I'm sorry but I'm not sure I fully understand the instructions... I'm
really bad at computing :(

So just to make sure... I have to download this one:

linux-headers-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb

then install it with " sudo dpkg -i "

and that's it ?

Or do I have to install
linux-image-3.18.0-031800rc5-generic_3.18.0-031800rc5.201411162035_amd64.deb

as well ...?


I managed to change the brightness thanks to Xcaliber, but I'd like to fix
this problem anyway...


Thanks in advance,

Martin

[Bug 1393160] Re: Backlight control not working; but entries in /sys/class/backlight.. Vendor: American Megatrends Inc.. Version: 5.6.5

[Joseph Salisbury]

Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.18 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'.

If you are unable to test the mainline kernel, for example it will not boot, 
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as 
"Confirmed".


Thanks in advance.
