Hi, welcome to CHDK Wiki! Thanks for your edit to the Drivelapse page.
I saw your changes on the timelapse script and you finally solved the display_off problem on my A2000. Many thanks! I made another pass after your changes. Since we're accumulating several different versions of the script, I decided to put my copy online at https://github.com/alfredopironti/chdk-scripts/blob/master/lapse.lua
Please feel free to keep cooperating on that CVS (I think it's better than a wiki ;-) )
