I had the same issue, followed David's instructions, but I still get a rapidly expanding syslog file when I lock the screen. I am running Ubuntu 18.04.02 with gnome shell 3.28.3, dual monitor and intel graphics.
Something I can see is that when locked the screens are first turned to black, then they go in sleep mode, and then they suddenly come back to life, without any input. The continue these steps cyclically. My interpretation is that the asynchronous sleep mode between the two screens triggers a change in resolution that wakes the screens up and so on. But I can't confirm that. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-shell in Ubuntu. https://bugs.launchpad.net/bugs/1772677 Title: gnome-shell filling up syslog with thousands/millions of entries with stack traces ending in osdWindow.js (lines 206/207 in bionic, lines 223/224 in cosmic) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-shell/+bug/1772677/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
