Wolfgang Bauer: comment 41: Good hint. I forgot that /var/run/numlock-on is needed by X. comment 42: Both fixed. We indeed don't have to handle empty string. Package with those 3 fixes is available in the same repository (see comment 40). Leap 15 builds are ready, Factory builds will take some time. (But binaries should be compatible.) I guess it is ready for submit to Factory now. I am still unsure whether behavior of Scroll Lock is a bug or standard behavior.
