I hope you find a solution. I grew frustrated with the immutable desktop function of the SteamDeck, so I installed holoiso instead of SteamOS. Seems nearly identical, except that I can actually use the computer in desktop mode. Sleep is buggy now. I miss how well sleep worked in SteamOS.
Anything by Andrew W.K., but “Music is Worth Living For” seems apropos https://cf.piped.video/watch?v=-CBTyi-ovO8
