Hi all, I've had a very elusive and frustrating problem this week and don't know where to look anymore. Maybe one of you has an idea? :) Since 2016-09-04, i3wm freezes every once and a while; often after waking the screen (even if it wasn't locked), a few times also directly or a few minutes after logging in. I have not yet found a conclusive pattern. The freeze is complete; no reaction to mouse or keyboard activity, not even in the debug logs. However, I can interact with the focused window just fine (I obviously cannot change focus). i3 also doesn't react to IPC calls (tried with i3-msg). Up to now, I had sent SIGTERM to important programs that had been running and KILLed i3 (it doesn't react to SIGTERM, either). Today, in my frustration, I tried sending SIGCONT instead. To my surprise, i3 immediately sprung back to life. What I do not understand is that i3 hasn't been updated in a while, let alone since Sunday. FWIW, I am running the fork i3-gaps instead of i3, but that is very close to upstream and has been stable forever. I posted /var/log/pacman.log from the day when it started on my server [0]. Does anyone have any clue what could be causing this? Thanks, Bennett [0]: https://vps1.piater.name/commie/#dvm1K6lg -- GPG fingerprint: 871F 1047 7DB3 DDED 5FC4 47B2 26C7 E577 EF96 7808
