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 Mathieu Baudier 2012-08-11 05:58:16 UTC 
Description of problem:
Since update to from 6.2 to 6.3 there is no more configuration tool for the Wacom Stylus of my Thinkpad X220 Tablet.
Wacomcpl has disappeared (which was working fine before) but the new gnome-wacom-properties does not recognize the tablet.

Version-Release number of selected component (if applicable):
control-center.x86_64                     1:2.28.1-37.el6                  @base
xorg-x11-drv-wacom.x86_64                 0.13.0-6.el6                     @base

CentOS 6.3 x86_64
Kernel 2.6.32-279.2.1.el6.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Start gnome-wacom-properties
2.
3.
  
Actual results:
Tablet not detected

Expected results:
Similar functionalities as those that used to be provided by wacomcpl (calibrating, assigning buttons, etc.)

Comment 2 RHEL Program Management 2012-12-14 08:11:25 UTC 
This request was not resolved in time for the current release.
Red Hat invites you to ask your support representative to
propose this request, if still desired, for consideration in
the next release of Red Hat Enterprise Linux.
Comment 3 Peter Hutterer 2013-04-29 05:30:30 UTC 
This is a libwacom issue, the error messages using names with the appended "stylus", "eraser" tool identifier indicate the driver is working correctly.
Comment 4 Mathieu Baudier 2013-05-13 11:54:22 UTC 
So, is there a workaround?
Or can I build something locally in order to have the calibration tool?

Upstream patch to add ISDv4 90 to the libwacom list. You can copy the file into /usr/share/libwacom if you don't want to rebuild the stack.

weird though, the x220t the tablet's ID is 0xE6, not 0x90 (which is the fallback device) and I thought he 0xe6 tablet isn't supported yet.
Comment 6 Mathieu Baudier 2013-05-16 07:39:52 UTC 
I added the file on an up-to-date CentOS 6 but the tablet still isn't recognized.

[mbaudier@mostar ~]$ cat /usr/share/libwacom/isdv4-90.tablet 
# USB tablet PC models:  ASUS R1E and ASUS R1F
#
# stylus with one button and eraser
#
# Screen size 11.7 x 7.9; 13.3" diagonal

I still ge the same warnings:

Comment 7 Peter Hutterer 2013-05-20 10:02:19 UTC 
can I have an evemu description report for this device please? packages are available here:

http://people.redhat.com/~phuttere/rpms/evemu/

I'm still wondering why your tablet is a 0x90 tablet and not the 0xE6 that my x220t has (which is not currently supported in RHEL6)
Comment 8 Mathieu Baudier 2013-05-20 10:20:31 UTC 
Thanks for your efforts. 

This is a Lenonvo Thinkpad x220t, type 4299-32G.

Here is the evemu output :

Comment 10 Peter Hutterer 2013-05-20 10:43:27 UTC 
Mathieu: is this the multi-touch capable x220t? what were the specs to this model? I'm trying to understand why you have different hardware than I have here.
Comment 11 Mathieu Baudier 2013-05-20 11:21:41 UTC 
No, this is a pen-only x220t.

When I bought it one year ago, there were already some multi-touch x220t but it seemed to be that it was less supported on Linux, so I played it safe and took the older pen-only model.

Does it answer your question?

I'm happy to build and test on this hardware whatever you send to me.
(I'm coordinator for the Enterprise Linux GIS rpm repository, so I'm used to build/rebuild packages or source code.)
Comment 12 Peter Hutterer 2013-05-22 00:35:55 UTC 
please attach the output of udevadm info --export-db as well. thanks
Comment 13 Peter Hutterer 2013-05-22 01:39:16 UTC 
changing slightly misleading title, this tablet was never supported by wacom-gnome-properties, previous support was wacomcpl only.

Comment 15 Peter Hutterer 2013-05-23 02:50:32 UTC 
Please give this test build a try:

http://people.redhat.com/~phuttere/rpms/847427/

Just dropping the data file in wasn't enough, a change to the udev rules is also required to ensure the tablet is tagged and visible to libwacom.
Comment 16 Mathieu Baudier 2013-05-23 11:05:29 UTC 
It works!
I could calibrate the pen. 

The new interface is very nice and usable.
Comment 22 Peter Hutterer 2013-07-01 00:21:55 UTC 
MODIFIED

libwacom-0.5-5.el6 is available in brew
