sway cannot reposition displays, gives no indication of error
Please fill out the following:
-
Sway Version: 1.7
-
Debug Log:
- https://gist.github.com/ohthehugemanatee/e9d5eae4f7822487b54d6ff0cd0f2fe4
-
Configuration File: Also happens with default configuration.
-
Stack Trace: N/A
-
Description: Sway starts and adds a second display just fine. But adjusting the position of either display does nothing.
To reproduce:
- connect second display (DP-5)
- run
swaymsg output DP-5 pos 0 0 - observe no position change.
~
❯ swaymsg --raw output DP-5 position 0 0
[
{
"success": true
}
]
~
❯ echo $?
0
Trying to do the same through wdisplays says "the display server was not able to process your changes."
Kanshi tries to apply my previously-working config, and thinks applying is fine... but fails afterwards.:
Apr 26 12:49:26 alia kanshi[29478]: applying profile 'homeoffice'
Apr 26 12:49:26 alia kanshi[29478]: applying profile output 'eDP-1' on connected head 'eDP-1'
Apr 26 12:49:26 alia kanshi[29478]: applying profile output 'Samsung Electric Company C34H89x H1AK500000' on connected head 'DP-5'
Apr 26 12:49:26 alia kanshi[29478]: failed to apply configuration for profile 'homeoffice'
Sway debug stdout and stderr output give no indication that anything is wrong.
In case it's helpful:

There are failures around applying output configurations with disman+wlroots backend as well.

A second try succeeds. Is https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/2693 related to this problem? My current workaround is a patch for disman to exit without a coredump and systemd then restarts it.
@emersion sorry about that, updated the debug log accordingly. I logged in from gdb, and ran:

swaymsg and kanshi were both unable to reposition. I then tried the same with wdisplays, but of course no luck.
If it's relevant: I noticed that when my locking script turns off my eDP-1 display (with swaymsg output eDP-1 disable, I can't turn it back on again.
-
swaymsg output eDP-1 dpms onandswaymsg output eDP-1 enabledo nothing. - I can reproduce myself: if I
disableit, the output won't come back on unless I logout. - I can manually trigger
dpms offanddpms onagain with no problem.
Thank you for your help!
Does this help? https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3575

With that patch I no longer get "Atomic commit failed (pageflip): Device or resource busy" error during hotplug.
Updated to latest devel wlroots (including this patch) and I can't reproduce the issue anymore - except kanshi still fails to reposition. Closing this issue as resolved, and opening one over there. :)
Dammit, gotta reopen. This worked for my first test, but not afterwards.
swaymsg output DP-6 position 0 500
# observe display successfully repositioned.
swaymsg output DP-6 position 0 0
# observe display is not repositioned.
swaymsg output DP-6 disable
# observe display is successfully disabled
swaymsg output DP-6 enable
# display is not enabled.
Need more logs, perhaps?
I still have this problem. DRM log from 30 seconds with swaywm already open: https://gist.github.com/ohthehugemanatee/cd9fd600fd197b48796ac2f0f7e0a2a7 . I opened wdisplays and tried repositioning the external display.

The key error is [drm:drm_dp_mst_atomic_check [drm_display_helper]] [MST PORT:0000000042f3aa23] not enough VCPI slots in mst state 00000000b362d8ac (avail=63) . A duckduckgo search came up with kernel patches to various graphics drivers especially including intel, which adjust how we get and track available VCPI slots... so it is clearly a kernel level issue. The number of VCPI slots detected is insufficient for the desired resolution/refresh rate.
I don't know enough about the video subsystem to be sure, but to my understanding : wlroots and swaymsg -t get_outputs correctly report the available resolutions for the adapter/display, but does not filter by limitations like VCPI slots.
The workaround is to simply use the same resolution at a lower refresh rate.
I leave it to the maintainers to decide if this should be addressed, or closed as wontfix.
but does not filter by limitations like VCPI slots
wlroots can't do that, only the kernel would have enough info, and even then this depends on the number of connected outputs etc.
You can try WLR_DRM_NO_MODIFIERS=1 as a workaround, it sometimes help on Intel.
