No video of the event yet, sorry!

HiDPI displays are all the rage now, It is not easy to get your Linux scaled correctly in the past. openSUSE Leap15 has pretty good HiDPI support these days, you can enable HiDPI support more easier than before. In this talk I will give a brief introduction of HiDPI and share the status of HiDPI support on openSUSE Leap15 and summarize how to tweak the scaling factors for YaST Installer, Grub2(on both Legacy and UEFI mode), GDM, GNOME Session, SDDM, KDE Plasma, other apps (on both X and Wayland), some known issues and the support of fractional scaling from a Desktop user's perspective.

Hopefully this talk will help some openSUSE users to get their life with a HiDPI screen more pleasant.
