Hi Daiane,
sure , the patch is attached to this mail (let me know if I must to
change it)
About the cinematicexperience + eglfs dependecies:
With the only inclusion of cinematicexperience the "EGL..." error come
out , so i must to add the "amd-gpu-bin-mx51" package to have all the
necessary library on my fs.
Bests Regards
Gianluca
