Yes, I don't believe this is a Libreboot issue. You mention you use your
machine for terminal use, web and email. Does your symptoms only affect your
terminal session by any chance? That is when it occurs can you still input
via the keyboard to your browser etc. If it only affects your terminal
session perhaps you inadvertently hit C-s (that is the CTRL key plus s). This
is a bash command to suspend the output. If you then hit C-q this will resume
output again to your terminal and you should see anything you may have typed
while the output was suspended suddenly re-appear.
I too have a Libreboot X60s and do recall a similar issue when I first got
the machine. I can't recall now if it was me inadvertently suspending bash or
another cause. Suffice to say I no longer experience this issue. So if it is
not a suspension of bash output perhaps you are running an older version of
Libreboot.
What version of Libreboot are you running out of curiosity? I'm on the
20150208 release as I still run Trisquel 6. The latest release 20150518
removes the powertop scripts for Trisquel 6 as it is considered now obsolete.
I intend to upgrade to Trisquel 7 at some point and then this latest
libreboot release.
Hope this helps.
