[Lenovo T420s] function keys and other things don't work after sleep

[Jeff Lane ]

As part of the Natty cert test on this system, I used the Sleep Key (Fn-F4) this successfully put the system in Suspend. After hitting hte power button to wake the machine, the screen was very dark. I tried using the brightness keys to change that, but found that they now do not function. I then tried the battery key (Fn-F3) and that was also non-functional.

The volume keys seem to be working, but anything requiring the Fn key fails after this sleep.

Also, I tried running Power Manager to brighten the screen and that too failed to do anything, so now the screen is stuck at a dim level.

[Ara Pulido (ara)]

Chris, can you have a look to this one, please?

[Chris Van Hoof (vanhoof)]

Colin -- Can you take a look at this one?

[Colin Ian King (colin-king)]

Hrm, debugging this is going to be tricky as it requires cycling S3 *and* interacting with the keyboard. Is there any way of getting the machine sent to me so I can investigate.

This bug seems like the GPEs are not being enabled, but I require hitting the keys and watching for SCIs and GPE events and this is not easy to do remotely.

[Colin Ian King (colin-king)]

@Jeff/Chris, any change of getting my hands on this H/W?

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

Retested with another T420s, hotkeys work after suspend. However, brightness keys do not work at all (fresh install and -updates). Canonical HW ID: 201103-7424

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

-proposed does not solved the issue. In every case the OSD message is shown, but not action is taken to raise or lower the brightness.

[Colin Ian King (colin-king)]

@Marc, any possibility of me getting the kit shipped to me so I can work on this bug?

[Colin Ian King (colin-king)]

@Any follow-up if I can get my hand on this kit to figure out why it's failing?

[Colin Ian King (colin-king)]

Please can you attach the output from the following:

sudo fwts --

and also on the post resume state where the keys don't work please run:

sudo fwts brightness -r brightness.log

and attach the brightness.log

Thanks

[Colin Ian King (colin-king)]

Sorry, typos, please ignore the above, and do:

Please can you attach the output from the following:

sudo fwts --dump

and also on the post resume state where the keys don't work please run:

sudo fwts brightness -r brightness.log

and attach the brightness.log

Thanks

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

Colin -- As per Van Hoof's request I'll be bring the hardware to the sprint next week. Also, the brightness buttons don't work before or after suspend.

[Colin Ian King (colin-king)]

@Marc, I'm confused - are these regressions? Can you see if we get the same failures with Maverick on this machine?

Thanks.

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

Colin -- The system was enabled on Maverick, and did pass the brightness key test. I don't know if there were fixes that didn't make it to the natty image or not.

[Chris Van Hoof (vanhoof)]

Going back through the 10.10 bugs I do not see a bug filed indicating that this was an issue.

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

I can load up the stock 10.10 on there and see what happens

[Robert Hooker (sarvatt)]

For the brightness problem, the nvidia proprietary driver requires an xorg.conf option to work (it shipped with this when it was enabled)

Section "Device"
        Identifier "Default Device"
        Option "RegistryDwords" "EnableBrightnessControl=1"
EndSection

[Marc Legris (maaarc-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount-deactivatedaccount)]

I can confirm that with the above option to xorg.conf brightness keys works in discrete graphics mode. Also, other Fn keys and hotkeys works after suspend resume (S3) cycle.

[Manoj Iyer (manjo)]

ooops I was logged in as Marc on this laptop... the above test was done by me on a T420s at the Platform Rally

[Colin Ian King (colin-king)]

@Manoj, if you are happy with this now working, do you want to close this bug?

[Ara Pulido (ara)]

How can we move this forward? Do we need to create a patch for this?

[Ara Pulido (ara)]

Why is this marked as Incomplete?

[Chris Van Hoof (vanhoof)]

@Sarvatt -- Is the workaround you outlined in Comment #21 something that could be a bit more automated?

[Ara Pulido (ara)]

Any updates on this bug? Is this fixed now? Robert?

[Robert Hooker (sarvatt)]

No this is not fixed, the only way to fix it to interact with the proprietary driver properly is via an xorg.conf option and we don't have the means to add arbitrary xorg.conf options to have it fixed in the distro. Comment #18 "The system was enabled on Maverick, and did pass the brightness key test." must refer to it passing with the image it shipped with which did contain the xorg.conf option. The good news is that Alberto is looking into extending jockey so we can maintain a list of machines that need this workaround and add it to xorg.conf automatically so it works out of the box (W510, W520 were also affected).

[Pavol Klačanský (pavolzetor-deactivatedaccount)]

I have got this on Intel and t500
