From 69847872bb1d3ac7dd259facb97934da66c27cc5 Mon Sep 17 00:00:00 2001 From: Guido Cella Date: Tue, 8 Sep 2020 10:28:29 +0200 Subject: fix multi monitors If you don't recalculate the monitor's geometry before arranging, clients get arranged in the first monitor. I don't understand why this fixes the bug since tile() uses m->w rather than m->m, nor why it needs to be recalculated after creating the monitor but sway does it too. Although not necessary to fix the bug I also made arrangelayer() do like sway again and recalculate usable_area instead of reusing m->m, since m->m seems to be incorrect until it gets recalculated shortly after in arrange(), so I suspect that leaving usable_area = m->m will cause issues under certain circumstances. Someone with a multi-monitor setup or better knowledge of Wayland may be able to figure out the cause of the bug. For now, this makes layer shell work. --- dwl.c | 6 +++++- 1 file changed, 5 insertions(+), 1 deletion(-) (limited to 'dwl.c') diff --git a/dwl.c b/dwl.c index bd7ea6c..c921fa9 100644 --- a/dwl.c +++ b/dwl.c @@ -463,6 +463,7 @@ applyrules(Client *c) void arrange(Monitor *m) { + m->m = *wlr_output_layout_get_box(output_layout, m->wlr_output); if (m->lt[m->sellt]->arrange) m->lt[m->sellt]->arrange(m); /* XXX recheck pointer focus here... or in resize()? */ @@ -549,7 +550,7 @@ arrangelayer(Monitor *m, struct wl_list *list, struct wlr_box *usable_area, bool void arrangelayers(Monitor *m) { - struct wlr_box usable_area = m->m; + struct wlr_box usable_area = { 0 }; uint32_t layers_above_shell[] = { ZWLR_LAYER_SHELL_V1_LAYER_OVERLAY, ZWLR_LAYER_SHELL_V1_LAYER_TOP, @@ -558,6 +559,9 @@ arrangelayers(Monitor *m) LayerSurface *layersurface; struct wlr_keyboard *kb = wlr_seat_get_keyboard(seat); + wlr_output_effective_resolution(m->wlr_output, + &usable_area.width, &usable_area.height); + // Arrange exclusive surfaces from top->bottom arrangelayer(m, &m->layers[ZWLR_LAYER_SHELL_V1_LAYER_OVERLAY], &usable_area, true); -- cgit v1.2.3
