I'm running chromium Version 91.0.4472.77 (Official Build) (64-bit) on a 6.9-mostly-current amd64. The machine has a 4k panel, so I added these to .Xdefaults:
Xft.dpi: 96 Xcursor.size: 96 Xcursor.theme: Adwaita I launch xmonad from xdm using .xsession, so no display environment. Almost everywhere (e.g. root window, emacs, xterm, firefox) the mouse cursor is a nice large arrow. Sadly, in chromium even with --force-device-scale-factor=2 the mouse cursor is imperceptibly tiny. I didn't find anything useful in chrome://settings and web searches are frustratingly useless. Anybody have a recipe? Thanks Greg
