From 96de2b539c00992003664d0de225cc28c2fb9e54 Mon Sep 17 00:00:00 2001 From: Brian Ashworth Date: Fri, 15 Feb 2019 03:01:19 -0500 Subject: [PATCH] apply_output_config: dpms on before modeset On the DRM backend, if an output is dpms'd off and a different output is hotplugged, the CRTC for the output is reclaimed. When modesetting an output without a CRTC, a CRTC will not be given to an output that is not desired to be enabled. This splits setting the dpms state in apply_output_config. If the output should be dpms on, the it is enabled before attempting to modeset. Otherwise, it is dpms'd off after setting everything else. This also adds DPMS_ON to the default output configs. --- sway/config/output.c | 22 +++++++++------------- 1 file changed, 9 insertions(+), 13 deletions(-) diff --git a/sway/config/output.c b/sway/config/output.c index 970764b03..f1a06379b 100644 --- a/sway/config/output.c +++ b/sway/config/output.c @@ -199,6 +199,11 @@ bool apply_output_config(struct output_config *oc, struct sway_output *output) { return true; } + if (oc && oc->dpms_state == DPMS_ON) { + sway_log(SWAY_DEBUG, "Turning on screen"); + wlr_output_enable(wlr_output, true); + } + bool modeset_success; if (oc && oc->width > 0 && oc->height > 0) { sway_log(SWAY_DEBUG, "Set %s mode to %dx%d (%f GHz)", oc->name, oc->width, @@ -263,19 +268,9 @@ bool apply_output_config(struct output_config *oc, struct sway_output *output) { } } - if (oc) { - switch (oc->dpms_state) { - case DPMS_ON: - sway_log(SWAY_DEBUG, "Turning on screen"); - wlr_output_enable(wlr_output, true); - break; - case DPMS_OFF: - sway_log(SWAY_DEBUG, "Turning off screen"); - wlr_output_enable(wlr_output, false); - break; - case DPMS_IGNORE: - break; - } + if (oc && oc->dpms_state == DPMS_OFF) { + sway_log(SWAY_DEBUG, "Turning off screen"); + wlr_output_enable(wlr_output, false); } return true; @@ -294,6 +289,7 @@ static void default_output_config(struct output_config *oc, oc->x = oc->y = -1; oc->scale = 1; oc->transform = WL_OUTPUT_TRANSFORM_NORMAL; + oc->dpms_state = DPMS_ON; } static struct output_config *get_output_config(char *identifier,
