Still sad because my Precision 5560 (same as XPS 9510) has this floaty trackpad bug on Ubuntu and Pop OS for whatever reason! (I haven’t tried any other distro). Much easier for me to swap to Linux on my laptop than my desktop because my laptop is just for Python, LaTeX, and MATLAB.
Dell even sells a 5560 with Ubuntu preinstalled, but they don’t make it available for users. But I have not for the life of me been able to get the track-pad bug to go away.
