This happens to me more than I'd like to admit, but sometimes I don't notice the power getting low since it only shows up in my status bar, then the computer just quits. I'd like a big alert that warns me before this happens. Is there any way for it to alert me? Ubuntu has a nice popup that tells you it's getting low.
write a script!
then cron it to run every few minutes or so. But yeah, if you can do it through the GUI, that's probably a much better way of doing it.
You should open :
and search for percentageText - subsequently, you ought to be able to add a pop-up message or alert.
