After fixing a few bugs, the #rootless #kali #linux installation via #Termux and #Kex worked out pretty well. Not sure if i can fix the scaling a bit, but so far pretty useful. Thanks to #DavidBombal (not sure if he wants to be tagged) for his informative video.
Nvm, #kali has a #hidpi mode. Now it's perfect. Gonna setup my laptop later to be able to connect to it.
