HP 战66 AMD系列是农企在笔记本市场向INTEL发起反攻的产品,入手有小半年了,一直用的是默认的windows10操作系统。最经打算系统学习以下k8s,于是把计划把它升级一下。

战66本生支持双硬盘,双内存,有不错的扩展性。于是趁着内存条便宜,买了根8G 3200MHZ的kingston内存,掏出我多年多年未用的samsung硬盘全都安装上去。现在基本配置如下。

全程一路配置下来还算顺利。大致总结以下吧。

安装双系统

由于BIOS支持UEFI,装双系统轻松了很多。基本上网上的教程比较完备。推荐这一篇文章给大家。基本上不会出错

在ubuntu20.4下亮度调节失效

网上有好几种办法,其实与我的情况都不相符。但看内容大致上都是显卡问题引起的。因为显卡是集显,可以通过以下指令确认以下

lshw -c video
*-display                 
    description: VGA compatible controller
    product: Renoir
    vendor: Advanced Micro Devices, Inc. [AMD/ATI]
    physical id: 0
    bus info: pci@0000:05:00.0
    version: c2
    width: 64 bits
    clock: 33MHz
    capabilities: pm pciexpress msi msix vga_controller bus_master cap_list
    configuration: driver=amdgpu latency=0
    resources: irq:44 memory:d0000000-dfffffff memory:e0000000-e01fffff ioport:2000(size=256) memory:e0600000-e067ffff

在亮度调节未生效时, display被标识为(unclaim),也就是未识别。同时产看亮度调节文件目录,只用这个文件sys/class/backlight/acpi_video0/brightness,感觉到可能是因为CPU较新,可能驱动未更新。于是下载了最新的内核,内核下载页面在这里https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D

linux-headers-5.9.3-050903-generic_5.9.3-050903.202011011237_amd64.deb
linux-image-unsigned-5.9.3-050903-generic_5.9.3-050903.202011011237_amd64.deb
linux-modules-5.9.3-050903-generic_5.9.3-050903.202011011237_amd64.deb

然后运行dpkg linux*.deb,重启系统,遇到has invalid signature,别着急。修改BIOS中的secure boot, 将其关闭即可 重启后再查看 /sys/class/backlight/ 目录多了个 amdgpu_bl0目录,原来的apci_video0没有了。亮度调节一切正常。
