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: https://access.redhat.com/ |
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 Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 32767 x 32767 DP1 disconnected (normal left inverted right x axis y axis) DP2 connected primary 1920x1200+1920+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 59.99 1600x1200 60.00 1680x1050 59.95 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 640x480 60.00 720x400 70.08 HDMI1 disconnected (normal left inverted right x axis y axis) HDMI2 disconnected (normal left inverted right x axis y axis) VGA1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 59.99 1600x1200 60.00 1680x1050 59.95 1280x1024 60.02 1280x960 60.00 1024x768 60.00 800x600 60.32 640x480 60.00 720x400 70.08 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.
