Description Bojan Smojver 2013-06-27 01:02:33 UTC
Description of problem:
Occasionally, when I logout from Gnome, gdm fails to start the login screen (i.e. there is no Xorg running at all). Black screen and cursor in the upper left corner are the only things on the screen. Logging in as root on another console and doing "init 3; init5; exit" - yeah, I'm old :-) - does start it again.

Version-Release number of selected component (if applicable):
gdm-3.8.3-1.fc19.x86_64

How reproducible:
Sometimes.

Steps to Reproduce:
1. Logout from Gnome.
2. Wait for gdm login screen to appear.

Actual results:
Sometimes gdm does not show login screen after logout.

Expected results:
This worked reliably in F-18.

Additional info:
ThinkPad T510, Intel graphics. kernel-3.9.6-301.fc19.x86_64

Comment 1 George Walsh 2014-02-15 22:33:04 UTC
Our experience with this is is consistent rather than 'sometimes'.
gdm-3.10.0.1-1.fc20.x86_64
kernel-3.12.10-300.fc20.x86_64
gnome-shell-3.10.3-4.fc20.x86_64
kmod-nvidia-331.38-5.fc20.3.x86_64
xorg-x11-drv-nvidia-331.38-1,fc20.x86_64

... and the process before the proprietary driver was installed remains the same as after the nvidia install

This is what happens after the user requests (and confirms) logout:

1.  gdm login screen appears for less than 2 seconds.
2.  "HDMI no signal" block appears on a black screen

The operator now must enter [ESC] to display the gdm login screen (which will time out in 8 seconds so he has to be quick about selecting a new user!)

Comment 2 Fedora End Of Life 2015-01-09 18:33:15 UTC
This message is a notice that Fedora 19 is now at end of life. Fedora 
has stopped maintaining and issuing updates for Fedora 19. It is 
Fedora's policy to close all bug reports from releases that are no 
longer maintained. Approximately 4 (four) weeks from now this bug will
be closed as EOL if it remains open with a Fedora 'version' of '19'.

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 19 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.

Comment 3 Fedora End Of Life 2015-02-17 15:42:56 UTC
Fedora 19 changed to end-of-life (EOL) status on 2015-01-06. Fedora 19 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.
