LibreELEC 8 and earlier versions (back to the old OpenELEC days) contained an ugly kernel patch to get the Zotac remotes working. This hacky patch was causing issues though and broke on every other kernel update.
So we decided to drop most of the crappy hacks so we could find out if there are actual issues that need fixing and if there are (like with the Zotac remote) then fix them properly - which means communicating with the Linux kernel developers and getting issues fixed in official Linux kernels.
Doing it this way means all Linux users profit from the fixes (eg if you run Ubuntu you'll get the fixes, too) and we don't have to do the tedious work of adapting our own fixes after each kernel update. So it's a win-win situation for all of us.
It looks like Sean (the Linux kernel maintainer for the IR remote stuff) has picked up my Zotac fix and it should appear in official 5.1 kernels syoung/media_tree.git - media_tree.git RC development tree
The fix is also included in current Milhouse testbuilds and of course will be included in the next LE9 update as well.
so long,
Hias
