Recovering a removed monitor fails

[brodi1]

Distro: Arch Linux Hyprland Version: AUR (-git | commit 670d6ce8f476cbdced7aa62e7d8c16a48bccf0d5) Config:

monitor=HDMI-A-3,1920x1080@60,0x0,1,mirror,eDP-1
monitor=,preferred,auto,1

Log: hyprland.log

Steps to reproduce

1. Use the config I used
2. Start hyprland with external monitor connected
3. Disconnect monitor cable
4. Reconnect monitor cable

Expected outcome

Mirror the screen after reconnecting

Noted outcome

After reconnecting the external monitor (HDMI-A-3) it stays black and the windows on the integrated one (eDP-1) go invisible...

Check with recent commits.

@vaxerski k so I tested both 0ffaa8d and 5530cf6 with the same results.

It improved a lot but the part of the bug that causes the windows to go invisible still is there....but it happens less often. While I did the testing I got it like 4-5 on average after disconnecting and connecting the cable. Atleast when it happens im able to disconnect and reconnect the cable and everything is normal again....not like in previous versions where I had to kill the Hyprland process.

I tried figure it out the cause but I can't find anything abnormal inside the logs imo... I'm not 100% sure but I got a feeling that it happens when switching very quickly from a workspace with a XWayland window to another workspace with a native Wayland application

[vaxerski]

the windows don't disappear for me, the monitor just switches to a different workspace. You sure they disappear?

[brodi1]

@vaxerski

You sure they disappear?

yup! I just see my wallpaper and when I'm switching workspaces I can see the current focused window title on my waybar. And the screen output on the second monitor is frozen

[vaxerski]

super odd. That was fixed for me with recent commits.

[vaxerski]

make sure you updated by verifying the hash with hyprctl version

[brodi1]

@vaxerski

[vaxerski]

alr. Odd.

[brodi1]

@vaxerski idk if this helps but here's a part of the log (I enabled time logging). The frame on the second monitor stopped at 17:26:54 hyprland.log

[vaxerski]

Nothing out of the ordinary. Possibly a driver bug?

[vaxerski]

Can't even see any logs related to connecting / disconnecting mons

[brodi1]

Nothing out of the ordinary. Possibly a driver bug?

I also thought about that....

Sometimes I get layersurface messages inside the logs right when the frame freezes idk if it's related... one of them was this one https://github.com/hyprwm/Hyprland/blob/31aa357c17ab670041695da3d8ba8586063bf5a6/src/events/Layers.cpp#L29 I also tried turning off blur completly

[brodi1]

So I tried using the same installation but on other hardware (same iGPU) no problems at all.... imma close this issue for now

welcome to another episode of "your system is haunted"
