Part Number: SK-AM68
Other Parts Discussed in Thread: AM68,
Cold boot time with these simple changes reduces boot time to about 13 seconds, but Weston sometimes fails to start.
Attaching logs of working vs not working.
Key line is:
[FAILED] Failed to start Weston, a …mpositor, as a system service.
I can run systemctl restart weston and it shows the desktop.
