Keyboard unresponsive after suspend Ubuntu 16.04 with touchscreen

[nacenteno]

Ubuntu 16.04 64 bit
Toshiba Satellite P55W-C with touchscreen
CPU: Intel® Core™ i7-5500U CPU @ 2.40GHz × 4
Video Card: Intel® HD Graphics 5500 (Broadwell GT2)
Display: 15.6” diagonal widescreen TruBrite ® TFT LCD display at 1920 x 1080
native resolution (FHD)

After suspend, several times the keyboard is unresponsive.

Touchscreen remain responsive all the time so I had to suspend again using the touchscreen and try again until keyboard is finally responsive.

Already tried with an edit to /etc/default/grub
Changed the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash atkbd.reset"

Then run update-grub, and reboot.

That did not fix the issue.

I have attached the output of ubuntu-bug linux, what other information is needed to fix the issue?

What do you suggest to solve the issue?

Thanks.

I took a look at the syslog and I see this error with suspend:
Feb 25 16:06:03 TSat-P55W-C systemd-sleep[4251]: /lib/systemd/system-sleep/wpasupplicant failed with error code 255.

Is it related to the issue?

Thanks.

Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem?

Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.10 kernel[0].

If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'.

If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'.

Once testing of the upstream kernel is complete, please mark this bug as "Confirmed".

Thanks in advance.

Hi Joseph,

I appreciate your help with this issue.

I got the laptop late on 2015 new and installed 16.04 removing the original OS (Win10).

The issue has been there since the very first start on Ubuntu 16.04 but Windows 10 never had issues.

As for the upstream kernel, I see several Kernels 4.10 and 4.10.1, sorry but your instruction is vague. I am not going to guess and install without a very specific target.

Is there other specific log of settings you need to see before trying any install?

Let me know.

Thanks.
