I've installed fossa64 9.5 on multiple laptops without any issues. Two of the laptops have overheated when the default screen saver initiates. Here are pertinent specs:
-Puppy fossa64 9.5 frugal install
-laptops have standard video chips, no nvidia or other enhanced video
-cpu cooling fans are clean and unobstructed
-normal idle tempertures=45-50C
-cpu cooling fans start to increase rpm within 30 seconds and overheating occurs within 3 minutes of screensaver activation
Laptops:
-Dell Latitude E6430, cpu=Intel I5-3320, overheats to 70C plus
-Lenovo X220, cpu=Intel I5-2410, overheats to 90C plus
Other information:
-running menu>setup>Screen/Graphics Wizard>Screensaver, checking, Enable screensaver, Blank the screen, Allow exposures also results in overheating. HOWEVER, when unchecking Blank the screen it does not overheat the cpu.
-neither laptop overheats when using Slacko 6.3 or Dpup Stretch 7.5 default screensavers (looks like the same script).
This is worth noting since the screensaver is enabled by default and the overheating, particularly on the x220, could damage the hardware.
I've solved the problem on these computers as follows:
-disable the default screen saver
-modify the file, autoshutdown_daemon, to do a suspend
-enabling autoshutdown by running: menu>system>puppy event manager>power, then setting
the inactivity interval
