wacom tablet not working after resume from suspend

[sam tygier]

after resuming from suspend to ram, the usb bamboo fun tablet does not function, pen movements do not move the cursor, click do not register, and the buttons do not work. if the tablet is disconnected and reconnected then it works again.

when i disconnect and reconnect i get the following in dmesg

Same problem here, up to date intrepid 64-bit, wacom intuos 3 using the new HAL method that incorporates pressure support.

Here is a quick workaround that may work (I haven't tried it)

sudo nano /etc/default/acpi-support

find the line that says MODULES=""

and add wacom between the two quotation marks. Restart (or restart just your acpi) to make the changes effective.

[zeimusu (james-kilfiger)]

Confirm this issue. Adding the line to acpi-support as suggested doesn't seem to make a difference.

[zeimusu (james-kilfiger)]

Workaround.

running
sudo modprobe -r wacom && sudo modprobe wacom

will restart the tablet. These lines (minus the sudo) can be added to
/usr/lib/pm-utils/sleep.d/75modules to restart the wacom tablet (put them inside the resume_modules() function). With this I was able to suspend to ram and resume, apparently successfully.

[sam tygier (samtygier)]

this is still an issue in karmic.

looks like the best way to fix is to create a file /etc/pm/config.d/50wacom containing
SUSPEND_MODULES="wacom"
eg
echo 'SUSPEND_MODULES="wacom"' | sudo tee /etc/pm/config.d/50wacom

maybe a file like this should ship in some package, though i am not sure which?

this is stil an issue today.

Hi sam,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

seems fixed from me in lucid.

[zeimusu (james-kilfiger)]

Not for me in Lucid.

With a fresh install the wacom tablet doesn't wake up after suspend to ram. It is possible to wake it manually by removing then re-inserting the wacom module with modprobe.

I will try Sam's suggestion.

[zeimusu (james-kilfiger)]

Sam's suggestion works on my lucid box.

Can this file be part of the xserver-xorg-input-wacom package?

[zeimusu (james-kilfiger)]

Assign to a wacom package

A patch titled "Input: wacom - switch mode upon system resume" is included upstream in the kernel's linux-next integration testing tree. This patch has also been cc'd to the maintainers of the stable kernels (2.6.33 and possibly 2.6.32).

Hi sam,

This bug was reported against an earlier version of Ubuntu, can you
test if it still occurs on Lucid?

Please note we also provide technical support for older versions of
Ubuntu, but not in the bug tracker. Instead, to raise the issue through
normal support channels, please see:

Lucid, please run the following command to refresh the report:

If you are not the original reporter, please file a new bug report, so
we can work with you as the original reporter instead (you can reference
bug 399520 in your report if you think it may be related):

@Bryce Harrington
its zeimusu who is still suffering. when i tested in lucid it was fixed for me.

[zeimusu (james-kilfiger)]

I'll create a new bug and dupe this to it.

This makes no sense. By what logic are newer bug reports ever making older ones their duplicates?

If I do the above the wacom tablet (intuos 3) does work after suspend, however logging out (top-right, log out) crashes the X server about 33% of the time. I'm attaching the Xorg log from one such crash. Sometimes it blanks the screen and I can watch the black screen flicker a bit while X tries to come up (as in the log) - other times a portion of the desktop wallpaper remains and I lose keyboard and mouse and must do a hard reset. I don't have access to another machine to attempt to log in via SSH, but I suspect I'd be able to based on HDD activity.

To reproduce:
1. Add the file as above
2. Plug in Intuos 3
3. Log in, log out

You may need to repeat step 3 up to four times, but it generally crashes on the second or third logout and sometimes the first.

[Chris Mohler (cr33dog)]

Sorry - I might be facing a separate bug. After removing the offending (or so I thought) file from /etc/pm/config.d I neglected to plug the wacom tablet back in while I was testing. So: without the 50_wacom file at all, logging out with the wacom tablet plugged in crashes X.

1. Plug in tablet
2. Log in, log out

At some point (usually the second or third log out, but sometimes the first), step 2 will either cause the X server to lock up immediately, forcing a hard reboot or the X server will fail to restart.

Unplugging the tablet allowed me to log in/out 10 times with no hiccups.

So I'm guessing this may be unrelated. File another bug? If so, what info should do you need?
