Refreshrate resets to default after `power off` & `power on` #8297

Open litoj opened 3 months ago

Please fill out the following:

Sway Version: 1.9
Debug Log:
- sway.log

Configuration File:

output eDP-1 mode 2560x1600@48Hz
bindsym t output eDP-1 power toggle
bindsym q exit

Description:
- when sway is started, the output is applied correctly, but when the config changes or the display is turned off and on (swayidle swaymsg power off/on) the refreshrate setting doesn't get applied again (it uses the default), but other settings like resolution and scaling do.
- I think sway needs to request the refreshrate always when turning the display on, not just on the first connection.

does this reproduce on master? i remember having a similarish bug that i remember maybe got fixed but lost track of it..

litoj commented 3 months ago

Haven't checked yet, will do and report back.

Unfortunately yes, the same thing happens with sway version 1.10-dev-c30c4519 (Aug 15 2024, branch 'master')

for me just reloading sway config also resets the refresh rate. on latest master

the refreshrate setting doesn't get applied again (it uses the default),

Doesn't your log say it does get applied again? ctrl+f for Hz and they're all 48 except the detected modes section 00:00:01.398 [INFO] [wlr] [backend/drm/drm.c:786] connector eDP-1: Modesetting with 2560x1600 @ 48.000 Hz

Edit: I can't reproduce this at all :(

Yes, that's actually the very core of the issue (I forgot to mention) - when the screen is turned back on, it prints info about the last uset setting that it thinks is also the current. And continues to report this as the current setting despite clearly running on defaults. I observed this with mpv (said system uses 48Hz) and https://fpstest.org/refresh-rate-test/ (reported 120Hz when actually testing the screen refreshrate)
