I am setting these environment variables: export XKB_DEFAULT_LAYOUT=us,cz export XKB_DEFAULT_OPTIONS=caps:swapescape,grp:shift_caps_toggle,grp_led:scroll However, after said upgrade, this configuration doesn't work properly in sway WM (IIRC, cannot exchange layout with SHIFT+CAPS and "CAPS - ESC swap" doesn't work as expected, either -- ESC will work as ordinary CAPS but not vice-versa, but at least double ESC has the effect of ordinary "ESC"). Currently, I am forced to stay at 2.23.
Is that still the case with xkeyboard-config-2.24-2 ? There was a bug in -1 that has been fixed since, see bug 1587998
Actually, updated the package yesterday only to be tested with a full reboot today -- and I can confirm the behaviour matches the expectations again. Thanks, Peter!
