Bug Description
I upgraded my (l)ubuntu to 15.04, which resulted in a non-detected touchpad, i.e., xinput does not list it. I then tried various mainline kernels, with the following results.
With the following kernels, the touchpad works:
Linux Martin-Laptop 3.13.0-49-generic #83-Ubuntu SMP Fri Apr 10 20:11:33 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Linux Martin-Laptop 3.14.39-
With the following kernels, it doesn't:
Linux Martin-Laptop 3.15.0-
Linux Martin-Laptop 3.15.10-
Linux Martin-Laptop 3.16.0-34-generic #47-Ubuntu SMP Fri Apr 10 18:02:58 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
Linux Martin-Laptop 3.19.0-15-generic #15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux
4.0.0-040000-
On the other hand, 3.19.0-15-generic #15-Ubuntu SMP Thu Apr 16 23:32:37 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux appears to be the first kernel with which screen brightness control works...
WORKAROUND: In the BIOS, change Touchpad option from Advanced to Basic.
