gnu: xorg-server: Apply tearfree patch for modesetting driver.
Much of the modern Linux video stack depends on using kernel modesetting (KMS)
drivers. Because of this, not much effort has been put into the legacy stuff,
which have grown less supported and more buggy. Unfortunately, the
modesetting Xorg driver didn’t initially have support for tear-free
video (which most legacy drivers did), requiring additional software -- a
compositor -- to fix this. Sadly, there’s no good option for a compositor --
they all require hardware-specific tweaking and tuning, and tend to be quite
buggy.
Support for a "TearFree" option merged in 2022[1], but there hasn’t been an
Xorg release since it was merged.
This PR applies the patch from that MR to the last release. It required a
one-character edit to apply cleanly, necesitating inclusion in the Guix repo.
I tested this on bare metal and it appears to work well.
