If you call getting a logfile a challenge, then I guess so I'm guessing you don't have a console because you upgraded from Lakka or whatever. You need "tty" in the kernel commandline (i.e. /flash/syslinux.cfg or /flash/EFI/BOOT/syslinux.cfg for EFI). My builds have that by default when you do a new install. Swapping the harddrive won't work because /var is on tmpfs, but you will be able to edit syslinux.cfg.
I use different HDDs for lakka and LE so it is not the problem...
I burn your build to my flash USB, plug into PC, boot from flash, install LE in HDD, after installation a reboot message appears. After rebooting, LE splash screen appears and then xorg error prompts. If I try to enter console during booting, only cursor appears and then xorg error in every console. If I try to open console after error prompts, just cursor blinking and no text input response.
I understand I need to access "/var/log/Xorg.0.log" to know what is happening, but I don't know how... How do I tty in the command line? using installation USB? Maybe using "live" version instead of installing in the HDD would help?
