Awesome WM ignores input in non-us layout

Question

I've started using Awesome WM, and found annoying that it ignores input in "Run" widget (mod+R) when current layout is not US, say, RU. Also, it ignores and any input (mouse klicks, keyboard - even not layout-specific keys like Esc!) in its launcher/mainmenu and "clients list" and so on. I'm using Arch Linux, and ~/.xinitrc has following line:

setxkbmap -layout "us, ru" -option "grp:caps_toggle, grp_led:caps"

Awesome's rc.lua default config has neither layout, nor capslock-specific things, but I tried to isolate problem and removed capslock toggle option from my xinitrc. This didn't help at all.

xev output shows that only thing changes when I switch layout (with capslock) is 'state':

P.S.: I also wonder where to find key abbriveations for awesome (ex. Shift_R) and what exactly these Mod1, Mod2 etc mean.

UPD: It's mostly the same problem as described in this question, but author said only about capslock-toggling, not about default (Alt-Shift) toggle.

The bug is apparently in this https://bugs.archlinux.org/task/29123.

Answer 2

I'm duplicating a comment to the accepted answer here for better visibility.

A workaround is to edit file /usr/share/X11/xkb/compat/basic and remove or comment out the lines:

group 2 = AltGr;
group 3 = AltGr;
group 4 = AltGr;

as suggested here
