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 Wacom Cintiq Pro 13 does not show up when plugged in. This was reported by Ping from Wacom, quote:
"After RHEL 8 beta started the first time, I plugged Cintiq Pro 13 first.
The device is recognized from kernel. But, cursor doesn’t move. And, No
Tablet detected in “Wacom Tablet”!"
I have been unable to reproduce this with hid-recordings of a Cintiq Pro 16 and Ping states there may be user error (though where??). We need QE to confirm this first with a physical Wacom Cintiq Pro 13.
Filing for the gnome-control-center, we can clone it for other components where necessary.
Version-Release number of selected component (if applicable):
RHEL8-beta, the publicly released version.
How reproducible:
Start RHEL8, plug Cintiq in.
Start gnome-control-center, verify that the tablet is listed in the Wacom panel. Bring the stylus into proximity, verify that the stylus shows up.
Verify that the stylus works in general
Punting to fwupd, Jason from Wacom writes:
I've finally been able to reproduce the issues with the Cintiq Pro 13.
In my case, at least, they seem to be fallout from the fwupd issue we
reported to Richard (https://github.com/hughsie/fwupd/issues/882). As
soon as the fwupd program talks to the Cintiq Pro 13 the device goes
into a STALL state and is basically unusable. If G-C-C runs before
fwupd then the device will show up; otherwise it doesn't. The pen
stops working as soon as fwupd runs as well, which is probably why
there wasn't any response. The Intuos Pro 2 is immune to the fwupd
issue and so works fine.
Disabling the fwupd plugin seems to have fixed things (though its hard
to be sure since I was having trouble reproducing in the first place).
Hopefully Richard's fixes are all that are necessary.
Just for reference: Bug 1657623 which I could reproduce on the Intuos Pro I have may be related, but not sure.
