Experimental fractional scaling doesn't work - Ubuntu 19.04 + Regolight desktop #2

Hello, I love this spin add-on upon Ubuntu and everything works properly except the fractional display scaling. Right now I've just lowered the resolution which is fine anyway for my use, just wanted to let you know about this and would love to know why there might be a problem with this.

I followed this guide: https://www.linuxuprising.com/2019/04/how-to-enable-hidpi-fractional-scaling.html

Hi @Fourstepper ! I took a look at your link and the settings described seem specific to the Gnome window manager, Mutter. Because Regolith uses i3-gaps, those settings would not have an effect. However, I believe you can adjust the scaling by specifying your DPI via Xresources. For example, ~/.Xresources:

Xft.dpi: 100

Setting different values should result in different scaling factors. Please re-open the issue if this doesn't work for you.

When I was using plain i3-gaps, setting Xft.dpi in my ~/.Xresources worked perfectly. But, when I installed Regolith, it stopped working. I set the same DPI in ~/.Xresources and ~/.Xresources-regolith (180) and it did change the scaling of the i3 bar, but nothing else.

When I go into the gnome settings in Regolith ($mod+d) I can set the display scaling to be 100% or 200%. This does effect most apps (although not all, like Alacritty and Rofi) but there is no way to set it to be 150% or 175%, which is where I would like it. Setting xranr --dpi didn't do anything either.

Pretty much the same boat as @QuinnFreedman right now.

There may be some tips here: https://wiki.gnome.org/HowDoI/HiDpi and here https://wiki.archlinux.org/index.php/HiDPI#GNOME.

I think the biggest offender right now is st, which doesn't respect Gnome scaling at all and instead requires the font sized to be changed in the Xresources. For now I'm back to xterm/Gnome terminal.
