[Trisquel-users] Re : Suspend / halt not working anymore after a Software Updater launch

[lcerf]

You can boot the previous version of the kernel from the "Advanced options"  
(or whatever it is called), an entry in GRUB's menu (displayed before the  
operating system starts) and confirm that the latest version of the 4.4  
kernel is the problem.  If you explicitly removed that previous version (it  
is not automatic), then reinstall it first: the package is  
"linux-image-4.4.0-141-lowlatency" (well, assuming the update before the one  
that brought you version 4.4.0-142 was not long before).

If, indeed, suspend works on the previous version, then you could, of course,  
stick to that version, e.g., removing both "linux-image-4.4.0-142-lowlatency"  
and "linux-image-lowlatency" (and "linux-lowlatency", if installed).   
However, not having an up-to-date kernel is security-wise, concerning.  That  
is why, if I were you, I would install the latest 4.15 available in the  
repository, reboot, and see if suspend works.  If you really want a  
"lowlatency" kernel (e.g., for music creation), then install the  
"linux-lowlatency-hwe-8.0" package (in Trisquel's repository).  Otherwise,  
install "linux-generic-hwe-8.0".
