Hello,

same here with french keyboard and "Shift + Ctrl_L + 2".

(because on french keyboard, you have to press "Shift + 2" in order to get "2" key)

Linux Ubuntu 16.04 on VirtualBox

Host is Windows Seven

Hello,

My window manager uses the number keys to switch between tags (it's
"awesome"). I noticed that for a while, I was no longer able to move
a client to tag "2" (Mod4-Shift-2), while moving to other tags
worked fine. Also, I could still switch to tag "2" (Mod4-2), so it
was something about the shift key, I gathered.

Well, not so. Using xev, I discovered the following:

Entering "1" and "2" into the xev gives consistent results. Holding
down shift yields "!" and "@" as it should for a US keyboard.

However, as soon as I touch Control_L or Control_R at the same time,
something weird happens. Here's the output for Control_L + 1:

   KeyPress event, serial 1684, synthetic NO, window 0x4200001,
       root 0x4b9, subw 0x0, time 4065591518, (117,69), root:(3486,798),
       state 0x14, keycode 10 (keysym 0x31, 1), same_screen YES,
       XLookupString gives 1 bytes: (31) "1"
       XmbLookupString gives 1 bytes: (31) "1"
       XFilterEvent returns: False

but look at what happens for Control_L + 2:

   KeyPress event, serial 1684, synthetic NO, window 0x4200001,
       root 0x4b9, subw 0x0, time 4065592038, (117,69), root:(3486,798),
       state 0x14, keycode 11 (keysym 0x32, 2), same_screen YES,
       XLookupString gives 1 bytes: (00) ""
       XmbLookupString gives 1 bytes: (00) ""
       XFilterEvent returns: False

Note how the keysym is correct, but then XLookupString and/or
XmbLookupString instead return the empty string.

This happens whether I load the US or the DE xkb map, using
setxkbmap.

Do you have any idea what might be going on?
