Maybe this is i915/i965 intel driver related. If someone with an in
intel IGP could reproduce this. I have xserver-xorg-video-intel
installed by the way. With not mentioning "intel" explicitly as the
driver in xorg.conf doesn't it automatically uses modesetting or
glamorgl?

Just had the idea to unload "glx" and see if I can Disable Composite
without crashing Xorg / startx / xinit.
It works!
Here's my xorg.conf:
Section "Module"
Disable "glx"
EndSection
Section "Extensions"
Option "Composite" "0"
EndSection
I'll put my resulting Xorg.0.log as an attachment.

I suspect libglx0 (transition from libgl1-mesa-glx to libglx0)
Because now we have:
/usr/lib/x86_64-linux-gnu/libGLX.so.0.0.0 (from libglx0 in bionic, new with
bionic)
instead of:
/usr/lib/x86_64-linux-gnu/mesa/ld.so.conf
/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1
/usr/lib/x86_64-linux-gnu/mesa/l
Now I remove +s bit from /usr/bin/X, /usr/bin/xinit, /usr/bin/startx,
/usr/bin/Xorg and tried to run Valgrind with it. Honestly I have no idea
about debugging. I just know that valgrind and strace can be somehow use
for it. Hope this helps!

Title:
[bionic] xserver / startx crashes with Composite Disabled in xorg.
Another interesting thing with this xserver-xorg-core is that it ignores
Option "AIGLX" "Off" in the ServerFlags section and initializes AIGLX.
This also hasn't happened before bionic.
And the crashing (see the Xorg.0.log in my previous post) seems to
happen right where normally some AIGLX initial
