在linux3.4下安裝AMD顯卡驅動

linux3.4相對linux3.3x有了較大的效能提升，介面方面也更改較多。AMD顯卡驅動在linux3.4下無法正常安裝。

下面是安裝步驟：

1.sudo ./amd-driver-installer-12-4-x86.x86_64.run

會提示錯誤，不要管他，繼續以下步驟

2.修改/lib/modules/fglrx/build_mod/firegl_public.c

for_each_cpu_mask(p, cpu_possible_map) ---> for(p=0;p<2;p++)

如果你不是兩個CPU核心，相應修改2為你的核心數

3.cd /lib/modules/fglrx/build_mod, sh make.sh

4.安裝模組 /lib/modules/fglrx # ./make_install.sh

卸載驅動：/usr/share/ati/fglrx-uninstall.sh，如果提示檔案被修改，無法卸載，嘗試添加--force參數
