POSSIBLE WORKAROUND
Symptom - Librem-14 screens, mouse cursor, etc., crash/freeze/hang.
Tap Fn-Esc - should instantly sleep but nothing happens ## showing the system is unresponsive.
Tap Fn-F4 six times - keyboard glow backlight intensity should change ## showing the Embedded Controller (EC) responds.
Wait - long enough to launch an ssh session into the Librem-14 and type $ top -n1 ## showing Xwayland burning 100% CPU.
The fans roar. If you’re lucky, after a while the screens go black, ssh stops responding and the battery LED starts snoring ## showing that Fn-Esc eventually slept the system after all.
Tap Power to wake the sleeping system - everything seems normal until the next crash/freeze/hang which could be minutes away.
Peace

P.S. Reporting these frequent crashes of a brand-new Librem-14 to Purism got advice to wait a few months for the next PureOS release. Looks like an Xwayland bug which was fixed last winter…
