http://bugzilla.opensuse.org/show_bug.cgi?id=1142177 Bug ID: 1142177 Summary: Shared memory leak while PC is idle on the login screen with Dual-screen setup Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.1 Hardware: x86-64 OS: Linux Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: martin@renwanz.de QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Created attachment 811016 --> http://bugzilla.opensuse.org/attachment.cgi?id=811016&action=edit syslog, output of ipcs -m, ipcs -mp, ipcs -mt, and ps aux - packed as tgz I have OpenSUSE Leap 15.1 installed with KDE / plasmashell with latest (stable) versions available, relevant version numbers: xorg-x11-server-1.20.3-lp151.3.1.x86_64 sddm-0.18.0-lp151.2.2.x86_64 libQt5Core5-5.9.7-lp151.3.1.x86_64 libQt5Gui5-5.9.7-lp151.3.1.x86_64 plasma5-session-5.12.8-lp151.2.1.noarch I am using a dual-screen setup. Whenever you leave the login screen (SDDM login manager) idle for some time, the system starts consuming (shared) memory. It starts with ~23 shared memory segments, which steadly increase with time (see my attachments). A successful login or a restart of the display-manager (systemctl restart display-manager) "resets" the shared memory usage. After 18 hours of idling, 20 GB of my overall 32 GB Ram is used by these shared memory segments. Is the current X-Server still using shared memory transport ? That's where I would suspect the bug, although I believe this must be a special case - because even though I searched thoroughly, I couldn't find anything related... Let me know if I can post any more information which helps to pin down the problem. Cheers, Martin Renwanz -- You are receiving this mail because: You are on the CC list for the bug.
