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:
the cursor is not displayed on USB attached multiseat device Plugable UD-160-M.
Cursor came back on successful login. 

Version-Release number of selected component (if applicable):
gdm-3.8.4-6.el7
gnome-shell-3.8.4-5.el7
xorg-x11-server-Xorg-1.14.2-10.el7

How reproducible:
100%

Steps to Reproduce:
1. boot rhel7 machine
2. attache Plugable UD-160-M
3.

Actual results:
no cursor on gdm

Expected results:
there should be a cursor

Additional info:
on the login screen it seems that cursor is just invisible, it doesn't meant it is messing

screen-saver works as expected, I mean cursor is displayed

So:

1) gnome-shell (well mutter) is calling XDefineCursor at startup. 
2) gnome-settings-daemon is calling XFixesHideCursor() at startup and XFixesShowCursor() when the user moves the mouse plugged into the device
3) The cursor doesn't show up though.
4) If something calls XDefineCursor a second time (say hover over the password entry, or restart gnome-shell) then the cursor suddenly appears

It looks like an X server bug of some sort.  Since it only happens with pluggable devices, i wonder if it's some sort of hotplug race?

Moving to X server.

Does this build fix it?

Well it had better, because that change is included in RHEL7 now.
