如何远程使用 i3wm

ifnk · 2022-07-22 08:12:46

我安装了 xrdp tigervnc
sudo pacman -S xrdp

然后 i3wm 所在机器退出桌面环境在 win10 下使用 mstsc 远程，方式选择 xvnc 就能连上了

但是连上后alacritty 起不来了，别的terminal 能起来，报错如下

$ alacritty
thread 'main' panicked at 'Failed to initialize any backend! Wayland status: NoCompositorListening X11 status: XOpenDisplayFailed', /build/.cargo/registry/src/github.com-1ecc6299db9ec823/winit-0.26.1/src/platform_impl/linux/mod.rs:619:9
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

接着我发现按键映射 xkeysnail 也不能用了

这两个软件对我很重要，经常要用，有办法解决么，还是说 xrdp 远程限制如此？

我也是必须选择 Xvnc 才能远程，但刚装 Arch 时默认的 Xorg 明明可以啊，其他发行版用 Xorg 也从来没出问题啊，我觉得 Xorg 速度快点……

我参考了这个代码片段，现在能用 xorg 的方式远程了，alacritty 也能打开了，但是 xkeysnail 不报错，但是不能用

就是我怎么让 mstsc 的输入也当成一个键盘来供 xkeysnail 使用呢？

xkeysnail 这是用 uinput 接口了啊。原理是读取输入设备的数据，然后通过 uinput 设备喂进去。问题是，走 VNC 的话，输入事件是直接发给 VNC 服务端的，服务端并不会通过某个输入设备来获取输入。

那有什么软件是可以捕获 xrdp 远程按键的呢？我试了下用 https://github.com/rbreaves/kinto , 他是基于 xkeysnail 的，但是我这里启动都启动不了
