Mais il faut savoir que chaque conky est personnel, par exemple pour que le mien fonctionne j'ai installé quelques paquets supplémentaires:
-redhat-lsb
-lm_sensors et lm_sensors_lib
-hddtemp

De plus pour les infos sur ma carte nvidia, j'ai re-compilé conky avec l'option nvidia (la version fedora ne l'ayant pas, driver propriétaire n'est pas dans la philosophie de fedora).

Ce n'est pas compliqué, mais cela demande un peu de temps pour avoir un conky qui te plaise.
