Hi @NessaRNG

Which version of dotfiles are you using? I see it looks like the previous dotfiles (v3).

Well, actually HiDPI is a bit tricky, I'm currently working on a good way to set it up, but for rxvt-unicode (URxvt) itself, you can change it by changing the configuration as follows.

dotfiles/.Xresources

Lines 5 to 8 in 97a7f4f

	URxvt.font: xft:mplus Nerd Font Mono:size=11:autohint=true,\
	xft:Noto Color Emoji:size=9:antialias=false,\
	xft:Monospace:size=11:autohint=true,\
	xft:Unifont:size=11:autohint=true

Then for rofi. This is universally applied.

dotfiles/.config/rofi/config.rasi

Line 18 in 97a7f4f

dpi: 0;

Unfortunately for the tint2 panel itself it's possible to be relative, but the problem is that the padding is also relative so the shape is irregular at different DPIs. If you wish, change this line to scale relatively to specific DPI as a reference, just set it to 96. This also applies to every configuration, so change all the tint2 configurations.

dotfiles/.config/tint2/mechanical-vertical.artistic.tint2rc

Line 154 in 97a7f4f

scale_relative_to_dpi = 0

Now the problem is application layers such as GTK, actually quite easy. Well, GTK uses Xft (like the URxvt font backend we use), so it can be configured via X resource database (xrdb).

The following command displays the current GTK DPI information. Mine is 96 by default.

💲 gtk-query-settings dpi

                        gtk-xft-dpi: 98304

Then to set it, add the following line to ~/.Xresources to make it permanent.

Xft.dpi: 120

Reload if you want to apply it without logging out.

💲 xrdb ~/.Xresources

If you prefer xrandr, it can be set to start automatically by adding the xrandr command to ~/.xinitrc if using xinit, and ~/.xprofile for the display manager. For more information here and here.

For desktop notifications, dunst already respect DPI setting by default.

Scaling the tint2 panel relatively also breaks openbox margin rules.

okay it's worked thanks
