mesa-opencl-icd vs ocl-icd-libopencl1
Bonjour,
Je n'arrive pas à comprendre la différence entre le paquet openCL mesa mesa-opencl-icd et le paquet ocl-icd-libopencl1. Si j'essaye d'enlever ocl-icd-libopencl1, j'obtiens ça :
sudo apt remove ocl-icd-libopencl1

Souhaitez-vous continuer ? [O/n] Un peu violent !!! Il semble que ça m'enlève tout le meta paquet ubuntu studio...
J'ai aussi installé le paquet mesa-opencl-icd, mais quand je fais un clinfo j'obtiens ce retour :
