I have the cause of this figured out I think. It camae from having multiple lines in /etc/passwd and /etc/group that had different names but the same uid or gid. This came about due to merging the new /etc/passwd and /etc/group from the new install with the list from a previous install. Fedora now forces creation of an account on install with no clear way to avoid, and the account created in the F24 install had the same uid and private gid as the one copied from my old F23 install. (At least on traditional UNIX multiple accounts with different names but the same UID was an occasional practice. I saw it used on IRIX for example to give multiple users root access via their own root accounts, all with uid 0.) This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '24'. 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 24 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. Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed. |
Created attachment 1177811 [details] gdm debug log Description of problem: GDM seems to start but gets stuck and doesn't actually take control of the display leading to a failure to properly boot Version-Release number of selected component (if applicable): gdm-3.20.1-3.fc24 How reproducible: Always (on my system, after but not including the first boot when installing Fedora 24) Steps to Reproduce: 1. Boot 2. Wait forever for a graphical login. 3. Via single user mode or a different console it is possible to troubleshoot. Actual results: No graphical login screen Expected results: Graphical login screen. Additional info: This is from a fresh F24 install. The original boot after installation worked fine, additional boots (after installing additional packages/updates/etc) did not. By uninstalling Plymouth and pressing <esc> in early startup, it is possible after the gdm failure to ctrl-alt-f2 over, do a text login and startx to get the graphical system working. Both Gnome and XFCE seem to work fine. setting WaylandEnable=false in /etc/gdm/custom.conf doesn't seem to help GDM doesn't seem to ever get to the point of opening the X-server -- /var/log/Xorg.0.log doesn't get touched. 'ps' shows both gdm itself and a gdm-session-worker systemctl status gdm.service shows gdm as running.
