From bugzilla bug 13467¹:
The modeline2c script is the only part of the Xorg server that requires Perl.
[This] is a simpler replacement that works with any normal AWK.

We free the ValuatorClassRec quite regularly. If a SIGIO is handled while
we're swapping device classes, we can bring the server down when we try to
access lastx/lasty of the master device.
These hints allow an acceleration architecture to optimize allocation of certain
types of pixmaps, such as pixmaps that will serve as backing pixmaps for
redirected windows.
In a multihead setup, if only the first screen can be
initialized, but the second screen is mentioned first in the
ServerLayout section, the xf86InitOrigins() function will crash
because the screen referred to in the e.g. "RightOf" part is
non-existent.
This makes the root visual a GLX capable visual again and adds a GLX visual
for the COMPOSITE ARGB visual cleanly (as opposed to the hack we had before).
Call ProcessOtherEvents first, then for all keyboard devices let them be
wrapped by XKB. This way all XI events will go through XKB.
Note that the VCK is still not wrapped, so core events will bypass XKB.
(cherry picked from commit d627061b48)
Hide getline call by checking for glibc. If not, use fgetln instead. Even
though this section is now #ifdef'ed for linux only, this should help make
it more portable if non-linux folks end up wanting it.
It contains static paths, fails to build on non-glibc, and apparently just
exists to support distributions managing binary drivers and open-source drivers
together. Also restores previous code for fallback to vesa if nothing is
detected.
Right now we default to "all" which gives us a situation much like before,
but when the "typical" option is implemented, we can change the default and
reduce the number of visuals the GLX module bloats the X server with.
If none is present, a default one will be created. This will be attached
to either the first device section in the xorg.conf (allowing you to
specify something like using EXA without having a screen section) or a
default screen section if none is present in the file.
This will allow the screen to not explicitly have a device section. If
this is the case and there is a device section in the xorg.conf, the first
one will be used. If there is no device section at all, a default one will
be created that loads the automatically determined module.
This is what we're currently shipping in Debian. Enables the ability for
drivers to ship a text file listing PCI ID's they support, and have the
server read them on startup when no driver is specified. This works, but
isn't the final solution.
DGAStealXXXEvent modified to take in device argument.
The evdev driver only sends one valuator when only one axis changed. We need
to check for DGA either way (xf86PostMotionEventP), otherwise we lose purely
horizontal/vertical movements.
Note that DGA does not do XI events.
