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 v4.19 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.

hello,

this issue happens in both cases. when i start a clean install from a usb key AND when i try to update it from command lines.

the only kernel series that works correctly on my laptop starts to the 4.9.0 (debian) and finish to 4.15.0-36-generic #39.

i tried to test the 4.19 using ukuu and the problem is still here. the only option that i has to solve this was to do a fresh install from the usb key ubuntu 18.04 with 4.15 kernel.

i´m at your disposal for every informations that you will need.

cordially

Does this still happen on an up-to-date system?
