Bug description:
  I have a laptop with both AMD Raven and Nvidia GTX 1050 video
  adapters. 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

  ** Message: 12:33:29.273: PRIME: No offloading required. Abort
  ** Message: 12:33:29.273: PRIME: is it supported? no

  And then a blank window...
