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 v4.20 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.

The issue started happening after the use of an pre-installed harddrive
(with 16.04/unity) which i'd put in another noetebook: hardware change
from a asus P55 to a X55U. After that i started the usual udate & upgrade.

Last notice: i tried out to install a second (mate) desktop environment
... and to my suprise the brightness-function worked (16.04.5). Even the
FN+F5/F6 procedure works during the boot-procedure and stayed till the
restart (with unity) - changes are not possible in that case.

I'll try out your method and see/report what will happen ...

Thank you,

it works with MATE as it should, unlikely not with the official version
(18.04 LTS)
