I wanted to test the new game mode in Ubuntu 20.04, and noticed that only the AMD Raven actually works. To do the test, I tried launching a terminal and running gxgears, both in a normal way, and then using the "start using dedicated video adapter" (or whatever it really is in English) option in gnome-shell. Using the standard video adapter (probably the AMD Raven), it works, but slowly. Using the dedicated video adapter, I get the following: juloliv@juloliv:~$ glxgears X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 152 (GLX) Minor opcode of failed request: 3 (X_GLXCreateContext) Value in failed request: 0x0 Serial number of failed request: 25 Current serial number in output stream: 26 NB: in both cases, I tried launching nvidia-settings and got the following: juloliv@juloliv:~$ nvidia-settings ERROR: Unable to load info from any available system (nvidia-settings:9213): GLib-GObject-CRITICAL **: 12:33:29.270: g_object_unref: assertion 'G_IS_OBJECT (object)' failed ** Message: 12:33:29.273: PRIME: No offloading required.
