I'm not sure what "Wayland does that out of the box" means; I ran 18.04 with Wayland since launch, it never gave me different scaling per monitor (not in the Gnome UI anyway).
Are you saying it would have worked had I used xrandr?
- vetinari 7y agoxrandr is X11 only; it is X11 extension, after all. Are you sure you were running Wayland? In Fedora under Wayland, you could pick a monitor and choose scaling for it in the setting applet.
- alias_neo 7y agoI'm sure so far as when I login I select "Ubuntu on Wayland" and when I search through the output of top for "wayland" it's there. I'm not sure how else I prove I'm running Wayland. The machine I'm sending this from now is still running 18.04 on "Wayland" and I cannot set the DPI independently for each monitor, if I select my external monitor and set 200% and click "Done", I get 200% on all displays.
- vetinari 7y agoYou don't have to prove anything (but informatively, the way to detect wayland session is to check for XDG_SESSION_TYPE env variable). Also, just for curiosity, what GPU are you using? It is quite possible that 18.04 has some bugs. I don't have 18.04 machine with hidpi monitor at hand, so I can't have a look myself, so I chalk it up that there is something weird happening.
- alias_neo 7y agoThanks for the tip. The XPS 15 that I've tested this most on has a 1050. I'm using the proprietary Nvidia driver. My XPS 13 is using Intel from an 8th gen i7.
