These are simple Launchpad scripts which change when the Kindle goes to sleep and the screensaver on the Kindle starts. The default is '10 mins'.
Here are my scripts. I actually have several set to Launchpad shortcuts, from 15 minutes to 120 minutes:
screensaver_timeout.ini
Code:
[Actions]
; Screensaver Timeout
S A = !source /mnt/us/launchpad/screensaver_timeout_15.sh
S B = !source /mnt/us/launchpad/screensaver_timeout_20.sh
S C = !source /mnt/us/launchpad/screensaver_timeout_30.sh
S D = !source /mnt/us/launchpad/screensaver_timeout_45.sh
S E = !source /mnt/us/launchpad/screensaver_timeout_60.sh
S F = !source /mnt/us/launchpad/screensaver_timeout_90.sh
S G = !source /mnt/us/launchpad/screensaver_timeout_120.sh
S X = !source /mnt/us/launchpad/screensaver_timeout_reset.sh
screensaver_timeout_15.sh (no need to show the 20, 30, 45, etc ones)

I used the code by pilotdrh2003, found here:
https://www.mobileread.com/forums/sho...postcount=1210, and, thanks to WS64, I altered it a small bit (so it goes to the appropriate directory on firmware 3.3 (uncomment the 3.X and comment the 3.3 section if required). Here, there are Launchpad shortcuts you can use to do it. Easy peasy. So far so good. If you have any problems, feel free to share.
Note: if you have a /mnt/us/screensaver-timeout file with a custom screensaver timeout (in seconds), it will override whatever Launchpad shortcut time you use when you run one of the shortcuts.
