I'm using xubuntu 14.04. I'm having a problem when pressing some keybinds (specifically with some keycodes). Thus, show you the result of xev when pressing first Alt_R and then Alt_L.
KeyPress event, serial 37, synthetic NO, window 0x1e00001,
root 0x9d, subw 0x0, time 1289711, (-144,-233), root:(446,267),
state 0x0, keycode 108 (keysym 0xfe03, ISO_Level3_Shift), same_screen YES,
XKeysymToKeycode returns keycode: 92
XLookupString gives 0 bytes:
XmbLookupString gives 0 bytes:
XFilterEvent returns: False
KeyPress event, serial 37, synthetic NO, window 0x1e00001,

XmbLookupString gives 0 bytes:
XFilterEvent returns: False
My problem comes after this. The combination with some letters is not working. Let's say I keep pressed both alt keys, and then press q. Then following line should appear but it's not appearing at all:
KeyRelease event, serial 37, synthetic NO, window 0x3600001,
root 0x9d, subw 0x0, time 1711270, (14,-202), root:(608,272),
state 0x8, keycode 24 (keysym 0x71, q), same_screen YES,
XLookupString gives 1 bytes: (71) "q"
XFilterEvent returns: False
Nothing is being displayed with q (also with e, t and some others) and I would like to know why, because I use some of these key combinations for some keybindings in some programs.
Long story short. Some keybindings are not working because some combinations of keycodes are not working (it's keycode specific, I used other keyboard layouts to test it).
I also add you the information given by setxkbmap -query:
