我有一台装有 ubuntu 12.10 (64) 的 hp g6，当我全屏观看闪光灯或玩象棋等小型 ubuntu 游戏时，温度会升至 80-90 度，正常浏览温度为 64-70，我有双 gpu，我在这里和 ubuntu 论坛上阅读了很多帖子，现在我不知道该怎么做，我读过关于 vgaswitcheroo 的文章，但我无法安装或启用它，将 gpu 从催化剂更改为省电没有帮助，请有人提供建议。

确实以某种方式解决了它，现在的温度是 55-60 - 手动安装了来自 hp 网站的驱动程序：amd-driver-installer-catalyst-13.1-linux-x86.x86_64 + jupiter 带有按需供电选项希望这会对某些人有所帮助
