I need to keep the display on the whole time and considering how slow my internet connection is, it is a lot. I am surprised that there is no option to download the games while in standby or sleep mode.
I know that the Deck lowers the brightness but it seems to be awfully ineffective and of course I am also worried about display burn in.
I haven't done this myself, but I assume you can turn off the display in Desktop Mode. I assume somewhere in the "normal" Linux settings there will be the usual Turn Screen Off after ... and Go To Sleep after ... You could just set the screen to turn off after 5 mins, then set sleep to never and that should do it.
In desktop mode there is an easier way for the last part - click the battery icon in the taskbar, then click "temporarily don't sleep". Screen brightness can also be set in the same area
No quick solution for turning the screen off though AFAIK...
