I had lots of problems with the previous version when turning the TV off/on while it's running, like losing keyboard access (no focus) until you use the mouse at least once and it updating the display settings every time. Hope it's getting better now.

TBH the keyboard focus issue is happening on most Login Managers and DEs, so it's not really their fault. I will try it out some time, until then I keep using my SteamOS install.
