About 2 years ago I found a solution to a petty annoyance which has since stopped working:

========= SCRAPER REMOVED AN EMBEDDED LINK HERE ===========
 Note: reguarding the"repetitive error text on tty1:
S. H. Engine unavailable
side issue below...
Thanks to masinick's reply (
========= SCRAPER REMOVED AN EMBEDDED LINK HERE ===========
url was:"antix.freeforu ms.org/post24495.html#p24495"
linktext was:"antix.freeforu ms.org/post24495.html#p24495"
====================================
) I found when the same error message happened in the console(s) with a subsequent antiX install to my gateway (amd_64) laptop I could at least eliminate the error messages from the consoles via:

Code: Select all

 update-rc.d acpi-support stop 3 . 
update-rc.d acpid stop 3 .
and rebooting... Don't really understand acpi well enough to be sure which of them I needed to turn off, so I did both.[/color]
I can't really say when it stopped working because I multiboot an assortment of Linux distros on more than one computer. and it's only recently that I happened to spend some time in the virtual console under antiX on the gateway laptop. (never got this error with other distros etc...)

But since the above fix no longer works, I dug in a bit deeper, and located the script that masinick had indicated was the source of the error.

And accordingly edited the file:
/usr/share/acpi-support/eeepc-acpi-scripts/lib/shengine.sh

to add $DISPLAY based conditional branching to the two lines containing:

Code: Select all

notify error 'S. H. Engine unavailable'
Specificly, I changed this:

Code: Select all

         *)notify error 'S. H. Engine unavailable'
        esac
    else
        notify error 'S. H. Engine unavailable'
    fi
to this:

Code: Select all

         *)  if ["$DISPLAY" ="" ] 
                then
                 dummY=$DISPLAY
                else
                 notify error 'S. H. Engine unavailable'
                fi;;
        esac
    else
        case $DISPLAY in
               "")dummY=$DISPLAY;;
                *)notify error 'S. H. Engine unavailable';;
        esac
    fi
This seems to work. But I don't really even have a clue why I need the eeepc-acpi-scripts package in the first place, And to be honest, I don't know if the $DISPLAY switching logic is appropriate for this script. I also note that I didn't know if the edited function failing to actualy"do" something could cause an error or not, hense the"dummY=" lines...

So Like the subject asks, Is this safe?
