This issue is not present on kernel 5.9.8-zen1-1-zen. I am only trying LTS to see if would mitigate a different bug I was having.

This issue also appears if you start sway using systemd.

emersion commented 3 years ago

Can you confirm you have a card in /dev/dri?

emersion commented 3 years ago

Side note, https://github.com/swaywm/wlroots/pull/2465 should improve the situation a little by timing out after 10s.

emersion commented 3 years ago

Btw, these aren't debug logs. Start Sway with sway -d >sway.log 2>&1. Also don't strip out things you think aren't important.

I haven't been able to check /dev/dri on LTS because I've needed to use the system. On zen I have this output:

emersion commented 3 years ago

Can you try swaywm/wlroots#2465?

yellowsquid commented 3 years ago

It'll probably be at least a day before I next have the chance, especially if I have to build from source. I'll let you know the result as soon as I can.

emersion commented 3 years ago

See https://github.com/swaywm/sway/wiki/Development-Setup#compiling-as-a-subproject

yellowsquid commented 3 years ago

Can you confirm you have a card in /dev/dri?

I had to quickly reboot, so I went into LTS, and this directory didn't even exist! I guess that means its a kernel problem then. I knew this device was new, but I didn't realise it was so new that driver support only appeared in the last few kernel releases.

In that case, I'd expect Sway to give an error instead of hang. I'll try the wlroots patch when I get the chance to see if it fails any faster.

yellowsquid commented 3 years ago

After cherry-picking those commits onto 0.12.0, I can confirm that sway no longer freezes. Instead, after 10 seconds, it exits (because the kernel itself cannot recognise my graphics card).

lovesegfault commented 3 years ago

I just finished building a new PC and have hit this too. I'm on kernel 5.11.5, sway 1.5.1, and my GPU is an RX 6800 XT.

When starting sway it freezes for about three minutes, until it finally starts up with no problems:

Notice in the timestamps how long it stays frozen for. @emersion Should I attempt the same patch or is this a new/different issue?

emersion commented 3 years ago

Please try Sway/wlroots master. Open a new issue if it doesn't work.

lovesegfault commented 3 years ago

It didn't work, will open an issue in the AM :)
