這個也是怪自己，最近因為 Windows VM 不知道為什麼速度變很慢，所以改用 Linux 跑 VM ，雖然 Linux 下 VM 速度比 Windows 快，但是整體的感覺還是慢．本來以為是我的 i5-9600k VM 表現不好，但是看著 CPU utilization 感覺還是怪

[Gentoo][ARM64] Compile qtwebengine fail
Posted by richliu
on 2021/03/23

If CPU number is too much, compile qtwebengine will fail, seems ninja compile issues.
it better to reduce CPU number under 8, batter number is 4 or 6.
just put MAKEOPTS=”-j 4″ on your /etc/portage/make.conf
It can be roll back after compile qtwebengine.
modify package.env can support special MAKEOPTS command on some packages.
ex:
echo "dev-qt/qtwebengine lowcpu.conf" | sudo tee -a /etc/portage/package.env
mkdir -p /etc/portage/env
echo "MAKEOPTS=\"-j4\"" | sudo tee /etc/portage/env/lowcpu.confref.

htop can support multiple columns in one screen, just press F2 enter setup mode, and change left column and right column to CPUs (1-4/8) [Bar] and CPUs (5-8/8) [Bar]
htoprc , put it on /etc/htoprc or ~/.config/htop/htoprc
# Beware! This file is rewritten by htop when settings are changed in the interface.
# The parser is also very primitive, and not human-friendly.

Windows 10 滑鼠會頓的問題 Thinkpad Docking

本來用 Microsoft Bluetooth mouse 滑一滑一直覺得滑鼠會頓，想說藍牙被干擾的問題吧，雖然小困擾但是也是不太在意
但是後來換了一隻有線的滑鼠，還是會這樣，這就有點奇怪了
找了一下可能是 Realtek FMAPP.exe 或是 Realtek audio service 的問題
改名 FMAPP.exe 和在 msconfig.exe -> Services 內 disable Realtek audio service 就可以
用了幾天看起來有改善，在這邊記錄一下
2015 年就有人發現了到現在 Realtek 還是沒改善啊
註：最後找半天發現都不是這些問題，而是我只要開啟雙螢幕就會，猜測可能是 Intel Graph 能力不夠或是驅動程式問題
Notebook 是 Thinkpad X1 ，螢幕是 Samsung 4K Monitor
2020/12/10 更新
看起來是 Thinkpad 配上 ThunderBolt docking 就有可能會發生
總結以下一些我覺得有用的方式
1) 接上 docking 時關掉內建螢幕
2) 發生時調整電源模式，例如 high -> balance ，然後再 balance -> high
3) reboot 會消失
4) Power mode 從 advance power saving 改回傳統的 s3 (較低可能性)
5) 關掉 SysMain (superfetch) (較低可能性)

應該是 Thinkpad Docking 的問題，用 Thinkpad Docking Mouse Freeze 下去找會有很多案例，要不然就不要用 Thinkpad Docking ，其他家的都沒問題，要不然就還是接到 Notebook 吧

這個問題 Google 出來這個 URL 的方法我不能用

This is not a detail guide to describe how to full install system, just figure out some important point. Even not for Gentoo newbie.
Most important handbook is Gentoo AMD64 installation guide.
There is some different between ARM64 and AMD64
