If you didn’t specify anything, the game should run on > the “primary” GPU by default, which quite often tends to be the Intel GPU. In fact the games runs with Nouveau and DRI_PRIME=1. It does not work after to do the reclocking => the game’s process exist but the game’s window does not appear. Are you French, if yes it’s easiest to explain : Lorsque je lance la commande pour faire le reclocking, je n’ai plus accès au prompt, comme si la commande continue de travailler en arrière plan. Si je verifie l’état de pstate dans une autre commande, le reclocking a l’air d’avoir été fait.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
