我刚刚安装了 Ubuntu-Gnome 16.04，它运行起来异常热，在没有任何密集应用程序运行的情况下温度超过 60 摄氏度。在 Windows 中，当没有密集应用程序运行时，温度接近 50 摄氏度。过去，这种情况经常发生在我安装 nvidia 驱动程序之前，并且计算机使用的是英特尔集成显卡，但我已经安装了这些驱动程序，它似乎仍然运行得很热。这是我的 lspci 输出，如果它有帮助

请告知我任何可能有助于解决此问题的其他信息。提前致谢。
编辑：经过一番折腾，我发现当我拔掉笔记本电脑的电源线时，温度会大幅下降。Ubuntu 是否有人对输入电源处理不当？这可能吗？
答案1
因此，温度差异的原因是 Windows 中的 nvidia 驱动程序会根据计算机的运行情况自动在英特尔集成显卡和 nvidia 显卡之间切换。不幸的是，在 Linux 中似乎没有办法做到这一点（bumblebee 是一个粗略的解决方案）。但是，可以通过更改 prime 配置文件在 nvidia-x-server 设置下手动切换图形设备。
