Comment 0 for bug 1449252

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 3.14.39-031439-generic #201504211206 SMP Tue Apr 21 11:09:35 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

With the following kernels, it doesn't:

Linux Martin-Laptop 3.15.0-031500-generic #201406131105 SMP Fri Jun 13 15:06:46 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
Linux Martin-Laptop 3.15.10-031510-generic #201408132333 SMP Thu Aug 14 03:35:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux
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-generic did not work either.

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...

With all kernels, I have a problem with shutting down the computer: when shutting down, at some (random?) point, the computer "freezes" and the screen remains on (with the lubuntu logo which is displayed during the shutdown process.)

Thanks for providing ubuntu!

Martin
