It looks like XCalc.ad and XCalc-color.ad are not installed into /etc/X11/app-defaults Reproducible: Always Steps to Reproduce: 1. "xcalc -rpn" shows black & white image since new XCalc-color resources are unavailable. Actual Results: After un-bzipping the xcalc tar ball & cd'ing into xcalc-1.0.2, I did: cp XCalc-color.ad /etc/X11/app-defaults/XCalc-color Expected Results: Colorful xcalc in RPN mode!
They're installed in /usr/share/X11/app-defaults. And just specifying the -rpn flag doesn't bring color, as the manpage says you have to change your own xresources file to have this... *customization: -color and use xrdb to reload. This is a strace output to show you it's search order. access("/etc/X11/C/app-defaults/XCalc", R_OK) = -1 ENOENT (No such file or directory) access("/etc/X11/app-defaults/XCalc", R_OK) = -1 ENOENT (No such file or directory) access("/etc/X11/C/app-defaults/XCalc", R_OK) = -1 ENOENT (No such file or directory) access("/etc/X11/app-defaults/XCalc", R_OK) = -1 ENOENT (No such file or directory) access("/usr/share/X11/C/app-defaults/XCalc", R_OK) = -1 ENOENT (No such file or directory) access("/usr/share/X11/app-defaults/XCalc", R_OK) = 0 stat64("/usr/share/X11/app-defaults/XCalc", {st_mode=S_IFREG|0644, st_size=19405, ...}) = 0 open("/usr/share/X11/app-defaults/XCalc", O_RDONLY) = 4 Re-open if there's still trouble.
