This change was made by a bot.

Does it work before you upgrade your system (with older kernels)?

Yes it did, thanks for quick response.

So I assume that's an IdeaPad 520.

Would it be possible for you to test the latest upstream kernel to see
if the bug exists there as well? That kernel is available from:

https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3-rc1/

If it's still not working, please attach the dmesg output to this bug.

(And it will be great if you can tell us which kernel prior to 4.15.0-54.58 works for you.)

Please change the bug status back to confirm after you have finished this test.
Thanks.

For more information: https://wiki.ubuntu.com/Kernel/MainlineBuilds

Yes, it's an ideapad.
