在 NixOS 上用 Solaar 設定羅技 Master 3S 拇指滾輪來切換前後分頁。
NixOS 上安裝 Solaar
安裝 solaar 並加上 udev rule 讓非 root 也能使用 (ref)
configuration.nix ：
environment.systemPackages = with pkgs; [
solaar
];
services.udev.extraRules = ''
# Allows non-root users to have raw access to Logitech devices.
# Allowing users to write to the device is potentially dangerous
# because they could perform firmware updates.
KERNEL=="uinput", SUBSYSTEM=="misc", TAG+="uaccess", OPTIONS+="static_node=uinput"
ACTION == "remove", GOTO="solaar_end"
SUBSYSTEM != "hidraw", GOTO="solaar_end"
# USB-connected Logitech receivers and devices
ATTRS{idVendor}=="046d", GOTO="solaar_apply"
# Lenovo nano receiver
ATTRS{idVendor}=="17ef", ATTRS{idProduct}=="6042", GOTO="solaar_apply"
# Bluetooth-connected Logitech devices
KERNELS == "0005:046D:*", GOTO="solaar_apply"
GOTO="solaar_end"
LABEL="solaar_apply"
# Allow any seated user to access the receiver.
# uaccess: modern ACL-enabled udev
TAG+="uaccess"
# Grant members of the "plugdev" group access to receiver (useful for SSH users)
#MODE="0660", GROUP="plugdev"
LABEL="solaar_end"
# vim: ft=udevrules
'';
之後 rebuild
Solaar 設定 MX Master 3S 拇指滾輪
MX Master 3S 設定打開 Thumb Wheel Direction 跟 Thumb Wheel Diversion：
設定 User-defined rules 做換頁：
在 KDE 設定啟動時執行 Solaar
到 KDE 的 System Settings => Autostart 加入 application Solaar，編輯 properties 到 Application tab 在 Arguments 加上 `--window=hide` 讓 Solaar 啟動的時候不會把視窗也打開 (ref)。
