Oli's questions

我在新安装的 Kubuntu 20.04.1 上安装了 Nvidia 450。

Prime Render Offload 在手动模式下工作__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia

但是nvidia-settings说不支持素数。因此，如下所示，我在 nvidia 窗口中没有主要条目。

所以我认为集成 GPU 和 nvidia GPU 之间的切换不会是自动的，并且“按需”不起作用。

怎么了 ？谢谢您的帮助。

我正在尝试将我的 Mobility Radeon HD 4650 与 Kubuntu 14.04 一起使用。我已经看到专有驱动程序不适用于 Kubuntu 14.04 和新内核，我必须使用免费的 radeon 驱动程序。这是我的笔记本电脑： http: //doc.ubuntu-fr.org/toshiba_satellite_p300-27z/

但我有两个问题：

• 安装后（使用“nomodeset”使安装工作；没有“nomodeset”它冻结），我的屏幕只能使用 à 1152x864 分辨率并且无法选择 1440x900，这适用于 12.04 和 fglrx 驱动程序。
• 我的笔记本电脑很热；专有司机并非如此

我尝试了更多的方法，但没有任何效果，所以我需要你的帮助。

谢谢
