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.

Description of problem:
When resuming a Lenovo T440s in a Dock with 1 external Monitor, after it was used without the dock, the Monitor is not recognized

Version-Release number of selected component (if applicable):
gnome-shell-3.8.4-45.el7.x86_64
gnome-shell-3.14.4-26.el7.x86_64 (it also doe snot work in RHEL 7.2 Candidate)

How reproducible:
Every time after the Notebook was used without external Monitor

Steps to Reproduce:
1. use the Notebook inside the dock with the external Monitor connected (tested with Displayport and DVI)
2. suspend the Notebook
3. take it out of the dock
4. resume the Notebook and work with it
5. suspend the Notebook
6. dock the Notebook and resume

Actual results:
The external Monitor is not recognized.

Expected results:
Monitor should turn on and be set up as before

Additional info:
2 workarounds so far:
1. restart gnome-shell (Alt-F2 + r)
2. undock and dock the Notebook one more time (while it is running)

Duplicated/related to bug 1197677 ?

This is a kernel issue, see bug 1254126.

do we have a patched kernel already to test out on RHEL 7.1?

kernel issue was fixed, this is gnome shell's piece missing in bug 1219476

Is this still an issue?

This can be closed for now. If I see similar issues from an upgrade to 7.6, I will open a new bug.

Thanks
Oliver
