osu! on Linux is nothing new. It has been running fine under Wine for almost a decade already (the first guide on the osu! forums goes back to 2009)! Getting it to work perfectly, to meet my top player needs, is another story though.
Arch Linux is a very rich distribution. There are plenty of packages in the official repositories that will suit most needs, however sometimes it may lack of something. But most of the time, there’s a solution in the AUR!
Few weeks ago, I noticed I was getting “input jumps” on the tablet I was using, the GAOMON S56K. I’ve had been using this tablet since November~December 2016, when GAOMON contacted me to send me a free sample in exchange for a review (no matter the opinion I give, of course!). It was so great that I sticked with it, until issues arose.
