Lenovi X1 Carbon regularly has frozen lock- or dark screen after closing lid

[Pieter Smith]

I was running ubuntu 17.10 for months with no issues. After upgrading to 18.04, closing the lid regularly (but not always) results in either:
1. The display staying on with a frozen lock-screen, or
2. The display powered off, but the notebook still powered on.

In both cases the notebook does not respond. A five-second press of the power button to hard-reboot the computer is the only means of recovery.

After powering the notebook back on, there are no files in /var/crash.

O'h I forgot to mention it. After experiencing this problem, I tried a fresh install. This did not resolve the issue.

[Joseph Salisbury (jsalisbury)]

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 v4.17 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.

Please ignore the first question. You already indicated this is a regression.

[Ubuntu Kernel Bot (ubuntu-kernel-bot)]

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1775945

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

The issue started after upgrading from Ubuntu 17.10 to 18.04LTS. I did
not note the kernel version before upgrading, but it would have been the
default accomodating 17.10. I kept the notebook up to date, and I did
not have any reason to change to a non-default kernel.

I will try this and let you know what I find.

Will do if I no longer see the problem for a week.

Will do if the problem reproduces in a week.

Will do.

You too. Will get back to you on this.

After using the latest v4.17 kernel, I can confirm that the problem does
not appear to surface.

Hi Joseph,

What's next?

[Joseph Salisbury (jsalisbury)]

Can you see if the fix was already sent to upstream table by testing the latest upstream stable 4.15 kernel:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.15.18/

[Pieter Smith (smipi1)]

Hi Joseph,

I switched over to 4.15.18. Will keep an eye on it for the next two weeks to see if the problem resurfaces.

Thanks,
Pieter

[Pieter Smith (smipi1)]

Hi Joseph,

I've been on 4.15.18 upstream stable for three weeks now, and the problem seems to be gone. When will the Ubuntu kernel have the fixes incorporated so that I can I switch back from the upstream stable kernel?

Regards,
Pieter

[Joseph Salisbury (jsalisbury)]

Would it be possible for you to test the proposed kernel and post back if it resolves this bug?
See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

Thank you in advance!

[Pieter Smith (smipi1)]

This has been resolved for me. I have not been experiencing any lid closing related lockups for the last half a year.
