Having an odd issue with a specific clientkey, meta+shift+k - not working

[ad-on-is]

I have a strange issue with a specific clientkey that started happening recently. I use meta+shift+(j,i,k,l) to move a client window to a specific screen. This worked fine until now. But all of a sudden meta+shift+k stopped working and doesn't do anything. If I change the key to something else, like "h" then it works. But I need it to be on "k".

Here's my current config.

local modkey = "Mod4"
local altkey = "Mod1"

awful.util.clientkeys = awful.util.table.join(
    awful.key(
        { altkey, "Shift" }, "m", lain.util.magnify_client
     ), awful.key(
        { modkey }, "f", function( c )

            c.maximized = not c.maximized
            c:raise()
        end
     ), awful.key(
        { modkey, "Shift" }, "f", function( c )

            c.fullscreen = not c.fullscreen
            c:raise()
        end
     ), awful.key( { modkey }, "q", function( c ) c:kill() end ), awful.key(
        { modkey }, "d", function( c )
            awful.client.floating.toggle()
            awful.placement.centered( c )
        end
     ), awful.key( { "Control" }, "Return", function( c ) c:swap( awful.client.getmaster() ) end ),
        awful.key( { modkey }, "o", function() focus_client( 1 ) end ),
        awful.key( { modkey, altkey }, "o", function() awful.client.swap.byidx( 1 ) end ),
        awful.key( { modkey, "Shift" }, "o", function( c ) awful.client.swap.byidx( 1 ) end ), awful.key(
            { modkey, "Shift" }, "i", function( c )
                for s in screen do if s.outputs["DisplayPort-1"] ~= nil then c:move_to_screen( s ) end end
            end
         ), awful.key(
            { modkey, "Shift" }, "k", function( c )
                for s in screen do if s.outputs["DisplayPort-0"] ~= nil then c:move_to_screen( s ) end end
            end
         ), awful.key(
            { modkey, "Shift" }, "l", function( c )
                for s in screen do if s.outputs["HDMI-A-0"] ~= nil then c:move_to_screen( s ) end end
            end
         ), awful.key(
            { modkey, "Shift" }, "j", function( c )
                for s in screen do if s.outputs["DisplayPort-2"] ~= nil then c:move_to_screen( s ) end end
            end
         ), awful.key( { modkey }, "m", function( c ) c.minimized = true end )
 )

expected behaviour

• meta+shift+i move window to HDMI-A-0
• meta+shift+k move window to DisplayPort-0

actual behaviour

• meta+shift+i move window to HDMI-A-0
• meta+shift+k nothing!

What's strange is, if I invoke the key-combo with xdotool it works.

KEY=Super+Shift+k
xdotool keydown ${KEY}; xdotool key XF86LogGrabInfo; xdotool keyup ${KEY}

What am I missing here?

Do you have another software that could have that hotkey assigned? Recently one of mine stopped working because xfce assigned that to something and was eating the input.

@unai-ndz That what I was trying to find out with XF86LogGrabInfo and inspecting the logs (journalctl and /var/log/Xorg.0.log), but there doesn't seem anything else grabbing the input. Is there anything else I can do to inspect what's eating the input?

I'm also not running awesome through xfce or anything else.

[unai-ndz]

Can't think of anything else tbh.

Solved!

The issue was a combination of xmodmap, globalkeys and clientkeys.

I disabled all global keys, except for the awesome.restart key, and everything worked as expected. I pinpointed it down to a global key modkey+shift+5. Interestingly, on my custom keyboard, I've mapped "5" to "k", but on a separate layer. However, this did not explain the fact, that the key still didn't work on my regular keyboard.

Then I remembered, in xmodmap I've overwritten the key "k" to be also "5" when hitting the right_meta key. Therefore the global shortcut meta+shift+5 AND the client shortcut meta+shift+k didn't work at all.
