AIGLX: Suspending AIGLX clients for VT switch

[Victor Sudakov]

Dear Colleagues,

I use two Xservers on my desktop box (FreeBSD 11.2):

[vas at vas ~] ps axww | grep xin
70999 v1- I         0:00,00 xinit /home/vas/.xinitrc -- /usr/local/bin/X :1 -auth /home/vas/.serverauth.70986
69720 v2  I+        0:00,00 xinit /home/nk/.xinitrc -- /usr/local/bin/X :0 -auth /home/nk/.serverauth.69707
36786  8  R+        0:00,00 grep xin
[vas at vas ~] 

One is my Mate session and the other my wife's one.

We switch between them with Ctrl+Alt+Fn. Sometimes I also need to switch
to the vt text console with Ctrl+Alt+F1.

The problem is that sometimes Ctrl+Alt+Fn just freezes the GUI for good,
and I have to ssh to the box from my son's computer and issue "sudo killall xinit"
and then start "startx" again.

Sometimes after I kill the xinit processes I see the following message:

(II) AIGLX: Suspending AIGLX clients for VT switch

I presume that something is preventing the vt switching from happening. 

Can I configure startx/xinit/xorg whatever so that if I press
Ctrl+Alt+Fn, the virtual consoles should be switched unconditionally
without "Suspending AIGLX clients" or whatever the xservers are trying
to do. I'm the boss after all. If vt switching crashes some X client, I'm
fine with it.

It is also remarkable that now I cannot kill the Xserver with
Control+Alt+Backspace any more. How can I regain this possibility?
