Hello,

That's the atomic modesetting feature. The basics have landed, Daniel
has a remaining series brewing for restoring the composite bypass path
and using hardware planes. What hasn't been worked on yet AFAIK is the
TEST_ONLY feature of atomic modesetting. Essentially, before we take an
output configuration into use, we should do a TEST_ONLY commit to see
if it possible before-hand, rather than failing after the configuration
is used. TEST_ONLY would allow iterating through different
configurations to see which ones should work.

You run a distribution you like and are familiar with. You can use
distribution packages for all components you don't need to modify and
are new enough. Set up a prefix under your home directory where you
install all the software you need to build manually. Getting Weston
built manually and running from a prefix directory would be the first
step.

Atomic modesetting is exclusive to the DRM-backend, so you should be
prepared to run Weston from the virtual terminal on "bare" hardware. If
something goes wrong, it is very handy to have another computer to log
in remotely to diagnose and recover. Virtual machines like qemu are not
always suitable for testing the DRM-backend.

Also note that NVIDIA proprietary drivers are not suitable for working
on Weston.

These I cannot personally help with, sorry.


Thanks,
