我有一台带有外接显示器的笔记本电脑，我想将外接显示器用作主要显示器。我也在用 dwm 运行 Debian。xrandr -q给了我这个：
Screen 0: minimum 320 x 200, current 3286 x 1080, maximum 8192 x 8192
LVDS1 connected 1366x768+1920+0 (normal left inverted right x axis y axis) 345mm x 194mm
1366x768 60.0*+ 50.0
VGA1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 509mm x 286mm
1920x1080 60.0*+
（为了简洁起见，我省略了一些其他决议）。我的 dwm config.h 文件有几个如下标记规则：
static const Rule rules[] = {
/* xprop(1):
* WM_CLASS(STRING) = instance, class
* WM_NAME(STRING) = title
*/
/* class instance title tags mask isfloating monitor */
{ "Chromium", NULL, NULL, 1, False, -1 },
{ "xxxterm", NULL, NULL, 1, False, -1 },
{ "Surf", NULL, NULL, 1, False, -1 },
{ "Iceweasel", NULL, NULL, 1 << 1, False, -1 },
{ "Vlc", NULL, NULL, 1 << 3, False, -1 },
};
我的 ~/.xinitrc 文件中有这个 xrandr 命令，可以在运行时正确配置监视器startx：
xrandr --output VGA1 --auto --output LVDS1 --auto --right-of VGA1
我希望每当我打开程序时都应用我的标记规则，并让该程序自动分配给具有焦点的监视器。我找到了一个红迪网帖子也就是说 -1 会执行此操作，但对于任何具有标记规则的程序，它们总是在我的笔记本电脑 (LVDS1) 上打开，而不是在外部显示器 (VGA1) 上打开。
对于没有标签规则的程序（例如 st），它们将在具有焦点的监视器/标签上打开。我尝试将监视器值更改为0或1，重建dwm并重新启动X，结果是相同的。
如何配置 dwm，以便具有标记规则的程序在具有焦点的监视器上的各自标记中打开？

答案1
默认的 dwm 行为是在具有焦点的监视器/屏幕上打开应用程序（无论是否有规则）。
要在当前聚焦的监视器的第三个标签上打开 Surf，规则为：
{ "Surf", NULL, NULL, 1 << 2, True, -1 },要在主显示器的第二个标签上打开 VLC，无论焦点在哪里，规则是：
{ "VLC", NULL, NULL, 1 << 1, True, 1 },如果您的规则不符合此行为，则您配置 dwm 的方式可能存在其他问题。粘贴整个内容config.h可能会有所帮助。
