Waking from sleep I am greeted just by a blinking underline ( _ ). Pressing any key There’s a message stating that the screenlocker is broken, to switch to a console and to type loginctl unclock-session 2.
If I switch to a console there’s just text scrolling, I cannot type anything. REISUB is the only way out.
I must add that when I first installed EndeavourOS, at boot time I saw a message stating that splitlock was causing a kernel crash. Googling this I found a recomendation to add this boot parameter split_lock_detect=off
Since I had selected the btrfs filesystem, I looked for ways to include this boot parameter. None of the suggestions to add this parameter worked. So I re-installed, using GRUB because I knew that I could do that in GRUB, so I added this to /etc/default/grub : split_lock_detect=off
The message about splitlock crashing the kernel was replaced by, splitlock off.
I also selected XFS for the filesystem.
So GRUB is still useful

That’s all folks 
Adding this parameter mem_sleep_default=deep to GRUB has fixed the issue.
