RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Jul 18 18:27:09 kapy-ntb-x220 init: prefdm main process ended, respawning

This basically means that:

/etc/X11/prefdm has something wrong inside, tracking /usr/sbin/gdm shows that import of /etc/profile fails with error code 2.

This is caused by bash completion enabled for subscription manager and gdm running in /bin/sh shell:

sh-4.1$ . /etc/bash_completion.d/subscription-manager
sh: `_subscription-manager_list': not a valid identifier
sh: `_subscription-manager_refresh': not a valid identifier

Removing /etc/bash_completion.d/subscription_manager fixes the gdm startup.
Comment 2 Bryan Kearney 2012-11-09 22:04:20 UTC 
how do I enable bash completion?
Comment 3 Bryan Kearney 2012-11-12 18:42:17 UTC 
I installed a 6.2 machine, and upgraded to 6.3 I was not able to reproduce. In addition, I took a RHEl 6.2 machine and then applied:

subscription-manager-0.99.19-1.el6.x86_64
subscription-manager-firstboot-0.99.19-1.el6.x86_64
subscription-manager-gnome-0.99.19-1.el6.x86_64


and rebooted. Was no able to reproduce.
Comment 4 Karel Piwko 2012-11-13 11:44:25 UTC 
Bryan, you need to install bash completion package.

yum install bash-completion

Obviously, without bash completion it works fine.
Comment 5 Bryan Kearney 2012-12-04 21:02:52 UTC 
are you using sh instead of bash?
Comment 6 Karel Piwko 2012-12-10 08:01:19 UTC 
Well, yes. But it is not my intention, /bin/sh instead of /bin/bash is used in GDM/Xorg start scripts.
Comment 7 Bryan Kearney 2012-12-12 20:45:53 UTC 
This is what I attempted in order to recreate the problem. Please let me know if this is different from your steps:

1) Install the GOLD copy of the RHEL 6.2.
2) Install the bash-completion from epel (1.3.5.el6) 
3) Install the subscripition-manager from 6.3 (0.99.19-1)
4) reboot

Given that 4 works, I assume I can not recreate it.

Comment 10 Bryan Kearney 2012-12-13 15:16:42 UTC 
Spoke with Karel, and we agreed that if the file can be sourced under sh then this bug would be fixed. The patch is submitted upstream at

commit 957f409233b8501fa05a1b460c94aaf489626caa
Author: Bryan Kearney <bkearney>
Date:   Thu Dec 13 09:43:25 2012 -0500

    841496: Do not use hyphens in bash completion files as these are invalid for identifiers in the sh shell.
Comment 12 Karel Piwko 2012-12-14 08:04:19 UTC 
Latest version of the file makes possible to reboot into graphical environment and bash completion works fine. Thanks for fixing that!
Comment 14 J.C. Molet 2012-12-18 20:08:50 UTC 
subscription-manager-1.1.16-1.el6.x86_64

Testing with the above version, I have not been able to reproduce this bug with bash-completion installed.  GDM starts as normal.

Marking VERIFIED.
