我在笔记本电脑上安装了 Xbuntu，但有时运行速度非常慢。我怀疑我的 GPU 和 wifi NIC 驱动程序不正确，因为当我上网并尝试同时观看视频（使用 VLC）时，速度变得非常慢。在 Linux 加载之前，我的屏幕像素化程度达到 100%，然后一切正常。
另外，执行 sudo apt-get upgrade 时我收到以下警告
W: Possible missing firmware /lib/firmware/amdgpu/ip_discovery.bin for module amdgpu

我已经安装了 Xubuntu，并选择了小工具较少的选项。我将提供尽可能多的信息，以便你们能够提供帮助。

AMD E-240 processor (Brazos Zacate)
AMD Radeon HD 6310 (Wrestler) UMD version: Mesa 23.0.4-0ubuntu1~22.04.1)
It's my understanding that the CPU and GPU are combined into one chipset.

lspci -v 中的两件事 首先，GPU 驱动程序似乎没问题。但是，我在执行 apt-get upgrade 时仍然收到有关缺少固件的警告。
其次，我注意到 Wifi 是 RTL8188CE 802.11b/g/n WiFi 适配器（rev 01），但使用的驱动程序是内核驱动程序：rtl8192ce
那么，在哪里可以找到丢失的固件？我是否只需复制目录中的文件就可以了？如何确保我拥有 100% 正确的驱动程序，如果没有，如何安装正确的驱动程序。最后，还有什么会减慢我的笔记本电脑的速度？从全新安装开始就是这样。
提前感谢您的帮助！
