Too long gdm session start
Last modified: 2016-12-15 15:38:16 EST
Created attachment 1092881 [details] gdm log with debug information Description of problem: After I select a user on the greeting screen and enter a password, sometimes the gnome session appears quickly (a few seconds), but sometimes it takes several minutes or tenths minutes. When it starts a long time, the only gdm-session-worker process hangs for minutes without any child processes running. I attached the debugging log with both cases of opening gnome session. At 22:56:55 the session appeared quickly. After I closed it, I tried to open the new session at 22:58:20, but it appeared only 23:03:29, ie 6 minutes later. I can see the next lines in the log: --------------------------------------------------------- ноя 11 22:58:20 oleg2.oleghome audit[9253]: USER_LOGIN pid=9253 uid=0 auid=1001 ses=5 subj=system_u:system_r:xdm_t:s0-s0:c0.c1023 msg='uid=1001 exe="/usr/libexec/gdm-session-worker" hostname=? addr=? terminal=? res=success' ноя 11 22:58:20 oleg2.oleghome gdm[7052]: GdmSession: Emitting 'session-opened' signal ноя 11 23:03:29 oleg2.oleghome /usr/libexec/gdm-x-session[7294]: gnome-session-binary[7312]: DEBUG(+): GsmPresence: setting idle: 1 ноя 11 23:03:29 oleg2.oleghome gdm[7052]: GdmSession: external connection closed ноя 11 23:03:29 oleg2.oleghome gdm[7052]: GdmManager: client disconnected ноя 11 23:03:29 oleg2.oleghome gdm[7052]: GdmManager: trying to open new session --------------------------------------------------------- Why the session does not start after at first attempt?

This message is a reminder that Fedora 23 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 23. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '23'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 23 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
