最近把工作电脑换成了机械革命无界 15XPro 暴风雪，在收货后小小折腾了一两天后，终于让他大部分的功能工作正常了。
可以参考这篇文章中的介绍安装来自德国一家公司维护的驱动。驱动安装好后，还可以安装类似鸡哥控制面板的 TUXEDO 控制面板，切换性能模式跟调整键盘背光 RGB：
笔记本内置屏幕在 60Hz 时会频繁随机掉帧，这个现象跟 VRR 有关，需要强制启用 VRR。
除此之外我还遇到了使用 Spectacle 截图时，外置显示器闪烁的问题，需要强制关闭外置显示器的 VRR。
当通过睡眠按键（Fn + F1）或者 systemctl suspend 进入睡眠状态时，系统会被立即唤醒，需要第二次尝试才能成功睡眠。
反复阅读 https://wiki.archlinux.org/title/Power_management 系列文章后，我在 deepseek-r1 的帮助下成功地找出了这个问题的根因。
创建一个 udev rule，禁用 PS/2 键盘的 Wakeup Trigger。
# sudoedit /etc/udev/rules.d/99-disable-keyboard-wakeup.rules
# Disable wakeup for PS/2 keyboard controller
ACTION=="add", SUBSYSTEM=="serio", KERNEL=="serio0", ATTR{power/wakeup}="disabled"然后重载 udev rules：
sudo udevadm control --reload-rules
sudo udevadm trigger重启系统后验证是否生效：
$ cat /sys/devices/platform/i8042/serio0/power/wakeup
disabled现在尝试睡眠，就不会被立即唤醒了。
首先安装 amd-debug-tools，运行 amd-s2idle test ，查看当前系统是否满足 s2idle 的要求：
$ amd-s2idle test

💻 MECHREVO WUJIE Series (STX\KRK)

💯 Your system does not meet s2idle prerequisites!
🗣️ Explanations for your system
🚦 Kernel is tainted
A tainted kernel may exhibit unpredictable bugs that are difficult for this script to characterize. If this is intended behavior run the tool with --force.
For more information on this failure see:https://gitlab.freedesktop.org/drm/amd/-/issues/3089可以看到这里提示我的 kernel 被 tainted 了，这是安装 mechrevo-drivers-dkms 引起的，可以忽略。
既然系统符合 s2idle 的要求，说明可能是某个设备在唤醒系统，deepseek 给出了接下来的排查思路，启用 PM 日志：
# Enable verbose PM debugging
echo 1 | sudo tee /sys/power/pm_print_times<br>echo 1 | sudo tee /sys/power/pm_debug_messages
# Now try to suspend again
systemctl suspend
# Check dmesg after resume
dmesg | grep -i "wake\|resume\|acpi"再次执行 systemctl suspend 复现问题后，可以在 dmesg 中看到下面的日志：

echo "disabled" | sudo tee /sys/devices/platform/i8042/serio0/power/wakeup重试睡眠后，系统果然安然入睡了～
进入 s2idle 睡眠后，一晚上大概会消耗 10% 左右的电量。
当启用 Firefox 的硬件加速后，播放视频会让 GPU 崩溃，丢失全部的显存内容。还好这个问题已经被 AMD 修复，升级到最新的内核即可。
机械革命提供了官方的色彩文件，但必须要在 Windows 下安装机械革命控制台才能下载（官方客服并不受理此类咨询）。加载了官方的色彩配置文件后，可以比较明显地缓解低亮度下对比度过低的问题。为了方面读到这篇文章的你，点击下面的链接就可以下载到这份色彩配置文件～
