[Android Q&A, Help & Troubleshooting] NotaNorthKorean:
Hello,

I'm trying to run an X server on my tablet, but it does not launch. The X binaries and libraries are from a 32-bit CentOS ROM I downloaded (Mirror list: http://isoredirect.centos.org/altarch/7/isos/armhfp/); I have the contents of the ROM in /data/local with symlinks to parts of it (e.g. /lib). Componenets of GNU Coreutils like Bash, among others work just fine, so I do not believe any parts of the CentOS ROM are causing problems. Running startx through an ADB shell might not work, so I've been looking for a way to run it on the tablet's screen without success.
