When using evdev support the XKB keymap name (with variant) for Dvorak users will be e.g. "US (Dvorak)". The Dvorak layouts are not described in /usr/share/X11/xkb/rules/evdev.xml, so these are not added to ply-keymap-metadata.h / keymap-render.png . For the console-keymap case dvorak is handled specially in: keymap-render.py:normalize_keymaps() ply-keymap-icon.c:ply_keymap_normalize_keymap() mapping all keymap-names with a lowercase dvorak in there to "dvorak", change this special handling to be case-insensitive so that it also works for the xkb-keymap case. Note the keymap-render.py change really is a no-op since keymap-render.py only calls normalize_keymaps() on console-keymaps which are always lower-case. normalize_keymaps() should still be updated though to keep the 2 functions in sync.
