Catalyst-hook
Catalyst-hook 是一个 systemd 服务,它在系统关机或重启后重新构建fglrx模块(如果需要的话,比如内核升级后).
使用之前请保证 base-devel 组和 linux-headers 包(对应你的内核)已经安装.
只需激活catalyst-hook.service服务即可:
# systemctl enable catalyst-hook
# systemctl start catalyst-hook

是无法启动的问题吗
mv ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/lib/i386-linux-gnu/libgcc_s.so.1{,.disable}
mv ~/.local/share/Steam/ubuntu12_32/steam-runtime/i386/usr/lib/i386-linux-gnu/libstdc++.so.6{,.disable}
找到这样的解决办法

不要用steam自带的运行库，从源里单独安装。具体看英文版wiki。中文版已死

所以到底怎么装steam,wiki英文看不懂。

替换libstdc++.so.6，用系统自带的软连接
