I don't know how to turn off EXA (I didn't even know what this acroym

problem by switching to modular-xorg-server version 1.4.2 which is in
pkgsrc-wip.
Only one problem is still left. When switching to console and back again
to X11, I can't use the X11 applications any more. Only a xorg server
restart helps. But that's a lot less worse than random signal 11's :)

I had some sort of same troubles on latest xorg update.
To check what is it:
uncomment Option "NoTrapSignals" from /usr/pkg/xorg/lib/X11/xorg.conf
and if it coredumps on libexa.so you can select XAA in your xorg.conf
in this way:
Section "Device"
        [...]
        Option      "AccelMethod"    "XAA"
EndSection
I've fixed in such way my problems.

Bye,             \fer
