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.
Putting this fix into libwacom is not as reliable as would be expected from an enterprise distribution. While the mapping can be made to work it is a hidden side-effect of the GNOME implementation for tablets. When the mapping fails, it may overwrite any attempts by the users to change the mapping later. And any fix in libwacom would apply to the specific device only (Cintiq 22HD in this case) when the mapping issue is a larger problem seen by touchscreens on RHEL6.
Suggested workaround to be run by a user to ensure the tablet is mapped to a monitor when required:
First, run xinput list to identify the device to be mapped. The output will look approximately like this:
$> xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft® 2.4GHz Transceiver v9.0 id=10 [slave pointer (2)]
⎜ ↳ Microsoft Microsoft® 2.4GHz Transceiver v9.0 id=11 [slave pointer (2)]
⎜ ↳ Wacom Cintiq 22HDT Pen stylus id=13 [slave pointer (2)]
⎜ ↳ Wacom Cintiq 22HDT Pen eraser id=14 [slave pointer (2)]
⎜ ↳ Wacom Cintiq 22HDT Pen pad id=15 [slave pointer (2)]
⎜ ↳ Wacom Cintiq 22HDT Finger touch id=16 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Microsoft Microsoft® 2.4GHz Transceiver v9.0 id=9 [slave keyboard (3)]
↳ Yubico Yubico Yubikey II id=12 [slave keyboard (3)]
The device to map is the "Wacom Cintiq 22HDT Finger touch" device. Now run xrandr to identify the output name:
$> xrandr

VIRTUAL1 disconnected (normal left inverted right x axis y axis)
To map the Cintiq to output DP2, the following command should be run:
xinput map-to-output "Wacom Cintiq 22HDT Finger touch" "DP2"
This command can be adjusted for other tablets that require similar mapping. As the name and output stay the same for a device, this command can be re-used after reboots.
Until there is a desktop-integrated solution (see Bug 1392665) users are requested to run the above command to get the screen mapping as required.
Red Hat Enterprise Linux 6 is in the Production 3 Phase. During the Production 3 Phase, Critical impact Security Advisories (RHSAs) and selected Urgent Priority Bug Fix Advisories (RHBAs) may be released as they become available.
The official life cycle policy can be reviewed here:
http://redhat.com/rhel/lifecycle
This issue does not meet the inclusion criteria for the Production 3 Phase and will be marked as CLOSED/WONTFIX. If this remains a critical requirement, please contact Red Hat Customer Support to request a re-evaluation of the issue, citing a clear business justification. Note that a strong business justification will be required for re-evaluation. Red Hat Customer Support can be contacted via the Red Hat Customer Portal at the following URL:
