SteamOS Has Dropped Support For Suspend
jones_supa writes: As pointed out by a Redditor, it seems that suspending the machine is not officially supported by SteamOS anymore. A SteamOS user opened a bug report due to his controllers being unresponsive after a suspend cycle. To this, a Valve engineer bluntly reported that "suspend is no longer supported". He further explained the issue by saying that given the state of hardware and software support throughout the graphics stack on Linux, the team didn't think that they could make the feature work reliably.
Windows had gotten a lot better these days. But a few years ago suspend often failed on windows. OS X however always worked well, but then they designed their own hardware which makes this a lot easier.
