我使用 Linux Manjaro Gnome X11。我喜欢对鼠标按钮进行特殊设置，这是通过xinput.
为了使此设置在会话中保持不变，我编写了xinputin ~/.xprofile，实际上它在每个会话开始时都有效。
但是，它会在给定会话内经过一段时间后停止工作（不注销）。
~/.config/autostart/*.desktop可以使用Gnome 启动项 ( ) 来代替~/.xprofile。

是什么破坏了我的设置？如何使其在会话期间完全持久？
答案1
低级解决方案：我设置了一个无限循环的后台作业。
alba@mac2011-manjaro% cat ~/.xprofile
# This file is read at X11 start.
# In Fedora use ~/.config/autostart/*.desktop instead.
# # avoid spurious paste while scrolling
# # find the device number
# # repeat forever
while sleep 1
do xinput list|grep pointer|tail -1|grep -o 'id=[0-9]*'|grep -o '[0-9]*'|xargs -I{} xinput set-button-map {} 1 3 2
done&
这是无法完成的，crontab因为 cron 作业无法连接到 X 服务器（而且一分钟也太短了）。
