Dear Maintainer,
I am experiencing unexpected behavior related to Wacom stylus and
touchscreen using Lenovo ThinkPad X220 Tablet.
* What led up to the situation?
When OS enters a stand by (sleep) mode, up-on returning from the
stand-by, wacom stylus and touch screen functionality no longer work. It
appears as of there is no touch screen or stylus available to a user as a input
method. This takes place on a Lenovo ThinkPad X220 tablet.
* What exactly did you do (or not do) that was effective (or
ineffective)?
To bring back wacom stylus and touch screen functionality, user has to
log out the current session and log back in to Gnome3 GUI.
Complete OS restart also brings back touch screen and stylus functionality.
* What was the outcome of this action?
Once I logg out the current Gnome3 session, and long back, touchscreen
and wacom stylus work just like expected.
* What outcome did you expect instead?
I would expect that touch-screen and wacom stylus work when system
resumes from stand-by / sleep mode with out needing to log out the users
account.
Note:
This issue is manifested only after tablets screen is closed and OS
enters a sleep/stand by mode.
Before OS enters the stand-by / sleep mode, the output of 'lsusb' shows
the wacom controller as expected:
$ lsusb
Bus 002 Device 003: ID 056a:00e6 Wacom Co., Ltd
...same after OS resumes, it still shows the wacom controller been
available, however there is no response from a touch screen AND wacom stylus.
It seems that isse may be related to Gnome3, but I do not know what
other steps I can take to diagnose it and if this is really Gnome3 related.
I am conformable with CLI and of there is any specific testing you may
need, please let me know the relevant commands and I will provide the output.
Thank you for your time and looking in to this.
Very happy Debian user :)
