http://bugzilla.opensuse.org/show_bug.cgi?id=1053373 Bug ID: 1053373 Summary: MIT-SHM extension does not work in Xvnc Classification: openSUSE Product: openSUSE Distribution Version: Leap 42.3 Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: X.Org Assignee: xorg-maintainer-bugs@forge.provo.novell.com Reporter: msrb@suse.com QA Contact: xorg-maintainer-bugs@forge.provo.novell.com Found By: --- Blocker: --- Application using MIT-SHM extension create the shm segments with 0600 permissions, which means X server must be running either under the same user, or under root to be able to access them. Xvnc that is started by xinetd/systemd runs under the "vnc" user (not root for safety and not a specific user, because Xvnc is started before any user is selected in a graphical login). So every attempt to use MIT-SHM fails. Some applications do not handle the failure gracefully (for example kdm). MIT-SHM extension should be disabled for Xvnc. -- You are receiving this mail because: You are on the CC list for the bug.
