xscreensaver locks the screen regardless of user activity. I type and move my mouse and my screen gets locked from xscreensaver on random. I assume that the watchdog timer, timeout timer, is not reset with every keystroke and every mouse movement! Thats the only explanation for this behaviour qlist -Iv xscreensaver x11-misc/xscreensaver-5.33 localhost roman # qlist -Iv i3 x11-misc/i3status-2.9 x11-proto/dri3proto-1.0 x11-wm/i3-4.10.2 localhost roman # qlist -Iv xorg-server x11-base/xorg-server-1.17.1-r1 localhost roman # qlist -Iv eudev sys-fs/eudev-3.1.2 More about in my forum post: https://forums.gentoo.org/viewtopic-t-1016950-highlight-.html Reproducible: Always
5.33 has some changes related as "Better detection of user activity on modern GNOME systems". Do you see the same with =x11-misc/xscreensaver-5.32?
