Created attachment 337035 [details] journalctl -b this is the journalctl -b after gnome-shell freeze on dual monitor
You seem to be using a few gnome-shell extensions. Can you try disabling them and check if this still happens?
Created attachment 337125 [details] journalctl -b without shell extension
Without shell extensions I have the same problem
Any news for this?
I don't see anything evidently wrong. Are there any specific steps on your part that lead to the freeze? Does it not happen with a single monitor? Does the mouse pointer still move when it freezes?
i'm logged in to Gnome Session Wayland with single Monitor and everything working ok, then attach second monitor and the session still working for a few minute, after about 1 minute the mouse freeze, the keyboard not respond but Caps Lock led still work, the shell freeze all windows on all monitor. I tried to connect Monitor before start Gnome Session Wayland but i have the same problem. I tried with Weston Compositor with two Monitor and all working fine. This error is not present on gnome shell 3.20.
I can confirm this bug with a different hardware (Intel haswell). Nothing in the logs, SSH working, freeze only when there's more than 1 monitor. The freeze sometimes happens after a minute, sometimes after a couple of hours. I'm trying to find reliable steps to reproduce. I don't remember having this problem with 3.20 (but I only used it a few hours with Wayland). I use a rotated screen, don't know if it's related.
The problem appears with 4 different computers here, 2 distributions (Arch and Gentoo), Intel and AMD GPUs, 3 screens each (rotated or not).
How could we provide more info on this bug? SSH is working, I can kill the gnome session and everything works fine after that, but I lose my session of course. There's nothing interesting in the logs, and I really don't know how I can know what's going on. I can use my computer for days on Wayland with one monitor, no problem. No problem either with X and 3 screens. I've no idea about how to reproduce the bug in a reliable way :/. It sometimes happen after a couple of minutes, sometimes after hours. Everything is frozen on the screen, the mouse and the keyboard don't work (including the ctrl-alt-F1/7 shortcuts to reach a TTY).
