Hmm, `xkbcomp :0` gives no output.
I'm currently using setxkbmap to alternate between different keyboard
layouts. The working configuration is:
setxkbmap us,ru -variant ,phonetic \
-option grp:lwin_toggle,grp_led:scroll
(This is done from .Xsession, but can also be used from any X terminal
like xterm or rxvt.)
The non-working configuration is:
setxkbmap us,ru,gr -variant ,phonetic,polytonic \
-option grp:lwin_toggle,grp_led:scroll
I've tried it with non-polytonic Greek, and it also works:
setxkbmap us,ru,gr -variant ,phonetic, \
-option grp:lwin_toggle,grp_led:scroll
Basically, I use the left 'windows' key to toggle between us, ru, and
gr. The ctrl-alt sequence doesn't work when I specify gr(polytonic) to
setxkbmap, regardless of whether the current layout (selected by lwin)
is actually gr(polytonic) or not. I do get the right characters in
gr(polytonic); the only obvious problem is that the vt-switch sequence
doesn't work (it inserts carets and other symbols instead).
Anyway, I tried to capture the keyboard events using xev, hopefully this
will help you track down the problem. The following is from the
non-working configuration (run xev, type ctrl-alt-F1, which does
nothing, and quit xev):

In the non-working configuration, the F1 is received by xev, but in the
working configuration, the F1 is not received by xev (probably
intercepted by the server and interpreted?).
