Hey @FinBob,
TL;DR
Fix for only native screen res
Fix for scaling : The important fix is this: echo Xft.dpi: 144 | xrdb -merge
I had the same issues on my V54, wrote a HCL with fixes for most of them. My only “issue” now is that the performance is somewhat bad, was not thinking to get much out from it but just browsing is pretty bad. Video playback in browser is impossible unless you have the window small.
