It’s been a long and frustrating road, but I have finally resolved the touchpad issues that have plagued me for seemingly forever in Linux. By installing libinput and using it in favor of the Synaptics touchpad driver, the touchpad sensitivity issues that have often plagued my sessions of heads-down programming have come to an end.
On the flip side, however, the latest kernel build for Dell/Ubuntu 16.04 has destroyed Bluetooth support on this laptop. Prior to this update, it was working flawlessly. I am looking at how to revert to an earlier kernel in hopes that I can get it back. Secure boot seems to be standing in my way.
The new 4k monitor I ordered should arrive tomorrow. I am wondering what kind of special hell awaits me when I try to get a multi-monitor setup going. I might have to fall back to good-ole' clamshell mode.
