I got a new laptop with a much higher screen resolution than I've ever had, 2560x1440 pixels. I'm using i3 window manager, and Arch linux current xterm (version 386-1, but that might be just the package version).
The xterm fonts and mount pointer (not the text cursor, not the X11 default cursor, the xterm mouse pointer) are way too small, verging on invisible.
I had to run up the xterm font size, and I got the X11 default mouse pointer bigger with an X resource. For the life of me, I can't make the xterm mouse pointer bigger. When I mouse over any xterm window, the mouse pointer goes from a large arrow to a tiny, tiny arrow.
How do I change xterm's mouse pointer size?
Just to for reference, here are my current X resources relating to this:
Note that I resized the default X11 mouse pointer with Xcursor.size, but this doesn't affect the xterm mouse pointer: it uses a different one, somehow.
Leaving XTerm*pointerShape to default makes it a microscopic I-beam shape when mousing over a xterm window. I'm currently compensating for the tiny tiny on-screen mouse pointer by coloring it red, and giving it a red outline.
