cursor size emacs installed through guix

Question

I have an Arch-linux system and I just installed guix. Using Guix, I installed emacs. When I use the pacman-installed emacs all is well but when I use the guix-installed emacs, the mouse cursor gets really small every time the mouse hover over the emacs window.

I have an hidpi screen which should be the cause but I don't know why the mouse does not recognize the dpi of the system when using guix-installed emacs.

• emacs version is 28.1 (same as the system-wide version of emacs)
• I use i3 wm

EDIT: I did the test and the problem does not happen when I use sway (Wayland wm) instead of i3. I guess this is a problem between Xorg and guix.

Answer 1

I'm on Debian and I have the same issue as you. I've tried the regular ways to increase cursor size like setting Xcursor.size in ~/.Xresources, but to no avail. Then, I realized that Guix set a XCURSOR_PATH. My fix was to set XCURSOR_PATH manuall in .xinitrc to both the path from Debian and Guix:

export XCURSOR_PATH=/usr/share/icons/:/home/munen/.guix-profile/share/icons
