Monitor disconnections not detected

aarobc commented 3 years ago

Maybe this is a misunderstanding on my part, but when I shut off a monitor kanshi doesn't detect it as a change. A similar setup would function fine on autorandr with i3.

current setup:

sway-git
kanshi (from AUR)

profile dual {
    output DP-3 mode 3840x2160 position 0,0
    output DP-2 mode 2560x1440@143.856Hz position 3840,0
}

profile 4k {
    output DP-3 mode 3840x2160 position 0,0
}

profile 2k {
    output DP-2 mode 2560x1440@143.856Hz position 0,0
}

Is this a wayland thing?

Can you grab a drm_info dump after turning off the monitor?

I have the same issue. drm_info shows both monitors as “connected” even if I switch off Connector 1.

├───Connectors
│   ├───Connector 0
│   │   ├───Object ID: 95

│   │   ├───Object ID: 104
│   │   ├───Type: DisplayPort
│   │   ├───Status: connected

Only if I unplug the cable, the status will switch to “disconnected”. Does that mean that this is a dirver issue?

Driver info from `drm_info`:
