Public bug reported:

Please change retroarch package dependencies to downgrade libgamemode0
from recommends to suggests.

When libgamemode0 and gamemoded packages are installed on my Ubuntu
system they don't work or run correctly because of my Intel J5040 CPUs
and on-board GPU since gamemode executable and services terminate saying
that they are not needed to run since there is no need for CPU core
pinning or parking and I don't have an nVidia or AMD video card nor
processor, just regular Intel.  Thus retroarch tries to access the
libgamemode0 library and fails with a core=dumped crash and also throws
D-bus errors.

Also, because the retroarch package recommends libgamemode0 package
doing a Unbuntu do-release-upgrade forcefully installs the
recommendations thus creating the problem on release upgrade even when
previously the retroarch package was installed without the recommends to
avoid this problem so this broke RetroArch for me again when I did a
release upgarde.

Homepage: https://github.com/FeralInteractive/gamemode
Description-en: Optimise Linux system performance on demand (host library)
 GameMode is a daemon/lib combo for Linux that allows games to request a set
 of optimisations be temporarily applied to the host OS.
 .
 The design has a clear-cut abstraction between the host daemon and library
 (gamemoded and libgamemode), and the client loaders (libgamemodeauto and
 gamemode_client.h) that allows for safe use without worrying about whether
 the daemon is installed or running. This design also means that while the
 host library currently relies on systemd for exchanging messages with the
 daemon, it's entirely possible to implement other internals that still work
 with the same clients.
 .
 GameMode was designed primarily as a stop-gap solution to problems with
 the Intel and AMD CPU powersave or ondemand governors, but is intended to
 be expanded beyond just CPU governor states, as there are a wealth of
 automation tasks one might want to apply.
 .
 This package provides the host library for gamemode. It is an internal
 library which communicates with the daemon.

Description-en: Optimise Linux system performance on demand
 GameMode is a daemon/lib combo for Linux that allows games to request a set
 of optimisations be temporarily applied to the host OS.
 .
 The design has a clear-cut abstraction between the host daemon and library
 (gamemoded and libgamemode), and the client loaders (libgamemodeauto and
 gamemode_client.h) that allows for safe use without worrying about whether
 the daemon is installed or running. This design also means that while the
 host library currently relies on systemd for exchanging messages with the
 daemon, it's entirely possible to implement other internals that still work
 with the same clients.
 .
 GameMode was designed primarily as a stop-gap solution to problems with
 the Intel and AMD CPU powersave or ondemand governors, but is intended to
 be expanded beyond just CPU governor states, as there are a wealth of
 automation tasks one might want to apply.
 .
 This package is a metapackage including everything that is necessary to run
 gamemode-enabled games or to enable it by hand for applications. It includes
 a program called '/usr/games/gamemoderun', which can invoke gamemode into any
 application. It also includes '/usr/games/gamemode-simulate-game', which
 invokes gamemode, sleeps for 10 seconds and then exits. This allows you to
 test whether gamemode is working properly on your system, it will return
 gamemode's error message if something went wrong, otherwise it will exit with
 a 0 status.
