Apparently, it was working with 16.10 (4.8.0-46), although I had a different setup (GNOME desktop added on an official UBUNTU installation from DELL).
The problem started with Ubuntu Gnome 17.04 (4.10.0-19) and persisted with 4.10.0-20. About testing the upstream kernel, I am willing to try. I just need a few info/confirmations: - Should I install the "all" image? (http://kernel.ubuntu.com/~kernel- ppa/mainline/v4.11-rc8/linux- headers-4.11.0-041100rc8_4.11.0-041100rc8.201704232131_all.deb) - I suppose that the best way to test it and restore the original setup would be using a LVM snapshot, merging it back when finished, right? - What about grub? Will the new kernel be available as an entry in the grub menu, or should I do anything manually?
