[solved] X201 tablet not working in Mint 17 Cinnamon x64

[ralienpp]

This laptop has a screen that is sensitive to touch as well as a stylus. If I go to the Graphics tablet item in settings - it says there are no tablets detected. However, I used to run Linux Mint Olivia x64 with Cinnamon, and the tablet worked out of the box.


My feeling is that the OS is not detecting this device:

There is no wacom module loaded either, so maybe this is related to the issue.


Which troubleshooting steps are recommended?

The tablet is not listed there, but nor was it listed there in the past - it is not connected to USB, it uses another bus - thus I think `lsusb` should be used with a grain of salt here (-:

should actually work right away.
check synaptic (package manager) if this is installed:
-xserver-xorg-input-wacom
-libwacom2
-libwacom-common

[ralienpp]

All of them are present, I checked via synaptic, and this way too:

Code: Select all

dpkg -l | grep wacom
ii  libwacom-common                             0.8-1                                               all          Wacom model feature query library (common files)
ii  libwacom2:amd64                             0.8-1                                               amd64        Wacom model feature query library
ii  xserver-xorg-input-wacom                    1:0.23.0-0ubuntu2                                   amd64        X.Org X server -- Wacom input driver

[PatH57]

what happens when you try:

Code: Select all

sudo modprobe wacom

[ralienpp]

It loads the module, I see that by running lsmod again:

Code: Select all

lsmod | grep wacom
wacom                  62856  0 
wacom_w8001            12982  0 

The tablet still does not react to touch or the stylus; the "Graphics tablet" tool in "Settings" still says no tablets detected.

[PatH57]

just an idea, does it work if you boot from the installation media in live mod?
you may have to add the wacom mod

[ralienpp]

Having experimented a little bit - I discovered that it works after a fresh boot, but it doesn't work after resuming from a suspended state.

The reason I did not reveal that until now is because I was sleeping/waking the machine for several weeks now; your suggestion to try the liveCD made me go through a power cycle.

What is causing it?


-------------
Some digging brought me to this: https://bugs.launchpad.net/ubuntu/+sour ... omments/34


Solution:

Code: Select all

Step 1:
Since the wacom input is setup using udev, if you run the following command “udevadm trigger –action=change” the stylus should work immediately.

Step 2:
To automate Step 1 create a text file in “/etc/pm/sleep.d” and have its contents contain the following
------------------------------------------------------------
#!/bin/sh
# Fix to restart wacom drivers after suspend
case "${1}" in
    resume|thaw)
  udevadm trigger --action=change
  ;;
esac

------------------------------------------------------------

Don't forget to mark this file as executable.

I hope this helps other people too.

god I'm so glad, I was loosing hope.
This is a known issue and there seems to be a couple of wrokarounds.
