First: thank you for your work! it looks great.
i think there is an issue in #129 and #204 with the lcd screensaver.
it shows always: 00:00

What is the last build when it worked correctly? You've told me it worked in #1116 (2017) but doesn't work in #0129 (2018), somewhere in between is presumably the build when it stopped working - if you can identify that build maybe it will help identify the breaking change.  

 It looks like that the #1230 (2017) is ok and #1231 (2017) not.
perhaps "New 4.14.10 kernel" or too much new years eve party ?

I downgraded from 1231 to 1230 (not my preferred method) and its ok again.
