[Note: I translated menu items from French, so there maybe some little differences from the actual English wording]
Description of problem:
When the keyboard layout ancient greek (up to 1453) (mizuochi m17n) is chosen, "Display the keyboard layout" displays nothing.
Version-Release number of selected component (if applicable):
Fedora 28
How reproducible:
always
Steps to Reproduce:
1.If not already done, choose "ancient greek (up to 1453) (mizuochi m17n)" as input source (gnome-control-center region).
2.On the top right corner of the screen, in the input languages menu, choose ancient greek (up to 1453) (mizuochi m17n).
3.On the same menu, click on "display keyboard layout".
Actual results:
nothing happens
Expected results:
"Ancient greek (up to 1453) (mizuochi m17n)" keyboard layout should be displayed.
Additional info:
+ If ps is then launched in a command line, gkbd-keyboard-display doesn't show up, as it does for other keyboard layout displays).
+ It seems that the former "ancient greek, polytonic" layout disappeared in Fedora 28.
"Show Keyboard Layout" is a known bug since long time.
$ rpm -qf /usr/bin/gkbd-keyboard-display
libgnomekbd-3.26.0-6.fc29.x86_64
Moving to libgnomekbd component.
